It fulfills a requirement in the professional recording industry for the ultimate quality in tape recording. The continued improvements in records, tapes, and playback equipment revealed deficiencies in original master recordings. The 3M Brand Professional Audio Recorder overcomes these problems and provides improved master music tapes -- improvement; readily discernible by ear. The 3M Brand Professional Audio Recorder provides significant improvements over present professional audio recorders in three basic areas. Probably the most import of these is the improved dynamic range, as much as 15 db. The second area of improvement is a new tape drive system that reduces flutter to half that present in other tape transports in the audio field. Third, the entire system affords an operating and editing ease unmatched by any other tape recorder. Other improvements. not readily apIJarent. are an increase in the long-term reliability due to the exclusive use of silicon transistors in the electronics assemblies plus the simplified tape-drive system. The 3M Brand Professional Audio Recorder achieves its outstanding performance from such patented techniques as the 3M Dynatrack system of recording and playback, and the Isoloop tape drive system; plus experience gained from over a decade of design and manufacture of Mincom, state-of-the-art, aerospace tape recorder-reproducer systems. FUNCTIONAL DESCRIPTION Functionally, the 3M Brand Professional Audio Recorder operates on the same basic principles as any other tape recorder. These principles are covered in many textbooks and will not be presented in this manuaL. As stated, the features that give this recorder its outstanding performance are the Dynatrack technique of recording and reproducing, and the Isoloop tape drive. DYNATRACK ELECTRONIC SYSTEM l r The Dynatrack technique improves signal-to-noise ratio and expands the recorded dynamic range of tapes by as much as 15 db over other recorders. These improvements are the result of a revolutionary, yet relatively simple, diversity recording and reproducing system. The diversity system feeds the same signal through two recording heads, mounted parallel in the same head stack, and records two separate, full band information tracks simulatneously. Every channel in the Dynatrack recorder (one channel for mono, two for simple stereo, or three for [ r M23 RRM 2-69 1 multi-channel stereo, or stereo and mono together), r ecords two information tracks. One track of a channel is recorded at a norma 1 l evel, following NAB r eco rding standa r ds . The other track, recording the identical information records signals at a higher leve l (mor e r ecording amp lifier gain), emp loys a preemphasis c urve rising 15 db fr om 400 H z to 15,000 Hz (figur e 2A). The track recorded at normal l eve l can h and le high e r signal l eve l s , so it is ca lled the H track. It w ill r each distortion l eve ls in accordance with standard VU meter practic e and with NAB r espo ns e and distortion specifications. The other t r ack, with its preemphasized, highe r-l evel signal, is better suit ed for recording signa l s of a much l ower sound l eve l , so it is called the L track. This L track w ill go into over l oad distortion at high-frequency signal l eve ls considerab ly below 0 VU on th e meter. But whe n r ep r od ucil)g very soft sounds, wh ich are usually l ost in tape noise when r ecorded at no r mal levels, the L track wil l put out a clean, undistorted signal at a l evel well above tape noise (figur e 3). Once thes e two tracks are r eco rd ed as described, the only r ema ining problem is to a rrang e for playing ba ck th e prop e r track -- that t r ack with minimum noise or minimum distortion -- and at th e proper signa l l eve l.

The circuitry is designed and calibrated so that the signals from the L track are reproduced up to the point where the signal approaches 1% total harmonic distortion. At this point the output is taken from the H track, which has a signal recorded as much as 15 db below the 1 % distortion point. Now, the level of the output signal can continue rising until it reaches the normal maximum,as indicated on the VU meter. This track transfer from L to H occurs much faster than the ear can detect so that sudden steep transients of high volume are cleanly reproduced without any audible distortion. Wnen the signal on the L track drops below 1 % distortion, the electronic circuit automatically transfers the signal from the H track back to the L track in approximately 30 milliseconds. NOTE No switching occurs on signals below 400 Hz, as tape noise rarely intrudes on signals below this frequency. M23 RRM 2-69 3 To equalize playback levels of both the Land H tracks, there is a deemphasis network in the play circuit of these preamplifiers, providing the exact opposite of the preemphasis network in the recording circuitry (figure 2B). A continuous visual check as to which track is being reproduced is provided by th e pilot lamp in the L track preamplifier section of the electronic assembly. When the lamp is glowing, the L track is being reproduced; when the lamp is out, the H track is being fed to the output. This automatic track transfer system is a completely electronic system; no m e chanical relays, switches, etc., are used (figure 4). All electronics are solid-state, assuring long term reliability and accuracy of performance. Also, as the Dynatrack recording technique is completely electronic, there is no noise involv ed at any frequency, and the system is completely undetectable in use -- except for the increased signal-to-noise ratio and the far greater dynamic range of tapes recorded and reproduced on the 3M Brand Professional Audio Recorder. ISOLOOP TAPE TRANSPORT The tape transport mechanism of the 3M Brand Professional Audio Recorder is derived from designs used in instrumentation recorders, where standards of timing accuracy, and wow and flutter are even more demanding than l TRACK PLAY HEAD J----.

The heart of th'e patented Isoloop tape drive is the' differential capstan, which maintains a constant tape tension within the drive and positive contact of the tape against the heads (figure 5). In addition, the unsupported tape path is extremely short in comparison to standard design tape recorders. This short path reduces longitudinal oscillation to a new low and eliminates the need for ·a series of tape guides to maintain a proper tape path. The tape tension required "to minimize flutter and hold the tape against the heads is generated within the closed loop by the differential drive capstan. The tape drive surface of the capstan is divided into regions of two different diameters. The incoming idler roller is contoured so as to press the tape firmly into the matching "grooves" (of the smaller dialIleter) of the capstan. The outgoing idler roller is shaped so as to press the tape firmly against the "ridges" (of the larger diameter) of the capstan. This differential of capstan diameters constantly tries to extract more tape than is being fed into the loop and creates the necessary tension by means of the slight elasticity of the tape itself. This tape tension is always kept safely within its elastic limits. The Isoloop tape drive, short tape path, and flywheel driven capstan all aid in reducing the flutter of the tape transport to approximately half that found in other professional tape drive systems.

It is availab l e in several standard conso le configurations, as a portable system contained in its own portable case, or unmounted for installation in a 19-inch equipment rack (figure 6). Specia l consoles and cabinets are available on special order. Systems are engineered to fit the us er 's requirements: the number and type of channels, and the mounting and installation to fit the application. Complete installation instructions for eac h of the standard models is given under Installation. Physically, each system cons i sts of a tape transport and electronics as requir ed. Thi~ may be 1 to 8 channe ls of NAB electronics, I to 4 channels of Dynatrack electronics or a combination of both. Any system can be expanded up to the maximum capacity simply by adding additional cha nnels of electronics and c hang ing th e tape width and magnetic heads. EQUIPMENT DESCRIPTION Each tape r eco rder syst em w ill have a tape transport (figure 7) and an electronics assembly (figure 8) for eac h r eco rd and play channel. Also, a sys tem may h av e any of the accessories listed in table 1. The basic tape transport is the same in a ll systems; the on ly difference is in t he tape width, magnetic h eads, and capstan speed. The tape guides and magnetic heads are inst a ll e d as kits depending upon th e number and type of channels. The t ransport is available with either of two capstan sizes . On e of th ese kits accommodates 1 /4 -in ch o r I /2 -in ch tap e . It i s normally furnished in machines that w ill never be expec t ed to use tapes wider than 1 /2 inch. The other kit is intend ed for machines using I-in ch t ape. 'Whil e 1 /2 -in ch and 1 /4 -inch tape can b e run on th e I-inch capstan, the latt e r is l ess co nvenient for threading and editing I /4-inch or I /2 - inc h tape. The electronics assembl y conta in s the e l ectronics r equi r ed for a single channel of NAB or Dynatrack re cord and playback. Each electronics assembly conta ins a plug-in power supply and mete r (th e meter may b e in a remote location), controls and indicators, and as many as seven plug-in circuit boards. Th e r e is an input and an output transformer l oca ted behind the cont r o l panel. A ll electrical connections for each channe l are made on the rear panel of the elect ronic s assembly. The electronics assembly pl u g -in ci rcuit boards are 'numbered I through 9 on the board handle indic ating the slot that the board goes in. Slot 2 is always empty and the meter and power supply is slot 5. To change th e e l ec troni cs assembly between NAB and Dynatrack it is only necessary to c hang e the boards in slot 3 and 8 . The NAB boards have an N on their handle and the Dynatrack boards have a D on their handle. It is also necessa r y, whe n changing b e tween NAB and 6 M23 RRM 2-69 o UNMOUNTED Consists of tape transport and electronics.

L r l r r r r r r c r r r r [ The Professional Audio Recorder is available as an all reproduce (figure 9)' or combination of record-reproduce, and reproduce only system. The reproduce only electronics are contained in a special electronics assembly. Two circuit boards per channel are required. There is a head cable input connector, output transformer, and signal output connector for each channel on the rear panel. The front panel contains a meter, selector switch, phone jack, and power on indicator. The tape transport operates at either of two electrically selectable tape speeds. The most common speeds are 7-1/2 and 15 ips; however, other speeds are available. The electronics equalization is automatically switched to the selected tape speed. The standard transport is equipped to accommodate 10-1/2 inch reels with NAB hub; however, other hubs and reel capacities are available. The tape transport contains the tape motion controls and tape handling controls; plus, it performs certain functions common to all of the electronic assemblies. It provides tape speed equalization control, the source of bias and erase frequency, the A-B transfer function, and control of the record function. The POWER button on the transport controls the power to the entire system.

Immediately upon receipt, inspect the equipment for any shipping damage. If any damage is noticed, notify the carrier immediately. If everything is normal, proceed with the installation. GENERAL As previously described, the system comes in three basic models: console, portable, and rack mounting. Console models are completely connected and ready for operation when unpacked and the power and signal connections are made. The portable models require, in addition to the power and signal connections, interconnecting cables between the tape transport and electronics. The rack mounting models require the same electrical connection as the portable model; in addition, they must be installed in a 19-inch equipment rack. Thi s section contains installation ins tructions for eac h of the three models, plus instructions for each of the standard accessories. LOCATION CONSIDERATIONS The tape recorder system can be installed in almost any location as long as reasonable judgement is used. The system should not be installed in an extremely dusty or damp location. Strong magnetic fields should be avoided, such as from power transformers and tape degaussers. The tape recorder can probably stand high temperatures much better than its human operator; however, if the recorder is to be installed in an equipment rack, it should not be mounted above a chassis with vacuum tubes or anything which generates a large amount of heat. ·.I.·•.• ·. {:: f. The tape recorder system can be remotely controlled. The standard remote control cables are 5 and 25 feet long; however, longer cables can be used. r (t,• . ~: ~\ CONSOLE MODEL INSTALLATION Console models are shipped from the factory ready for operation. They are crated according to standard commercial practices, depending upon their destination. In some cases, the crating may be extensive and the receiver must be careful when unpacking not to damage the equipment or discard any separately packaged accessories. When the equipment IS uncrated and located in its operating position, it only requires power and signal connections to be ready for operation; r r M23 RRM 2-69 25 plus connection of some accessori es. Instructions for making these connections ar e given in the following paragraphs. Dimensions of the standard console models are given In figure 10. RACK (OR CUSTOM) MOUNTING For rack mounting or custom installations the equipment and interconnecting cables are shipped as separate items ready for installation into a 19-inch equipment rack. Figure 11 gives the outline dimensions. Figure 12 illustrates a typical rack mounting installation. Cable connections and signal interface information is presented in the following paragraphs of this section. The e l ec tronics assemblies and transport are packaged according to comm e rci a l practices. In addition, th e transport is contained in a wooden shipping crate. To remove the transport from the wooden shipping crate, pry the top of the crate off. (It is nailed on.) There are cutouts at each end of the crate so that th e tr an sport can be grasped and lifted out. Remove the tape transport from its shipping crate and install it as follows: 1. Position the capstan assist spring for vertical or horizontal mounting, as required. See figure 14. 2. To expose the transport mounting rails, it is necessary to remove the transport front cover plate. This is secured by two screws at the top of the transport and a lip at the bottom. Remove the two screws and slide the cover from the lip. 3. Attach the transport to the mounting rails, using eight 10-32 screws, washers, and lock washers; four on each side. 4. Reinstall the transport front cover plate. The maximum distance between the transport and the electronics assembly is determined by the control and head cable lengths. From the transport connector to the first electronics assembly connector is 36 inches. The remaining connector loops are 12 inches apart. The head cable set is 66-inches long. To install the electronics assembly, open the front cover and attach to the mounting rails with four 10-32 screws, washers, and lock washers. When the ele c tronics assembly and transport are installed, make the cable connections as show n in figure 14, and listed under "Electrical Connections". NOTE Note that each of the cards in the electronics assembly has a number on it indicating the channel. This should be considered when arranging the electronics assemblies. 26 M23 RRM 2-69 1":0:'*1 '"'"""""'"-"'R r~,''''1 r--Y¥j 1'=:;(","1 r + 7% (TO FLOOR, INC ,UDING CAS TERS) I I I--'c=-_;;'"~"I r------:-jI 245/8 G G G 0 o 0 57 (2-CHANNEL) I -- Vo) ~ -- -.D 40 Y2 !- 221/2 J ~ ttjJ _ltJl 49 3614 B 9't. ~I~ 27 J t ~ '" 22Y2 '" J tv -J r-=lII -.

Of course, this equ ipm ent requires no physical installation. The equipment inside is attached to the case by shock mounts. Installation consists of removing the covers and making the electrical connections shown in figure 14 and listed und e r "E lect rical Connec tions," as required. Also, connection of the capstan assist sp rin g must be considered. This is also shown in figure 14. Signal interface information is present under that headin g in this section. ELECTRICAL CONNECTIONS As previously stated, the conso l e model is shipped with all internal cabling connected. It only r equi res that the power cable and the external signal cables be connected, plus accessories such as the edit foot control and remote control. In add i tion, the rack mounting and portable models require connection of the power and contro l cab le, and head cables between the transport and electronics assemblies. All of the cable connections are illustrated in figure 14, and each is detailed in the following paragraphs. Disregard any connec tion that does not apply to your equipment. NOTE The circuit boards in eac h of the electronics assemblies have numbers on them indicating the magnetic head channe ls used to set up the e l ect roni cs at the facto ry . These numbers should match when the eq uipmen t is installed. If they do not, the e l ect ronics should be readjusted before operation . For consistency, the channel numbers, the circuit board numbers, and head channel numbers should match throughout the system. Power and Control Cable Connect the power and control cab l e to the ELECTRONICS r eceptacle on the tape transport and to the POWER receptacle on each of the electronics assemblies. There are two power and control cables us ed . Cab le 23028A050 accommodates four electronics assemblies, and cab l e 23028A060 accommodates eight electronics assemblies. It is not necessary that a ll connector loops o f the cable be connected. If onl y two e l ect r onics assemblies are used, for example, and cable 23028A050 is suppli e d, there wi ll be two extra connectors on this cab l e . 30 M23 RRM 2-69 r r r I, i: '( r r r i' 2 1/2" 3 1/8" ~ -t r l' r j r r r i i" f r r r r r r 'I: ' {!'I CASE FOR 4 CHANNelS OF elECTRONICS OR TRANSPORT AND 1 CHANNel PART NO. 23028A 100-2 OF elECTRONICS CASE FOR TRANSPORT OR 3 CHANNELS PART NO. 23028AlOO-1 OF ELECTRON ICS ,I' I'. r r 1127 Figure 13.

CAPSTAN ASSIST SPRING When the tape transport is mounted in a vertica l position, an assist spring is r equired to hold the capstan motor out of engage ment with the flywheel when it is not r unning . Tpi's spring is stored ac r oss the two lugs on the supply r ee l motor when the tape transport is shipped , or when it is installed for horizontal operation. For v e rti ca l ope r at ion, this sp rin g must be connected betwe en the supply reel motor and the capstan motor brack et. See figure 14. For conso l e and ra ck mounting installations, it is only necessary to c onsider the capstan assist spring when the equi p ment is installed. However , since portable mode l s can be operated either verti c ally o r hori zonta lly, the position of this capstan assist spring must be considered each time the equipment is set up.

INTERFACE INFORMATION All input and output connections and circuitry of the Prof es sional Audio Tape Recorder are based on stand ar d operating procedures in the recording indus t ry. Standard 3-wire XL t ype connectors are used for th e signal inputs and outputs. Cables should b e made up in confo rmance to standard practice as to length, shielding, etc. , with connections as in the following paragraphs. Signal Input To bridge a balan ced studio line, connect the lin e to pins 2 and 3 of an XL male plug (figure 15) and insert it into the SIGNAL IN socket. Connect the ground to pin 1. Input level of -10 to +8 dbm based on the signal level in a 600-ohm line may be emp loyed as a signal source. The load is approximately 20, 000 ohms. An unbalanced line source should be connected to pins 2 and 3 of the connector . Ground should be connected to pins 1 and 2. See figure 15. This prov i des a 20, OOO-ohm bridging input for signal l eve ls as above. Pin 3 could be g round ed rath er than 2 without degradation of performance, but pin 2 is suggested as iirst choice in the interest of consistency.

Signal Input Connector Wiring Signal Output The output signal for connection to line facilities is to b e fed from the male SIGNAL OUT connector til an XL type female connector on the outgoing cable. Use pins 2 and 3 for the signal output w ith pin 1 as ground. See figure 16. A balanced line may be f ed from 2 and 3, or an unbalanced line may be fed by ground ing either 2 or 3. In the interest of cons ist ency, it is suggested that 2 be emp l oyed as ground and 3 as th e signa l lead. 36 M23 RRM 2-69 r r r r r Two switches are provided on the rear panel of the electronics just above the SIGNAL OUT connector. The OUTPUT IMPEDANCE switch provides for selection of 150 or 600 ohms output line impedance and the TERMINA TION switch provides for proper terminating impedances for either 150 or 600 ohms, if needed. If the outgoing line is properly terminated elsewhere, set this switch to the OFF position. Note that the positions of these switches will affect the reading of the VU meter as much as 2 db. This meter is normally calibrated to read the proper levels in a +4 dbm 600-ohm line. It may be recaLibrated by adjusting resistors in the line amplifier board. A chart of values for the selectable resistors is given under the discussion of this board in the Functional Description. r r ~---------------GROUND r r LINE r r r r r r r ~------~-------GROUND BALANCED LINE UNBALANCED 1090 Figure 16. Signal Output Connector Wiring Remote Meter A remote VU meter may be connected to pins 1 and 4 of this connector. See figure 17. It is essential that it be "built out" with a resistor network identical to the one set up on the Line Amplifier Board for the local meter and as shown in figure 17. Select the values of Rl and R3 from table 10 for the proper line operating level. The remote meter will indicate the same signals, input or output, as the local VU. It will not give indications of bias and erase current. Power to illuminate lamps in the remote meter is available on pins 3 and 6. Maximum drain should be 150 rna at 28 volts.

The pilot tone to be recorded is app li ed at pin 1 with grounded return on 4. The r ep roduced pilot i s on 2 with grounded r etu rn on 5. See figure 18. This connecto r is also used to provide signal to an external monitor loudspeaker if desired. The speaker is to be connec t e d to pins 3 and 6, and will ope r at e at reasonab l e monitoring volume level when the VU is set up for +4 dbm lines. It wi ll b e 4 db louder when the VU is set for +8 dbm lines and so on. A simple attenuator may be install ed on the speaker to reduc e its voLume. Pho n e s Monitor earphones may be plugged into the PHONES jack on the front panel. High impedance phones are to be used. Neither side of the circuit is to be g round ed. The phones will monitor either the input or tape pLayback, the same as the VU meter, which is the signaL being fed to the output Line.

Internal adjustITlents to be ITlade with screwdriver or wrench are discussed in the AlignITlent and Adjustment section. r r L r L r TAPE TRANSPORT CONTROLS The normal operating controls are located in the lower right-hand corner of the transport. See figure 7. These five illuITlinated pushbuttons control all tape movement through a system of safety interlock relays that prevent malfunction because of improper operation. Any button can be pushed in any sequence, at any time, with complete safety to the tape and machine. PLAY Button This causes the transport to move the tape at normal forward or record speed under capstan speed control. The transport can be placed in PLA Y at any time from any tape mode. For recording, both the PLA Y and RECORD buttons must be pushed simultaneously when tape is either at standstill or in the normal forward, play mode. FORWARD Button Activates the high speed tape advance in the forward direction. The fast forward mode may be initiated without pressing the STOP button. In fast forward, the tape lifters are activated and the head shield opens. The tape lifters may be manually overriden to allow tape to be heard. When the STOP button is operated from this mode, dynamic braking is used to stop tape, then a slight holding torque is applied to maintain tape tension. NOTE Magnetically operated reed switches, operated from a direction sensitive vane under the takeup reel turntable, control the dynamic braking and electrical switching when the transport is taken out of FOR WARD or REWIND mode. This vane is a sensor to determine the direction the tape is traveling. The appropriate reed switch then activates relay control circuits which place the transport in either FAST, FORWARD, or REWIND, preliminary to the STOP mode, depending upon the original direction. M23 RRM 12-67 41 STOP Button This button stops all tape motion fr om any mode of operation. It also indicates when the transport is ready for operation. It is illuminat ed when the transport power is on and tape is thread ed in the tape path. Without tap e in the tape path, the unit w ill not operate and this button w ill not be lit. W hen the STOP button is activated while tape is in the high speed mode, dynamic braking is applied until the tape stops. Then, t he transp art goe s into the STO P mode and a light holding torque is appli ed by both motors to maintain tape t ension . REWIND Button Tap e may be put into high speed even from fast forward, without danger h e ads ope rat e during high speed r ewind may b e manually overridden if you want rewind from any other mode of operation, of tape breakage. Tape lifters on both and the headshield opens. The tape lift e rs to hear the tape. RECORD Button This button connects the r eco rding c ircuits to the record head. To operate, the but t on must be pushe d at the same time as the PLAY button is pushed. This must be done when tap e is either at s tand s till or running in PLA Y mode. Stopping the tape, or changing the tape mode of operation, automatically deactivates the record i ng circuits; and the RECORD and PLAY buttons must be pushe d again to r es um e r ecor ding. To complete the recording circuit, the recording amplifier switch on the applicable e lectroni c assemblies must be in RDY position. The remaining controls are mounted in the lower left-hand of the transport. POWER Switch AC power to t he en tir e record e r is controlled by this switch . NOT E The tape transport wi ll not be ene rgized and the STOP button will not light until tape is thr eade d into the tape pat h. Do not turn the power off when the transport is in a fast tape travel mode (REWIND or FORWARD). This could throw a tape loop because the dynami c braking will not operate. 42 M23 RRM 2-69 r r:.·; ' f· r r r A-B OUTPUT Transfer Switch This pair of pushbuttons provides for simultaneous transfer of the signal outputs of each electronics assembly from the input line to tape playback, or vice versa. The A button sets all channels to monitor the input signal. The B button transfers monitoring of all channels to the output signal. RUN OUT Switch NOTE r r r r r r r r Apparatus associated with this switch is not normally furnished. It must be specially ordered. This switch controls the actions of a photo sensor in the tape path. It can be set to automatically stop the tape, or to automatically rewind the tape. The switch circuits will also automatically start another tape machine. To activate the circuits, punch a 1/4 inch hole in the tape, or remove the oxide with solvent 3/8 inch above the lower edge of the tape at the point where one of the automatic operations is desired. When the hole passes the sensor, the tape will automatically stop, or rewind, depending upon the position of the switch. W hen the switch is in the center (NORMAL position), the automatic feature is inactive. When no hole is made in the tape, the unit will automatically shut off when the tape runs out. SPEED Sw itch The SPEED switch selects either of the two speeds at which the machine operates. These are normally 7 1/2 and 15 ips; however, other speed pairs are available. This switch should not be oper ated with the capstan motor running. Power must be off or tape not threaded. ~> fl.,.:.: .:.•.·• I f. BALANCE Switch :::·.·.!..·::·· r f This 3-position switch changes motor torque factors to compensate for reels of different weight and/or size. When both reels are identical, the switch remains in the middle, or BALANCED position. If the left reel is larger or heavier, the switch should be in the left position. If the right reel is larger or heavier, place the switch in the right position. r M23 RRM 2-69 43 TAPE TRANSPORT, TAPE HAND LING COMPONENTS The following tape components are in the capstan handling assembly area. See figure 19. Reversing Idler Tap e is th r eaded around this free - whee ling idler, whi ch he lps provide an extre me ly sho r t path of unsupport ed tape. Ridges in the idler provide for ai r passage during high-speed tape movement, so that the tape hugs t he idler. Editing Index The tri - co l ored bars and dots on top of the r eve rsing i dler are used for precision ed iting, as d esc ribed in the sec tion on editing. Head Assembly A ll h ea d stacks, e ras e , r eco rd a nd play, are mounted on a sing l e plug-in prec i sion p l ate whic h is mounted on the transport casting ben eat h this head cover . The trim plates must be r emoved in orde r to remov e the head assembly . Azimuth of record and playback h ea ds may be adjusted by removing the head cove r p l ate located betwe e n the capstan and reversing idler. Tape Lilters The tap e lifters automatically move tape away f r om heads during high-speed tape trav e l to r e duce h ead wear and cut c hatter. They are e l ect ri ca ll y interlocked with the playback head shield door so that the latter opens to make room for the tape when lifte r s move it away from heads. The tap e lift e r may be manually ove rridd e n by pressing the tap e lift e r and override lever. This r esto r es the tape against the h ead so that it may be h eard. Head Shield Door The head shie ld door provid e s for hum r eduction and automatica ll y drops away from h ead during high-sp eed tap e trave l and w h eneve r tap e is l ifted from tape path. This allows easy r emoval of tap e for edit in g, e tc. Capstan The differential capstan is the basis of th e patented I soloop system for transpo r ting tap e with extremely l ow flutter and wow .

Tape Drive Components M23 RRM 2-69 45 Capstan Idler (Incoming) This idler is designed to clamp the tape to the smaller diameter parts of the caps t an. The capsta n the r eby unwinds tape from the supply reel and fe e ds it into the l oop . In starting, this idler moves in slowly after initial contact so as to gently accelerate the tape to running speed.

The 7-1 /2-ips playback alignnlent is done in exactly the same manner except that the initial 700 Hz tone and the frequency run are at 10 VU below zero VU. They are followed by 700 Hz at zero VU and this should first be observed, as outlined under precedi~g step 6. Then rewind the tape to the first 700 Hz band, set the METER switch to SIGNAL, press the B OUTPUT transfer button and adjust the REPRO. LEVEL control to indicate -5 VU. The REPRO. LEVEL control is now set 5 VU higher than normal CAL. level, but it permits more accurate readings. Then check for ±I VU response 12, 000 to 50 cycles and ±2 VU 15, 000 to 30 cps, as outlined in steps 9 and 10. Adjusting HF EO SLOW and LF EO SLOW rather than HF EO FAST and LF EO FAST. These are automatically switched in when the tape speed is changed. The head azimuth adjustment and GAIN CAL adjustment made at 15 ips should not be disturbed unless 7-1/2 ips is to be considered the speed of primary usage. r M23 RRM 2-69 73 NAB Record Alignment The a li gnment procedur e to follow shou ld be carried out, using a length of tap e from the supply to be us ed for subsequent recording, whenever possible. The 3M Brand Professional Audio Recorder is factory aligned to use 3M types 201, 202 and 203 tap e . It is essential that the preceding playback alignm en t be checked before re co rd a li gnment. 15 IPS Tape Speed Alignment 74 I. Set REC. SELECT switch to RDY., the METER switch to SIGNAL and pr ess the A transfer button. The RECORD LEVEL controL need not be adjusted from its normal operating position if it has been Lo cked in place. The L I NEARIZER switch on the H and NAB Record Board in slot 4 shouLd be in the OFF position. Connect an audio signal gene ra to r to the rec o rd er inpu t (JI 0 1). 2. Set the audio signal gene rator to 1000 Hz and raise the LeveL until the VU meter indicat es 0 VU. 3. Check to be sure that meter continues to indicate 0 VU as the osc illator fr e quency is changed between 30 Hz and 15,000 Hz. If there is more than ±1/2 VU deviation in these indications, the reasons must be discove red beforE: continuing with the checkout. Possible r easons may be unstable oscillator out put versus frequency, improper termination, shunting capacitanc e on the input Line, or capacitive feed (one lead open between the osci llator or r eco rde r) . 4. Listen with a monitor speaker or earphones to be sure no strong noise or hum component is picked up at the input terminaLs in addition to the oscil la tor tone. 5. Start the record er in RECORD mode. Turn the METER switch to CAL. 6. Adjust the BIAS AMP contro l on the Bias and Erase AmpLifier Board in slot 1 to give a ma ximum indication on the VU meter for the 1000 Hz signal. The maximum shou ld occur at zero VU. If the meter indicates other than 0, adju st the input signaL leveL for a 0 indication.

Reset the oscillator to 15,000 Hz an d again ca r efully adjust the r ecord head azimuth for maximum. Using a simila r method as in step 8 of the NAB Playback Alignment, adjust the r eco rd head azim uth sc re w (figure 27) for less than 90 degrees ph ase e rror between any two tracks. M23 RRM 2-69 [ r r r r r r r r r r r r 8. Make a frequency run from 15, 000 to 30 Hz and observe the VU meter. If it lies within ±1 VU from 40 to 15, 000 Hz, and ±2 VU at 30 Hz, the performance may be considered satisfactory. 9. If the frequency response is not within acceptable limits, adjust the HF EQ FAST control on the H and NAB Record Board in slot 4 to bring response within limits. 7-1/2 IPS Tape Speed Alignment Having checked the playback circuit and adjusted it for flat response as outlined under NAB Playback Alignment, 7-1/2 inch speed, leave the REPRO LEVEL control set in the position established under that procedure which resulted in the standard tape signals recorded at -10 VU showing -5 VU on the meter. Then proceed as follows: 1. Perform steps 1, 2, and 3 of the procedure outlined under NAB Record Alignment, 15 ips Tape Speed Alignment. 2. Reduce the input signal level so that the meter indicates approximately -10 VUe 3. Listen with speaker or phones to be sure there is no strong noise or hum component picked up at input terminals in addition to the oscillator tone. 4. Put the recorder into record mode. Press the B OUTPUT transfer button. The meter should indicate approximately -5 VUe 5. Adjust the BIAS control on the Bias and Erase Board in slot 1 for maximum VU indication at 500 Hz. Readjust input signal level if nece s sary to get -5 VU. 6. Set the oscillator to 5000 Hz. Adjust the azimuth of the record head stack to give a maximum indication on the VU meter. Reset the osciLlator to 15, 000 Hz and carefully adjust azimuth for maximum indication. If primary speed of interest is 15 ips, skip this step. 7. Make a frequency run over the range of 30 to 15, 000 cycles and observe the VU meter. If it indicates within ±1 VU from 40 to 12, 000 Hz, and ±2 VU from 30 to 15, 000 Hz, the performance may be considered satisfactory. 8. If the frequency response is not within acceptable limits, adjust the HF EQ SLOW control on the H and NAB Record Board in slot 4 to bring response within limits. r l r r M23 RRM 2-69 75 9. Return the signal generator to 500 Hz. Adjust the REPRO. LEVEL control to obtain approximately -10 VU indication. Turn the METER switch to CAL. Raise the input l eve l to obtain a VU indication on mete r. 10. Press the A OUTPUT transfer button and turn the METER switch to SIGNAL. The meter should indicate a VU . If it does not, adjust the RECORD MON. CAL. control on the H and NAB Record Board, slot 4, until a zero indi cat ion is obtained. If there is a discrepancy in this adjust=ent between the 7-1/2 and 15 IPS setting, adjust it for the speed mo'st important to the application. NOTE The above procedu re permits frequency response measurements to be made at a signal level 10 VU below the zero reference level. This is essential with low speed tapes (7-1/2 ips or slower) because of the h eavy r ecordi ng preemphasis used for higher frequencies. Dynamic Range Adjustment (NAB) 76 1. Connect the signal generator to a calibrated attenuator box and terminate the output of the box. Feed this output to the input of the channel und e r test. C onnect a distortion analyzer and a vtvm to the output terminals. Use a reel of tape of the type for which the recorder has been aligned. The tape speed should be 15 ips . 2. Before beginning noise measurements, it is absolutely essential to degauss and clean all heads very carefully. Turn off the main recorder power switch during degaussing. Connect a high gain power amplifier and loudspeaker to the output terminals of the r eco rder. Short circuit the input terminals. The METER switch should be set to ERASE with the B OUTPUT lamp lit. 3. Advance the monitor gain so that the tape noise is heard loudly. 4. Remove the 3N card. Press the RECORD button.

Set the oscillator to 1000 Hz and use a decade attenuator to insert a 19 db loss. 8. Set the LINEARIZER ,switch on the H and NAB Record Board in sLot 4 to OFF. 9. Put the recorder into the RECORD mode. The B OUTPUT Lamp must be Lit. Readjust the input Leve L to obtain 0 VU on the meter. 10. Measure distortion on the wave analyzer. It should be just under 1 % total harmonic distortion. 11. Rewind some of the tape and pLay it back. Observe the distortion. If it is lower, it means that high-frequency bias current is leaking into the distortion analyzer during recording and a Ll mea surements wi Ll have to be made through a low-pass filter or during playback only. 12. Return to recording the 1000 Hz signal at 0 VUe Remove 6 db from the calibrated attenuator. The distortion meter should indicate just under 3% total harmonic distortion. Observe the vtvm indication. 13. Disc onnect the oscillator from the input to the attenuator and record some tape with this input signal removed, ·(approximately 30 seconds of tape). 14. Play back the tape so recorded, and read the vtvm. The difference in readings between tape recorded in steps 12 and 13 represents the signal-to-noise ratio measured from the 3% distortion point without the linearization circuit in operation. Place the LINEARIZER switch to ON. NOTE r r r Noise figures stated in the system specifications are obtained by the use of bandpass filters. Such filters exclude all noise outside the stated passband. Miscellaneous Adiustments and Circuit Arrangements When the METER switch is set to the BIAS position during recording, the VU meter indicates a steady leveL, determined by the amplitude of bias current in the rr r M23 RRM 2-69 77 record head. When this current is optimized, the meter indication can be adjusted to a conve nient reference by means of the BIAS MON. CAL. control on the Bias and Erase Board in slot I. This provides a ready check of bias at any time. When the METER switch is set to the ERASE position during recording, a similar check is provided for the magnitude of the erase current. This may be calibrated to read any convenient level by means of the ERASE MON. CAL. control on the NAB Erase Coupler Board in slot 3. The recorder is normally set up to supply a 600-ohm line at the +4 dbm level. The o utput impedance switch can be set to select either 600 ohms or 150 ohms, and the t e rmination switch can be set to 600, 150, or open position. If it is desired to change the working line level from +4 dbm to some other level, it is necessary to change certain resistors on the Line Am plifier Board in slot 6. A chart of values is shown in the circuit description for this board. The use of the PILOT connector and the REMOTE METER connector are fully described under circuit descriptions. The linearizer adjustment should be undertaken in accordance with the following outline. If the user feels the adjustment has been misset it may be disconnected by setting the LINEARIZER switch to OFF until properly aligned. As delivered, the machine is adjusted for use with Scotch brand low-noise tape t ypes 201, 202, and 203. Under normal conditions no adjustments should be necessary. The switch should always be in the ON position except when distortion measurements are being made. If the machine is to use a different type of tape, the LIN A DJ. control may requir e trimming. This is best don e with aid of a wave analyzer. Adjustment is done as follows: 78 I. Set the METER switch to CAL position. 2. Make the frequency response and dynamic range adjustments and measurements outlined above for the type of tape used 3. Set LINEARIZER switch to OFF position. 4. Raise record level to give 3% third harmonic distortion. 5. Set LINEARI ZE R switch to the ON position. 6. Adjust LIN ADJ. control for minimum distortion. 7. Adjust input level to again achieve 3% third-harmonic distortion. 8. Repeat steps 5, 6, and 7 until no change in record level is necessary. M23 RRM 2-69 r r r r r r r r r r r r r 9. Adjust record level to provide zero VU playback level. 10. Press the A OUTPUT button and set METER switch to SIGNAL. Meter indication should remain at 0 VU. If it is higher or lower, adjust RECORD MON. CAL. control to obtain zero indication. If it should be necessary to adjust the linearizer without the aid of a wave analyzer, a satisfactory approximation to the ideal adjustment c'an be made with a vtvm as follows: 1. Set METER switch to the CAL. position and LINEARIZER switch to OFF. 2. Using a standard alignment tape establish a reference level on the vtvm. 3. Using the desired tape type adjust the record level to obtain a signal 6 VU above 0 VUe 4. Set LINEARIZER switch to ON. Output level should rise 0.8 VU if the linearizer is properly adjusted. If not, adjust the LIN ADJ. control to achieve the difference. 5. Set the LINEARIZER switch to OFF. If output level is changed from +6 VU, readjust record level to again obtain +6 VU. 6. Repeat steps 4 and 5 until the 0.8 db difference is attained upon operation of LINEARIZER switch and the indicated operating level is +6 VU with the switch in the OFF position. 7. Reset RECORD MON. CAL. control if necessary as outlined above. Series 400 recorders equipped to provide overdub recording capability should be set up in accordance with the following procedure: NOTE r r r r r r For maximum flexibility, it is desirable to employ a No.7 board for normal reproduction, and a permanently installed No.7 /9 board in slot 9 to provide overdub facilities. When furnished in this manner the recorder is considered having permanent overdub capability. 1. Place a No.7 /9 board in slot 9. Position the REC. SELECT switch to the O. DUB position. M23 RRM 2-69 79 2. Set the METER switch to CAL. Press the PLAY button. Adjust the GAI N CAL control on the 7/9 card for zero VU on the meter when the 700 Hz signal is playing from the standard alignment tape. Press the STOP button. DYNATRACK ELECTRONIC ALIGNMENT The Dynatrack system is designed for operation only at 15 ips. Refer to pages I to 4 for a description of the Dynatrack system. In a normal NAB system, one track is assigned to each electronics assembly unit and provides for recording and playback of a separate signal input and output channel. In the Dynatrack system, two tracks are emplcSyed per signal channel. The heads will have been properly connected to the electronics assemblies of a factory assembled Dynatrack system but for s y stems delivered for NAB operation, observe the following conversion procedure . It is assumed that the Dynatrack kit has been installed in accordance with the Dynatrack installation procedure which accoITlpanies the kit. I. Reconnect the head cables to the electronic assemblies in accordance with the assignITlent shown in table 3. 2. Observe figure 26. Be sure the Dynatrack boards are installed as shown for electronic asseITlblies to be employed for this operation. Those not so converted should retain the NAB arrangement, also shown in figure 26. Figure 26 is reproduced on the inside of the electronics asseITlbly cover door. 3. Set the REC. SELECT switch on all nonconverted NAB electronic assemblies to SAFE and the A-B OUTPUT selector on A. Deactivate the automatic transfer by setting the AUTO A-B switch on each no. 6 board in the NAB asseITlblies to OFF. 4. Put the NAB standard alignITlent tape for 15 ips on the transport. 5. Set the REC. SELECT switch to SAFE and the METER switch to CAL. Set the MODE switch on the 8D board to the HI position. The pilot laITlp should go out. NOTE Be certain output iITlpedance and terITlination switches on the rear of electronics ITlodule are in proper position for the connected outgoing line. 6. 80 Put the machine in the PLAY ITlode at 15 ips. When the reference tone of 700 Hz appears, the ITl e ter should indicate 0 VU. If it does within 1/4 db, proceed to st e p 7. If not, adjust the GAIN CAL. control on the board in slot 7 to obtain this indication. M23 RRM 2-69 r L L L l L 7. Play the 15, 000 Hz azimuth check tone and adjust the playback head azimuth (figure 27) for peak output as indicated on the VU meter. S. Play the 10, 000 Hz test tone, and adjust the HF EO FAST control on board 7 to obtain a VU on the meter. Play through the tape, and adjust the LF EO FAST control on board 7 so that all frequencies between 50 and 10, 000 Hz fall within ±1 VU of the 700 Hz reference level. 15, 000 Hz shall be no more than +2. 5 VU from the 700 Hz reference. 9. After making necessary equalizer adjustments, rewind and replay the standard tape to be certain that the response at all frequencies is within the limits specified in step S. 10. Rewind the tape. 11. Place the MODE SWITCH on the SD board -in the LO position. The pilot lamp should light. Set the equalizer switch behind the extractor handle to the lower OFF position. (This switch is not shown in figure 26. ) 12. Put the machine in the PLA Y mode. When the reference tone of 700 Hz appears, the meter should indicate a VUe If it does, within 1/4 VU, proceed to step 13. If it does not, adjust the GAIN control on board SD until it is within limits. 13. Play the 10, 000 Hz test tone, and adjust the HF EO control on board SD to obtain a VU on the meter. Play through the tape, and adjust the LF EO control on board SD so that all frequencie s between 50 and 10, 000 Hz fall within ±1 VU of the 700 Hz reference level. 15, 000 Hz shall be no more than +2. 5 VU from the 700 Hz reference. 14. Set the MODE SWITCH on board SD to the AUTO position (mid position). Rewind the alignment tape to permit playing the 5 kHz tone. Adjust the TRIG control on card SD so that the neon lamp is on the verge of extinction in the pre sence of the tone as indicated by slight flickering. 15. Set the equalizer switch behind the extractor handle on card SD to the upper ON position. (This switch is not shown in figure 26. ) L L r r r r r r Dynatrack Recorcf Alignment This alignment procedure should be carried out, using a length of tape from the supply to be used for subsequent recording. The 3M Brand Professional Recorder is factory aligned to use 3M types 201, 202, and 203 tape. The procedure accomplishes the following. It checks the H track for alignment to NAB standards, adjusts the level and frequency response on the L track, and compares the two tracks for identity of level and frequency response. M23 RRM 2-69 81 NOTE Do not upset any of the playback adjustments for either the L or H track which we re established above. H Track NAB Alignment 82 1. Set REC. SELECT switch to RDY and the METER switch to SIGNAL. Press the A OUTPUT transfer button. Place the LINEARIZER switches on the L record board (3D) and on the H record board (4) to the OFF position. Place the MODE SWITCH on the L preamplifier and switch board (8D) in the HI position. 2. The RECORD LEVEL cont rol need not be adjusted from its normal operating position if it has been locked in place. 3. Connect an audio oscillator to the SIGNAL IN connector and set the the oscillator frequency to 400 Hz. Adjust the oscillator output level until the VU meter reads 0 VU. 4. Check that the m e t e r continues to indicate 0 VU if the oscillator frequency is varied from 30 to 15,000 Hz. If there is more than 1 /2 VU deviation in these indications, the reason must be determined befo re continuing. Set the os cillator to 1000 Hz. 5. Listen with a monitor speak e r or earphones to be sure t hat there is no strong noise or hum component picked up at the input terminals in addition to the oscillator tone. 6. Put the recorder in the RECORD mode. Turn METER switch to CAL. The mete r should indicate 0 VU. 7. Adjust BIAS AMP. control on board 1 to give a maximum indication on the VU meter for the 1000 Hz tone being recorded on the H track. The maximum should occur at 0 VU. If the meter indicates other than 0, adjust the oscillator output level until 0 indication is obtained. Then with the A OUTPUT lamp lit, turn the METER switch to the SIGNAL position, and adjust the RECORD MON. CAL contro l on board 4 until it again indicates zero. Return the METER switch to the CAL position. 8. Set the osciUatpr to 7000 Hz. Adjust the azimuth of the record head stack to give a maximum indication on the VU meter. Set the oscillator to 15,000 Hz and carefully trim the azimuth adjustment for maxirnwn. M23 RRM 2-69 r r r r r 9. Make a frequency run from 15,000 to 30 Hz while observing the VU meter. If it is within ±1 VU from 40 to 15,000 Hz and ±2 VU at 30 Hz, the performance may be considered satisfactory. 10. If the frequency response falls outside these limits, adjust the HF EO FAST control on board 4 to bring the response within limits. This completes frequency and amplitude alignment of the H track. L Track Alignment Align the L track for frequency response as follows: r r r r r r r ·,'i", 1. Set the MODE switch on the 8D board to the LO position. Turn the METER switch to SIGNAL. 2. Set the oscillator to 250 Hz and reduce the input signal level by approximately 20 db below the 0 VU level by adjusting the oscillator output control or by using a step attenuator. 3. Put the machine in RECORD mode. Transfer the OUTPUT to B. 4. Raise the signal level by the REPRO. LEVEL control until a convenient playback level is indicated. Lock the control in this position. If the reading is still several db below 0 VU, an external VTVM fed from the output of the channel may be useful for making measurements. 5. Set the oscillator to 1000 Hz. Adjust the BIAS ADJ. control on the 3D board to obtain a maximum reading on the meter. Should this result in a higher meter indication, reset' the oscillator output to again obtain the convenient reference as in step 4. 6. Make a frequency run from 15,000 to 30 Hz while observing the meter. If the response is within ±1 VU (db) from 40 to 15,000 Hz and ±2 VU (db) at 30 Hz, the performance may be considered satisfactory. 7. If the frequency re sponse is not within acceptable limits at the high frequency end of the spectrum, adjust the BIAS ADJ. control on the 3D hoard slightly . I, r f i'," .L r "r, ( f !,;,' i Combined H-L Dynatrack Performance To adjust the relative amplitudes of the signals in the two tracks comprIsIng a dynatrack channel, it must be borne in mind at this point that the playback levels of both tracks have been properly set using a standard alignment tape and that the recording level in the H or NAB track has been properly established. This leaves only the adjustment of the L track recording level to be determined. M23 RRM 2-69 83 1. Set the MODE SWIT CH on the 8D board to HI, the METER switch to the SIGNAL position, and pres s the OUTPUT transfer B button. 2. Record 700 Hz at a level that will indicate zero VU on playback by adjusting the output amplitude of the oscillator. 3. Set the MODE SWITCH on the 8D board from HI to La. The meter indication should not change. If it does, adjust the GAIN control on the 3D board until meter indicates zero. 4. The LINEARIZER on board 3D will probably not require adjustment. It may be check e d and adjusted as outlined for the NAB track. In this case, however , us e 500 Hz for the alignment procedure. 5. Unlock the REPRO. LEVEL control knob and return it to approximately the normal operating position. Return the MODE SWITCH to the A UTa position. 6. Check the operation of the trigger circuit as indicated by the neon lamp on board 8D. Whi l e in the record mode, feed various frequencies into th e channel. Raise and lower the level slowly by adjusting the oscillator output in order to cause the lamp to turn off and on. At 1000 Hz, this should occur at about 0 VU and at low er lev els as the frequency is raised until a level of about -15 VU causes extinction of the lamp at 15 ,000 Hz. There is no requirement for lamp extinction at any frequency lowe r than 400 Hz. 7. Listen carefull y in a high l evel monitoring system for clicks and pops when making the t es ts in paragraph 6 above. They should be almost comp l etely i naudib l e. 8.

Readjust the oscillator gain control (not the attenuator) to obtain zero VU indication on the meter. 10. Measure the distortion on the wave analyzer. It should be just under 1%. 11. Rewind some tape and play it back. If there is a significant ment in the di stortion reading it means that high-frequency is leaking into the distortion analyzer dU'ring recording. In stances measurements must be made through a proper low or only on playback. 12. Change the oscillator frequency to 1000 Hz. Check by recording the signal to be certain that the VU meter still indicates zero level. 13. Remove 6 db of attenuation from the calibrated attenuator. The VU meter will be off scale. Readjust the distortion meter to ana lyze 1000 Hz. It should show 3% total harmonic distortion. 14. Observe the indication on the vtvm which is fed through the ASA weighting network from the output of the recorder. 15. Disconnect the oscillator by unplugging it from the input to the attenuator, while the recorder is still in the record mode and short circuit the input terminals. Continue to record for about 30 seconds. 16. Rewind the tape far enough so that the 3% level tone will be first reproduced, followed by tape recorded with no input signa 1. Set the MODE SWITCH to AUTO. 17. Play back the tape. During the tone the pilot lamp on the 8D board in slot 8 should be out. Observe the vtvm reading. When the tone runs out, the pilot lamp should light. Again read the vtvm. The difference in readings is the weighted signal-to-noise figure. It should be 80 db. This reading may be attained only after several rotations of the supply reel since a ce rtain amount of printing from the high leve 1 (+6 VU) signal to the quiet tape is inevitable in the first few layers. 18.

Heads are mounted on a plate which provides azimuth adjustment of both record and playback head stacks. Erase heads are fixed in position. The plate carries a connector which mates with another permanently mounted in the tr~nsport. The transport connector has leads attached to it which connect to the electronic assemblies. ALL of these connectors are physically interchangeable. It is imperative that the number and letter coding be observed. ~ L To change a head assembly, first remove the head cover trim, then the transport cover plate, and then the reversing idler (held in place by one screw under the main casting). See figure 23. Next remove the two metal trim plates (one on either side of the capstan and idler). Remove the screws that hold the head mounting plate in place. Insert two screws into the tapped holes at either end of the connector plug. As these are screwed down, they will jack up the plate and gently separate the connectors. An alternate head assembly may be installed by foLLowing the reverse procedure. Head stacks of various physical heights may be interchanged. On machines with one-half inch capstan height any heads for up to 1/2 inch tape width may be mounted in place. For machines with one-inch capstan height, any heads for up to 1 inch width may be mounted. TAPE GUIDES r r.·· L The function of the tape guides is to cause the tape to be fed into the Isoloop without lateral shifting, so that the recorded pattern remains within the NAB margins, and to cause the tape to wind evenly onto the reels so that each turn Lies on top of the other and does not contact either reel flange. The prima ry tape path reference is the lower flange of the ingoing guide which guides the tape into the Isoloop. When head assemblies are changed to accomodate a different tape width, it is necessary to change the tape guides. These may be removed by unscrewing them from the main casting. Replace with guides having the appropriate height. Remember the guides having the narrower opening (a few thousandths of an inch) go on the incoming (supply) side of the capstan. The wide ones go on the takeup side. This guide surface is set at a fixed distance from the capstan assembly machined surface, on which the heads are mounted. The desired guiding is one that feeds tape into the Isoloop with the edges touching, but not binding on the flanges of the incoming guides. The outgoing tape guides are wider. Their flanges do not guide the tape in the normal running mode. M23 RRM 2-69 87 Tape guides will not normally require adjustment unless the machine is converted for a wider, or narrower tape. New guides, heads, and reel hubs are finished as part of a conversion kit. The replacement guides are installed by their cent e r screws. Proper flange height is established by holding machining and plating tole ranc e s, and no shimming or threaded adjustment is required. To assure that tape guiding is satisfactory and that no damage or misadjustmen t has occurred, the following examination can be made. I. The lower edge of the tape (inner edge of the tape if the transport is mounted vertically) registers lightly on the lower (inner) flange of the incoming guide nearest the capstan. The tape does not move up or down on the reversing idler as the tape direction shifts from forward to rewind. 2. The wear pattern on the heads and guides is straight-sided. (Not keystoned, which would indicate uneven tension across the tape. ) There must be no evidence of a I /4-jnch groove on I /2-inch guides and heads, or a 1/2-inch groove in I-inch heads, etc. REEL HUBS The function of the reel tables and holddown hubs is to hold the tape reels in p lane of the tape path, so that tape is fed out and spooled without scraping on eithe r reel flange. The hub is held in place by a shaft collar on the reel motor shaft. See figure 29. Position of the collar is secured by two setscrews. After a reel is installed the finned, spring-loaded top of the knob may be turned a few degrees clockwise, which will lift the three small bevelled projections up out of the reel keyway slots to rest on the top of the reel, locking it firmly to the reel tabl e . Reel table height should not require readjustment unless a reel motor is replaced. A small I /4-inch center reel table and hub is available to accommodate hom e -recorder type reels. To install this reel table, the large coinslot center screw in the NAB reel hub is loosened, the top lifted off, and three small Phillips screws removed. The I /4-inch table and hub are then installed, using the three flat-head screws. The 1/4-inch reels are held in place by turning the top part of the spindle so that the bevelled keys rest on top of the reel, as in the NAB hub. 88 M23 RRM 2-69 r r r ~I 0.488 ±C.0l INCH REEL MOTOR REEL TABLE r r r r r r r r 1179 Figure 29.

Adjustments are presented in the Alignment and Adjustment section. This section contains special notes concerning maintenance and troubleshooting. GENERAL PRECAUTIONS The following paragraphs contain some general precautions which should be observed when performing maintenance on the recorder. 1. Do not strike the reversing idler. It is delicate and located in a vulnerable position at the front of the mechanism. If damaged, flutter will be excessively high. 2. Exercise great care in installing head mounting plates. They can be screwed into place with a head lead pinched between the mounting plate and the transport casting, thus breaking wire insulation or cutting a head lead. Be certain no leads will get in the way before installation. 3. Exercise great care in removing and replacing the mu metal cover over the playback head stack. The slot at the rear of the cover can slice head lead insulation, thereby grounding head leads or actually cutting through them. Be certain that this cover is fully seated so that the lower lip will not scrape on tape as it passes by. Otherwise tape edge may be cut and bad tracking over the heads may result. 4. Do not go from REC. to SAFE when the recorder is operating in the RECORD mode. First stop the transport. This will prevent a thump from being recorded in the tape and magnetization of tht~ record head. 5. Do not remove any of the electronic s cards when the power is on. It requires only a few seconds to turn off the power, remove a card, restore power and be ready to operate. Otherwise it is possible to magnetize a head or damage a mete r. 6. It is particularly important when moving a 7/9 board from position 9 to position 7 to first turn off the power, then wait about 20 seconds before removing the board and reinstalling it. 7. Be certain to remove the power cord from the transport when moving the recorder. This is to ensure that the capstan motor lockout device will prevent the motor spud from pounding the rubber tire on the flywheel. r r r r r r r r r M23 RRM 2-69 91 8. Be ce r ta i n no head cables on t he powe r boards touch the rubbe r tire on the flywheel at any time, eithe r when installed or in shipment. 9. The individ u al electronics mod ul e powe r s upplies a r e mounted behi n d the mete r. They a r e accessib le by pu lling the meter forward. Pull the meter by the fing e rs app l ying force to the mete r case below the transpa r ent window, not above, since this may resu l t in a cracked case. 10. Never car r y an e lectronics assemb l y face downwa r d as the powe r supp l y module may fa ll out, b r eaking the meter. 1 1. Do not a ll ow ree l s or flanges to scrape on the painted surface of t he trim p late as this will ma r k it badly. Scraping can be caused on ly by bent ree l s o r flanges which, if they cannot be repai r ed shou l d be dis carded . TRO UB LESHOOTING Failu r e of the recorder to op e rate p r ope rl y may be caused by a malfunction in th e recorder, o r b y external caus e s. Before trouble s hooting the recorder, verify that the power and signa l connections a r e correct, and that a ll of the operational contr o ls are prope rl y set.

M23 RRM 2-69 [ PRINCIPLES OF OPERATION r r r r r r r r r r r r r r r INTRODUCTION The 3M Brand Professional Audio Tape Recorder is an advanced audio recording instrument that incorporates the best techniques available at the present state of the art. A tape recorder consists basically of a tape transport (deck) and record and reproduce (play) electronics. The signal to be recorded is amplified and applied to a magnetic record head, which impresses a magnetic pattern in the oxide coating of the magnetic recording tape in accordance with the variation of the input signal. During reproduction (play) the variations in magnetic flux that were impressed on the tape during recording, are sensed by a reproduce head, amplified, and applied to the recorder output. In order to record a nd reproduce with a mInlmum of distortion, a highfrequency bias is mixed with the input signal at the record head so that recording takes place in the portion of the magnetization curve that is essentiaLLy Linear. The signal recovered by the reproduce head must also be equalized by circuits that compensate for the response characteristics of the reproduce- head at low and high frequencies. The high-frequency signal that is used for bias is also used to erase signals that may have previously been recorded on the tape. The erase signal is applied to a separate erase head, which is similar to the record head but applies the highfrequency signal at a much higher leveL. The signal applied to the erase head drives the magnetic material of the tape to complete magnetic saturation to obliterate any signal, or noise that may have been previously recorded on the tape. The patented Isoloop tape drive maintains differential tension within the loop of tape passing over the heads and ensures that the tape remains in close contact with the heads during tape traveL. This ensures that the magnetic flux impressed by the record head penetrates the oxide material uniformly and eliminates variations in amplitude that can result if the close head-to-tape contact is not maintained. Similar amplitude variations can take place if the tape is not maintained in close contact with the play head. Tape Drive Components (See Figure 30) Components of the tape drive system consist of a capstan drive motor, two reel drive motors, and control relays tha t determine the mode of operation. When in pLay and record modes, the tape is moved through the Isoloop by the capstan. The reel drive motors maintain constant tension on the tape as it enters and Leaves the loop. ·When in fast-forward or rewind, tension is released within the Isoloop and the reel drive motors move the tape through the loop independently of the M23 RRM 2.-69 101 TAKEUP REEL SUPPLY REEL INCOMING OUTGOING CAPSTAN CAPSTAN IDLER IDLER BIAS AND ERASE OSCILLATOR Iii ]1------1 AI""'''"....... >---~ OUTPUT SIGNAL INPUT SIGNAL RECORD HEAD PLAYBACK HEAD REVERSING IDLER Figure 30 . 102 Tape Recorder, Block Diagram M23 RRM 12-67 liB) [ r r r r r r r r r r r r r r r capstan. Before entering and after leaving the Isoloop, the tape passes over stationary guides to ensure that is properly aligned with the magnetic heads. When the transport is in the play and record modes, solenoids press the capstan idlers against the tape, clamping it to the capstan to prevent it from slipping. The tape is moved past the income idler and capstan, past the erase and record heads, and around the reversing idler. From the reversing idler, it passes the play head, and the outgoing idler and capstan. During fast-forward and rewind, solenoid-actuated tape lifters hold the tape away from the tape so that signals on the tape will not be played back, which would cause an annoying squeal. The tape lifters are inactive in play, record, and stop modes. The play head is enclosed in a magnetic shield to avoid pickup of noise from surrounding equipment and bias-frequency energy radiated by the erase and record heads. A solenoid-actuated cover is positioned over the tape as it passes the play head and serves to complete the shielding of the head. During fast-forward, rewind, and stop, the hinged cover is moved away from the head to allow the tape to be lifted by the tape lifters and allow easy threading of the tape. The cover is closed during play and record. TAPE TRANSPORT CIRCUIT DESCRIPTIONS The following circuit de scriptions relate to figure 31 which must be used to follow the discussions. In the schematic, connector terminals are shown as small rectangles with the connector and terminal numbers inserted. Power Circuits A standard, three-wire power cable is provided, which must be connected at J 1. The third, or ground, lead must be connected to a good earth ground; otherwise the recorder will not meet dynamic range specifications in regards to hum, harmonic buzz, or radio-frequency fields. The power is normally 60 cycles, 105 to 125 volts, but 50 cycle models for the same voltage range are available and entail only a change of capstan motor characteristics. The schematic otherwise remains unchanged. For 220 volt operation an external line transformer must be used. The POWER switch, 56, when operated, closes both sides of the input line activating a number of circuits. These are as follows: 1. Bridge rectifier CR46 through CR49 charges capacitor C6S through R60 approximately 165 volts in the absence of a load. This voltage is applied through J7-2 and J9-1 to the fields of the takeup and rewind motors. Field returns are through J7-1, and J9-2 through J6-4, and K 1 contacts 6 and 10. Relay K 1 operates as soon as power is turned on unless the transport has been previously threaded with tape. M23 RRM 2-69 103 104 2. Power is supp l ied from terminals J4-11 and J4 - 12 to the various e l ectronics modu les through an interconnecting cab l e . 3. Power is supp lied to step-down transformer T60 from termina l s TB3-2 and TB3-1. The low - voltage secondary feeds terminals J5 - 2 and J5-3. A ful l- wave bridge on the board, consisting of CR37 and through CR40 supplies charging current through terminals J5-5 and J5-1 to C66 and regulator transistor 060. Zener Diode CR50 is supplied from R14 and establishes a voltage reference of 27 volts, applied through R15 to the base of amplifier transistor 01. The collector of 01 is directly coupled to the base of 060 and the output col lector potential of 060 estab lishes the emitter voltage of 01. The two transistors thus act to r egulate the bus potential (approximately 26.5 volts). When power is applied the bus potential lights POWER indicator D56, and the tape senSing lamp D58. If fail-safe brakes are furnished, L6 operates to re lease them. As the solenoid approaches the end of its stroke, 515 is opened to reduce current in L6 by insertion of R73. Without tape on t he machine, light from D58 fa ll s on photo sensor V60. The base of 061 is thereby held near ground potential. The collector at 061 is then at a re lative l y high potentia l causing 062 to increase conduction. Cur rent flows through 062 to relay K 1 through J6-7 to operate relay K 1. Through Kl contacts 11 and 7, voltage is applied through J6 - 9 to J3 - N, to light an indicator lamp on the Remote Control; if used, to show that the machine is on but inoperative due to the absence of threaded tape . The playback head shield cover door is caused to open through CR - 25, J6 - 14, and TBl-l with a return path through TBl - 2. Also at this time, K 1 contacts 12 and 4, and 11 and 3 are open and the 27 volt bus can perform no further function. Because of this, the machine may not be put into any mode of operation until tape is threaded on the machine . 4. A path is p r epared through J5-F to J5-D and Pll-2J to furnish power to the capstan motor, but this is kept open by K 1 contacts 1 and 9 when tape is not threaded. The capstan motor is energized through J8-7 and 58 to either J3 - 8 or J8 - 4 . The quadrature winding of the motor is supplied through C64 and R63 and through 58 to either J8-5 or J8 - 6. Motor return l eads, depending on the speed selected by 58, are through J8-1 and J8 - 2, or J8-1 and J8 - 3 back to switch 56 through PII-Jl. When power is supplied to the capstan motor it is a lso supplied to bridge rectifier CR42 through CR45. The dc output of the bridge is applied through J5-J, R68, and TB2-3 to a so lenoid, which pu l ls the motor pulley phYSica lly into contact with the capstan flywhee l tire. Return path of the solenoid is through TB2-2 and J5-7. Filter capacitor C68 prev!,nts induction of hum from the solenoid into the playback heads. M23 RRM 2-69 r r 5. Power is applied to J3-c and J3-d for application at the remote control position, if required. 6. The fan is normally connected across TBI-4 and TBl-6 where it is operated only when the capstan motor is running. By removing the fan lead on TBl-4 and connecting it to TBl-5, the fan will run whenever the power switch is on. Threaded Tape Condition When a reel of tape is placed on the supply hub, the free end is passed through the incoming side of the Isoloop, past the capstan and record head, and around the reversing idler, then between the outgoing side of the capstan and its idler. When the tape is dropped into position at this point, light is cut off from V60 causing relay Kl to release. CR-l is cit surge protective diQde. When K 1 contacts 11 and 7 open, the head shield cover is closed because the door solenoid is released and the remote TAPE RUNOUT lamp goes out. r r Closure of K 1 contacts 11 and 3, and 12 ana 4 applies bus potential through K7 contacts 11 and 3, K6 contacts 12 and 4, K8 contacts 11 and 3, and K5 contacts 12 and 4 through J5-14 to light STOP lamp DS3; and a path through CR13 and R5 charges C3, and operates K4. Several other paths are likewise made ready. Opening of Kl contacts 10 and 6 inserts R9 in the return path of the reel motor fields and the voltage developed across this resistor is applied through K5 contacts land 9, K6 contacts 1 and 9, K7 contacts 1 and 9 through J6-A to the armature of the rewind motor. A similar path applies the same voltage to the takeup motor through K5 contacts 2 and 10, K6 contacts 2 and 10, K7 contacts 2 and 10, and J6-2. The torque so generated is very small; sufficient to remove slack from threaded tape but not enough to cause motion of the tape from a large-diameter reel to a smaller one. When the end of the tape is threaded into the takeup reel, the transport is ready to be put into motion from its standby condition. From Standstill to Play r r Bus potential exists on switch S5 through J6-D, J2-9, and J2-10. Closure of the PLA Y pushbutton applies this through J6 -18 and CR4 to operate relay K3 momentarily. Through K7 contacts 11 and 3, K6 contacts 12 and 4, K8 contacts 11 and 3, and K3 contacts 8 and 12, K5 is caused to operate. Release of the PLA Y pushbutton releases K3 but K5 remains locked up through K5 contacts 8 and 12, K8 contacts 3 and 11 J etc. PLA Y lamp DS5 remains lit through J6-17 since it is in parallel with the coil of K5. This same supply immediately operates the ingoing capstan idler solenoid through TB2-1, clamping the tape gently, under control of a dashpot, to the capstan. The break at K5 contacts 12 and 4 removes bus voltage from C3 and the coil of K4 so that after approximately 0.5 second, K4 releases. Closure of K4 contacts 11 and 3 applies bus power to J6-12 and TB2-3 and operates the outgoing capstan idler solenoid. This occurs after the tape has accelerated to M23 RRM 2-69 105 running speed under control of the ingoing solenoid. In one-inch capstan machines, C3 is rated at 500fJ.F to delay the operation of the outgoing solenoid an additional 0.4 second. When K5 operates, the transfer of K5 contacts 2 and 10, to 6 and 10, applies full dc power through K4 contacts 6 and 10, K5 contacts 6 and 10, K6 contacts 2 and 10, and K7 contacts 2 and 10 to the takeup motor armature and a reasonably high hold-back torque to the supply motor through K4 contacts 6 and 10, RS, K5 contacts 5 and 9, K6 contacts 1 and 9, and K7 contacts 1 and 9. After the tape is up to speed and K4 releasea, the break at K4 contacts 6 and 10 inserts resistors R6l and R62 in th e armature paths to establish proper winding and holdback torques since acceleration conditions are replaced by constant-velocity operation. From Play to Stop Directly beneath the takeup r e e I hub on the take up motor shaft is mounted a ball bearing. The outer race of this bearing is not rigidly mounted but is cente red in a light-weight vane. The vane would rotate with the take up motor shaft but is prevented from doing so by two posts. The vane rests against one post when the motor turns in one direction and shifts through an angle of about 15 degrees to rest against the other post when the motor turns in the other direction. The vane carries a small magnet, which causes operation of reed switch S13 when the motor runs in the forward direction. Switch S13 is released and S14 is caused to close when the motor turns in the reverse direction. With the machine in the play mode, if the STOP pushbutton is pressed, the following takes place: Bus voltage is applied from K3 contacts 10 and 2 through J6- l l, J2-l2, J2-ll, and the closed contacts of S3, through J6-S to operate relay KS. Bus power from J6-D is applied through S13, which is closed in the forward dire c tion, through J5-lS, KS contacts 6 and 10 to operate K7. Relay K7 closes a holdi ng path for relay KS through K7 contacts 12 and S, KS contacts Sand 12, to KS t e rminal 14, so that K5 and K6 both remain operated after pressure is removed from S3. The REWIND lamp is lit through K7 contacts 11 and 7. The break at KS contacts 3 and 11 opens the holding circuit for K5 and it releases, extinguishing the PLAY lamp and dropping out the capstan idler solenoids so as to unclamp the tape from the capstan. Operation of K7 provides full torque power through K7 contacts 5 and 9 and through J6-A to the rewind motor, while the break at K7 contacts 2 and 10 removes all takeup motor torque, bringing the tape to standstill and attempting to start it in the reverse direction. Motion of the tape in the opposite dire c tion, however, causes the vane in the sense switch assembly to Leave its former position against the for w ard stop and swing toward the reverse stop. When the magnet moves away from S13, this switch opens, dropping out K7. This applies a light holding torque to the tape. When K7 releases, it releases KS by opening K7 contacts 7 and 11. Relay K4 is held closed through K7 contacts 11 and 3, K6 contacts 12 and 4, KS contacts 11 and 3, K5 contacts 12 and 4, CR13 and R5. It was previousl y operated through K7 contacts 12 and S, CR14 and R5. With the exception of K4, all relays are de-energized and STOP lamp DS3 is lit. 106 M23 RRM 2-69 [ r r r r r r r r r r r r r r r r r r From Stop to Rewind With the machine in standby, pressing REWIND pushbutton S2 causes bus voltage to be applied through K3 contacts 10 and 2, J6-11, J2-12, J2-11, S3, S2, J5-R, and K8 contacts 2 and 10 operate K7. The relay applies rewind torque through K7 contacts 5 and 9 as outlined above, and K7 locks up to the power bus through K7 contacts 11 and 7, and K8 contacts 2 and 10. The tape accelerates in the rewind direction with full power on the armature of the rewind motor. 5ince this is a dc shunt motor, it would reach a certain terminal velocity at which time tape would be loosely wound except for the following feature. As the tape comes up to speed in rewind, the armature of the takeup motor is open circuited because of the break at K7 contacts 2 and 10. It operates as a dc generator without load until a definite terminal voltage is reached, the voltage rising as the speed increases. Zener diode CR53 will not pass current until the potential across it reaches 75 volts. Therefore, when the generated voltage reaches this level, current flows through J9-4, J6-S, CR32, CR53, J6-2 and J9-3 to act as a load and effective brake on the takeup motor, limiting the maximum speed at which it will supply tape and thereby providing a controlled tension in the reel being filled. Closure of K7 contacts 12 and 8 provides a path through CR24, J6-14, and TBI to open the head shield door and through J6-15 to operate the tape lifters. From Rewind to Stop (Tape Moving in the Rewind Direction) Pressing STOP switch S3 operates relay K8 through K3 contacts 10 and 2, J6-11, J2-12, J2-11, 53, and J6-8. Since tape is moving in the rewind direction, the sense switch vane has caused SI3 to open and S14 to close. Therefore, K6 is caused to operate through J6-D, 514, and K8 contacts 5 and 9. Relay K8 is locked up through K6 contacts 11 and 7, K8 contacts 8 and 12, and K6 is held up by S14. Relay K7, however, is released by the break at K8 contacts 10 and 2 and the fact that 513 is open. The power that was supplied to the rewind motor through K7 contacts 5 and 9 is removed by its release and transferred through operation of K6 through K6 contacts 6 and 10 to the takeup motor, which now operates to bring the tape to standstill and attempts to reverse it to the forward direction. As soon as the sense switch vane moves away from S14 toward S13, 514 opens releasing K6 and placing all circuits in the standby condition. During the stopping interval, the REWIND lamp goes out and the FORWARD lamp is lit from release of K7 and operation of K6. In standby, the tape lifter solenoid is released and K-8 is released by the break at K -6 contact 7 and 11. The head cover door remains operated through 5-12, J6-M and CR-26 unless manually overriden to break S-12. Relay K4 remains energized throughout the above action, either through K7 contacts 12 and 8, CRI4; or through K6 contacts 11 and 7, CRI4; or through K7 contacts 11 and 3, K6 contacts 12 and 4, K8 contacts 11 and 3 and K5 contacts 12 and 4 and CRl3. M23 RRM 2-69 107 From Rewind to Stop (Tape Moving in Forward Direction) It is possible while shuttling the tape at high speed to have the tape moving in the forward direction but to have th e controls in the rewind mode. 1£ the STOP pushbutton is pressed at this time, KS is energized in the manner described above; how e ver, K7 is not released in favor of K6 because the sense switch vane is in position to cause SI3 to be clos ed and S14 open. Thus K7 remains energized and the t ape comes to standstill and attempts to reverse at which time the sense switch opens S13, releasing K7 and putting the machine in standby. At this time the tape lift er s are released and KS is rel ea sed by the break at K7 contacts Sand 12. The doo r solenoid remains energized thr o ugh S12 unless overridden manually to break S12 . From Stop to Forward With the machine in standby, pressing the FORWARD pushbutton causes bus voltage to be applied through K3 co ntacts 10 and 2, J6-11, J2-12, S3, S2, S4, J5-S, CRI7 and KS contacts 1 and 9 to operate K6. Relay K6 applies full torque to the takeup motor thr o ugh K6 contacts 6 and la, K7 contacts 2 and la, J6-2, and J9-3, cau s ing tape to accelerate in th e forward direction. Relay K6 locks up to the power bus th rough KS contacts 9 and I, K6 co ntacts Sand 12, and K7 contacts 3 and 11. Motor speed is limited by the action of Zener diode CR52 as described before. Closure of K6 contacts to II a nd 7 provides a path through CR24 to open the head shield door and through J6-15 to operate the tape lifters. From Forward to Stop (Tape Moving in Forward Direction) Pressing STOP switch S3 operates relay KS through K3 contacts 10 and 2, J6- l l, J2-12, J2- I I, S3 and J6-S. Since tape is moving in the forward direction, the s e ns e switch has caused SI3 to be closed and SI4 to be open. Thus, K7 is operated through J6-D, S13, J5 -1S , and KS contacts 6 and 10. Relay KS is locked up through K7 contacts 12 and S, a nd KS contacts Sand 12. Relay K6, however,. is r e l e ased by the break at KS contacts 9 and 1. The power that was supplied to the tak e up motor through K6 contacts 6 and 10 is removed by its release and transferred through closure of K7 contacts 5 and 9 to the rewind motor, which now operates to bring the tape to standstill and attempts to reverse it to the rewind direction. As soon as th e sense switch m ov e s by reversal of tape motion, it releases S13, r e l e asing K7 and placing all circuits in standby. During the stopping interval, the FORWARD lamp goes out and the REWIND lamp lights because of the release of K6 and operation of K7. In standb y, the tape lifter solenoid is r e leas e d . KS is released by K 7 conta c t Sand 12. The door sol enoid r emains energized through SI2 unless manually overridden to'break S12. lOS M23 RRM 2-69 [ r r r r r r r r r r r r r r r r r r From Forward to Stop (Tape Moving in Rewind Direction) It is possible, while shuttling tape at high speed, to have the tape moving in the rewind direction but to have the controls in the forward mode. If the STOP button is pressed at this time, K8 pulls in inthe mannerdescribedabove. However, K6 is not released in favor of K7 because 514 is held closed by the sense switch vane while 513 is open. Thus, K6 remains operated and the tape comes to standstill and attempts to reverse, at which time the sense switch opens 514, releasing K4 and putting the mechanism in standby. At this time the lifter solenoid is released, and KB is released by the break at K6 contact 7 and 11. The Door solenoid remains operated through 512 unless ma·nually overridden to break 512. From Forward to Rewind Considering the tape to be in the forward mode regardless of its actual direction, relay K6 is energized. Pressing the REWIND pushbutton closes a circuit to operate K7 through K3 contacts 10 and 2, J6-11, .53, 52, J5-R, KB contacts 2 and 10 to K7-14 through K7-13, CR19 and R6 to ground. Relay K7 operates, opening the holding path for K6 at K7 contacts 3 and 11, which releases, further breaking its holding circuit at K6 contacts 8 and 12. Torque power to the reel motors is therefore reversed. Relay K7 locks up through KB contacts 10 and 2, and K7 contacts 7 and 11. From Rewind to Forward Considering the tape to be in the rewind mode regardless of its actual direction, relay K7 is energized. Pressing the FORWARD pushbutton closes a circuit to operate K6 through K3 contacts 10 and 2, J6-11, J2-12, J2-11, 53, 52, 54, J5-5, CRI7, and KB contacts 1 and 9 to K6-14. Because J5-5 applies bus potential to CR20 as well as to CR 17, the coil of K7 is effectively shorted, since the total voltage appears across R6. This releases K7, K6 remains operated over the path K7 contacts 11 and 3, K6 contacts 12 and 8, and K8 contacts 1 and 9. Torque to the reel motors is therefore reversed. From Rewind to Play In the rewind mode, regardless of actual direction of tape motion, relayK7 and K4 is energized. Pressing PLA Y pushbutton 55 causes bus power to flow through J6-D, J2-9, J2-10, 55, J6-18, and CR4 to operate K3. A holding path is established through K7 contacts 12 and 8, K3 contacts 11 and 7, Rl, CR8 and CR7 so that K3 will not release when 55 is released. Relay K3 contacts 10 and 2 open the paths to 53, 52 and 54 pushbuttons to .render them inactive at this time. The potential from K7 contacts 12 and 8 through K 3 contacts 11 and 7, and through R 1 also feeds through CR9 to terminal 14 of K8 causing it to operate. Because this action opens the holding path of K7 through K8 contacts 10 and 2, and K7 contacts 7 and 11, an unstable condition could arise, but this is prevented by the charge in C12, which continues to hold K8 until the transfer of K7 is completed if need be. Whether K7 M23 RRM 2-69 109 continue s t o hold or to transfer to K6 is determined by the direction the tape is moving as outlined above. In an y event, operation of K8 fun c tions to bring the tape to standby co ndition. When K6 or K 7 is rel e ased by the sens e s w itch as the tape reac he s standstill and attempts to reverse, the break at K6 contacts 7 and 11 or K7 contacts 8 and 12 r e leases K8. No rmally, the machine would now remain in standby, but at this time K3 is still operate d even though its supply path through K3 contacts 7 and II is open . This is because it is held by the charge in Cl for sufficient time to perfo rm an additional function. When K8 releases, bus power is supplied through K7 contacts 11 and 3, K6 contacts 12 and 4, K8 contacts II and 3, a nd K3 contacts 8 and 12 to op e rate K5. The fun c tions from here on are as described und e r "From 5tand still to Play. " From Forward 10 Play In the fast-forward mod e, r ega rdl e ss of actua l directi o n of tape motion, r e l ay K6 and K4 is e nergized. Pr ess ing PLAY pushbutton 55 causes bus power to flo w through J6-D, J2-9, J2-10 , 55 , J6-1 8 , and CR4 to operate K3. A h o lding pa th i s established for K3 through K6 co ntacts 11 and 7, K3 contacts 11 and 7, Rl, CR8 , a nd CR7 so that K3 wi ll no t r e l ease w h e n 55 is rel ea sed. R e lay K3 opens the paths to 53 , 52, and 54 pushbutto ns to r e nd e r the m inactiv e at this time . The po t ential from K7 contacts 12 and 8 throu g h K3 contacts 11 and 7 and Rl a lso feeds thr oug h CR9 to terminal 14 of K8 ca u s ing it to operate . Because this action opens the ho lding path for K6 through K8 co ntacts 9 and 1 and K6 contacts 8 and 12, an unstable co ndition co uld aris e but is prevented by the charge in C12, which cont i nues t o hold K8 until the tr ansfe r of K6 is completed, if need be. Whether K6 con tinue s to hold or to transfe r to K 7 is d e termined by the directi o n of tape movement. In any eve n t , operation of K8 functions to bring the machine to a standb y condition. When K6 or K7 is r e l e ased by the s e nse switch as the tape reaches standstill and attempts to re ve rs e dir ec tion , the break at K6 contacts 7 and 11, or K7 c ontacts 8 and 12, releas es K8 . No rmally , the machine would no w remain in sta nd by but at this time K3 is still ene r g ized even though its supp l y p ath through K3 co nta c ts 7 and 11 is open. This is because it is held by the charge in Cl for sufficient time to perform an additional function. When K8 releases, bus power is supp li e d thr o ugh K7 c ontacts 11 and 3, K6 contacts 12 and 4, K8 contacts 11 and 3, and K3 co nta c ts 8 and 12 to e n e rgiz e K5 . Tap e Runoul W h en the ta pe runs out f r om a ny mode of operation, th e li g ht from lamp D5 8 falls up on ph oto diod e V6 0, causing K l to e ner g i ze .

Operation The record mode can be selected only when the PLA Y lamp is lit, indicating that the machine is running at normal speed. It is then necessary to press both the RECORD and RUN pushbuttons simultaneously. Bus power is applied through J6-D, J2-9, J2-10, 55, 51, JS-13, and K3 contacts 7 and 11 to operate K2, which then locks up to the holding path for KS. This path is KS contacts 8 and 12, and K2 contacts 8 and 12. The path established to hold K2 then lights D51 through J6-3 and supplies positive bus voltage to the electronics power cable through connector J4-9. Relay K2 contacts 11 and 7 also supply ground potential to the same connector through J6-T to J4-10. The positive potential is also applied through R16 and CR29 to the bias oscillator. Capacitor C7 is provided both for decoupling and for delayed decay after power is removed. Transistors 02 and 03 operate as a low power, push-pull oscillator to provide a high-frequency signal to terminals J6 - U and J6 - V. The electronics assembly cable conducts high-frequency bias to all bias boards in the electronics through J4-1 and J4-2. The oscillator is tuned to 120 kHz by capacitor C 11. Speed Change Switch Speed change switch 5 selects windings of the capstan motor to provide either of two speeds. These are related by the ratio 2: 1 and therefore can be provided for tape sp~eds of 3-3/4 and 7-1/2 ips, 7-1/2 and 15 ips, and 15 and 30 ips, etc. Dc bus potential is supplied to either J4-6 or J4-7 in the electronics power cable, depending on the motor speed, in order to control equalizer-select relays in the electronics circuit boards. Reel Size Switch Reel size switch 57 provides for adjustment of torque in fast forward or in rewind when one spindle carries the normal large reel and the other carries a light-weight reel. If both reels are the same size, the switch is left in the center BALANCE position. If the large reel is on the tape takeup side, the switch is moved toward the right, or toward the large reel (in the direction of the arrowhead on the panel). If the la rge reel is on the left, or supply side, the switch is moved to the left. In the center position, 57 connects JS-N to J6-1 and JS-IS. If K6 is energized, putting the machine into fast forward, heavy dc current flows through the takeup motor, returning to the negative supply through R60. Thus JS-L is a few volts more negative than J6 -So This negative potential is applied through CR30, S7, and Rll to the rewind motor, causing it to develop small torque in the same direction the takeup motor tends to turn. This aids acceleration. Similarly, in rewind, RIO supplies reverse torque to the takeup motor, assisting in getting the tape up to high speed. When a small reel is on one side, however, this assistance is not desirable since it may tend to unwind tape faster than the other M23 RRM 2-69 III ree L c an spooL it. Thus S7 provides for breaking the negative Lin e throu gh RIO or R I I as needed. This feature is on Ly appLicable to 1 / 2 and I-inch machines. The swi t c h , although provid e d, is in a ctive in I /4 -in ch machines. TORQUE CONTROL RELAY !'i4-inch machines only) Due to the light weight and ine rti a of the smal l p lasti c reels commonly used on I /4-inch machin es, there is a te nd e ncy for a loop to form in the tape between the outgoing tap e g uide and the r ee L r ece iving the tape if negative torque is app li e d through RIO or RII before the tape has come to rest and started to move in the opposite dir e c tion . To prevent revers e torque from being applied until the tape has begun to traveL in th e direction of the se l e cte d mode, KI3 is installed in th e socket provided on the transport near the re w i nd moto r. Ree l size switch S7 is not co nn ec ted as sta t e d above . Consider the t a pe to be in motion in the fast forward dire c tion with K6 energiz e d. Pr ess ing the REWI N D pushbutton energizes K7 and reLeases K6. Drive torque is immediate Ly t ransf e rr ed fr om the take -up motor to the re w ind motor. Due to the momentum of the reels travelin g in the forward direction, the tape does not come to a n immediate stop but continu es to t raveL in the forward direction until this momentum is overcome by the dynami c braking action ca used by the reverse torque applied to the r ew ind moto r, which is attempting to pull the tape in the oppos it e direction. Du r ing this slow down period, dir ec tion a L sense switch SI4 is open, which maintains KI3 in the d ee nergized position . The refore, the c ir cuit path to the take -up moto r a r matu re is broken at K 13 contacts 5 a nd 9, c ausing the motor to coa st to a stop und e r th e braking action of th e r e wind motor onL y. As the tape mot i on co mes to r est and starts to rev e rse its dir ect i on, SI4 closes. Buss power is applied to KI3 , prov idin g negative torque power th roug h co nt acts 5 and 9 , RIO, etc . , to t he tak e -up motor and ca using it to turn in the same dire c tion as the r ewind motor . This action r educes th e dra g on the r ewind moto r and aids acceleration a s des c ribed under ' ·Reel Size Switch." Thus, KI3, in con ju nct ion w ith dir ect ional sensin g swit c h SI4, prevent s negative torque power from being applied to the appropri a t e r ee l moto r ui'l'il the tape has come to r est and starts to acce lerate in the opposite dire c tion . Ma n itor Switch in" T wo pushbuttons on the transport , S10 and 511, are arranged to transfer the output Li ne amplifier and VU meter of e ach e l ec tronics ci r cuit board from the incom ing signa L source to the pLayback a nd vic e versa. P r essing A switch SID applies bus vo ltage from J6-D th rough J 2 - 9, J2- I O, and S ID to J4-5, w hich is in the eLectronics power co nn ec tor, causihg operation of tr a nsfer rela y s in each moduL-e. Simi l a rl y B switch SII applies bus potentia l to terminal J4 -4 to cause reverse op e rat ion o f the transfer r e lays. These sw it ches are momentary-contact types and a r e not Lighted. 112 M23 RRM 2-69 r L l L Runout Switch The runout switch is provided on all models of the machine. The sensing circuits associated with the switch are furnished on aLL series A transports but are furnished on B transports only on special order. When connected, it provides for automatic stopping of the tape before runout, automatic rewind at the end of the tape, and automatic starting of a second machine under either of these conditions. The circuit is actuated when light from an exciter lamp faLLs upon a photo sensor through a "window" in the tape. Fail-Safe Brakes r r For certain applications, it is desirable to include self-energizing mechanical brakes on the transport to prevent a tape spiLL if power fails. The faiL- safe brakes, which are provided on special order, are released whenever power is on and are applied when the machine is turned off or power interrupted. Solenoid L6 is energized directly from the low-voltage dc supply. When it operates to lift the brakes, microswitch SIS is opened, inserting ISO-ohm resistor R73 into its path to prevent overheating of the solenoid winding. L SIGNAL ELECTRONICS FUNCTIONS L r r r r L r r Signal electronics consist of record amplifiers, which raise the input signal to a level required by the record (heads), a bias and erase frequency power supply, and equalizer circuits and amplifiers to reproduce the signal recovered by the playback heads. Each complete electronics assembly includes a power supply, controls, and a volume indicator (VU meter). Signal processing is either in conformance to NAB standards or Dynatrack operation. In Dynatrack recording and playback, two tracks are used. One track records at the standard NAB level, this is the H track; and the other track records the identical information, but records high frequency signals at a higher level (more recording gain), employing a pre -empha sis curve rising 15 db from 400 cyc le s to 15,000 cycles. When the tape is reproduced, the output is switched between the L and H tracks depending upon the amplitude of the recorded signal. When the recorded signal is at a low level the L track will provide the signal output and, of course, deemphasis of the previously pre-emphasized signal. When the amplitude of the recorded signal increase to where the distortion of the L track approaches 1 percent, the output wiLL switch to the H track. Switch over from the L track to the H track, and vice versa, is automatic during the reproduce precess. The switchover is fast enough so that no discontinuity is apparent to the listener. The overdub feature allows a record head to be used as a playback head so that a second track can be recorded in synchronism with a pre-recorded signal. This feature avoids the time lag that would occur if the playback head were to be used for monitoring during overdub operation. M23 RRM 2-69 113 NAB ELECTRONICS One electronics module is e mployed for each compatible NAB equalized track. Thu s , in a 1 /2-inch machine having standard four track heads four channels of NAB equalized signals may be record e d. In this case four electronic assemblies are requir e d, equipped with the proper board for NAB service. If it is desired to employ the Dynatrack system, two tape tracks are required to each channel. Therefore. the four-track configuration permits a two channel Dynatrack system and only two electronic assemblies are employed, equipped with the proper cards for Dynatrack operation. Electronic Assembli e s are readily converted from Dynatrack to NAB and v ice versa by rperely changing boards and head cable connectors at the rear of the a ssemblies. The following d e scribes the operation of a complete electronics a ss e mbly arranged for NAB service. Th e indiv idual plug-in boards will be fully described after an outline of their fun ction in relation to their servi c e in the overall operation . Refer to figures 37 and 38 during the following discussion. The rectangular dashed areas represent plug-in unit s . The numbers in ovals r e present connector pin numbers. NAB Recording The signal to be recorded is applied through connector Jl 0 1 to the primary of transformer Tl, which reflects an impedance of 20,000 ohms to the signal source. Input is through a two-wire shielded cable with the signal lines ungrounded. The sec ondary of Tl is connected across RECORD LEVEL control RIOO, which establishes the level of the signal applied to the record amplifier. This amplifier provides pre-emphasis, equalization, and linearization to the signal, and sufficient gain to drive the record head. A relay on the board selects equalization networks for t he two tape speeds used. Linearization is selectable by means of a switch on the circuit board and is adjustable. The degree of linearization required depends on t he signal level, and corrects for distortion that occurs as the signal level approaches the saturation level of the tape. A pilot tone, used for tape-speed control, may be introduced by way of connector JIll-I, and terminal 16 of the H and NAB Record board, to be mixed with the normal input signal. The pilot tone may be either supersonic or subsonic. A separate amplifier is included on the H and NAB Record Board to bring the input signal to sufficient level to apply to the monitoring circuits so that this signal ma y be listened to and observed on the VU meter. A variable control RECORD MON. CAL. enables the meter to be adjusted so that, without the linearizer in service, 30/0 total harmonic distortion on playback results at 6 db above zero VU. 114 M23 RRM 2-69 r l i;.' .r· r r r r r Ii r, i .•; i I,~ r'·; r r r ~..,I r·.',:· r, r r The maln signal from the record board appears on the record relay KI0l at terminal 9. It is normally grounded through KIOI contact 9 and 1 but when KI0l is operated the signal is applied. through KIOI contact 9 and 5 to the H Bias and Erase Board (1) in slot 1. ~7henever the RECORD button on the transport is activated, an oscillator in the transport is energized and provides 120kHz from JII0 terminal 1 and 2 to terminals 14 and 15 of this board and all other identical boards in the other electronic assemblies of a multi-channel recorder. A power amplifier feeds the 120 kHz bias signal through a variable resistor BIAS AMP to provide the proper rnagnitude of bias to the record head through terminal 1. The audio signal from terminal 22 is also passed to terminal 1 through. a bias trap circuit which has no effect on the audio signal, but prevents drainage of bias power back through the record amplifier board. A noise balance control is provided which injects an adjustable DC component into the record head to correct for external fixed magnetic fields in the vicinity of the record head gap. In order to monitor the bias and audio signal mixture by means of an oscilloscope or vtvm, the record head is returned to terminal 2 which is removed from ground by 10 ohms. Monitoring is at the TP BIAS test point and a variable control permits the VU meter, when connected to terminal 3, (set to BIAS) to be calibrated to a fixed number on its scale (-5 VU for example~ A second power amplifier, also driven by the 120 kHz signal, applies its output through terminal 21 to terminal 20 of the NAB Erase Coupler Board (3N) in slot 3. The signal passes through an adjustable capacitance to terminal 11, and from there to the erase head. There is a feedback path through board 3N terminal 19, and board 1 terminal 19, to control the amount of drive of the erase amplifier. The amount of feedback is controlled by the feedback resistor. The amplitude of the erase current may be monitored at the TP. ERASE test point on board 3N. The VU meter may be calibrated by varia ble resistor ERASE MON. CAL. which is feeding via terminal 22 to the VU monitor. Typical calibration provides a VU when erase current is adequate. In addition to transferring the record amplifier output from ground to the bias amplifier board, relay KIa 1 also causes indicator lamp DSI03 to light through contacts 12 and 8 and applies +28 volts to energize the bias and erase amplifiers at terminal 12 on the H Bias and Erase board (1). Another pair of contacts is used during Dynatrack operation and is discussed under that heading. Inductive surge from the coil of KI0I is suppressed by diode CRIal. r r r r'·, f( i M23 RRM 2-69 115 NAB Reproduction Signals recorded by the H and NAB record circuits described above are reproduced from the corresponding playback head and applied to the H and NAB preamp lifier board in slot 7. The pr eam plifier board -contains high-frequency and low- f requency amplitude equalizers for two tape speeds. The proper equalizers are sele cte d by a relay on the board, which is energized by a voltage introduced through terminal 20. High-frequency and low-frequency equalizer networks are provided for each tape speed. Phase correction networks are selected by another relay with a separate network for each speed. This relay is energized by a voltage introduced through terminal 19. The phase correction networks are not adjustable . At the pilot connector JIll all signals may be fed out on terminal 2 with return on 5, in order that the pilot , if any, may be extracted free from gain variations occasioned by adjustment of the GAIN CAL . potentiometer which feeds the main audio signal out on terminal 22. A jumper loop is provided on the terminals 17 and 16 of slot S when machines are furnished from the factory with only NAB boards . No card is then provided for slot S and the signal bypasses the slot directly to the REC. SELECT switch 103. Since it is necessary to provide a preamplifier and electronic switch card in slot S when the Dynatrack system is employed, this l oop must be clipped open and later if conv e rted again to NAB operation an NAB conversion card (SN) must be inserted in slot S when the Dynatrack card is removed. This card is blank except for a jumper loop between terminals 17 and 16, to again close the loop previously clipped. It is furnished with the Dynatrack conversion kit. When the REC. SELECT switch is in the RDY position, the record head is connected to the output of the H bias and erase board; +2S volts is supplied from the pow er and meter assembly in slot 5 through terminal 12 to this switch, to terminal 13 of the r eco rd relay so that it may be operated by grounding its terminal 14 through diod e CRI02; and to terminal 10 of JIIO at the tape transport. The signal from terminal 16 of slot S is routed through the REC . SELECT switch to the REPRO. LEVEL control and an attenuator comprising RI04 and R105. With the METER switch in the CAL. position, the signal from the attenuator is rout e d to the line amplifier circuit card in slot 6, where it is ampLified and applied to the outgoing line . A selector switch at the output of the line ampLifier normaLLy connects the output through terminal 2 L to transformer T2, w hich is provided with imp e dance matching resistors RIOS and RL09. The output impedance may be set by means of switch Sl06 to 150 or 600 ohms. Switch Sl05 is a three position switch providing 150 - ohm, or 600 - ohm termination of the outgoing line when it is not terminated externally. The outgoing lin e connects to connector JI02. When the seLector swit c h at the amplifier output is set to route the signal to terminal 20, an S - ohm lous d peaker may be driven directly from terminal 3 of PILOT connector Jill. 116 M2 3 RRM 2-69 r r r r r r r r r r r r r r f',:·.;" ( r r r r Speaker return is to terminal 6. Earphone monitoring is provided by jack JI03. This jack is "floating" and headphone leads should not be grounded. The output signal from T2 is applied through terminals 2 and 4 of the line amplifier board to an attenuator which supplies the attenuated signal for the VU meter through terminals 3 and 4, through the METER switch in positions 1 and 2, to terminals 14 and 16 on the power and meter assembly. Resistors in the attenuator may be changed to modify the working level from the +4 dbm normally provided. See table 10. Choice of 150ohm or 600-ohm output does not appreciably modify the VU meter reading. Since the meter attenuator is fixed for any given operating line level, and the fixed gain attenuator R 104 and R 1 05 is selected in the CAL. position of the METER switch, it is only necessary to adjust the GAIN CAL. potentiometer on the playback preamplifier board (7 and 7/9) to assure that a standard reference level tape is reproduced at the proper indicated level. Typically, such tapes provide a reference tone of 700 cycles which should read zero VU, attainable by adjustment of this control. Having been so calibrated, the METER switch may be turned to the SIGNAL position. The REPRO. LEVEL gain control is then substituted for the calibrated attenuator, to provide convenient adjustment of playback level. When in this position, the signal output may be either the tape playback or the input signal. This transfer is provided by KI02 contacts 8, 4, and 12 under control of pushbuttons S101 and S102, the A-B output selectors. Note that when the METER switch is in the SIGNAL, ERASE, and BIAS positions, the audio signal is always fed in the same manner to the output, although the meter is connected to various circuits. The Meter and Power Assembly, located in slot 5, is powered from the transport through JII0 terminals 11 and 12. It provides regulated +28 volts at terminal 12 of all electronics. Non regulated dc is provided at terminal 18 to power the coil of KI02 and the A and B lamps. 24 volts AC is provided at terminals 2 and 3 for external use, if needed. A resistor may be replaced with alternate values to provide control of the girghtness of the lamps in a remote meter fed from terminals 3 and 7 through the remote meter connector JI09 terminals 3 and 6. One position of the REC. SELECT switch, S103, has been discussed, the RDY position. In the SAFE position the coil of K 101 is opened so that the record electronics are locked off to provide maximum protection for previously recorded tapes. All other circuits remain normal. In the O. DUB position the record head is completely disconnected from its normal feed and becomes a playback head. When the record head is so connected, it feeds terminals 10 and 14 of the Overdub Preamplifier (7/9) in slot 9. This preamplifier is identical to the Hand NAB preamplifier previously described except for the addition of an input transformer. When the record head is used in playback it matches closely the frequency response and gain of the normal pLayback head. Due to its wider gap, however, the extremely high frequencies suffer some attenuation depending upon the tape speed. M23 RRM 2-69 117 If the overdub feature is desired, it is highly recommended that a separate preamplifier be employed in each position; a 7 board in slot 7 and a 7/9 board in slot 9. It is not necessary that the user have both the H and NAB Preamplifier and the Overdub Preamplifier since the latter may be extracted from slot 9 and reinser t ed in sLot 7. The input transformer is then bypassed and operation is identical to the normal preamplifier. DYNATRACK ELECTRONICS Read the above description of the NAB electronics for more details of certain aspects of the electronics common to both systems. Refer to the electronics block diagram, figure 34. As in the description for NAB above, the signal is recorded directly on the H or NAB track. There is a tap in the H and NAB Record Board which is not used for normal NAB recording, but which feeds out the signal fully equalized for NAB operation on terminal 2. This is applied to the L Record and Bias Board (3D) in slot 3 . No te that this replaces the NAB Erase Coupler Board (3D) used for NAB reco r ding. Board 3D provides a r eco rd amplifier to driv e the second, or L, record head; and it includes the special equalizer required by the Dynatrack system. It includes a linearizer as previously described. Its output through terminal 15 is fed to the r eco rd relay KIOI, whe re it is normally grounded by contacts 10 and 2. During recording, the signal is fed from KIOI contacts 10 and 6 back to terminal 16 where it passes throug h a tuned bias trap, and picks up bias injected at terminal21. The signal goes out on terminal IS to the record head for the L track. The record head return lead is to g round . TP. BIAS provides a test point and the BIAS MaN CAL. control permits calibration of the VU meter to indicate proper bias current for the L track when the meter switch is in the ERASE position. Terminals I I and 20 have no connection on this board; these were used to furnish power to the erase head in the NAB configuration. When Dynatrack is employed no erasing facility is provi ded. Instead, the erase power ampLifier on the board in slot I is used to feed power on terminal 20 to terminal 21 on the L Record and Bias Board, where the BIAS ADJ control provides adjustment of bias current in the head. The feedback resistor feeds from terminal 19 of the H Bias and E rase Board and in this case a lower resistance holds down the excitation of the am plifier to a greater degree than when it is used for erase power. The LEVEL control on th e Dynatrack L Record Amplifier board provides for p roper adjustm ent of the r eco rded level of the L track with respect to the H track, for any given frequency. On playback the H track is reproduced in the normal manner by the board in slot 7 as described abov e . The L track, on the other hand, is r ep roduced by the L Preamp and Switch Board (SD) which must be inserted in liS M23 RRM 2-69 ,· f ( r r r r r r r r r·.' r r·.· , r r " I r r r r slot S. As described above, when this is employed the NAB conversion board (SN) must be removed from slot S to break the connection between terminals 17 and 16. H this board was not previously provided the link between terminal 17 and 16 behind the connector must be cut, since it is necessary for the signal from the H track to pass through the electronic switch on the L preamp and Switch board. In addition to providing a preamplifier, it is necessary for this board to provide equalization to deemphasize the specially recorded characteristic of the L track. Thus at terminal 16 the signal is identical in frequency response and level to that from the H track coming in on terminal 17. Since the L track is recorded at a much higher revel than the H track for some frequencies, it is necessary to switch from "L" to flHfI at high signal levels, and this is done by the electronic switch under control of its Schmitt trigger. The switching level is determined by the setting of the TRIG. control. Following the switch an output amplifier feeds the signal to the line amplifier, etc., in exactly the same manner as previously described. The L preamplifier and switch board also includes variable equalizers to permit adjustment of overall frequency response, and phase equalization for 15 ips, since the Dynatrack system is designed to be operated only at this speed. DETAILED CIRCUIT DESCRIPTIONS The following paragraphs contain detailed descriptions of each of the circuit boards, and the Meter and Power Supply Assembly. H and NAB Record Amplifier (4) (See Figure 39) The input signal to be recorded is applied at terminal 14, after it has pas sed through the input transformer and level control. Cl couples it to Ql, which is biased to the proper operating point by R 1 and R2. After amplification the signal is coupled by C3 to an equalizer network, producing a preemphasis characteristic at the high and low frequency extremities of the spectrum in accordance with standard NAB practice. This is accomplished as follows. Consider R6 and R7 as an attenuator network, with RS short circuited, as it effectively is at high frequencies because of C4 and C5. This attenuator network reduces the voltage swing at the junction of R6 and R7 from what it was at collector of Q1. However, if a bypass capacitor CIS or C19 is connected across R6 it permits the high frequencies to suffer less attenuation. The degree to which this is true depends on the setting of the variable capacitor. Practical values of C IS and C 19 make it necessary for the junction of R6 and R7 to appear always as a very high impedance. Current cannot be drawn from this point without upsetting the equalization characteristic. Thus, the junction is used to drive a field effect transistor, Q2. C4 and C5 show increasing impedance as the signal frequency is lowered; M23 RRM 2-69 119 therefore, the voltage at the junction of R6 and R7 would continue to rise as the frequency drops, except that R8 provides a shelving off to prevent unnecessary sensitivity to subaudible frequencie s. Relay K 1 automatically changes the high frequency equalization when tape speed is changed. The output of Q 2 is applied to terminals into which may be inserted values of C8, C20, Rll, and Rl2 to adjust for any requirement arising for shelving equalization in addition to the normal NAB equalizers just described. All four components may be eliminated in many instances, a jumper being furnished acros s the R 11 or C20 terminals. After this network the signal is fed to the base of Q3 whose bias is set by Rl3 , RI4, and R15. This operates with Q4 in a Darlington circuit to provide gain and low impedance output at C II to drive the NAB record head. R 18 normally prov i des a degree of degeneration, determined by the setting of R20, and R 19 in seri e s with CI2, and C21. But the degree of degeneration can also be reduced by conduction of Q5 and Q6 when 51 is closed. Q5 and Q6 act to change the degeneration with instantaneous signal amplitude, thus they tend to deform the signal whenever its amplitude attains a value sufficient to overcome their contact potential. This results in a distortion, inverse to that which overload of the tape normally introduc e s. By employing Q5 and Q6 in this manner, and properly adjusting the overall degeneration by means of R20, the LIN ADJ. control it is possible to introduce the prop e r corrective distortion into the recording process so that the normal 30/0 tape dist o rtion point shows somewhat l e ss than 10/0. Cll feeds the record head connected at terminal 22. R22 is a resistor in seri e s with the head to establish a constant current characteristic. R23 provides a hi g h resistance path to ground so that the ground side of Cll will always be discharged, even when no head is connected to terminal 22. This is a menas of preventi ng accidental record head magnetization. The signal effective in driving the record head may be extracted at terminal 2 to be applied to the L track record amplifier when the Dynatrack system is employed . Terminal 16 provides a point for injecting a pilot frequency for playback tap e speed control. This is useful in motion picture synchronization. The pilot for e ither a high or low frequenc y s ystem may be employed. C 14 couples the input sign a l to Q7. The gain of Q7 is adjusted by the combination of emitter resistors R27 and R28, which is bypassed by CI6 to provide the proper range of signal levels to R 3 0. This control, RECORD M aN CAL., can be conveniently adjusted to serve the input signal audio monitoring and input signal VU meter monitoring circuits. R2 9 a nd C 17 are provided to give a slight rise in output at 15 kc to make up for los se s in the input transformer, w iring, and meter sensitivity occurring at the extr e me end of the spectruIT). 120 M23 RRM 2-69 r r r r r r r r r r r 1.( r' ! [ r·. i' f r r L Record and Bias (3D) (See Figure38) Signals to be recorded are first applied to the NAB record board (H and NAB Record Amplifier) (4), and after proper equalization to obtain the NAB recording characteristic, the signal is fed to this board at terminal 2. Since this amplifier must adequately record signals of extremely low level, it is essential that it contribute a minimum of self-generated noise. Therefore, 01 which must be fed from a comparatively high impedance source, is a field effect transistor. Its output feeds the LEVEL control whose output feeds 02. Since R9 is a relatively high resistance, 510 ohms, degeneration is high in this stage. It is bypassed by the network R7, CS, and C6; and these capacitors begin to take effect above 400 Hz, causing the gain of the stage to rise. R7 provides a limit to the rise so that the gain of 02 shelves off at 15 kHz, 8 db above its 400 Hz value. The outp'ut of 02 is coupled to 03 where a similar operation occurs with about 7 db lift at 15 kHz. These two equalizer amplifiers provide a rising frequency response starting at 400 Hz and shelving flat at 15 kHz with a total of 15 db rise. This gives the distinctive record equalization of the Dynatrack system. Ll and C8 constitute a series resonant bias trap (120 kc). The signal from 03 is applied to the Darlington amplifier 04 and OS, and the output and linearity features are the same as described above for the NAB record board. The signal output from this record amplifier goes from terminal 15 to the record relay, then returns to terminal 16, going through the bias trap L2, C19 to terminal 18 and then directly to the record head. Bias power from the bias and erase board is applied at terminal 21. C 16 tunes the output stage of the bias amplifier to resonance through the return lead on terminal 13. R3I, fed from CI8 provides feedback control of the bias power amplifier by connection to terminal 19. R32 BIAS ADJ. adjusts the amount of bias applied to the record head. CRI and CR2 feed both ends of the NOISE BAL. potentiometer R28. Consider the wiper run up to the top. CR 1 then supplies a positive potential directly to R29. R30 allows some current of positive polarity to leak through R32 and the record head. If the wiper is run all the way to the bottom, CR2 supplies a negative polarity and the DC current in the head is in the opposite direction. By varying the position of the arm more or less DC current can be permitted to flow through the head in either direction to balance out residual magnetization of the record head or strong external constant magnetic fields, during the recording process. Terminals 14, 17, and 22 provide connection to the VU meter when the METER switch is in the ERASE position. R26, BIAS MON. CAL., provides for calibration of the monitoring meter when it reads the bias strength. When the recording circuit is adjusted to provide proper bias to the head for optimum performance, this control should be adjusted to read -5 VU, and then left without further adjustment for refer ence purposes. r r r M23 RRM 2-69 121 Bias and Erase Amplifier (1) (See Figure 36) Whenever the transport is put into the recording mode, a 120 kc signal is gen er ated within the transport, and applied to all electronics assemblies where it appe a rs on terminals 14 and 15 of e ach Bias and Erase Amplifier. TI operates as a bridging transformer. It has t wo secondaries. One of these feeds the base of Q2 through resistor R4. This resistor is employed to permit insertion of a feedback signa l from R2i\ . QI amplifies the 120 kHz signal and provides sufficient power to driv e the push mil amplifier Q5 and Q6. CI3 and CI4 tune the secondary of T4, and C l6 and CI7 tune the primar y of T5 in order to minimize harmonic distortion . Eve n order harmonics are particularly objectionable since they result in increased bac kg round noise recorded into the tape. The output of 05 and Q6 is fe d through T5 and CI8 to RI9 and R24, the latter vari a ble to control the amount of l20 kHz bias signal fed through terminal I to the rec o rd head. The audio signal comes from the record amplifier and is applied at ter m inal 22. It passes without loss through the tuned circuit L2, C19, and C21 sin ce this is only tuned to present a high impedance to 120 kHz, thus preventing loes of bias power back into the record amplifier. CR2 and CR3 each operate as half wave rectifiers. If the arm of R23 is run to t he end connected to CR2, then the upper end of R21 will have an average negative potential. Conversely, if the arm is run to the other end, then the upper end of R2l will have an average positive pot e ntial. R20 allows current set up by such potential to flow through R 19 and R24 to the record head, thereby making it possible to inject a v e ry small but adjustable DC current into the head in addition to the audio and bias frequencies to allow minimization of noise resulting from strong external magnetic field s or even order harmonic distortion from the bias supply. These circuits are activat e d by application of potential at terminal 12. In ord e r to prevent a recorded thump w hen the record button is depressed, R27 and C20 are provided to permit the DC bias on the base of QI to rise slowly, and Cl5 is prov ided across RI7 for the sam e purpose on Q5 and Q6. The bias envelope therefor e grows to operating level in a m atter of about 10 milliseconds. When the recording mode is deactivated another thump or click is avoided by allowing reservoir capacitor C2 t o permit the bias waveform to decay to zero over a period of about 60 millisec onds. R I allow s C2 to charg e at a reasonable rate when the circuits are activated wit h out causing a surge on the po we r supply, but CR I permits the capacitor to be connected directly to the load during discharge. LI and CI constitute a filter to stop bia s frequency ripple on the pow e r bus connected to terminal 12. The amount of drive applied to Q5 and Q6 is controlled by feedback resistor R2 6 , which also improves the wavef orm at the output by cancelling out internally gen e rated distortion products. 122 M2 3 RRM 2-69 r r r r r The second winding of T 1 feeds the 120 kHz signal to an almost identical circuit except that the output transistors 03 and 04 have a higher powe r rating in order to supply the erase head with sufficient drive to completely erase a saturated tape. The description above applies except for a few points. The secondary of T3 is tapped to provide two output impedances. One of these, connected to terminal 21 supplies erase power in the case of a NAB setup. In Dynatrack operation no eraser is excited and power is fed from terminal 20 to the record head of the L channel. This amplifier then operates as a bias supply rather than an erase supply. The feedback resistor, which in this case is external to the board, is connected between terminals 21 and 19 in the erase setup and between 20 and 19 in the Dynatrack setup. The resistor values are naturally different for the two cases. Erase or L bias current is monitored across the 10 ohm resistor R29 between terminals 16 and ground. The NAB or H bias current is monitored from terminal 2, the record head return lead to ground, with R25 providing the meter calibration. This bias current is read on the meter when the meter switch is in the BIAS position. Meter calibration for the monitoring taken across R29 is accomplished by a control on the L Record Amplifier Board when Dynatrack is employed, or by a control on the NAB conversion board which fits into the slot occupied by Dynatrack's L Record Board (slot 3) when the electronics are converted to NAB operation. In the Dynatrack system the meter then indicates bias for the L track. In the NAB system it reads erase current. In either case, the reading is obtained by putting the meter switch into the ERASE position. H and NAB Preamplifier (7) (See Figure 42) This plug-in printed circuit board assembly provides the required signal amplification of the playback head signal to drive the output line amplifier. In addition, the as sembly performs the necessary frequency equalization and phase correction for two tape speeds. The playback head for the NAB or Dynatrack H track is connected to the assembly through terminal 4 which provides the signal path through C 1 and R2 to the base of 01, the first amplifier stage. The collector of 01 is direct coupled to the base of 02, providing a signal path and DC bias to the second amplifier stage. The output of Q2 is direct coupled to the base of 03. A feedback path is also provided from the collector of Q2 through one of two RC frequency equalization networks to the emitter of 01. Relay K 1 in the normal or deenergized condition (as shown for high speed tape operation) places C7, RlS, R19, and R20 in the feedback path. When K1 is energized, CS, R21, R22, and R23 are placed in the feedback path, providing the proper frequency equalization for slow speed tape operation. C7 (or CS) with R20 (or R23) controls the point where the customary 6 db per octave correction becomes no longer effective at higher frequencies. R 19 (or R22) controls the point at very low frequencies where the relation again no longer holds true and the amplifier shelves off. The proper operating point for Q1 and Q2 is maintained by the dc bias established at the junction of M23 RRM 2-69 123 R8 an d R9 in the emitter circuit of Q2 . This dc b ias is applied through R5 to the bas e of QI, thu s providin g a con tro ll e d amount of negative feedback to QI in relation to th e input signal lev e l.

C5 , which couples th e co llec tor s ignal to th e bas e of Q4 , pr e sents a hi g h imp e dance to the low frequenci e s c ontained in th e recorded s i g n a l. RI3 (or Rl3 in series with R14 , depending upon t h e state of K2) feeds the emi tte r si g nal directly to the base of Q4. As a result of this action, the l o w fr e quen c y ph ase co mponents present at the emitter of Q3 predomi n at e at the bas e of Q4 and a r e 18 0 d e grees out of phas e with the same signal at the c o ll ec tor of Q 3 . C onv e rs e l y , c a pa c i t or C 5 pres e nts a ver y low impedance to th e high e r si g nal frequenci e s a llowi ng t h e m to pass readily to the base of Q4. At intermediate frequ e n c ie s , the vector sum of RI3 (R13 and R14) causes the sign a l to be applied to the bas e of Q4 at some intermediat e phase angle between zero and 18 0 d e grees while the amplitud e remains constant throughout the entire frequency ran g e . The r e sult of this frequ e n cy/ phase shift action cancels the inherent phase di s t o rti o n on the signal c aus e d b y th e ma g netic transfe r characteristics when the sign a l was recorded on th e tap e . In fast tape speed oper a tio n , Kl is deen e rgized as shown . During slow tape speed op e r a tion K 1 is en e rgiz e d wh i c h r e moves R 14 from the circuit.

Filtering of the pilot from the r e maining signals must b e ac com p li shed externally of the signal e lectronics provi ded with the Series 400 equip me nt. Q5 is a seri e s voltage r eg ul a tor which provides regulated power frOlTI the input bus terminal 12 to ~he four t r a nsistor stages in this assemb l y . R 24 and R25 est ab lishe s the proper ope rating p oint for Q5, thus e stablishing a fixed voltage drop acr os s Q5. CIS provides filt e ri ng of an y pow er supply ripple on the regulated volt a ge. C9 filters any ripple at t h e bas e of Q5. 124 M2 3 RRM 2 -69 r r r r H and NAB Preamplifi.r with Overdub (7/9) (5 •• Figur. 44) This unit is exactly the same as the IIHII and NAB preamplifier described above and is interchangeable with it. It includes an input transformer which is employed when it is desired to monitor a recording using a record head as a playback head for synchronizing purposes. In this application the record head is connected to terminals 14 and 17. The output of T1 at terminal· 16 is automatically connected to input terminal 4 when this card is inserted in slot 9. r r r L Maximum convenience is afforded if a conventional H and NAB preamplifier or an overdub preamplifier is inserted in slot 7 and an overdub preamplifier is also inserted in slot 9, since it is then only necessary to"employ the record select switch to change from normal record to overdub operation. Economy but less convenience is obtained with a single overdub preamplifier, changing its location from slot 7 to slot 9 when changing the switch from normal record to overdub. Great care must be exercised to turn off the machine completely before moving the 7/9 card from slot 9 to slot 7 since the playback head may be magnetized from a charge residual on C 1 unless sufficient time is permitted for it to discharge completely. Line Amplifier (6) (See Figure 41) This is a full-spectrum flat response amplifier which provides sufficient gain and output power to adequately drive an outgoing line at up to peak level of +28 dbm (600 ohms) or to drive a loudspeaker with up to one watt peak excitation (distortion 1% THD). Ql is an emitter follower accepting an input impedance of 10, 000 ohms or lower, and providing low impedance excitation for Q2. Q2 drives Q3 and Q4 (complementary symmetry types) to result in push-pull excitation of Q5 and Q6. A required static potential difference between the bases of Q3 and Q4 is established by the contact potential drop across CRI, CR2, and CR3. CR4, R20, and C 12; CR5, R 19, and C 11 are drift compensation networks to stabilize the operating points of Q5 and Q6. DC operating point for these two transistors is set by RI3, RI4, and RIS; and Q2, Q3, and Q4. A feedback path through C 13, R21, and R22 assures minimum distortion for all signal frequencies. CIS and R23 provide a stabilization network to reduce the pos sibility of high frequency oscillations (parasitics) when certain types of loudspeakers are connected through 51 to terminal 20, and ground. In the alternate switch position the amplifier feeds out on either terminal 21 or 22 to the matching output transformer mounted in the main module, whose purpose is to match the amplifier to a 150 or 600 ohm line. R24 provides a small impedance in series with certain type transformers which would otherwise approach a short circuit at extremely low frequencies and thereby upset the stability of the amplifier at frequencies in the order of one cycle or 1es s. M23 RRM 2-69 125 R I and R3 are fixed resistor s which may be readily changed to alternate valu es to change the working line l e v e l as indicated by the VU meter . The amplifier is no r ma lly equipped with the prop e r values for reading a plus four dbm 600 ohm line. To operate from a +6, +B, or + 14 dbm, 600 ohm line, se l ect ±5% calibrating resis t ors according to the following table 10. Table 10.

L Preamplifier and Switch (80) (Se e Fi gure 43) The p l ayback head for the L t ra ck in the Dynatrack system is connected with the s ignal l ead at termina l 6, th e signa l return at terminal 7, and the shield of the conne cting cab l e w hich covers the s e two conductors is connected to B. By the shortest p ossible physical path the signal is coupl ed through Cl to the base of Q1. The signal and dc output of Q l ar e a ppli e d to the base of Q2 where they are amplifi ed . The signa l is fed back to the e mit te r of Ql through the equalizer network Cl l , R47, R4B , and R49 . Cll with R49 contro l s the point where the customa r y 6 db per octave correction becomes no longer e ff ec tive at high f r equencies. R48 controls the point at v e ry l ow frequencies where the re l ation no longer holds true and the amplifier shelv e s off. 126 M2 3 RRM 2 - 69 r r r r r r r r r r r r r r :. ·. ·.:,· f . r r r r r Q1 and Q2 are at all times properly biased due to the feedback path from emitter of Q2 to the base of Q1 through R5. The signal is passed on to Q3 which is a phase distortion correction stage. Considerable rotation of phase normally occurs in the overall process of recording and playing back tape. The situation is increasingly pronounced at shorter wavelengths. In copying tapes the effect is compounded. Q3 provides a very effective correction for such distortion through C5 and R 13. Note that the signal voltage at both the collector and emitter are identical but IBO degrees out of phase. For low frequencies C5 is a very high impedance, and R 13 feeds its signal directly to the base of Q4 which presents a high impedance since it is an emitter follower. At very high frequencies, on the other hand, C5 has a very low impedance and consequently it feeds its signal to Q4 at a phase displacement of 1BO from that of R13. At intermediate frequencies the vector sum of the R13 and C5 signals result in a signal at Q4 of some intermediate phase angle between these extremes, but the amplitude remains constant which is most essential. 0 Emitter follower Q4 feeds the signal to the gain controls R15 and R27. The output of R15 is applied to the deemphasis network R16, R17, C7, RIB, R19, and CB. Its output at C9 represents an equalization characteristic which is exactly the inverse of the preemphasis curve generated in the Dynatrack record board. In some cases C7 and CB are trimmed by small parallel capacitors. The signal from C9 is applied to a double emitter follower circuit, Q5 and Q6. This is to provide a conveniently low impedance at the output signal terminal 16, yet provide a very high impedance to the output of the equalizer at C9. Switch S2 removes the deemphasis equalizer from the circuit so that playback from a standard NAB alignment tape may be used for aligning the adjustable equalizers. It is then only necessary to operate S2 to insert the network in order to convert the board to Dynatrack equalization. Under normal low signal level conditions the preamplifier feeds directly through Q6 to the output. The output of the second or H track is applied at terminal 17. R50 is a photo resistor unit. The lamp is normally dark so that resistance of the photo element is very high (approximately 100 megohms). When the lamp is lit, however, it drops to a very low value, (less than 500 ohms). When this happens the high or H track provides the signal source and short circuits the high impedance junction of RIB, RI9. The lamp in the photo resistor unit,R50, is controlled indirectly by the signal level at the output of Q4, as follows: R27, TRIG., provides an adjustable amount of this signal to a transistor amplifier QB. Q9 is normally conductive in the absence of an input signal from R32 because its base is connected to the positive bus through R33. This causes the collector to be at a low voltage due to voltage drop across R34, and since the base of Q10 is direct coupled through R36, QIO is cut off. M23 RRM 2-69 127 If the peak exc ursion of the audio input signal exceeds a certain criticaL vaLue in the negative-going direction, th e 09 collector current is reduced. The collector poten tial rises , bringing OLO int o conduction. This causes the eITlitter potentiaLs to ris e further cutting off 09 and driving OLO int o saturation. There are thus two stabLe states for the collector of OLO. When the peak signaL aITlpLitude drops beLow a certain criticaL vaLue, OLO c uts off by the saITle process in reverse. 09 and OLO constitute a Sc hITlitt trigge r . In its norITlaL nonconductive condition 010 applies zero voLts potentiaL through R39 as ITleasur e d froITl base to eITlitter of 011. 011 is therefore nonconductive and the junction of CIS and R40 is at zero voLts potentiaL above ground. Whenever 010 is r end ere d conductive, and this can b e just a few degrees of a single cycle of any frequency up to 15 kHz, 011 is also rendered conductive. It iITlITlediateLy charges ClS. This capacitor does not los e its charge for about 5 ITlilliseconds through R41. The instant a charge is placed on CIS by conduction of 011 this above ground potential is appLi e d through R42 to the base of 012 bringing it into fuLl conduction. Whe n CIS is discharged, 012 is fully cut off. 012 is a high voLtage transistor op e rating froITl the 120 V DC suppLy at terITlinaL 15. When 012 is conductive the 120V supp l y furnishes c urrent through R4S and RSI to the neon LaITlp in the photo resistor unit in paralleL with R43. The LaITlp lights and causes the resistance of the photo r es is t or eleITlent to drop, perITlittin g the signaL froITl the H track, terITlinal 17, to b e applied to 05 instead of th e signaL froITl the L track since it shorts out the Latter . When Ol2 is cut off the collector potentiaL ris e s, perITlitting the pilot indicator LaITlp DSl to light. R43 causes the voltage across the laITlp in the photo resistor unit to drop we ll below its extinction voltage so the r esistance of the photo resistor rises to its dark value. When 011 becoITles conductive, CIS charges very rapidLy causing the LaITlp in th e photo resistor unit to Light within one ITlilLisecond after a signaL cOITlponent aITlp li tude exceeds the triggering Leve l. When 011 cuts off , however, CIS discharges over a considerable period of tiITl e ass uring that the LaITlp is not extinguished until th e succeeding cycle of signaL is obse rved to see if it is of sufficient aITlpLitude to again trigg e r the SchITlitt and keep the LaITlp lit. The Lowest frequency of interest in this r egard is about 400 Hz. Sl has three positions. In the center AUTO position the photo resistor is controlled autoITlati ca lly by the in coITl ing audio signal. In the HI position the base of Oll is connected to ground, so as to keep DSI off at all tiITles and the LaITlp in RSO on. In the LO position the base of 011 is co nnected to the positive suppLy, cu tti ng it off, turning on DSI and cutting off the lamp in RSO. 07 is a r eg ulator transistor intended to drop the input bus voltage by a fixed aITlount deterITlined by thl' values of R2S and R26, and to fiLter out any powe r suppLy rippLe by ITleans of C18 and C1 7. 128 M23 RRM 2 -69 r Meter and Power Supply Assembly (5) (See Figure 40) r r r r r L r l This unit contains the power transformer, a large filter capacitor, the VU meter, and a regulator circuit to assure that the output of +28 volts is maintained within a few millivolts under varying load conditions. Line voltage is applied to terminals 5 and 20, through the 1/2 ampere fuse Fl to the power transformer. The transformer secondary feeds a bridge rectifier CRl, CR2, CR3, and CR4 charging Cl through surge Limiting resistor Rl. QI is the power regulator transistor. R2 has a very low resistance and is used to monitor the load current. Its action will be described below. The regula ted dc output is taken from terminal 12, positive, and terminal 9, negative and ground. R7 and R8 are in series across the output terminals. Any variation in output voltage is therefore monitored by the base of Q3 which amplifies the base voltage variation because the emitter is kept at constant potential by zener diode CR6. The amplified variation is applied to the base of Q2 where it is further amplified and applied to the base of 01, thus compensating for the initial variation. If the power supply is loaded too heavily, so as to possibly damage Ql, the voltage drop across R2 causes a potential difference to occur across the base and emitter of 04. However, this is only after the drop across R2 is sufficient to exceed the contact potential of CRS, and CRS becomes conductive. Thus this circuit is inactive until a definite Load is exceeded. When Q4 becomes conductive, it takes control of the regulator circuit and causes the output voltage to drop with increasing load, thus protecting the control transistor Ql. Terminals are provided for R9 which may be jumpered out for maximum brilliance of the meter Lamps. RIO is a similar resistor or jumper for the lamps of an external remote meter. Resistors R 11, R 12, and R 13 are part of the A-B transfer circuit, other components of which are wired into the main assembly. NAB Erase Coupler (3N) (See Figure 37) This is a very simple board which connects the erase power amplifier on board 1 to the erase head and permits monitoring erase current. When switching to Dynatrack this board is replaced by the Dynatrack record amplifier which fits into the same slot and rearranges connections so that proper bia s is supplied to the L track. When this board is used, 120 kHz power from the erase amplifier is supplied to terminal 20. Cl forms a resonant circuit with the erase head to provide maximum head current. Rl is the feedback resistor controlling the overaLL erase amplifier drive. Terminal 17 is connected to the head return which is isolated from ground by 10 ohms in the erase amplifier chassis. This point and the test point connected to it becomes a monitoring point for 120 kHz current. R3 permits erase meter calibration. r r M23 RRM 2-69 129/130 SCHEMATICS r r r r This section contains schematics of the tape transport, electronics assembly, and each of the circuit boards used for NAB and Dynatrack operation. r r r r r r r r r r r r r M23 RRM 2-69 131/132 This 3M M23 manual was "scanned by the klettster" as a GIFT* to those who have these machines and want to keep them operational The 3M M23 was the first 3M iso-loop tape recorder for professional use 3M M23 machines were around 45 years old at the time this scan was made enjoy this... keep the reels turning *if some opportunist charges you money for this pdf he's making money from no investment other than his time, trolling around on the interweb finding this and other docs, downloading and flipping multiple copies for cash - like a money machine... whereas the klettster has several hours and36 in costs (for scanning the larger pages) invested in to
this... and is asking nothing... other than that you use and enjoy... maybe I am the idiot
and the trolling pdf reseller is the genius...
I'll leave that for others to debate.
