CARVIN ENGINEERING DATA RX800, RX1200, RX1200R MIXERS OPERATING MANUAL DISTORTION-FREE LIMITERS The purpose of a limiter is to hold down peaks so the amp won’t distort even with extra hot input signals (this protects your expensive speakers). In addition, limiters can increase your amp’s average output by 3 db or more. Part of Carvin’s design uses the more expensive, distortion-free linear “opto isolators”. Unlike amps that use FET controlled limiters which can inject small amounts of distortion, our limiters keep your sound pure and uncolored! RX1200 in Road Warrior Case CONGRATULATIONS on your purchase of Carvin’s RX800, RX1200 or RX1200R mixer! The "R" version is a non-powered rack model designed for use with your own power amps while the RX800 and RX1200 models include built-in high power amplifiers for direct hook-up to your speakers. Please read this manual carefully to take advantage of the many features of your mixer. SUPERB SOUND is derived from the extremely low distortion, high "Headroom" design. A state-of-the art, low noise, high headroom, balanced XLR preamp for each channel features a common mode rejection of better than 78 dB, which means that any possible noise that may come over your cables is virtually eliminated. Even the balanced XLR output connectors guard your system from cable noise for professional recordings or external power amp connections. Distortion is nearly non-existent with THD below .1%, which guarantees the purity of your sound. Hear the difference - your sound will not seem "sterile" or "processed". It will be dynamically open and transparent just like it was meant to be! LIGHT WEIGHT and EASY TO USE controls are logically laid out, making the RX Series simple to use - quick adjustments can be made easily. Its compact size and weight of 30 lbs. makes it the lightest, most powerful mixer of its kind. No other competitor in the industry offers a higher performance to weight ratio! 4 HIGH CURRENT AMPLIFIERS deliver 300 watts RMS each. A total of 600 watts is delivered to your main speakers, plus two 300 watt amps to drive your stage monitors for a total of 1200 watts. Speaker outputs feature both Twist-Lok and 1/4” jacks, delivering full power into 4 ohms, making these mixers more powerful than most amplifiers rated at 2 ohms. A peak indicator for every amp and a protect LED gives you a visual monitor. A HIGH CURRENT POWER SUPPLY is provided by a beefy toroid transformer to assure continuous high amperage DC voltage to all three power amplifiers, eliminating "overload" or shutdown. 20,000 mfd capacitors offer a large power reservoir for bass thumping output. The RX1200R features a 125k Hz switching power supply for operating your mixer at any voltage from 90 VAC to 240VAC. Like a laptop computer, you can go anywhere in the world and not worry about power adapters. 2 INDEPENDENT 24-Bit STEREO DSP EFFECTS allow you to independently assign each channel to your choice of simultaneous effects. You can dedicate chorus/rev to the acoustic guitar channel and reverb to the vocals, etc. Both effects are assignable to your stage monitors so you can hear yourself with full effects. The effects processors feature 256 effects each, including reverbs, choruses, flanging and echoes, with parameters fully adjustable for; damping, decay, depth, speed, regeneration and time. ACTIVE 3 BAND CHANNEL EQ provides easy adjustment for the tone you want. The LO frequency controls start at 20 Hz and continue through 80 Hz for a solid non-flabby bass. A simple adjustment with the MID control gives you the best sound for vocals or guitar in the very important 750Hz frequency range. The 11.5k Hz HI treble control adds sparkle to your top-end without adding harshness. Both the LO and HI are "shelving", which means they are effective from 20Hz up to 20k Hz. FOUR 7 BAND EQUALIZERS provide precise adjustments to fine tune your overall sound and to help control feedback. Unlike one stereo graphic equalizer, four independent 7 bands give you total control over each power amp output. ENGINEERED TO LAST Every RX Series mixer is housed in a rugged reinforced steel rackmountable chassis. Continuous full power is assured from a 370 sq inch, high-grade 6063-T5-aluminum heat sink cooled by a quiet variable speed fan. You’ll never have to worry about protect or power reduction modes. Hidden deep in the heart of these mixers is the “SMT” Surface Mount Technology construction that utilizes surface mounted components to prevent parts from shaking or vibrating loose. Sealed controls and switches guard against the outside elements while heavyduty connectors provide a positive connection to your cables. Fire retardant FR-4 military spec circuit boards feature double-sided copper construction to guard against noise and radio frequencies (RF). Precision 1% tolerances guarantee that your settings will be accurate every time. The RX Series is professionally made in the USA for years of service!

PETERSEN 14JUN05 FROM FRONT PANEL INSERT CLIP LIMITER POWER AMP PROTECTION RELAY SPEAKER OUTPUTS RX800, RX1200, RX1200R CONTROLS QUICK START UP If you’re like most new owners, you’re probably in a hurry to plug your mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and the unit turned off, complete the following procedures: A. CONNECTING AC POWER TO YOUR MIXER • Be sure to plug your mixer into the proper voltage for your country, either 120V-60Hz or 240V-50Hz. The RX1200R accepts both voltages listed. • Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer. B. CONNECTING INPUTS TO YOUR MIXER • For balanced microphones, use a shielded cable and plug into the XLR MIC inputs. • For high output devices like instruments & keyboards, plug into the LINE input jacks using a shielded cable. Be sure the LINE/INS switch is in the “OUT” position. C. TURNING YOUR MIXER ON • Set all channel and master LEVEL controls to their OFF positions • Set all HI, MID, and BASS controls and the graphic equalizers to their center “flat - no boost or cut” position. • Adjust all channel “PAN” controls to their center position. • Connect your speakers and monitors at the rear panel. • Turn the mixer on by the rear POWER SWITCH and watch for the front POWER LED to come on. Your mixer is now ready to operate by turning the levels up. dual effects processors and to the EFF 1 and EFF 2 SND jacks. The effects controls are post-channel level and automatically track the channel’s LEVEL & tone controls. Reduce these levels if PEAK LEDs are flashing on the effects processors. The remaining input channels (1-7, or 1-11) are turned OFF eliminating feedback or other unwanted sounds from open mics during breaks or changes. The LED indicates the MUSIC BREAK is ON. The internal effects are also muted. 8. MON 1 & MON 2 CONTROLS The TAPE IN level adjusts the input to your mixer from the RCA TAPE IN jacks to the MAIN L/R and MONITOR outputs. The TAPE OUT level sends the MAIN L/R signal (pre graphic EQ) to the TAPE OUT RCA jacks for recording. If the TAPE OUT is being used to record, make sure the TAPE IN control is turned OFF to avoid feedback from the recorder. The MON 1 and MON 2 level controls adjust the volume of the channel going to the monitor amps. The monitor level control is a pre-channel level control. This means it is unaffected by adjustments from the channel level. The purpose for this is the monitor mix adjustments can be made without disturbing the main mix. 9. CHANNEL TONE CONTROLS Each channel features active 3-band tone controls LO, MID, and HI. These function as boost (clockwise) or cut (counter-clockwise) controls. The center 0 is the “flat” or no effect position. The LO and HI controls are shelving type with corner frequencies at 80Hz and 11.5k Hz respectively. The MID control is a band pass type centered at 750Hz. 13. TAPE IN AND TAPE OUT LEVELS 14. LEFT & RIGHT XLR OUTPUTS The LEFT and RIGHT balanced XLR line outputs are the same signals that feed the internal AMPS 1&2. Use these outputs for additional power amps or recording gear. 15. MONITOR 1& 2 OUTPUTS The MONITOR 1 - 2 line outputs are the same signals that feed the internal MONITOR AMPS 3 & 4. Use these outputs for additional power amps or recording gear. 9 MIC CHANNEL FEATURES 1. LINE INPUT/INSERT JACK The LINE input is a 1/4” phone jack designed for balanced or unbalanced line or instruments. Examples of these inputs would be guitar, keyboard or CD player. The line input can be used at the same time the mic input is being used. This jack becomes an insert when the INSERT switch is pushed “IN”. 8 7 2. INSERT SWITCH This switch changes the function of the channel’s 1/4” jack. The “OUT” position is for normal LINE level inputs. Pressing the INSERT switch “IN” changes the jack into an INSERT with SEND and RETURN. This allows you to place effects on the channel after the GAIN control for lowest noise. To insert effects (such as a compressor, etc.) use a 1/4” stereo splitter adapter (like Carvin AP1). Connections are TIP-SEND and RING-RETURN. 6 5 4 3. XLR MICROPHONE INPUT The XLR MIC input is designed for balanced low impedance microphone and DIRECT OUT signals. The high performance mic preamps do a superb job of noise reduction, but to get the lowest noise adjust the GAIN control properly (see #5). Note: Make sure the phantom power is switched off (discharged) for at least 5 seconds before connecting or disconnecting microphones to the mixer. 4. CHANNEL LEVEL CONTROL The LEVEL control adjusts the volume of the channel before going to the PAN control. Here is where the individual channel volumes are adjusted to make up the overall mix at the MAIN L/R outputs. Start with the LEVEL set between 3-5. 5. GAIN CONTROL / PK LED The GAIN control varies the input level on both the LINE and MIC input jacks by 40dB. With a LOUD input signal, (loud vocal, hard hits on drums, etc...) turn up the GAIN control until a strong signal is present. If the “PK” LED shows or distortion is heard, the input stage is being overdriven. Lower the GAIN control until the LED does not light. 6. CHANNEL PAN CONTROL The PAN control sends the channel signal to the MAIN L/R outputs. If stereo placement is needed, turn the PAN control toward the LEFT or RIGHT position. 7. EFF 1 & EFF 2 CONTROLS The EFF 1 and EFF 2 controls adjust the levels sent to the 3 1 2 MASTER SECTION FEATURES 10. MAIN L/R LEVEL (AMPS 1&2) The MAIN L/R control is the master volume control for all channels. The MAIN L/R signals are sent to GRAPHIC EQs 1&2 that feed the AMPS 1&2, the LEFT and RIGHT XLR output jacks, and the MONO (SUB) output jack. 16. MONO (SUB) OUTPUT The MONO (SUB) output combines the MAIN L/R output signals that feed the internal AMPS 1&2. Use this output for additional power amps or amplified subwoofer. 17. SUB X-OVER SWITCH The SUB XOVER (crossover) switch removes all frequencies 11. MONITOR 1& MONITOR 2 LEVELS above 120Hz for connecting the MONO(SUB) output to an (AMPS 3&4) amplified subwoofer. This is a 3rd order (18db/oct.) filter. The MONITOR 1 and MONITOR 2 levels are sent to the GRAPHIC EQs which feed the MONITOR amps 3 & 4, and the MONITOR 1&2 output jacks. 12. MUSIC BREAK SWITCH/LED The MUSIC BREAK feature turns off all inputs except for the last channel (8 or 12) and the TAPE IN jacks. This is useful during breaks. This allows pre-recorded music to be played through the TAPE IN jacks. The channel 8 or 12 MIC and LINE inputs are left active for announcements or solo performers. 18. TAPE IN / OUT JACKS The L-R TAPE IN RCA inputs are ideal for connecting a CD or tape player. These TAPE IN jacks can also be used for returning another stereo effects processor or instrument (keyboard). The L-R TAPE OUT RCA jacks send the MAIN L/R signals (pre graphic EQ) for recording. If the TAPE OUT is being used to record, make sure the TAPE IN control is turned OFF to avoid feedback. 25. EFFECTS FOOT SWITCH JACK 20. EFF 1&2 SND JACKS The EFF 1&2 SND jacks can send signals to external processors. These are the same signals sent to the internal EFFECT 1 and EFFECT 2 processors. 21. AMP CLIP LED’s The amp CLIP LEDs indicate when the internal power amps are starting to distort (clip). Reduce the MAIN L/R, MONITOR 1 or MONITOR 2 master volumes to prevent distortion. 26. PHANTOM POWER SWITCH AND LED 22. PROTECT LED 19. DSP PROCESSORS Two 24-Bit processors provide a host of great sounding effects including Flange, Reverb, Echo, & Chorus. The channel EFF 1 & EFF 2 send controls deliver the signals to the dual processors. Note: Reduce these levels if the red PEAK LEDs are flashing on the processors. Turn up the MAIN controls to add effects to the MAIN L/R OUTPUTS. The MONITOR 1-2 levels control the amount of effects that go to the MONITOR outputs. The optional FS22 will remotely shut off EFFECTS 1 or 2. The mixer will “protect”, engaging relays to mute the speakers if: a) impedance is below 4Ω on any amplifier b) shorted speaker cables, or c) ventilation problems. If this LED comes on, shut the mixer OFF and check for cable problems, proper impedance and obstructed rear cooling vents. If you encounter an over-heat problem, leave the mixer ON allowing the fan to cool down the internal components. The mixer will auto-reset. 23. POWER LED The PHANTOM power switch turns on the microphone phantom power in the channel XLR jacks. This power is used for supplying a voltage to condenser microphones. The LED indicates the phantom power is turned on. The phantom power will not damage conventional dynamic microphones. Note: Make sure the phantom power is switched off before connecting or disconnecting microphones to the mixer. It is recommended to allow 5 seconds for the phantom power to discharge before making any microphone connections. The Power LED indicates when the mixer is powered on.

AMP PATCH INSERTS 10 13 20 26 23 22 21 25 14 15 16 EFFECT PARAMETERS Each of the four effects have variable parameters that are easily adjusted by the SELECT and the PARAMETER controls to get the desired effect. Each “SELECT” & “PARAMETER” is described below. Note: An audible noise will be heard while adjusting the effects. A) ECHO: Use SELECT to change the amount of regeneration (number of repeats). The PARAMETER control adjusts the delay time between the original signal and the echo. B) REVERB: SELECT the amount of presence (high frequencies) in the reverb. The PARAMETER control adjusts decay. C) CHORUS: SELECT the amount of reverb with your chorus. The PARAMETER control adjusts the depth. D) FLANGE: SELECT the amount of speed with your flange (phasing effect). The PARAMETER control adjusts depth. 17 18 24. ADJUSTING THE GRAPHIC EQUALIZER When the EQ sliders are in their center position, they do not affect the audio signal. When EQ sliders are raised or lowered from this position, they boost or cut respectively a narrow frequency band. To reduce feedback in the low frequency range, try lowering one of the 80 or 160 Hz sliders. High frequency feedback is usually reduced by lowering one of the 2k or 6k Hz sliders. To help prevent feedback, the main speakers should be placed in front and away from the microphones. For tone enhancement you may want to raise the 80, 160 (for deeper bass) and the 6k, 12k sliders (for crisper highs) forming a “smile” curve as shown. The AMP PATCH INSERT jacks offer full flexibility for mixer to amp signal routing. These jacks are T-R-S (Tip-Ring-Sleeve). Tip is the power amp input. Ring is the signal sent from the mixer. The builtin power amp limiters are post insert. Patching a compressor or equalizer between the mixer and the amp can be done by using a stereo insert cable (like Carvin’s AP1). Connect the RING signal to the INPUT of the external device, and the TIP signal from the OUTPUT of the device. Plugging in a standard 1/4” cable (mono) into the AMP PATCH INSERT jacks allows any external signal to be sent to the internal power amps. ***DO NOT USE A BALANCED SIGNAL CABLE*** 29. SPEAKER CONNECTIONS For the RX800 and RX1200, there are 4 groups of speaker jacks. Each group has one Twist-Lok (Speakon™) and two 1/4” outputs (wired in parallel). AMP 1 is for LEFT speakers. AMP 2 is for RIGHT speakers. AMP 3 is for MONITOR 1 speakers. AMP 4 is for MONITOR 2 speakers. NOTE: 4Ω MIN IMPEDANCE PER AMPLIFIER (Maximum one 4Ω or two 8Ω speakers per amp). MAKE ALL SPEAKER CONNECTIONS BEFORE TURNING THE MIXER ON .
