3Rio Rancho, NM - USADigital-hybrid, Frequency Agile Handheld TransmitterINTRODUCTIONThank you for selecting the Lectrosonics UT400 hand-held wireless transmitter. TheUT combines over 80 years of engineering experience with the very latest componentsin a design that addresses the most demanding professional applications.The design of the UT400 was the direct result of numerous conversations with users,staging and touring companies and dealers across the US. The specific concerns andneeds brought up in these conversations led directly to the development of the opera-tional features offered on the UT400. Two hundred fifty six frequencies are userselectable in 100kHz steps to alleviate interference problems in travelling venuesThe UT400 is an integral microphone/transmitter with an internal antenna. The antennais a dipole type utilizing the two printed circuit boards as the elements. The housing iscomposed of durable PVC, machined to a natural, comfortable shape. Internal me-chanical parts are machined aluminum and brass.Only the UT400 transmitters are covered in this manual. Companion receivers arecovered in separate manuals. The UT400 will operate with any 100 Series, 200 Seriesand 400 Series Lectrosonics receiver in the same frequency group.
4UT400LECTROSONICS, INC.GENERAL TECHNICAL DESCRIPTIONGENERALThe 400 system uses 75kHz wide deviation for an extremely high signal to noise ratio. The switching power suppliesprovide constant voltages to the transmitter circuits from the beginning (9.3 Volts) to the end (5.5 Volts) of battery life.The input amplifier uses an ultra low noise op amp for quiet operation. It is gain controlled with a wide range dualenvelope input compressor which cleanly limits input signal peaks over 30dB above full modulation.DIGITAL HYBRID TECHNOLOGYAll wireless links suffer from channel noise to some degree, and all wireless microphone systems seek to minimize theimpact of that noise on the desired signal. Conventional analog systems use compandors for enhanced dynamic range,at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sendingthe audio information in digital form, at the cost of some combination of power, bandwidth and resistance to interfer-ence.The Lectrosonics Digital Hybrid system overcomes channel noise in a dramatically new way, digitally encoding theaudio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FMwireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique whichcan be accomplished only in the digital domain, even though the inputs and outputs are analog signals. (As of thiswriting, the patent is still pending, so we cannot reveal detailed information about the algorithm at this time.)Channel noise still has an impact on received signal quality and will eventually overwhelm the receiver. The DigitalHybrid simply encodes the signal to use a noisy channel as efficiently and robustly as possible, yielding audio perfor-mance that rivals that of wholly digital systems, without the power and bandwidth problems inherent in digital transmis-sion. As always, these advantages come at a cost. The Digital Hybrid system requires fairly intensive digitalprocessing in both the transmitter and the receiver. These processors cost money, take up space and consume power.The Digital Hybrid system also requires that the underlying RF link be of excellent quality, with better frequency re-sponse and distortion characteristics than that required by conventional systems.Because it uses an analog FM link, the Digital Hybrid enjoys all the benefits of conventional FM wireless systems,such as excellent range, efficient use of RF spectrum, and long battery life. However, unlike conventional FM sys-tems, the Digital Hybrid has done away with the analog compandor and its artifacts.Phase Locked LoopVoltageControlledOscillatorFreqSwitches11001001A-DConverterDigital Signal Processor11001001D-AConverterShuntLimiterBicolorModulationLEDsMicroprocessor9VBatterySwitchingPowerSupply+3.3v+1.8v+9v-3vAudioEncodedAudio +Pilot Tone11.3 MHzReferenceBicolorPowerLEDAudioLevelInputAmpFinalAmplifier50 IsolatorPreampMicElementPreampLevelTone
5Rio Rancho, NM - USADigital-hybrid, Frequency Agile Handheld TransmitterNO PRE-EMPHASIS/DE-EMPHASISThe signal to noise ratio of the 400 system is high enough to preclude the need for conventional pre-emphasis (HFboost) in the transmitter and de-emphasis (HF roll off) in the receiver. Pre-emphasis and de-emphasis in an FM radiosystem usually provides about a 10dB improvement in the signal to noise ratio of the system, but the high frequencyboost in the transmitter must be removed in a purely complementary manner or else the frequency response of theoriginal audio signal will be altered.Pre-emphasis can also cause distortion in the receiver. As this signal is passed through the IF filters in the receiver,distortion can be produced, most noticeably at full modulation. De-emphasis cannot be applied until the signal isconverted into audio, so there is no way around this problem short of eliminating pre-emphasis altogether. Neither ofthese problems occur in the 400 systemPILOT TONE SQUELCHThe 400 system utilizes one of 256 different ultrasonic tones between 25 and 32 kHz, that modulate the carrier tooperate the receiver squelch. The pilot tone frequency is chosen according to which of the 256 channels has beenselected by the frequency switch setting. The basic benefit of the pilot tone squelch system is that the receiver willremain muted until it receives the pilot tone from the matching transmitter, even if a strong RF signal is present on thecarrier frequency of the system. The UM400 extends this concept even further by insuring that all transmitters in asystem have different pilot tone frequencies so that even spurious RF from the wrong transmitters can’t open thereceiver squelch.WIDE-BAND DEVIATION±75kHz deviation improves the capture ratio, signal to noise ratio and AM rejection of a wireless system dramatically,compared to the more commonly used ±15kHz deviation.LONG BATTERY LIFESwitching power supplies throughout the design allow over 5 hours of operation using a single 9 Volt alkaline battery. (A9V lithium battery will provide over 14 hours of operation.) The battery contacts are spring loaded to prevent “rattle” asthe unit is handled.FREQUENCY AGILITYThe transmitter section uses a synthesized, frequency selectable main oscillator. The frequency is extremely stableover a wide temperature range and over time.Two rotary switches, located under the battery door, provide 256 frequencies in 100kHz steps over a 25.5MHz range.This alleviates carrier interference problems in mobile or traveling applications.ANTENNAThe high output antenna utilizes the lower half of the printed circuit boards as one radiating element, with the upper halfof the PC boards and the mic capsule as the other half of the dipole configuration. This allows the mic to be held in anyposition, since the user’s hands have little or no effect on the radiated power.MICROPHONE ELEMENTThe UT400 includes the Lectrosonics VariMic mic element. The VariMic is an cardioid condenser back electret micro-phone that is adapted for the unique circumstances of wireless microphones. The problems it solves are dynamicrange, handling noise and low frequency noise (rumble or wind).In the VariMic, an unusual pumped source FET circuit increases the usable dynamic range 12dB and greatly reducesdistortion, just as if the FET were being supplied with 48 Volts. In addition, a unique 16 position sensitivity control at theelement itself can adjust the sensitivity in 15 steps over a 15 dB range. This is in addition to the normal gain control inthe wireless microphone. The result is the widest dynamic range of any condenser mic in a wireless microphone.The VariMic has a three point damped rubber suspension to reduce high frequency handling noise and a generous sizedwindscreen to keep wind noise and breath pops away from the microphone.

The pilot tonemuting system prevents “thumps” or transients fromoccurring even when the switch is turned off or onabruptly,The Power LED glows green when the battery is good andthe ON/OFF switch is ON. The lamp will glow red as thebattery voltage drops and finally flashes when there isabout 30 minutes of operation left with the recommendedalkaline battery. The lamp will flash red when there areonly a few minutes of life left. A NiMh battery will givelittle or no warning when it is depleted. If you wish to useNiMh batteries in the UM400, we recommend trying fullycharged batteries in the unit, noting the length of time thatthe batteries will run the unit and in the future use some-what less than that time to determine when the batteryneeds to be replaced. A weak battery will sometimes lightthe POWER LED to the “good” green indication immedi-ately after being put in the unit, but will soon discharge tothe point where the LED will go red or shut down, just likea flashlight with “dead” batteries. If the lamp fails to light,the battery should be replaced.FREQUENCY ADJUSTTwo rotary switches (located under the battery door) adjustthe center frequency of the carrier. The Coarse adjust-ment adjusts the frequency in 1.6 MHz steps and the finein 100 kHz steps. Each transmitter is factory aligned atthe center of its operating range for uniform operationacross the entire band. The default position of the fre-quency select switches is in the center of the transmitterrange.MOD LEVEL LEDsThese LEDs (located under the battery door) indicate theproper setting of the MIC LEVEL control. There are twobicolor modulation LEDs that can light either red or green. “-20dB level” One modulation LED glows green and the transmitter is 20 dB below full modulation.“-10 dB level” Both modulation LEDs glow green and the transmitter is close to full modulation.“+0 dB level” The -20 LED glows red and the -10 LED glows green. The transmitter is in slight limiting and is fullymodulated. This is probably desirable. See the discussion below under Input Limiter.“+10 dB level” Both LEDs are red. The transmitter is in limiting and you may want to reduce the transmitter audiogain. See the discussion below under Input Limiter.
7Rio Rancho, NM - USADigital-hybrid, Frequency Agile Handheld TransmitterINPUT LIMITERThe 400 series transmitters employ a digitally-controlled analog audio limiter just before the analog-to-digital converter.The limiter has a range of more than 30dB for excellent overload protection. A dual release envelope makes the limiteracoustically transparent while maintaining low distortion. It can be thought of as two limiters in series, connected as afast attack and release limiter followed by a slow attack and release limiter. The limiter recovers quickly from brieftransients, so that its action is hidden from the listener, but recovers slowly from sustained high levels, to both keepaudio distortion low and preserve short term dynamic changes.The audio level LEDs indicate limiter activity. The first red LED indicates that the limiter is active and that the transmit-ter is fully modulated (audio level is between +0 and +10 dB). The second red LED indicates that the level is 10dB ormore into limiting. Occasional forays into the red are desirable for most applications, since the distortion introduced bythe limiter is so minimal, and full modulation is thus assured. We strongly recommend setting the gain of the transmit-ter high enough so that the first red LED occasionally lights. Generally speaking, some limiting is desirable in normal operation to improve the signal to noise ratio of the system.The limiting action is not audible and does not create distortion. A highly trained ear would hear only the compressionof the peaks in the audio signal, which is desirable with most recorders and many sound reinforcement systems.AUDIO LEVELThis knob (located under the battery door) is operated while speaking or singing into the transmitter to adjust the audiogain of the transmitter for the correct amount of modulation. The LEDs located next to it indicate the modulation levelas the gain is adjusted. See the Operating Instructions section for details on this very important adjustment.VARIMIC CONTROLSCaution - Due to the high RF levels surrounding the transmitter, the sound of the Varimic capsule may be temporarilyaffected if the metal windscreen is not in place. Always make the final decision about sound balance and quality withthe windscreen in place.The VariMic head includes adjustments for Bass, Midrange and Treble response. There is also an attenuation adjust-ment to provide up to 15dB of additional headroom if needed.BASS / MID / TREBLE (LO / MID / HI)The bass and treble controls will boost/cut by up to ap-proximately 8dB while the Mid control will boost/cut up toabout 6dB. These controls operate as standard tonecontrols. Counter-clockwise will reduce the response in thatband and clockwise will provide a true boost. Thesecontrols can be accessed by removing the windscreen. Toremove the windscreen, grasp the body of the transmitter inone hand and the windscreen in the other hand. Carefullyunscrew the wind-screen counter-clockwise until it comesoff then carefully slide the windscreen past the mic ele-ment.• Set flat, the mic capsule is very wide range and sounds alot like a large competitor’s top line condenser mic.• Bass cut gives a dry but highly intelligible sound. Crisp.• Bass boost “fattens” the sound but is very listenable.Does not get midbass boomy.Bass (LO) Mid (MID) Treble (HI)
8UT400LECTROSONICS, INC.+100dB-10 10Hz 100Hz 1KHz 10KHz+5-5UT200 Bass/Midrange/Treble Boost/Cut• Midrange cut sounds very smooth. Almost a “crooner”quality. A sweet sound.• Midrange boost is likely to be useful in a system that ismidrange shy.• Treble cut has a “mellow” sound. The capsule has a solidhigh end so a little cut does not ruin the response.• Treble boost might be fine on some sound systems. Thesound doesn’t get harsh (showing that the response wassmooth) but sibilants are a little too much. Should beused in moderation.PREAMP LEVEL CONTROLThe VariMic head includes an attenuator to provide anadditional 15dB of headroom when needed. The attenuatorshould only be used when the normal Mic Level pot isalready turned down as far as it will go and the signalthrough the mic is still too hot. The attenuator control is a16-position switch marked 0 through F. “F” is minimumattenuation or the highest signal level. “0” is maximumattenuation or the lowest signal level. For the maximumamount of headroom, set the switch to “0.”Note: The attenuator should not be used as a levelcontrol. The Audio Level control inside the batterycompartment is the main level control. Adjust theattenuator only when the Audio Level control isturned completely down and more headroom is stillneeded. Be sure to set the attenuator back to itsoriginal setting for normal operation.BASS FILTERIn addition to the tone controls, theUT400 also has a built in bass filter. Thisfilter is fixed and cannot be adjusted ordefeated. Low frequency noise is muchmore of a problem with wireless micro-phones than with conventional micro-phones. With a regular mic, low fre-quency wind noise, breath thumps orhandling rumble can be filtered out at thecontrol board before the noise causesproblems with the following electronics orspeaker systems. But with a wirelessmicrophone, the electronics that will beoverdriven are right in the wirelessmicrophone. Filtering at the control boardis much too late. To solve this problem,the VariMic has a low frequency filter thatis so sharp that it can remove low frequency noise without affecting any wanted vocals. It consists of a 36 dB peroctave filter circuit to sharply remove low frequency noise below 75 Hz without affecting vocal fundamentals. Thelowest operatic bass voice fundamental is 82 Hz.200dB-20-40-6010Hz 100Hz 1KHz 10KHzVariMic Low Frequency Roll-off Filter-3dB @ 71Hz-20dB @ 50HzPreamp Level Control

Note that the locking ring is in the closed position for this procedure.Ring will sit flush in the closed position.Pull Ring OutwardBATTERY INSTALLATIONThe transmitter is powered by a standard alkaline or lithium 9 Volt battery. It is important that you use ONLY ALKA-LINE or LITHIUM batteries for reliable operation. Alkaline batteries will provide about 4 hours of operation while thelithium batteries will operate the transmitter for over 14 hours. The battery status lamp will function normally only withalkaline or lithium batteries. Standard zinc-carbon batteries marked “heavy duty” or “long-lasting” are not adequate.They will provide only about 30 minutes of operation. Similarly, nicad rechargeable batteries only provide about 1 hourof operation, and will run down quite abruptly.The battery compartment is located in the lower section of the transmitter, between the two printed circuit boards. Toinstall a fresh battery, follow the steps illustrated below.Look inside the battery compartment when the cover is off and take note of the two differently sized holes in thebattery contact pad. Insert the battery so that the large hole in the battery contact pad will line up with the largecontact on the battery when it is installed. The spring-loaded plunger in the bottom of the compartment (opposite thecontact pad) secures the battery in place.The battery status is indicated by an LED on the bottom panel. The LED will glow brightly when the battery is good andwill dim as the battery condition deteriorates. The LED is green with a new battery. The battery status is also displayedon the Information Display on the front panel of the receiver. See the receiver manual for further details.Note: It is possible to insert the battery backwards and still be able to close the battery door. No damage will occur butthe transmitter will not operate in this condition.
10UT400LECTROSONICS, INC.OPERATING INSTRUCTIONSSELECTING THE OPERATING MODEAll units with serial number 601 and up are capable of working with Lectrosonics 100 series analog , 200 series analog,400 series digital hybrid or some other analog wireless receivers (contact the factory for details). The transmitter mustbe set to the operating mode of the matching receiver, which is easily done using only the supplied screwdriver and abattery.NOTE: the unit is supplied from the factory as a 400 series transmitter1) Make certain a good battery is installed.2) Power down the transmitter.3) With a small screwdriver (included with your unit), set the frequency change switches to CC. (for Change, Change).4) Power up the unit briefly – just a couple of seconds (just watch for the LED’s to light up) and then turn it off.5) Change the switches to one of the following settings:• To set Lectrosonics 100 mode: set switches to 1,1• To set Lectrosonics 200 mode: set switches to 2,2• To set mode 3: set switches to 3,3* (contact the factory for details)• To set Lectro digital hybrid (400) mode: set switches to 4,46) Turn the unit on, wait just a couple of seconds and turn off again.7) Change the switches to 0,0.8) Power up the unit – you have now changed the operation mode for the unit.The LEDS will blink at powerup to indicate the selected operating mode. Immediately after powering up, all LEDSwill blink together red, then green, followed by the audio level LEDs (-20 and -10) blinking to indicate the mode.The –20 and –10 LEDs will blink:• Once for 100 mode• Two times for 200 mode• Three times for some other receivers• Four times for 400 modeAt powerup the transmitter will confirm the current operating mode with the number of blinks listed here. The settingwill remain the same until you reset it with the procedure listed above.ADJUSTING THE GAIN1) Install a fresh battery. Leave the battery cover off for further adjustment.2) On the bottom panel, move the “A” (audio) switch to “OFF” (away from the LED) and the “P” (power) switch to ON(toward the LED) in that order. Observe that the battery status LED is brightly lit. If the LED is dim, replace thebattery.3) Hold the microphone in the same position that it will be used in actual operation.4) While speaking or singing at the same voice level that will actually be used, observe the MODULATION LEDs.Adjust the AUDIO LEVEL control knob until the LEDs begin to light. At too low a setting neither LED will light asyou speak. Gradually, turn the gain up until the –20 dB LED lights green and then the -10 dB lights green. Westrongly recommend setting the gain of the transmitter even higher so that the first red LED occasionally lights.If you find that the AUDIO LEVEL control is set to minimum and the LIMIT LED is still on often, then adjust theattenuator. This control is located under the windscreen. Unscrew the windscreen and carefully lift it off the top ofthe unit. See the VERIMIC CONTROLS section for these adjustments. If you need to change these controls, besure to repeat the gain adjustment procedure beginning at step 3.5) Once the gain has been adjusted, the audio system audio can be turned on to make level adjustments in the mainaudio system.
11Rio Rancho, NM - USADigital-hybrid, Frequency Agile Handheld TransmitterOPERATING NOTESThe AUDIO LEVEL control knob should not be used to control the volume of your sound system or recorder levels.This gain adjustment matches the transmitter gain with the user’s voice level and microphone positioning.If the audio level is too high — both red LEDs will light frequently or stay lit. This condition may reduce the dynamicrange of the audio signal.If the audio level is too low — neither LED will light, or only the -20 LED will light green. This condition may cause hissand noise in the audio.Different voices will usually require different settings of the AUDIO LEVEL control, so check this adjustment as eachnew person uses the system. If several different people will be using the transmitter and there is not time to make theadjustment for each individual, adjust it for the loudest voice.ADJUSTING THE TRANSMITTER FREQUENCYIf you are experiencing interference from another signal on your frequency, youmay want to change the operating frequency of your system. The switch nearestto the mic element changes the operating frequency by 100 kHz per step (Fine)and the switch furthest from the mic element changes it 1.6 MHz per step(Coarse). If you are experiencing interference, change the operating frequency ofthe receiver to find a clear channel, then set the transmitter to match.Some receiver models will indicate the correct transmitter switch settings on thereceiver control panel.89ABCDEF0123456789ABCDEF01234567Coarse Fine
