The Lectrosonics UM400a is a UHF bodypack transmitter for use with the UCR411 receiver. The transmitter features 256 user selectable UHF frequencies and digital hybrid signal transmission for optimum range while minimizing noise. Incoming audio signal is digitized at 24-bit resolution, eliminating the noise and artifacts associated with analog compandors.

The result is greater range with minimal noise. The improved TA5-male servo input is compatible with any microphone or cable featuring a TA5 connection. The input level is automatically matched, allowing use with low impedance mics, electret lavalier mics with positive or negative bias and line level devices. The receiver features a comprehensive LCD and low cut filter. A full 100mW output power is achieved on a single 9V battery.

Improved Servo Microphone Input
The UM400a delivers a significant improvement over the previous UM400 with its TA5-male servo input. The input level is automatically matched, allowing use with low impedance mics, electret lavalier mics with positive or negative bias and line level devices.
Digital Hybrid Transmitter
The UM400a transmitter features a DSP-based digital hybrid architecture. Incoming signal is digitized in 24-bit, eliminating noise associated with analog compandors. The result is greater range without noise.
Frequency Agile
The frequency agile UM400a transmitter features 256 selectable synthesized UHF frequencies to choose from. Rotary dials located on the side panel allow quick and easy switching.
High Output Power
Perhaps one of the major attributes to Lectrosonics components is the frequency output power. The UM400a boasts 100 mW of output power, rendering the unit virtually free from drop-outs.
Mic & Line Level Input
The input is designed to handle both mic and line level sources. A level dial conveniently adjusts impedance gain levels to accurately match different microphones and line sources.
Pristine Audio Quality
Flat frequency response and wide dynamic range provide superb audio fidelity. Dual-band compandor and low frequency roll-off, eliminate distortion and noise born at low frequencies.
Frequency Selection 256 frequencies in 100 kHz steps
RF Power Output 100 mW (nominal)
Pilot Tone 25 to 32 kHz; 5 kHz deviation
Frequency Stability ± 0.002%
Deviation ± 75 kHz (max)
Spurious Radiation 90 dB below carrier
Equivalent Input Noise -120 dBV (A-weighted)
Input Level Nominal 2 mV to 300 mV, before limiting. Greater than 1 V maximum, with limiting
Input Impedance Dynamic Mic: 300 ohms
Electret Lavaliere: Input is virtual ground with servo adjusted constant current bias
Line Level: 2.7 kOhms
Input Limiter Dual envelope "soft" limiter; greater than 30 dB range
Gain Control Range 43 dB; semi-log rotary control
Modulation Indicators Dual bicolor LEDs indicate modulation of -20, -10, 0, and +10 dB referenced to full modulation
Frequency Response 32 Hz to 20 kHz (+/-1 dB)
THD 0.2% (typical)
SNR SmartNR OFF: 103.5 (no limiting), 108.0 (w/limiting)
SmartNR NORMAL: 107.0 (no limiting), 111.5 (w/limiting)
SmartNR FULL: 108.5 (no limiting), 113.0(w/limiting)

(Note: The dual envelope "soft" limiter provides good handling of transients using variable attack and release time constants. Gradual onset of limiting in the design begins below full modulation, which reduces the measured figure for SNR without limiting by 4.5 dB)
Dynamic Range 125 dB (with full Tx limiting) low frequency roll-off (input)
Adjustment -18 dB/octave; adjustable from 35 to 150 Hz
Controls Two position "ON-OFF" power switch
Audio input gain knob
Low frequency roll-off pot on side panel
Two 16-position rotary switches adjust frequency
Audio Input Jack Switchcraft 5-pin locking (TA5F)
Antenna Detachable, flexible wire supplied
50 ohm port allows connection to test equipment
Battery Precision compartment auto-adjusts to accept any known 9 volt battery
Battery Life 5 hours (alkaline); 10 hours (lithium)
Emission Emission Designator: 180KF3E
Dimensions 3.17 x 2.48 x 0.84" (80.5 x 63.0 x 21.3 mm)
Weight 6.98 oz (198 g), (including battery & antenna)
