Connecting the Signal Source
Microphones, line level audio sources and instruments 
can be used with the transmitter. Refer to the section 
entitled Wiring Hookups for Different Sources for 
details on the correct wiring for microphones to take full 
advantage of the Servo Bias circuitry.
Adjusting the Input Gain
The two bicolor Modulation LEDs on the control panel 
and keypad provide a visual indication of the audio 
signal level entering the transmitter. The LEDs will glow 
either red or green to indicate modulation levels as 
shown in the following table.
Signal Level  -20 LED  -10 LED
Less than -20 dB   Off   Off
-20 dB to -10 dB   Green   Off
-10 dB to +0 dB   Green   Green
+0 dB to +10 dB   Red   Green
Greater than +10 dB   Red   Red
NOTE: Full modulation is achieved at 0 dB, when 
the “-20” LED first turns red. The limiter can cleanly 
handle peaks up to 30 dB above this point.
It is best to go through the following procedure with the 
transmitter in the standby mode so that no audio will en-
ter the sound system or recorder during adjustment.
1) With fresh batteries in the transmitter, power the 
unit on in the standby mode (see previous section 
Powering On in Standby Mode).
2) Navigate to the Gain setup screen.

3) Prepare the signal source. Position a microphone 
the way it will be used in actual operation and have 
the user speak or sing at the loudest level that oc-
cur during use, or set the output level of the instru-
ment or audio device to the maximum level that will 
be used.
4) Use the   and   arrow buttons to adjust the gain 
until the –10 dB glows green and the –20 dB LED 
starts to flicker red during the loudest peaks in the 
audio.
5) Once the audio gain has been set, the signal can 
be sent through the sound system for overall level 
adjustments, monitor settings, etc. 
6) If the audio output level of the receiver is too high or 
low, use only the controls on the receiver to make 
adjustments. Always leave the transmitter gain ad-
justment set according to these instructions, and do 
not change it to adjust the audio output level of the 
receiver.
