Adjusting the Input Gain
The two bicolor Modulation LEDs on the control panel
provide a visual indication of the audio signal level enter-
ing the transmitter. The LEDs will glow either red or green
to indicate modulation levels as shown in the following
table.
Signal Level
Less than -20 dB
-20 dB to -10 dB
-10 dB to +0 dB
+0 dB to +10 dB
Greater than +10 dB
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
enter 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
Turning Power ON and OFF).
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 will
occur during use, or set the output level of the in-
strument 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

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 adjustment set according to these instruc-
tions, and do not change it to adjust the audio
output level of the receiver.
Selecting Frequency
The setup screen for frequency selection offers several
ways to browse the available frequencies.
