Adjusting the Input Gain

The two bicolor Modulation LEDs on the control panel
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
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 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 Turn-
ing 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 ad-
justment set according to these instructions, 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.
