To insert batteries, close the eject lever
and insert the upper contacts rst (closest

Gain
Gain can be set, from -7 to +44, by using the and arrow buttons.
Adjusting the Input Gain
The two bicolor Modulation LEDs on the top panel provide a visual indi-
cation 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 O O
-20 dB to -10 dB Green O
-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 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 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 occur during use, or set the output level of
the instrument or audio device to the maximum level that will be
used.

4) Use the UP and DOWN arrow buttons to adjust the gain until the
–10 dB glows green and the –20 dB LED starts to icker red dur-
ing 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 adjustment set according to these
instructions, and do not change it to adjust the audio output level
of the receiver.
Rollo (Low Frequency Roll-o)
The low frequency audio roll-o is adjustable to optimize performance
for ambient noise conditions or personal preference.
Low frequency audio content may be desirable or distracting, so the
point at which the roll-o takes place can be set to 20, 35, 50, 70, 100,
120 or 150 Hz.

Use the MENU/SEL button to toggle between options and the UP and
DOWN arrow buttons to adjust.
RF On?
Turn Rf o to preserve battery power while setting other transmit-
ter functions. Turn it back on to begin transmitting.. Use the UP and
DOWN arrow buttons to toggle and MENU/SEL to save.
