About Setting Audio Gain
The two bicolor Modulation LEDs (located at the bot-
tom of the control panel) provide a visual indication
of the audio signal level entering the transmitter.
The modulation
LEDs are oriented
and labeled to be
read when holding
the mic capsule in
front of your mouth.
The gain should be
set so that the -20
LED just turns red
on the loudest peak.
The LEDs will glow either red or green to indicate
modulation levels as shown in the following table.
Signal Level

-10 LED

It is best to go through the following procedure with
the transmitter in the “standby” mode so that no au-
dio will enter the sound system, which could cause
feedback.
1)
With fresh batteries in the transmitter, power the
unit on into “standby” (no transmission) mode.
2)
Press the
MENU/SEL
button once to enter the
setup menu. Use the UP/DOWN buttons to
select
Gain
. Press the
MENU/SEL
button again
to enter the setup screen.
3)
Hold the microphone the way it will be used in
actual operation.
4)
Speak or sing at the same voice level that will
actually be used during the program, while
observing the modulation LEDs. Use the UP/
DOWN buttons to adjust the gain until the
–20
dB
LED starts to flicker red and the
–10 dB
glows green.
5)
Once the audio gain has been set, the signal
can be sent through the sound system for
overall level adjustments, monitor settings, etc.
To do this, the unit must be set to transmit (see
Powering On and Off
, and the
Standby Mode
on page 7).
NOTE: Full modulation is achieved when the
-20 LED first turns red. 30 dB of clean limiting
is available above this point.
Mute and Talkback
Functions
A special button (the
Side Button
) on the outside of
the housing can be configured to provide a mute or
talkback function, or to be inoperative.
Side Button
The
Side Button Setup Switch
on the control panel
opens a setup screen to select the function of the
Side Button
.

TalkBk
Mute
is a “push on/push” off function that toggles on
and off each time the Side Button is pressed. The
mute function defeats the audio in the transmitter, so
it works in all compatibility modes and will all receiv-
ers.
Talkback
is a “push to talk” function that is active
only while the button is pressed. The talkback func-
tion provides a communication channel when used
with a receiver equipped with this function, such as a
Venue Wideband receiver with firmware that enables
this function. When pressed and held in, the side
switch re-directs the audio output to a different audio
channel on the receiver. As soon as the switch is
released, audio is returned to the program channel.
NOTE: The Talkback function is only available
in the 400/Hybrid compatibility mode. It will
not allow you to enable Talkback in any other
mode..
