Main Button and LED
Indicators
The pushbutton on the left, factory labeled
as COUGH, functions according to the
selected configuration. Two LED indicators,
located directly above the pushbutton, are
associated with the status of the audio sig-
nal on the main output channel. The green
LED, located on the right, is lit whenever
the microphone audio signal is connected
to the main output channel. This could be
considered as an “on-air” or “mic-active”
indicator. If the Model 216’s system mode
is configured to on-air, the red LED, located
on the left, will be lit when the audio signal
associated with main output channel is
muted.
If the Model 216 is configured to operate
in either of the production modes, the red
LED will never light. This is to reflect the fact
that the main pushbutton has now taken
on a function similar to that of the talkback
pushbutton. To clarify, when the Model 216
is set to either of the production modes, the
red LED will never light; the green LED will
light whenever microphone audio is con-
nected to the main output channel.
Main Button Modes
Depending on the selected configuration,
there are four ways the main pushbutton
can function:
• Push to Mute: If this mode is selected
the audio signal associated with the
main output channel is normally active.
The audio signal will mute whenever the
pushbutton is pressed and held.
• Push to Talk: If this mode is selected the
audio signal associated with the main
output channel is normally muted. The
audio signal will become active whenever
the pushbutton is pressed and held.
• Alternate Action: If this mode is selected
the audio signal associated with the main
output channel will alternate between its
active and muted states whenever the
pushbutton is pressed. Upon power up
the audio signal will be in its muted state.
• Hybrid: This mode is a combination of
push to talk and alternate action. It’s simi-
lar to the way talk pushbuttons function
on user stations associated with broad-
cast or production intercom systems. If the
pushbutton is pressed and held the audio
signal associated with the main output
channel will become active until the push-
button is released. If the pushbutton is
momentarily “tapped” the audio signal will
change state. Upon Model 216 power up
the audio signal will be in its muted state.
Main Output vis-à-vis Talkback
Activity
This short section applies only in the case
where the Model 216’s system mode is con-
figured for on-air and the main pushbutton
mode is set to alternate action or hybrid.
Talkback activity will always cause the audio
signal associated with the main output chan-
nel to be placed in its muted state. If the
audio signal was in the “latched-on” state
when talkback activity began, once talkback
activity ends that state will resume; the audio
signal associated with the main output chan-
nel will again be in its on (“latched”) state.
Talkback Buttons and LED
Indicators
The pushbutton in the middle, factory la-
beled TALKBACK 1, controls the audio
signal associated with the talkback output
channel 1. The pushbutton on the right, fac-
tory labeled TALKBACK 2, controls the audio
signal associated with the talkback output
