operates depends on the selected con-
figuration. Five LED indicators are located
adjacent to the pushbuttons and reflect
the status of the audio signals associated
with the main and talkback output chan-
nels. The pushbuttons’ clear lenses are
backlit using white LEDs. The intensity
(brightness) of the LEDs is configured from
a choice of two values, low or high. The
backlighting does not provide an indication
of the associated pushbutton’s status nor
do they serve as a tally function, but rather
allow the pushbutton’s labeling and loca-
tion to be visible in low-light conditions.
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
any 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 any 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 when-
ever 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 sim-
ilar 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 pushbutton is released. If the push-
button 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
configured for on-air and the main push-
button mode is set to alternate action or
hybrid.
