but rather allow the pushbutton’s labeling
and location to be visible in low-light condi-
tions.
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 214’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 214 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 214 is set to either of the production
modes, the red LED will never light; the
green LED will light whenever microphone
audio is connected 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 whenev-
er the pushbutton is pressed and held.
• Alternate Action: If this mode is selected
the audio signal associated with the
main output channel will alternate be-
tween its active and muted states when-
ever 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
similar to the way talk pushbuttons func-
tion on user stations associated with
broadcast or production intercom sys-
tems. 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 pushbutton is momentarily “tapped”
the audio signal will change state. Upon
Model 214 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 214’s system mode is
configured for on-air and the main push-
button mode is set to alternate action or
hybrid.
Talkback activity will always cause the
audio signal associated with the main
output channel to be placed in its mut-
ed 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 asso-
ciated with the main output channel will
again be in its on (“latched”) state.
