• Hybrid: This mode is a combination of
push to talk and alternate action. It’s
similar to the way talk buttons function
on user stations associated with broad-
cast or production intercom systems. If
the button is pressed and held, the main
output channel will become active until
the button is released. If the button is
momentarily “tapped” the main output
channel will change state. Upon Model
212 power up the main output channel
will be in its muted state.
Main Output vis-à-vis Talkback Activity
This short section applies only to the case
where the Model 212’s system mode is
configured for on-air and the main output
button mode is set to alternate action or
hybrid.
Talkback activity will always cause the
main output channel to be placed in its
off state. If the main output channel was
in the “latched” on state when talkback
began, once talkback activity ends that
state will resume; the main output channel
will again be in its on (“latched”) state.
Talkback Output Button and LED
Indicator
The button on the right, factory labeled
TALKBACK, controls the talkback output
channel. The manner in which the talk-
back button functions depends on the
way it was configured. One LED indicator,
green in color, is located directly above
the talkback button. It lights whenever
the talkback output channel is active. If
the Model 212’s system mode is selected
to on-air, whenever the talkback function
is active the main output channel will be
placed in its muted state. If the Model 212
is selected to the production mode, the
status of the talkback output channel will
not impact the main output channel.
Talkback Output Button Modes
• Push to talk: If this mode is selected
the talkback output channel is normally
muted. The talkback output channel will
become active whenever the button is
pressed and held.
• Hybrid: This mode is a combination of
push to talk and alternate action. If the
button is pressed and held, the talk-
back output channel will become active
until the button is released. If the button
is momentarily “tapped” the talkback
output channel will change state. Upon
Model 212 power up the talkback output
channel will be in its muted state.
Headphone Output Level Controls
Two rotary controls (“pots”) are located
on the Model 212’s front panel and are
associated with the headphone output.
The way the controls function depends
on the selected configuration. One
configuration parameter sets the controls
to operate in a level/level or a level/
balance mode. Another parameter allows
the left/right assignment of the controls
to be reversed. A third parameter selects
whether the headphone output channels
will maintain a minimum output level or
can be fully muted.
Level/Level Mode
When set to the level/level mode, the two
controls operate independently. Each
control sets the output level of one chan-
nel of the stereo headphone output. If con-
figured to the normal mode, the control
on the left side is used to adjust the level
of the headphone output’s left channel.
The control on the right is used to adjust
the level of the right channel. If configured
to the reverse left/right mode, the control
on the left side adjusts the headphone
