Talkback activity will always cause the
audio signal associated with the main out-
put channel 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 re-
sume; the audio signal associated with the
main output channel will again be in its on
(“latched”) state.
Talkback Buttons and LED
Indicators
The second pushbutton from the left, facto-
ry labeled TALKBACK 1, controls the audio
signal associated with the talkback output
channel 1. The third pushbutton from the
left, factory labeled TALKBACK 2, controls
the audio signal associated with the talk-
back output channel 2. The pushbutton
on the right, factory labeled TALKBACK 3,
controls the audio signal associated with
the talkback output channel 3. The manner
in which the talkback pushbuttons function
depends on the way they were configured.
One LED indicator, green in color, is lo-
cated directly above each talkback push-
button. It lights whenever the microphone
audio signal is connected to its associ-
ated talkback output channel. If the Model
216’s system mode is selected for on-air,
whenever any of the talkback functions are
active the audio signal associated with the
main output channel will be placed in its
muted state. If the Model 216 is selected
for any of the production modes, the status
of the talkback pushbuttons will not impact
the status of the audio signal associated
with the main output channel.
Talkback Button Modes
Depending on the selected configuration,
there are two ways the talkback pushbut-
ton can function:
• Push to Talk: If this mode is selected
the audio signal associated with the
talkback output channels is normally
muted. The audio signal will become
active whenever its associated talkback
pushbutton is pressed and held.
• Hybrid: This mode is a combination of
push to talk and alternate action. If the
pushbutton is pressed and held, the
audio signal associated with that talk-
back output channel will become ac-
tive until the talkback pushbutton is
released. If the talkback pushbutton is
momentarily “tapped” the audio sig-
nal will change state. Upon Model 216
power up the audio signal will always be
in its muted state.
Headphone Output
Three rotary controls (“pots”) are located
on the Model 216’s front panel and are as-
sociated with the headphone output. The
way the controls function depends on the
selected headphone output configuration.
One configuration parameter sets what
audio input signals are assigned to the
controls. There are four modes available.
Another parameter selects whether the
headphone output channels will maintain
a minimum output level or can be fully
muted.
To understand exactly how the level con-
trols on a specific Model 216 will function
requires knowledge of how that unit has
been configured. Please refer to the Con-
figuration section of this guide for details.
It may require a bit of study to fully under-
stand how the controls will function. The
author would like to be able to provide a
simple explanation. But there are really
four simple explanations, one for each
configuration choice!
