applications. When on-air is selected the
audio signal associated with the main
output channel will always mute when one
or more of the talkback functions is active.
This prevents audio that’s intended for
production or support personnel from be-
ing sent out the on-air audio path.
For non-on-air applications, the Model 216
can be configured to operate in either of
two “production” modes. These allow the
main output to be used as a third talkback
output channel, rather than always muting
when a talkback function is active. Us-
ing these production modes the unit can
be even more powerful when used in a
live event application, such as serving as
a small “IFB” console for a sports-event
spotter, musical director, or production
assistant. In addition to changing how
the main output functions, one of the
production modes also supports using
the headphone output for connection
with amplified speakers. The headphone
output level will automatically be reduced
(attenuate or “dim”) whenever the main
or talkback output channels are active.
This can enhance intelligibility and help
prevent acoustical feedback from occur-
ring between the speakers and the active
microphone.
Headphone Output
The Model 216 provides a number of
configuration choices that relate to the
headphone output. These choices impact
which audio sources are utilized, how the
rotary level controls function, and what
sidetone action will take place. Four head-
phone control configuration modes are of-
fered. These modes impact how the three
rotary controls adjust the four Dante input
channels and the sidetone audio signals.
The first two modes support standard on-
air applications and use only Dante input
channels 1 and 2. In the broadcast world
these two signals are often referred to
as talent cue or IFB audio. They typically
originate in production trailers or control
rooms and provide one channel of pro-
gram-with-interrupt audio and a second
channel with program-only audio. The
third and fourth configuration modes allow
all four of the Dante-provided audio sourc-
es to be utilized. These can be useful for
more complex or specialized situations.
The three headphone level controls (“rota-
ry pots”) are provided for setting the “mix”
of the selected sources as well as adjust-
ing the overall headphone output level.
How these controls function depends on
the selected headphone control mode.
As previously mentioned, the first mode
is intended to support traditional on-air
sports applications. In this mode the left
and center controls act in a dual-channel
(“level/level”) fashion, allowing indepen-
dent control of the left- and right-channel
volume.
For use with dual-channel or stereo cue
signals, the second mode provides a ste-
reo (“level/balance”) mode. In this mode
the left control adjusts the level of both
input channels 1 and 2, while the center
control allows adjustment of the left/right
level balance. In both modes the right
control is used to adjust the level of the
sidetone signal.
In the third headphone control mode the
left control adjusts the level of both in-
put channels 1 and 2, the center control
adjusts the level of both input channels 3
and 4, while the right control adjusts the
sidetone level.
