function. This is typically used for on-air
broadcast applications. The other mode
provides a hybrid function, the opera-
tion of which is discussed in the previous
paragraph. The hybrid mode is especially
useful when the Model 214 is used in a
production-support application.
Overall Model 214 operation can be con-
figured from among one on-air and two
production modes. The Model 214’s on-air
mode is appropriate for on-air television,
radio, and streaming broadcast applica-
tions. When on-air is selected the audio
signal associated with the main output
channel will always mute when the talk-
back function is active. This prevents
audio that’s intended for production or
support personnel from being sent out
the on-air audio path.
For non-on-air applications, the Model
214 can be configured to operate in either
of two “production” modes. These allow
the main output to be used as a second
talkback output, rather than always mut-
ing when the talkback function is active.
Using 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 214 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
