A large part of the Model 214’s unique
power is the ability to configure the opera-
tion of the main and talkback functions.
To meet the needs of the many specific
broadcast and production applications, a
variety of pushbutton operating modes are
available. The main pushbutton can be se-
lected to operate from among four modes.
In the “push-to-mute” mode the pushbut-
ton performs a momentary mute of the au-
dio signal associated with the main output
channel. In this way a “cough” pushbutton
function is created, something typically
required for television sports broadcasting.
In the “push-to-talk” mode the pushbutton
provides a momentary active function
for the main output. This mode would be
appropriate for an application such as sta-
dium announcement. An alternate action
“latching” configuration allows the push-
button to enable or disable the audio signal
associated with the main output channel as
desired. This is useful in radio broadcast-
ing, announce-booth, or voice-over appli-
cations. The fourth mode provides a hybrid
function, supporting both push-to-talk and
tap-to-enable/tap-to-disable operation. This
operation is similar to that found in many
broadcast intercom system user stations.
The pushbutton switch associated with
the talkback function can be configured
to operate from either of two modes. One
of the modes supports a “push-to-talk”
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, ra-
dio, and streaming broadcast applications.
When on-air is selected the audio signal
associated with the main output channel
will always mute when the talkback func-
tion is active. This prevents audio that’s in-
tended 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 produc-
tion modes also supports using the head-
phone 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 en-
hance intelligibility and help prevent acous-
tical feedback from occurring between the
speakers and the active microphone.
Headphone Output
The Model 214 provides a number of con-
figuration choices that relate to the head-
phone output. These choices include the
headphone output gain range, which audio
sources are utilized, how the rotary level
controls function, and what sidetone action
will take place. Four headphone control
source assignment modes are offered.
These modes impact how the three rotary
controls adjust the four Dante input chan-
nels and the sidetone audio signals.
