The three pushbutton switches associ-
ated with the talkback functions 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 func-
tion, the operation of which is discussed in
the previous paragraph. The hybrid mode
is especially useful when the Model 216 is
used in a production-support application.
Overall Model 216 operation can be con-
figured from among one on-air and four
production modes. The Model 216’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 either or
both talkback functions are active. This
prevents audio that’s intended for produc-
tion or support personnel from being sent
out the on-air audio path.
For non-on-air applications, the Model 216
can be configured to operate in one of
four production modes. These allow the
main output to be used as a fourth talk-
back output channel, rather than always
muting when a 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 (talent cueing) console for
a sports-event spotter, musical director, or
production assistant. In addition to chang-
ing how the main output functions, two of
the production modes also support using
the headphone output for connection with
amplified speakers. In these modes 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
occurring between the speakers and the
active microphone.
REMI IFB Creation
Two production modes, production with
tone and production with dim and tone,
are specifically included to support the
tone operated IFB function that’s part
of the Studio Technologies’ Model 5422
Dante Intercom Audio Engine. These
modes add an 18 kHz sine-wave signal
to the talk audio so that activation of the
Model 5422’s TOX (tone operated inter-
rupt) IFB function will occur. The TOX func-
tion supports the REMI production model
where production personnel are present
at one physical location while a broadcast
event takes place at another. Only audio
paths linking the sites are required for pro-
fessional-quality IFB signals to be created.
The Model 216 can serve as a 4-channel
IFB master station while the Model 5422,
located at the event site, will perform the
switching between interrupt audio (coming
from the Model 216) and program audio
(originating at the event site).
Headphone Output
The Model 216 provides a number of
configuration choices that relate to the
headphone 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 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 Dante audio input
channels 1 and 2. In the broadcast world
