A large part of the Model 215’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 broad-
cast and production applications, a variety
of pushbutton operating modes are avail-
able. The main pushbutton can be selected
to operate from among four modes. In
the “push-to-mute” mode the pushbutton
performs a momentary mute of the audio
signal associated with the main output
channel. In this way a “cough” pushbut-
ton 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 ap-
propriate 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 two pushbutton switches associated
with the talkback functions can be config-
ured 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 operation
of which is discussed in the previous para-
graph. The hybrid mode is especially useful
when the Model 215 is used in a produc-
tion-support application.
Overall Model 215 operation can be con-
figured from among one on-air and two
production modes. The Model 215’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 215
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 occurring
between the speakers and the active
microphone.
Headphone Output
The Model 215 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
