talkback functions. To meet the needs
of the many specific broadcast and pro-
duction applications, a variety of button
operating modes is available. The main
output button can be selected to operate
from among four modes. In the “push-to-
mute” mode the button performs a mo-
mentary mute of the main output. In this
way a “cough” button function is created,
something typically required for television
sports broadcasting. In the “push-to-talk”
mode the button provides a momentary
active function for the main output. This
mode would be appropriate for applica-
tions such as stadium announcement. An
alternate action “latching” configuration
allows the button to enable or disable the
main output as desired. This is useful in
radio broadcasting, announce-booth, or
voice-over applications. 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 button 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 operation of which is
discussed in the previous paragraph. The
hybrid mode is especially useful when the
Model 210 is used in a production-support
application.
IFB Input
A broadcast-standard “wet” (DC with au-
dio) IFB circuit can be directly connected
to the Model 210’s IFB input. Originated
by sources such as the RTS™ 4000-series
IFB system or IFB interface devices from
Studio Technologies, the connected IFB
circuit can provide DC power to operate
the Model 210 as well as two channels of
cue audio.
Cue Sources
The Model 210 allows the two IFB audio
sources to be selected for routing to the
headphone output. Originating in produc-
tion trailers, control rooms, or remote loca-
tions, these unbalanced sources normally
provide DC power and program-with-
interrupt audio on one channel and pro-
gram-only audio on the other. Each source
can be individually assigned to the left
channel, right channel, or both left and
right. This allows a wide variety of stereo
and mono headphone mixes to be created.
Some applications may benefit by being
able to connect standard line-level audio
signals to the Model 210. To meet this need
one or two optional line input cards can
be installed in the Model 210’s back panel.
Each card provides a female XLR-type con-
nector and transformer-isolated +4 dBu
nominal input circuit. Each source can be
individually assigned to the left channel,
right channel, or both left and right.
Headphone Output
Two rotary controls are provided for user
adjustment of the headphone output levels.
For application flexibility the actual function
of the two “pots” is configurable. For tradi-
tional on-air sports applications they can be
selected to the dual-channel (“level/level”)
mode which provides independent con-
trol of the left- and right-channel volume.
For use with dual-channel cue signals,
or to support user preference, the stereo
(“level/balance”) mode can be selected. In
this mode one control adjusts the overall
level of both the left and right channels,
