is always used by the talkback outputs.
In addition, the audio source for the main
output can be selected to be either the
output of the microphone preamplifier or
the output of the compressor. While possi-
bly not appropriate for major on-air situa-
tions, having dynamic range control of the
main output can offer increased perfor-
mance for many applications. These could
include stadium announcement positions,
sports events using nonprofessional on-air
talent, and situations where cable cross-
talk is of concern.
User Controls and Status
Indicators
Three pushbutton switches, four LED
indicators, and two rotary controls provide
the user with a clear, easy-to-use inter-
face. One pushbutton switch controls the
status of the main output. This is the audio
output intended for on-air, announcement,
or other primary uses. Two LEDs display
the on/off status of the main output. Two
additional pushbutton switches control the
status of the two talkback outputs. These
are the audio outputs used to communi-
cate with producers, directors, “spotters,”
or other behind-the-scenes production
personnel. A status LED is associated with
each talkback button. Two rotary controls
allow the user to adjust the level of the
headphone output.
Flexibility
A large part of the Model 220’s unique
power is the ability to configure the op-
eration of the main output and talkback
functions. To meet the needs of the many
specific broadcast and production ap-
plications, 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 momen-
tary 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 two buttons associated with the talk-
back functions can be configured to oper-
ate 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 220 is used in a production-support
application.
In addition to the two modes provided for
talkback 1, the button associated with talk-
back 2 supports three additional operating
modes. One mode allows talkback 2 to be
disabled. This is useful when only talkback
1 is to be utilized. The other two modes
provide special momentary and hybrid
functions. With these modes the operation
of the main and talkback outputs are not
impacted. This allows the talkback 2 but-
ton to control the state of the Model 220’s
auxiliary relay, making specialized imple-
mentations possible.
