intended for on-air, announcement, or other
primary uses. Two LEDs display the on/off
status of the main output. Three additional
pushbutton switches control the status of
the talkback output channels. These are
the audio signals used to communicate
with producers, directors, spotters, or other
behind-the-scenes production personnel.
A status LED is associated with each of
the talkback pushbuttons. The pushbut-
ton switches use gold-plated contacts for
reliable long-term operation and include
backlighting using white LEDs. Three rotary
controls allow the user to adjust the con-
tent and level of the headphone output.
Microphone Input
The Model 216 provides a high-perfor-
mance microphone preamplifier which
offers low-noise, low-distortion, and high
headroom amplification over a 19 to 64 dB
range. The gain is adjustable in 3-dB steps.
A 2-digit display indicates the amplification
in dB. The microphone input is compat-
ible with balanced dynamic or condenser
microphones. Phantom power is provided
and meets the worldwide P48 standard.
A dual-color LED indicator serves as an
aid for optimizing the setting of the pre-
amplifier’s gain. Microphone signals are
connected to the Model 216 by way of a
standard 3-pin female XLR connector.
Microphone operating parameters can
be set both locally and by way of the
STcontroller remote control software
application. Two pushbutton switches,
accessible on the bottom of the unit, allow
adjustment of the microphone preamplifi-
er’s gain and the on/off status of P48 phan-
tom power. The STcontroller application
allows personal computer users to both
view and change the preamp gain and
P48 on/off status.
Output Channels and their
Operation
By way of the Dante interface, the Model
216 provides a main output channel and
three talkback output channels. The main
output channel is designed to serve as the
on-air, stadium announcement, or other
primary audio feed. The talkback output
channels are intended to provide produc-
tion trucks, control rooms, or support per-
sonnel with talent-originated cue signals.
A large part of the Model 216’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 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” pushbutton function is created,
something typically required for television
sports broadcasting. In the “push-to-talk”
mode the pushbutton provides a momen-
tary active function for the main output.
This mode would be appropriate for an
application such as stadium announce-
ment. An alternate action “latching” con-
figuration allows the pushbutton to enable
or disable the audio signal associated with
the main output channel 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.
