MODEL 204
ANNOUNCER’S CONSOLE
COMP LED lights solid while a user is talk-
ing at a normal voice level this will typically
indicate that the microphone preamplifier
gain setting should be reduced. Conversely,
if the COMP LED almost never lights when
normal talking is taking place, it’s possible
that changing the gain to a higher value
would be beneficial. Note that due to the
design of the circuitry the compressor ac-
tive LED will function whether or not the
main or talkback functions are active. Also,
the compressor function does not impact
the microphone output connector.
Main and Talkback Buttons
Two pushbutton switches are used to select
how the microphone signal is routed to the
two Dante output channels and the micro-
phone output connector. The button labeled
MAIN controls if the audio signal associated
with the microphone input will be present
on the Dante main output channel and the
microphone output connector that’s located
on the back panel of the Model 204. How
the button functions will depend on the
configuration choice that has been made
using STcontroller. When the main button’s
green LED is lit audio will be present on
both the Dante main output channel and
the microphone output connector. When the
main button’s red LED is lit audio will not be
present on the Dante main output channel
and the audio signal associated with the
microphone output connector will be muted.
The talkback functions allow the audio
associated with the microphone input to
be routed to the Dante talkback output
channel. When the talkback function is
active its green LED will be lit. How the
talkback button specifically functions and
whether it impacts the main button’s func-
tioning depends on the Model 204’s system
configuration.
Main Button Modes
There are five ways that the main push-
button switch can function. The way in
which it specifically operates depends on
its selected configuration.
• Push to Mute: If this mode is selected the
audio signal associated with the micro-
phone input will normally be active on
the Dante main output channel and the
microphone output connector. The audio
signal will mute whenever the main push-
button is pressed and held.
• Push to Talk: If this mode is selected the
audio signal associated with the Dante
main output channel and the microphone
output connector will be normally muted.
The audio signal will become active
whenever the main pushbutton is pressed
and held.
• Latching: If this mode is selected the
audio signal associated with the Dante
main output channel and the microphone
output connector will alternate between
the active and muted states whenever
the main pushbutton is pressed. Upon
Model 204 power up the audio signal will
be in its muted state.
• Push to Talk/Tap to Latch: This mode is
a combination of the Push to Talk and
Latching actions. It’s similar to the way
in which talk pushbuttons function on
user stations associated with broadcast
or production intercom systems. If the
main pushbutton is pressed and held the
audio signal associated with the Dante
main output channel and the microphone
output connector will become active and
remain active until the pushbutton is
released. If the main pushbutton is mo-
mentarily “tapped” the audio signal will
change state. Upon Model 204 power up
the audio signal will be in its muted state.
