MODEL 205
ANNOUNCER’S CONSOLE
COMP and displays the status of the mi-
crophone audio compressor function. This
function controls the dynamic range of the
audio signal that can be present on the
Dante audio output (transmitter) channels
and sidetone audio sent to the headphone
output versus the signal present on the
microphone input. The compressor LED
will light whenever the input level from the
microphone, along with the configured
microphone preamplifier gain, is such that
the dynamic range of the signal is being
actively controlled. It’s perfectly acceptable
for this LED to light intermittently whenever
a user is talking at a normal voice level
into an associated microphone. But if the
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. Converse-
ly, 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
active 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
Three pushbutton switches are used to
select how the microphone signal is routed
to the three Dante output channels and the
microphone output connector. The button
labeled MAIN controls if the audio signal
associated with the microphone input will
be present on the Dante main output chan-
nel and the microphone output connector
that’s located on the back panel of the
Model 205. 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 con-
nector. 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 con-
nector will be muted.
The talkback functions allow the audio
associated with the microphone input to
be routed to either or both of the Dante
talkback output channels. When a talkback
function is active its green LED will be
lit. How a talkback button will specifically
function and whether it impacts the main
button’s functioning depends on the Model
205’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
