MODEL 209
TALENT CONSOLE
Dante talkback transmitter (output) channel is active.
Upon power being initially applied to the Model 209
the talkback function will be inactive, the button will
light green, and audio will be present on the Dante
main transmitter (output) channel.
Momentary – Doesn’t Mute Main Out: If this mode
is selected when the talkback button is not pressed
the button will be lit green, the microphone signal
will be sent to the Dante main transmitter (output)
channel, and the Dante talkback transmitter (output)
channel will be muted. Whenever the talkback button
is pressed and held the button will light alternating
between green and orange, audio signal will continue
to be present on the Dante main transmitter (output)
channel, and the audio signal will also become active
on the Dante talkback transmitter (output) channel.
The button lighting both green and orange is intended
to indicate that both Dante transmitter (output) chan
-
nels are active.
Latching – Doesn’t Mute Main Out: If this mode is
selected the talkback function will alternate between
its off (inactive) and on (active) states whenever the
pushbutton is momentarily pressed. In either state
audio will be sent out the Dante main transmitter
(output) channel; it will never mute. The talkback
button will light green whenever the Dante main
transmitter (output) channel is active and the Dante
talkback transmitter (output) channel is not active.
It will alternate between green and orange when
-
ever the talkback function is active. This indicates
that audio is being sent to both the Dante main and
talkback transmitter (output) channels. Upon power
being initially applied to the Model 209 the talkback
function will not be active and no audio will be sent
to the Dante talkback transmitter (output) channel.
Audio will be sent only to the Dante main transmitter
(output) channel and the button will be lit green.
Disabled: If this mode is selected the talkback func-
tion is prevented from becoming active. Microphone
audio will always be sent to the Dante main transmit-
ter (output) channel and the talkback pushbutton will
be lit green. The Dante talkback transmitter (output)
channel will always be muted. Whenever the talk-
back button is pressed the button will flash green to
indicate to users that the talkback function has been
disabled. Whether or not the button is pressed no
change to the audio routing will ever take place; audio
will always be present on the Dante main transmitter
(output) channel.
Talkback Button – Remote Control
Choices are None, GPI 1, and GPI 2.
The Model 209 provides two remote control inputs
which are labeled GPI 1 and GPI 2. (GPI is an acro
-
nym for general-purpose input.) They can be used to
control the talkback function, serving as an external
version of the talkback pushbutton switch.
None: When selected for None, the two remote
control inputs, GPI 1 and GPI 2, will not impact the
operation of the Model 209.
GPI 1: When selected for GPI 1, its operation will im
-
pact the status of the talkback function. It will perform
the same function as the talkback pushbutton. When
GPI 1 is in it’s low (shorted) state it will perform the
same function as if the pushbutton switch is being
pressed.
GPI 2: When selected for GPI 2, its operation will im
-
pact the status of the talkback function. It will perform
the same function as the talkback pushbutton. When
GPI 2 is in it’s low (shorted) state it will perform the
same function as if the pushbutton switch is being
pressed.
System – Signal Present Display
Choices are Off and On.
The top surface of the knob associated with the
headphone level control can light as an indication of
the level of the audio associated with the two Dante
receiver (input) channels. This is accomplished by
lighting an RGB (red-green-blue) LED that is located
within the headphone level control. The top of the
knob surface will light green when signal levels are
in their normal range, yellow when the signal levels
are greater than normal, and red when the signal
levels are at risk of degrading audio performance.
Whether Off or On is selected will depend on user
preference.
System – Mic Level Display
Choices are Off, Always On, and On When Main
Active.
The Model 209’s multi-purpose display is located on
the front panel, directly below the headphone level
