Main Button Modes
Depending on the selected configuration, there are five
ways the main pushbutton switch can function:
Push to Mute:
If this mode is selected, the audio signal
associated with the Dante main transmitter (output) channel
is normally active. The audio signal will mute whenever the
pushbutton switch is pressed and held.
Push to Talk: If this mode is selected, the audio signal
associated with the Dante main transmitter (output) channel
is normally muted. The audio signal will become active
whenever the pushbutton switch is pressed and held.
Latching: If this mode is selected, the audio signal associ-
ated with the Dante main transmitter (output) channel will
alternate between its active and muted states whenever
the pushbutton switch is pressed. Upon 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 modes. It’s similar to the way
talk pushbuttons function on user stations associated with
broadcast or production intercom systems. If the push-
button is pressed and held the audio signal associated with
the Dante main transmitter (output) channel will become
active until the pushbutton switch is released. If the push-
button switch is momentarily “tapped” the audio signal will
change state. Upon Model 214A power up the audio signal
will be in its muted state.
Push to Mute/Tap to Latch:
This mode is a combination
of the Push to Mute and Latching modes. Whenever the
main button is momentarily “tapped” its status will alter-
nate between active and muted. When the main button’s
function is active and the main button is pressed and held
the audio signal will mute on the Dante main transmitter
(output) channel. It will stay in this condition until the main
button is released. Upon Model 214A power up the audio
signal will be in its muted state.
Main Output vis-à-vis Talkback Activity
This short section applies only in the case where the Model
214A’s system mode is configured for on-air and the main
pushbutton mode is set to Latching, Push to Talk/Tap to
Latch, or Push to Mute/Tap to Latch.
Talkback activity will always cause the audio signal asso-
ciated with the Dante main transmitter (output) channel
to be placed in its muted state. If the audio signal was in
the “latched-on” state when talkback activity began, once
talkback activity ends that state will resume; the audio
signal associated with the Dante main transmitter (output)
channel will again be in its on (“latched”) state.
Talkback Button and LED Indicator
The second pushbutton switch from the left, factory labeled
TALKBACK, controls the audio signal associated with the
Dante talkback transmitter (output) channel. The manner in
which the talkback pushbutton switch functions depends on
the way it has been configured. One LED indicator, green
in color, is located directly above the talkback pushbutton
switch. It will light whenever the microphone audio signal
is connected to its associated Dante talkback transmitter
(output) channel. If the Model 214A’s system mode is
selected for on-air, whenever the talkback function is active
the audio signal associated with the Dante main transmitter
(output) channel will be placed in its muted state. If the
Model 214A is selected for either of the production modes,
the status of the talkback pushbutton switch will not impact
the status of the audio signal associated with the Dante
main transmitter (output) channel.
Talkback Button Modes
The operation of the talkback pushbutton switch can be
independently configured using the STcontroller software
application. Depending on the selected configuration, there
are three ways the talkback pushbutton switch can function:
Push to Talk: If this mode is selected, the audio signal asso-
ciated with a Dante talkback transmitter (output) channel is
normally muted. The audio signal will become active when-
ever the talkback pushbutton switch is pressed and held.
Latching: If this mode is selected, the audio signal asso-
ciated with a Dante talkback transmitter (output) channel
will alternate between its active and muted state whenever
its pushbutton is pressed. Upon Model 214A power up the
Dante talkback transmitter (output) channels will be in their
muted state.
Push to Talk/Tap to Latch:
This mode is a combination
of push to talk and latching. If the pushbutton switch is
pressed and held, the audio signal associated with the
Dante talkback transmitter (output) channel will become
active until the talkback pushbutton switch is released. If
the talkback pushbutton switch is momentarily “tapped” the
audio signal will change state. Upon Model 214A power up
the talkback audio signal will always be in its muted state.
Headphone Output
Three rotary controls (“pots”) are located on the Model
214A’s front panel and are associated with the headphone
output. The way these controls function will depend on
configuration within the STcontroller software application
of the Audio Sources and Routing configuration. There
are five modes available and each is unique. The overall
level of the headphone output is established using the gain
range configuration. Another configuration setting selects
whether the headphone output channels will maintain a
