INTERCOM BELTPACK
the four talk channels does not impact the
headphone output. However, one button
configuration setting (Talk Disabled/Phone
Tap to Latch) assigns the associated button
to function as a channel listen audio on/off
selector.
Button Operation
Four pushbutton switches are associated
with the Model 374A’s four channels. How
they function will depend on the configura-
tion of the unit. Each button can be config-
ured independently.
Push to Talk
When a button has been configured for the
Push to Talk
mode how it functions is pretty
self-explanatory. Press and hold the button
when headset microphone audio is to be
sent out the associated Dante audio output
(transmitter) channel. The button’s green
LED will light to indicate that the output is
active. The button will not be lit when the
function is not active.
Push to Talk/Tap to Latch
If a button has been configured for the
Push to Talk/Tap to Latch
mode operation
is a bit different and certainly more flex-
ible. Press and hold the button to activate
the talk function. When released the talk
function will turn off. Momentarily pressing
(“tapping”) the button will cause the func-
tion to change states; off-to-on or on-to-off.
Whenever the talk function is active the
green LED will light. The button will not be
lit when the function is not active.
Talk Disabled
A button that is configured to the Talk
Disabled mode will never allow talk audio
to be sent to the associated Dante audio
output channel. But to provide “feedback”
that the button has been pressed the
button’s green LED will flash rapidly three
times. This says, in effect, “Yes, I recog-
nize that you pressed the button but I’m
not going to do anything in response!”
Talk Disabled/Phones Tap to Latch
In the Talk Disabled/Phones Tap to Latch
mode the button will never allow talk
audio to be sent to the associated Dante
audio output channel. Instead the button
will operate in a tap to enable/tap to dis-
able (alternate action or “toggle”) manner
and provide an audio channel listen on/off
function. The button’s orange LED will
light whenever audio is being sent to the
headphone output. The headphone output
level will continue to follow the setting of
the associated rotary level control.
Call (Button 4 Only)
When button 4 is configured for the Call
mode it will allow call signals to be gener-
ated whenever talk channels 1, 2, and/or 3
are active. The button functions in a
push-to-call manner and will light orange
whenever it is pressed and held. No mi-
crophone audio will be routed to audio
output 4. Button 4 will never light in re-
sponse to a call signal being present on
audio input 4. The headphone output level
will continue to follow the setting of the
rotary level control associated with audio
input 4.
Sidetone Function
The Model 374A includes a sidetone func-
tion that sends microphone audio to both
the left and right headphone output chan-
nels whenever one or more of the talk
buttons are active. The quality of the side-
tone audio should be excellent and will
provide Model 374A users with a confi-
dence signal that they are actively talking
to other intercom users. Sidetone audio
