MODEL 373A
INTERCOM BELTPACK
Headphone Output Channel Routing
Choices are Left, Right, and Left and Right.
Two Dante transmitter (output) channels can
be assigned to the Model 373As two Dante
receiver (input) channels using the Dante
Controller application. How these two au-
dio signals are routed to the Model 373As
headphone output channels can be inde-
pendently configured. For flexibility, each
input source has three routing options. They
can be independently configured for send-
ing only to the left channel, only to the right
channel, or sending to both the left and right
headphone output channels.
If a headset is to be connected to Headset
A then both input channels should be routed
to the left channel of the headphone output.
(Remember that Headset A only provides a
connection to the headphone output’s left
channel.) If a headset is to be connected
to Headset B then the input channels can
be assigned to the two headphone output
channels as desired. A stereo, dual-channel
monaural, or single-channel monaural con-
figuration can be created as necessary to
best support an application.
Sidetone – Level
Choices are Off, Low, Medium Low,
Medium, Medium High, and High.
The Model 373A includes a sidetone function
that allows microphone audio coming from
the microphone input section to be sent to
the headphone output. This serves as a user
confirmation that they are actively sending
audio to the talk output channel. Sidetone
audio will only be routed to the headphone
output when the talk channel is active. The
level of the sidetone audio can be selected
from among five values. The correct value
is simply the one that makes the user most
comfortable. Sidetone audio can also be dis-
abled by selecting Off. Selecting Off would
be useful only in special applications such
as during troubleshooting or where user talk
audio is being returned as part of their listen
audio signals. The two rotary level controls
will not impact the sidetone level.
Button Operation – Talk
Choices are Push to Talk, Latching, and
Push to Talk/Tap to Latch.
This configuration section allows selection
of how the talk button will function. When the
Push to Talk mode is selected the operation
is self-explanatory. Only when the talk button
is pressed and held will talk audio be sent
out the Dante transmitter channel.
When the Latching mode is selected tapping
(momentarily pressing) the button will cause
the function to “latch” into the talk active
mode. Tapping the button again will cause
the function to “unlatch” and talk will no
longer be active.
When the Push to Talk/Tap to Latch mode
is selected a “hybrid” function of sorts is en-
abled. Pressing and holding the talk button
will enable audio to be sent out the Dante
transmitter channel. When the button is
released audio will stop being sent out the
transmitter channel. Tapping (momentarily
pressing) the button will cause the function
to “latch” into the talk active mode. Tapping
the button again will cause the function to
“unlatch” and talk will no longer be active.
Many applications are best served when the
buttons are configured in the Push to Talk
mode. This ensures that a channel can’t ac-
cidentally be left in its talk active mode. But
there are certainly valid situations when the
Latching mode or Push to Talk/Tap to Latch
mode settings will prove to be very useful.
