INTERCOM BELTPACK
Talk Button Operation
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.
Operation
At this point everything should be ready
and Model 372A operation can commence.
An Ethernet connection with Power-over-
Ethernet (PoE) capability should have been
made. A headset terminated with a cable-
mounted 5-pin male XLR connector may
be plugged into the Headset A connector.
Alternately, a gaming or computer-type
headset will be connected to Headset B
using a 3.5 mm 4-conductor TRRS plug.
Using the Studio Technologies’ STcontroller
software application, the unit’s configura-
tion should have been selected to meet
the needs of the specific application. The
Model 372A’s Dante configuration settings
should have been selected using the Dante
Controller software application. In this way,
the Model 372A’s audio output channel
(Dante transmitter channel) and two audio
input channels (Dante receiver channels)
should have been routed, by way of Dante
“subscriptions,” to the receiver and transmit-
ter channels on associated Dante-enabled
equipment.
Initial Operation
The Model 372A will start to function as
soon as a Power-over-Ethernet (PoE) power
source is connected. However, it may take
20 to 30 seconds for full operation to com-
mence. Upon initial power-up the three sta-
tus LEDs, located on the bottom panel below
the etherCON RJ45 receptacle, will begin
to light as network and Dante connections
are established. The compressor active LED
might somewhat randomly flash for a brief
period. The green and orange LEDs that illu-
minate the talk pushbutton switch will light as
part of a short test sequence to indicate that
the application firmware (embedded soft-
ware) has started. The mic power LED will
also light for a short interval to indicate that
it is functioning. Once the test sequence has
completed and the Dante connection has
been established full operation will begin.
