MODEL 372A

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.
