Introduction

The Model 373A Intercom Beltpack is a highly compact user-

worn device that combines a single channel of talk and two

channels of listen. The unit begins with the features offered by

traditional analog party-line (PL) intercom user devices and adds

a range of new capabilities, along with the advanced perfor

mance and flexibility that Dante® audio-over-Ethernet provides.

Over a standard IP network, multiple Model 373A and other

compatible Studio Technologies’ beltpack units can be used to

create party-line intercom applications with help from an external

Dante-enabled audio matrix such as the Studio Technologies’

Model 5422 Dante Intercom Audio Engine. Alternately, Model

373A units can be used “point-to-point” or interfaced with

Dante-compatible matrix intercom systems.

Having one talk and two listen channels may seem unconven

tional. But it can be ideal for many “real-world” applications.

Often an intercom user is primarily listening and non-verbally

responding to requests made by producers, directors, or stage

managers. Typically, the Model 373A will be configured to be

part of one talk-and-listen party-line intercom channel. During

the time that an event is taking place the listen function will

serve a much more important role; the talk function will rarely

be utilized. However, the second listen channel will often be

important. Typically, it will be designated as a program-listen or

“show audio” channel. The two listen channels, along with the

ability to receive and display call signals, allow the Model 373A

to very effectively support production personnel in a compact

and cost-effective manner.

Only a single Power-over-Ethernet (PoE) connection is required

for operation. Key user features can be easily configured using

the STcontroller software application. Configurable parameters

include electret microphone powering, microphone preamplifier

gain, talk button operation, and headphone channel assignment.

Features include integrated sidetone, call signal receive display,

and remote mic kill (“talk off”). The range of capabilities, along

with the excellent audio quality provided by the digital audio

signal path, offers a unique and powerful user experience.

Setting up and configuring a Model 373A is simple. An ether

CON® RJ45 receptacle is used to interconnect with a standard

twisted-pair Ethernet port associated with a local-area network

(LAN). This connection provides both power and bidirectional

digital audio. The Model 373A is compatible with both broadcast

and “gaming” headsets.

A broadcast or intercom-style monaural headset with a dynamic

or electret (DC-powered) microphone can be interfaced with

the Model 373A using a 4-pin XLR connector. The Model 373A

also directly supports connection of stereo earbuds or gaming

headsets that utilize a 3.5 mm 4-conductor TRRS plug. These

moderately priced devices, commonly associated with mobile

phones or personal computers, are often of high-quality and

may be preferred for some applications. With the Model 373A’s

moderate price and ability to support a broad range of headset

devices the overall cost of deploying an intercom system can

often meet budget goals.

The STcontroller software application is used to select the unit’s operating parameters. The talk pushbutton switch can be configured for optimal operation. Two “push-in/push-out” (“pop-out”) rotary controls make it easy to set and maintain the desired headphone output level. The Model 373A’s compact enclosure is made from an aluminum alloy which offers both light weight and ruggedness. A stainless steel belt clip, located on the back of the unit, allows direct attachment to a user’s clothing.

Ethernet Data and PoE The Model 373A connects to an Ethernet data network using a standard 100 Mb/s twisted-pair Ethernet interface. The physical interconnection is made by way of a Neutrik® etherCON RJ45 receptacle. While compatible with standard RJ45 plugs, etherCON allows a ruggedized and locking interconnection for harsh or high-reliability environments.
