MODEL 372A
INTERCOM BELTPACK
Introduction
The Model 372A 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 performance and flexibility that
Dante® audio-over-Ethernet provides. Over
a standard IP network, multiple Model 372A
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
372A units can be used “point-to-point” or
interfaced with Dante-compatible matrix
intercom systems.
Having one talk and two listen channels may
seem unconventional. 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 372A 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 372A to very effectively support pro-
duction 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. Con-
figurable parameters include electret micro-
phone 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 372A
is simple. An etherCON® 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 372A is compatible with
both broadcast and “gaming” headsets.
