Introduction
The Model 371A Intercom Beltpack begins with the
features offered by 2-channel broadcast-style party-line
intercom user devices then adds support for traditional
single-channel headsets. Applications that have tradition
-
ally deployed single-channel analog party-line intercom
systems from firms such as Clear-Com® can now easily
upgrade to a high-performance dual-channel system. To
maintain compatibility and user familiarity, legacy head
-
sets that use a 4-pin female XLR connector are directly
compatible.
The Model 371A includes 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 371A units can be used in party-line (PL)
intercom applications with help from an external Dante-
enabled audio matrix such as the Studio Technologies
Model 5422 Dante Intercom Audio Engine. Alternately,
units can be used “point-to-point” or interfaced with Dante-
compatible matrix intercom systems.
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, sidetone level, and
talk button operation. User features include microphone
dynamic range control, call function, and remote mic kill
(“talk off”). The wide range of capabilities, along with the
excellent audio quality provided by the digital audio signal
path, offers a unique and powerful user experience.
Set up and configuration of the Model 371A 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. A broadcast or inter
-
com-style headset with a dynamic or electret (low-voltage
DC-powered) microphone interfaces with unit using a 4-pin
XLR connector. The Model 371A’s enclosure is made from
an aluminum alloy which offers both light weight and rug
-
gedness. A stainless steel “belt clip,” located on the back
of the unit, allows direct attachment to a user’s clothing.
The audio quality of the Model 371A’s audio channels is ex
-
cellent, with low distortion, low noise, and high headroom.
Careful circuit design and rugged components ensure
long, reliable operation. A wide range of applications can
be supported, including theater facilities, over-the-air and
streaming broadcasting, corporate and government AV
installations, aerospace command and control, and post-
production facilities.
