Model 5130
Party-Line Interface Module
Introduction
The Model 5130 Party-Line Interface Mod-
ule is a compact, self-contained unit for
use in custom broadcast, live-performance,
and general party-line intercom applica-
tions. The module provides a high-quality
2-channel party-line to analog line level
(“4-wire”) audio signal interface in an easy
to use yet technically sophisticated pack-
age. The module’s basic functions include
two channels of 2-wire-to-4-wire conver-
sion with auto-null capability, input and
output level metering, a +28 volt DC party-
line power source with two channels of 200
ohm intercom audio termination, and DC
output control and status monitoring. Party-
line beltpack user devices can be directly
connected. Two analog inputs and two
analog outputs interface the Model 5130
with a variety of external audio transport,
matrix intercom, and infrastructure equip-
ment. Module operation requires only an
externally-provided source of 12 volts DC.
Advanced features include remote control
and monitoring capability when installed
with remote access modules available from
Studio Technologies.
Applications for the Model 5130 include
sports broadcasting booth packages,
remote news gathering “fly packs,” stadium
audio/video interface (I/O) locations, and
government/corporate/performance space/
aerospace test infrastructure projects. The
number of Model 5130 modules used in a
project can vary widely—from one to
dozens. And in each case the performance
will be completely “pro” with audio quality,
reliability, and installation flexibility match-
ing that of larger-scale products. Typical
applications will find the Model 5130’s 4-
wire audio inputs and outputs being inter-
faced with fiber-optic transport modules,
matrix intercom systems, and audio/video
routers.
The Model 5130 provides a full-featured
2-channel interface which includes two
2-wire-to-4-wire hybrid circuits with auto-
matic nulling capability. The analog hybrid
circuitry provides excellent audio quality
and high return-loss. Audio level meters
provide confirmation of system perfor-
mance during setup and operation. The
Model 5130’s party-line interface is acces-
sible using a 3-pin male XLR connector.
This allows industry-standard party-line
intercom user beltpacks to be directly in-
terfaced. With a maximum output current of
180 milliamperes, up to three of the popu-
lar RTS® BP325 devices can be directly
connected. Devices from Clear-Com® are
also compatible.
