Studio Technologies M5132S Partyline Interface Module, 4-Wire

The Studio Technologies 5132S Party-Line Interface Module is a compact, self-contained unit for use in custom broadcast, live performance, and general party-line intercom applications. 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 package. The module’s basic functions include two channels of 2-wire-to-4-wire conversion 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. With the internal party-line power source enabled, beltpack user devices can be directly connected. Alternatively, the 5132S can be connected into an existing party-line circuit that includes a power source and intercom audio terminations. Two analog inputs and two analog outputs interface the 5132S with a variety of external audio transport, matrix intercom, and infrastructure equipment. Module operation requires only an externally-provided source of 12 volts DC. Advanced features include remote control and monitoring capability when installed with a Studio Technologies’ Model 5190 Remote Access Module.

Applications for the Model 5132 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 5132S 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 matching that of larger-scale products. Typical applications will find the 5132S' line-level audio inputs and outputs being interfaced with fiber optical transport modules, matrix intercom systems, and audio/video routers. The flexibility of the 5132S Party-Line Interface Module allows direct connection to either intercom beltpack devices or an existing party-line intercom circuit.
