Product Overview
Combining a single channel of talk and two channels of listen capabilities, Studio Technologies' Model 372A Intercom Beltpack is a highly compact user-worn device that starts off with the features you'll find onboard traditional analog party-line (PL) intercom user devices, then adds a range of newer capabilities, as well as the advanced performance and versatility that Dante® audio-over-Ethernet brings. Over a standard IP network, multiple Model 372A units and other compatible Studio Technologies' beltpack devices can be used to create party-line intercom applications with assistance from an external Dante-enabled audio matrix such as the Studio Technologies' Model 5422 Dante Intercom Audio Engine (sold separately). Alternately and additionally, these can be used "point-to-point" or interfaced with Dante-compatible matrix intercom systems too.
