The Model 373A 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 373A 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 373A units can be used "point-to-point" or interfaced with Dante-compatible matrix intercom systems.
