Studio Technologies Model 370A 2-Channel Intercom Beltpack
Studio Technologies Model 370A 2-Channel Intercom Beltpack The Studio Technologies Model 370A Intercom Beltpack begins with the features offered by traditional 2-channel party-line 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 370A 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.
