Pro Intercom MS301 3 Circuit Intercom and IFB Master Station

Pro Intercom MS301 3 Circuit Intercom and IFB Master Station The MS301 is a 3-circuit Master Station with a unique hybrid configuration. Microprocessors operate all the switching, routing, and supervision functions while both the audio path and the core power supply remain analog. The result is a station with unrivaled flexibility, muscular reliability, and clean, smooth audio. Key Features Three circuits rather than the usual two Each circuit can be intercom or IFB in any combination Circuits are linkable (A + B) or (A + B + C) with auto termination impedance adjustment Each circuit's termination can be lifted via rear panel DIP switches Independent level control of program audio output for each circuit with an LED VU meter for each Mic switch on each circuit can be tapped for locking or held and released for momentary Internal power supply is linear (except for microprocessor functions) with 2.4A continuous output Toroidal transformer with extensive monitoring and auto-control of ov
