The Telex MS-2002 is a two-channel master station and system power supply offering easy interfacing of wired intercom stations and headsets in a 1 RU rack-mountable enclosure. With both 1- and 2-channel connectors, you can incorporate both types of stations without needing a breakout box. Separate jacks—each with its own adjustable voice activation level—are provided to accommodate headsets equipped with dynamic or electret microphones. Monitor through your headset, the built-in speaker, or via powered loudspeakers connected to the rear-panel RCA speaker jacks. The MS-2002's balanced/unbalanced selector switches ensure compatibility with Audiocom and ClearCom systems.
