Description Description:

The MS-2002 is a complete 2-channel master station and system power supply (24VDC, 2Amps total power) in a single unit. Simply plug it into any AC power outlet from 100 to 240 volts, add a microphone or headset, connect intercom stations to the back panel, and you’re ready to communicate. It has both 1- and 2-channel connectors, so you do not have to add a separate breakout box if you want to mix 1- and 2-channel stations. The MS-2002 fits in a standard 19-inch equipment rack and is one (1) rack unit high. The basic MS-2002 can communicate with two (2) intercom channels. This number can be increased by connecting optional EMS-4001 Expansion Stations. Each EMS-4001 adds four (4) addition channels, and up to four (4) of these expansion stations can be connected for a total of 18 channels.


  • Dynamic-Mic Headset Connector – Accepts headsets with monaural headphones and either a balanced or unbalanced dynamic microphone.

  •  Volume Control – Adjusts headphone volume only.
  • VOX Trimmers – Used with the voice-activated microphone feature. Separate trimmers adjust the voice activation level for the headset and panel microphones.

  •  Combine / Isolate Switch – This recessed, push-button switch lets you combine the audio signals of the two (2) channels to create a single audio channel where all users can intercommunicate. Or, you can isolate each channel to create two (2) groups of completely independent users. For normal operation, it should be set in the isolate position.
  • Channel Status Indicators and Reset Push-buttons – The indicators are green for normal operation and red when there is an overload or short circuit. The Reset push-button restores normal operation after the short-circuit or overload has been located and fixed.
