Introduction
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.
