Description

The MS-2002 is a complete 2-channel master station and system power supply (24 V DC, 2 Amps total power) in a
single unit. You 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 even has both 1-channel and 2-channel
connectors, so you don’t have to add a separate breakout box if you want to mix 1-channel and 2-channel intercom
stations. The MS-2002 fits in a standard 19-inch equipment rack and is 1 rack unit high. The basic MS-2002 can
communicate with two intercom channels. This number can be increased by connecting optional EMS4001Expansion
Stations. Each EMS4001 adds four additional channels, and up to four of these expansion stations can be connected
for a total of eighteen channels.
