Description
The MS-4002 is a complete 4-channel master station and system power supply (24 VDC, up to 3.5 Amps 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 backpanel, and it's ready to communicate. It has 1-, 2-, 3- and 4-channel connectors, so a separate breakout is not
needed to mix multiple intercom stations. The MS-4002 fits in a standard 19-inch equipment rack and is 1 rack unit high. The
basic MS-4002 can communicate with four intercom channels. This number can be increased by connecting an optional
EMS-4001 Expansion Station. Each EMS-4001 adds four channels, and up to four of these expansion stations can be connected
for a total of 20 channels.
