The EMS-4001 adds four powered intercom channels to an MS-2002 or US-2002 Master Station. It connects to the master station with a supplied patch cord. Then, you simply plug it into any AC pwer outlet from 100 to 240 volts, connect intercom stations to the back panel, and you're ready to communicate on four more channels using the master station microphone and speaker or headset. the EMS-4001 fits in a standard 19-inch equipment rack and is 1 rack unit high.
Simplified Expansion-Integrates four powered channels with talk, listen and call controls in a single rack mount unit.
Compatibility and Flexibility-Connects directly to an MS-2002 or US-2002; or to a previous EMS-4001 or ES4000A expansion station to add another 4 powered channels (up to 18 channels total).
Overload/Short-circuit Protection-Provides automatic current limiting during short circuits or overloads. Front panel fault indicator provided for each channel.
Mic Kill-Turn off all microphones on a selected expansion channel or all channels using the master station's Mic Kill key.
Dedicated Program Inputs-Each expansion channel has it's own program input. Connect any line-level audio source for monitoring in the master station's speaker or headset and for routing to the expansion channel if desired. When program audio is routed to the channel it can be set to interrupt while the master station operator is talking on the channel.
Binaural (Stereo) Listening-If the master station is equipped with external powered speakers you can assign the EMS-4001 channels to either the right or left speaker.
