RTS 4ch Expansion Master Station with 4.0 Amp Power Supply - EMS-4001
The EMS-4001 adds four (4) powered intercom channels to an MS-2002 or MS-4002 Master Station, and it provides talk, listen and call buttons for the added channels. Up to four (4) EMS-4001 Expansion Master Stations may be connected to the MS-2002 or MS-4002 to can add up to 16 channels (20 channels total). The MS-2002 or MS-4002 microphone is used to talk back to the EMS-4001 channels, and the MS-4002 speaker is typically used for listening. However, there are also separate speaker jacks on the back panel of the EMS-4001 for independent monitor speakers, if desired. There are also four (4) additional program inputs on the back of the EMS-4001, one for each added channel.
Features
- Simplified Expansion–The EMS-4001 integrates four (4) powered channels with talk, listen, and call controls in a
single rack mount unit. Saves on rack mount hardware and eliminates power supply to expansion station interconnect cables. - Compatibility and Flexibility–Connects directly to an MS-2002, MS-4002 or US-2002 Master Station to add four (4) complete powered channels. Or connects to a previous EMS-4001 or ES-4000A Expansion Station to add another four (4) powered channels (up to 20 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 its 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 masterstation 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 right or left speaker.
- Instantaneous Auto-Reset–Instantaneous Auto Reset (IAR), the newest technology in performance and safety, which uses a revolutionary new circuitry that dynamically monitors line fault conditions. Then, when the fault is removed, automatically brings individual power supply channels up.
