EMS-4001
Expansion Master Station
The EMS-4001 adds four 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 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 4 additional program inputs on
the back of the EMS-4001, one for each added channel.
Simplified Expansion
The EMS-4001 integrates four powered channels with talk,
listen, and call controls in a single rack mount unit. Saves on
rack mount hardware and eliminates power supply to expan-
sion station interconnect cables.
Compatibility and Flexibility
Connects directly to an MS-2002, MS-4002 or US-2002
Master Station to add 4 complete powered channels. Or
connects to a previous EMS-4001 or ES-4000A Expansion
Station to add another 4 powered channels (up to 18-20
channels total).
Overload/Short-Circuit Protection
Provides automatic current limiting during short circuits or
overloads. Front panel fault indicator provided for each chan-
nel. The SPS-2001 has Instantaneous Auto Reset (IAR), the
newest technology in performance and safety, which uses
a revolutionary new circuitry that dynamically monitors line
fault conditions.
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. Con-
nect any line-level audio source for monitoring in the master
station’s speaker or headset and for routing to the expan-
sion 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
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.
