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.

Simplied 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.
