CHAPTER 1
Introduction
Description
The MS-2002 is a complete 2-channel master station and system power supply (24VDC, 2Amps 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
back panel, and you’re ready to communicate. It has both 1- and 2-channel connectors, so you do not have to add a separate
breakout box if you want to mix 1- and 2-channel stations. The MS-2002 fits in a standard 19-inch equipment rack and is one
(1) rack unit high. The basic MS-2002 can communicate with two (2) intercom channels. This number can be increased by
connecting optional EMS-4001 Expansion Stations. Each EMS-4001 adds four (4) addition channels, and up to four (4) of
these expansion stations can be connected for a total of 18 channels.

1. Dynamic-Mic Headset Connector - Accepts headsets with
monaural headphones and either a balanced or unbalanced
dynamic microphone.
2. Panel Mic / Electret-Mic Headset Connector - Accepts an
electret gooseneck microphone, such as the Telex Model

connector is a 1/4” stereo plug, with a threaded shaft for easy
installation.
3. Vo lum e Con t rol - Adjusts headphone volume only.
4. VOX Trimmers - Used with the voice-activated microphone
feature. Separate trimmers adjust the voice activation level
for the headset and panel microphones.
5. Headset and Panel Mic Keys - Used to manually activate
either the headset or panel microphone, whichever is being
used.
6. All Talk Key - Used to talk to all stations that are listening on
all channels. This includes both MS-2002 channels and all
channels of any connected EMS-4001 Expansion Stations.
7. PA K ey - If the MS-2002 is connected to a public address
system, this key may be used to talk over the public address

used, volume must be adjusted at the external speaker.
13. Combine / Isolate Switch - This recessed, push-button
switch lets you combine the audio signals of the two (2)
channels to create a single audio channel where all users can
intercommunicate. Or, you can isolate each channel to create
two (2) groups of completely independent users. For normal
operation, it should be set in the isolate position.
14. Channel Status Indicators and Reset Push-buttons - The
indicators are green for normal operation and red when there
is an overload or short circuit. The Reset push-button
restores normal operation after the short-circuit or overload
has been located and fixed.

input power in the range of 100-240 VAD, 50/60 Hz.
16. 2-channel Intercom Cable Connectors - One (1) male and
one (1) female XLR-6 connector for 2-channel operation
with SS2002, BP-2002, etc.
17. Program Inputs Connector and Trimmers - Each intercom
channel has its own program input and level adjust trimmer.
The program inputs may be turned on or off via the front
panel and they may be set to interrupt during talk, if desired.
18. 1-channel Intercom Cable Connectors - Two (2) connectors
are provided for each channel for loop-through connection of
1-channel intercom stations, such as the SS-1002, BP-1002,
etc.
19. PA O ut pu t - Connects to a public address system.
20. Expansion Out Connector - Connects to an EMS-4001
Expansion Station.
21. Speaker Output Jacks - May be used with external, powered
loudspeakers for monaural or binaural listening
configurations.
22. Balanced / Unbalanced Selector Switches - The selector
switches sets the MS-2002 for compatibility with either
Audiocom or Clear-Com channel connector pin-outs,
channel power requirements, and call signaling
requirements. Both switches must be in the same position.
