The MS-2002 is a complete 2-channel master station and system power supply
in a single unit. You 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 even has both 1-channel
and 2-channel connectors so you don't have to add a seperate breakout
box if you want to mix 1-channel and 2-channel intercom stations. The
MS-2002 fits in a standard 19-inch rack and is 1 rack unit high. |

Features |
- Speaker Station or Headset Station-Use the built-in speaker for
listening and add an optional Telex MCP-90 series gooseneck panel
microphone for talk-back. Or, turn off the speaker volume and plug in
any of a variety of Telex headsets for private communications.
- Voice Activated Microphone (VOX)- Seperate controls adjust the voice
activation level for the headset microphone and panel microphone inputs.
- Public Address (PA) Output with PA key-Use your intercom microphone
to talk over a PA system.
- Back-lit Keys-Improves visibility in low-light.
- Incoming Call Indications-Red flashing call light with beep tone if
desired.
- Mic Kill Key-You can turn off all microphones on a channel to
quickly clear the channel.
- Program Input for Each Channel-Connect any line-level audio source
for monitoring in the speaker or headset or for routing to the intercom
channel. The program audio to the channel can be set to interrupt while
the MS-2002 operator is talking on the channel.
- Binaural (Stereo) Listening with External Powered Speakers-You can
connect external powered speakers and then monitor channels 1 and 2 as
seperate right and left audio.
- Expandable-Add more channels by connecting optional EMS-4001
Expansion Stations. Each EMS-4001 adds four additional powered channels
(up to eighteen total).
