Overview

The MS-4002 is a complete 4-channel, balanced audio master station and 3.6 Amp system power supply 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. The MS-4002 is now equipped with an advanced programming mode on the front panel, eliminating the need for internal DIP switches.

Features

• Auto-Sensing Headset Connector
  The MS-4002 has a built-in autosensing headset connector that will determine automatically whether a dynamic or electret headset is connected to the system.
• Speaker Station or Headset Station
  Use the built-in speaker for listening and add an optional MCP-90 series Gooseneck Panel Microphone for talkback. You can also turn off the speaker volume, and plug in a headset for private communication.
• Voice Activated Microphone (VOX)
  Separate 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.

• 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-4002 operator is talking on the channel.
• Listening with External Powered Speakers
  You can connect external powered speakers and then monitor channels 1, 2, 3 and 4.
• Expandable
  Add more channels by connecting optional EMS-4001 Expansion Stations. Each EMS-4001 adds four additional powered channels (up to twenty channels).
• 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.
