Shure DIS
  • DIS-CCU Central Control Unit  
  • General Description

    The DIS-CCU Central Control Unit is the centerpiece of the DDS 5900 Digital Discussion System and the DCS 6000 Digital Conference System. It distributes digital audio, control data, and
    power to chairman, delegate, and interpreter units over a standard shielded CAT 5e (or higher) cable in serial ‘daisy-chain’ topology using the proprietary DCS-LAN protocol.


    The DIS-CCU includes 2 analog audio inputs for external audio sources, and 8 analog audio outputs for connection to a videoconferencing system, audio/video recorder, sound reinforcement system, or wireless language distribution system.

     

    The DIS-CCU distributes the ‘floor’ audio mix plus interpretation channels to each discussion or conference unit. Up to 8 microphones may be active simultaneously. Four different microphone operating modes are supported: Automatic, First-In/First-On (FIFO), VOX (voice activated), and Manual.


    A web browser interface allows microphone control and system configuration using a computer or tablet. Separate web addresses are provided for Administrator, Chairman, and Display functions.A TCP/IP connection is provided for connection to a third-party media control system.
