The Shure 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. In standard DDS 5900 mode, it powers up to 60 microphone units and supports up to 250 units. The unit also supports 2 languages and 32 interpreters. With Feature License FL6000, the DIS-CCU can be used with DCS 6000-series microphone units serving up to 250 participants and 4 languages. Additional Feature Licenses enable support for up to 3,800 participants, 200 interpreters, and 31 languages.
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.
