    Ethernet hub are available on the rear panel; any of these may be used to connect the CDC seven to a computer, allowing multitrack recording and playback. The mixer may also be connected to a Waves MultiGrid server running Waves plug-in signal processing, with the control panels for the plug-ins presented on the CDC seven’s main screens.

  • Page 13: Data Protocol: Megacomms

    Data protocol: MegaCOMMS Communication between the remote MegaCOMMS I/O devices and the control surface is via a proprietary Cadac high speed protocol called MegaCOMMS, using high-speed 75 ohm coaxial cable terminated in BNC connectors. Two interconnection paths are provided, A and B, each of which requires a transmit and receive cable.

    Data communications: MegaCOMMS Cadac’s proprietary MegaCOMMS hi-speed data protocol is used to interconnect the CDC seven’s control surface and stage rack(s). The control surface and each stagebox each have four BNC sockets to provide the main system data interconnection, labelled TX A, RX A, TX B and RX B.

    Kramer bulk Type BC-1X. Word Clock In The CDC seven caters for digital audio I/O in the form of eight AES3 inputs and eight AES3 outputs, accessible on the rear of the control surface. The AES3 outputs have Sample Rate converters (SRCs) and can operate at any frequency required by applying an external clock source to the WORD CLOCK IN connector.

    – channel input, aux send, channel insert, matrix output, etc. – anywhere in the console’s architecture. It should also be noted that the overall I/O physical connectivity provided by the system is unrelated to the CDC seven’s maximum processing capacity of 96 simultaneous input channels mixing onto 48 assignable output busses.

  • Page 35: Main Screens - Touch Operation

    Main screens – touch operation All audio operations on the CDC seven are performed using the two main touchscreens. Each display shows sixteen consecutive virtual channel strips, and includes the most important information about the channels’ configuration and parameters. More detailed information and access to controls for any channel is obtained by a single touch on the appropriate area of the screen.
  • Page 36 2. Swiping – a “swipe” action horizontally across the screen will shift the displayed set of channels a number of channels proportional to the “length” of the swipe. This is a very powerful feature of the CDC seven, and allows very rapid access to channels not currently displayed.
