CDC I/O 6448

  • Overview

    The CDC I/O 6448 is an 11U fixed configuration stagebox featuring 64 highly acclaimed Cadac mic-amps and 48 analogue XLR outputs. The stagebox is connected to the console using Cadac’s MegaCOMMS network protocol allowing the I/O unit to be located up to 150 meters from the mixer. The CDC I/O 6448 has dual MegaCOMMS send and receive ports on the rear for redundancy.

    The Cadac mic-press can be controlled remotely from the console along with output assignments. To complete the user interface there is signal present, clip and phantom power indication plus mute indication for the outputs. Larger networks can be created by using the MegaCOMMS CDC MC Router which can connect up to 12 MegaCOMMS devices within one network.

    For that extra peace of mind there is also the option for adding an additional power supply to safe guard against PSU failure.

    Feature Summary

    • 11U fixed configuration
    • 64 Cadac mic / line inputs
    • 48 line outputs
    • Dual pair of MegaCOMMS ports
    • Redundant power supply option


    Cadac’s MegaCOMMS digital network allows the audio infrastructure to be designed to meet the requirements of the most challenging applications. With a choice of local I/O cards, stageboxes and audio network bridges plus a dedicated router to handle the dynamic management of the audio, the network can be as complex or as simple as required. 

    All Cadac digital audio is transmitted using Cadac’s proprietary MegaCOMMS digital interconnect protocol which provides less than 0.4 ms latency from analogue input on stage, through the CDC eight or CDC six, to analogue output on stage, plus robust error correction and advanced system clocking.

    The protocol provides up to 128 bi-directional channels of 96 kHz / 24-bit audio along with all control data and clock synchronisation. This is all carried on co-axial cable with runs of up to 150 meters (492 feet) from the console or MC Router. The benefit of combining audio, control, and clock into one single network simplifies connectivity, shortens set-up time and reduces investment in cabling infrastructure.
