CDC I/O 3216

  • Overview

    The CDC I/O 3216 is a 4U fixed configuration unit featuring 32 mic / line analogue inputs and 16 XLR analogue outputs. The stagebox is connected to the console by using Cadac’s propriety low latency MegaCOMMS audio network protocol. The CDC I/O 3216 can be located up to 150 metres (492 feet) away from the console using just a pair of co-axial cables.

    The mic-pres can be controlled remotely from the console and the outputs can also be assigned from the console. To complete the user interface there are signal present, clip and phantom power indication plus mute indication for the outputs.

    Feature Summary

    • 4U fixed configuration
    • Provides an additional 32 Cadac mic / line inputs on stage
    • Provides 16 line outputs on stage
    • Single pair of MegaCOMMS ports


    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.
