The use of the CDC MC MADI allows connection to a MADI network.
The 1U unit can operate at 96 kHz or 48 kHz and can handle up to 64 inputs and outputs and is equipped with 128 channels of SRC as well as its own independent word clock.

MegaCOMMS is Cadac’s proprietary digital audio protocol.
MegaCOMMS is a robust, TDM (time division multiplex) system. Control data is embedded within the data stream, so that no audio channels have to be sacrificed for this purpose. The high bandwidth available means that the current implementation of MegaCOMMS can carry 128 channels of 24-bit, 96 kHz audio, plus control data, plus clock, bi-directionally, up to 150 metres via a pair of RG6 coaxial cables.
Cadac specify RG6 75 Ohm 18 AWG solid bare copper, super high-resolution coaxial to ensure that the cable is capable of handling over 4 times the data required for MADI.
The glowing connectors on the rear of the console and on the rack mount units are MegaCOMMS ports.
The red – Rx – connectors are the receive or “in” ports and the blue – Tx – connectors are the transmit or “out” ports.
RG6 is a very robust cable and the BNC connectors used are professional grade connectors and we are not limited to 100m runs of Ethernet technology – MegaCOMMS will easily run up to 150m on coaxial.
No – unless the cables you are using are RG6 75 Ohm 18 AWG solid bare copper, super high-resolution coaxial.
MegaCOMMS requires a cable that is capable of handling over 4 times the data needed for MADI.
