The Discerning Choice
For The Audio Professional
MegaCOMMS
Cadac’s MegaCOMMS digital audio network has been designed to meet the requirements of the most challenging applications.
Cadac's MegaCOMMS Protocol
MegaCOMMS allows total through-system propagation delay, from inputs on stage to outputs including all console processing and AD / DA conversions, in 37 samples (@ 96 kHz), or just under 400μs.
MegaCOMMS is a robust, TDM (time division multiplex) system and is clocked at 96 kHz, however SRC (sample rate convertor) is provided for other clock speeds.
Cadac CM-J50's MegaCOMMS interface: A and B ports on either BNC or LC optical.
The protocol provides up to 128 bidirectional channels of 96 kHz / 24-bit audio, along with all control data and clock synchronisation. This is all carried on a pair of coaxial cables (send and return) with runs of up to 150 meters (492 feet) from the console, or up to 2 km (6,561 feet) with optical cables. By combining audio, control, and clock into one single network simplifies connectivity, shortens set-up time and reduces investment in cabling infrastructure.
​
The CM Series network bridges allow MADI, with the CM-MD64 bridge, and Dante, via the CM-DT64, protocol-based products to be seamlessly integrated in to the MegaCOMMS network, allowing third party networks and hardware to make use of those superlative Cadac Mic-pres.
