    UK - Cadac Holdings Ltd., Luton, Beds. UK. At this year’s Prolight+Sound exhibition Cadac is expanding its MegaCOMMS audio network with the launch of two new hardware network components, alongside a major software package for CDC MC Router – the hub for a MegaCOMMS audio network.

    The new hardware components consist of the CDC MC Optical Bridge and the CDC MC AES3 Stagebox which both add another level of flexibility to the MegaCOMMS network. Cadac’s MegaCOMMS is already the audio industries lowest latency networking protocol, with a total through-system propagation delay, including all console processing and A-D / D-A conversions of an astonishing 37 samples (@ 96 kHz), or just under 0.4 milliseconds.

    The 1U CDC MC Optical Bridge allows 128 channels of 24-bit / 96 kHz of MegaCOMMS audio to run on an optical cable for up to a distance of 2 km (6,561 feet) with a latency of 0.02 milliseconds. This distance is from bridge to bridge, but a further run of up to 150m on RG6 coaxial from the bridge to the console or stagebox, or even another CDC MC Optical, can be added. The unit has four pairs of MegaCOMMS ports – transmit and receive - with a duplex optical multi-mode / single mode LC port per pair, allowing up to 512 channels of audio to be transmitted. Each of the MegaCOMMS pair is independent allowing complete flexibility in its application.

    The 2U CDC MC AES3 Stagebox provides a total of 18 AES3 inputs / outputs via four, 25-way D-Sub connectors and two XLR connectors, making a total of 36 audio inputs and outputs. All of the inputs, which are transformer isolated, and outputs have SRC on a connector to connector basis; 44.1 kHz, 48 kHz and 96 kHz (192 kHz on inputs only) with conversion to 96 kHz. The unit can also be synchronised with an external Word clock (3V3 and 5V0), AES11 or via its own internal clock. 

    As with all CDC MC units these feature redundant power supplies as standard and MegaCOMMS ‘port illumination’; red for receive and blue for transmit, a boon for low light set-ups.

    The new CDC MC Router (Windows 10™) software application gives the ability to end users to create their own CDC MC Router maps from an intuitive graphical user interface. The Router will auto detect the attached MegaCOMMS units whilst the software interface will show the individual unit’s MegaCOMMS connectivity capabilities, along with the units firmware status and will highlight any incompatibilities between versions (making an ideal pre-show diagnostic tool). 

    The software provides granularity of the routing options; from auto patching or patching in blocks to individual patching of sockets. The choices of how to patch will enable the creation of large scale audio networks – which with MegaCOMMS can extend to 3072 channels – in a very short space of time and allow rapid re-patching as applications change. 

    Another key feature of the Router is its ability handle the gain compensation between consoles. The Router automatically compensates for any adjustment in gain from the master console without affecting the gain, or audio quality, of any other console in the same network. 

    Richard Ferriday, Cadac’s Sales and Marketing Director, says, “These new products are a great addition to our current range of MegaCOMMS units, which include stageboxes and the CDC MC MADI and MC Dante network bridges. With the flexibility of the MC Router, combined with the incredible latency figure for the network, plus the audio performance and ease of use of our consoles, we believe we have something quite unique to offer the professional audio market.”

    About MegaCOMMS

    Cadac CDC MegaCOMMS’ unique latency performance is married with absolute phase coherence, the result of complete sample synchronization before summing, to provide exemplary audio performance in a digital audio network, capable of transmitting up to 3072 channels of bi-directional 24-bit / 96kHz audio, control data and clock, on up to 150 metres of RG6 cable, or up to 2 km on fibre optic.
