ISE 2018: Cadac to launch audio location network
- Details
MegaCOMMS’ ‘total through-system propagation delay’ - from on-stage inputs to outputs (including all console processing, A-D / D-A conversions and three stage internal latency management) - is less than 400 microseconds (millionths of a second). Additionally, the MegaCOMMS protocol synchronizes all audio samples before summing, for absolute phase coherency at every output.
At the heart of the MegaCOMMS network is the software programmable CDC MC Router. The 2U 12 port MegaCOMMS router is a powerful tool for creating large, resilient networked audio systems, comprising up to 12 separate MegaCOMMS devices - including CDC mixing consoles and I/O stage boxes - and 1,536 bi-directional channels of 96kHz / 24-bit audio.
Devices connect to the CDC MC Router on the MegaCOMMS network via low cost, robust co-axial cables. More extensive networks, to distances of up to 2 kilometres, are achievable via fibre optic cable, with the MegaCOMMS CDC MC Optical Bridge.
Programmable control of the CDC MC Router is provided by the dedicated NetCOMMS PC software.
Cadac’s range of CDC digital mixers and multi-format I/O stageboxes provide production control in a MegaCOMMS network, with a choice of control configurations and channel counts.
“Cadac’s MegaCOMMS platform offers the system installation and event sectors an industry leading networking and mixing solution, dedicated to higher standards of quality and performance, and system reliability, for live production than other audio network solutions,” says marketing manager, James Godbehear. “NetCOMMS software provides a highly intuitive means of control, enabling even the most complex and demanding networks to benefit from Cadac’s MegaCOMMS superlative audio quality.”
The 2017 BRICS Xiamen Summit of the five major emerging national economies – Brazil, Russia, India, China and South Africa – saw the premier large scale deployment of a Cadac’s MegaCOMMS audio network, with a single CDC MC Router at the heart of a network – incorporating six CDC six console and CDC I/O stagebox mix systems – extending throughout the Xiamen International Convention Centre.
The MegaCOMMS network handled all audio transmission, with audio feeds networked to KLING & FREITAG speaker systems at the various locations across the site, as well to international media organisations.
