Capital Sound has bolstered its Optocore system with six additional XR6-FX converters for the AEG-Barclaycard British Summer Time 10-day season at London’s Hyde Park, which included performances by The Rolling Stones and Bon Jovi. Capital Sound had been awarded the sound reinforcement contract by promoters AEG Live/Loud Sound earlier this year, and spoke to PSNEurope exclusively about it at Prolight + Sound in Frankfurt. The London-based production company deployed the Optocore system that they purchased in 2011 for the Take That Progress Live stadium tour. The additional six X6R-FX-8AE/8MI converters – in addition to the eight already in its inventory – enabled Capital Sound to connect to 11 locations as well as dual redundant units at FOH (plus back-up). Configured with 8-channel AES3 I/O 8-channel microphone inputs and wordclock I/O this provided the capability of 32-channel AES-EBU output. The redundant units at the FOH tower connect to these remote locations – including nine delay towers, VIP stand and second FOH tower (for lighting control) via the fibre network, carried on catenaries and delivering AES-EBU audio feeds. Connectivity to the Martin Audio PA’s MLA VU Net control network, running the dedicated Merlin management system, was via an Ethernet tunnel – with RS485 data connection to the XTA DP-226 processor ports located in the VIP stand and at the FOH tower.

Capital Sound technical manager, Ian Colville commented: “Optocore was the only transport system that would allow us to create a complete redundant loop over this distance with no hums and buzzes. Nothing on copper comes close – and in any case you can't suddenly extend the network by another 200 metres if you realise you need it, as you can with fibre. This solution gives us complete isolation.” www.optocore.com
