Wigwam expands Optocore inventory for Coldplay tour

Wigwam Hire has enhanced its Optocore-based ‘OproRack’ data returns system in preparation for Coldplay's upcoming Mylo Xyloto arena tour, writes Paul Watson.

Wigwam Hire has purchased additional Optocore digital interfaces to prepare for the upcoming Coldplay European Mylo Xyloto arena tour, and next summer’s 2012 festival dates. Wigwam also handled Coldplay’s 2009 Vida La Vida tour, and has acquired a further five DD32R-FX interfaces, one for each of the five amp racks being deployed, all of which will be connected by fibre. “We will be running over 100 d&b D12 amplifiers in racks from five separate positions — some in the venue roofs and some on the ground; and programming in the delays,” explains Wigwam’s owner, Chris Hill (pictured, right). “All will be connected to our Optocore returns system.” Coldplay’s FOH engineer Dan Green and systems engineer Tony Smith feel that this purchase will provide them with a more elegant and stable solution. “The new DD32R-FX units offer a major advantage to running large scale systems such as we are deploying on Coldplay,” Hill says. “The ability to cable up to 700m between nodes when using multimode fibre transceivers — with network, audio, video and serial data available over the same fibre connections, as well as up to 24 nodes on the same network — really adds functionality to large scale systems.” The DD32R-FX digital interfaces offer further functionality, including 96 KHz AES audio and 100Mbit Ethernet transport across the whole network, enabling the transmission system to be built exactly to the requirement. “On the Coldplay tour, the DD32R-FX units will provide the ability to run 96 KHz AES audio via the FOH system EQ in the form of an XTA 548 — right through to the d&b D12 amps, which process AES audio at 96 KHz,” notes Wigwam’s digital specialist, Alex Hadjigeorgiou. “This solution will be equally applicable on smaller tours, such as The Saturdays later this year. It is a truly digital system: from the pre-amp on the DiGiCo SD stage box, right through to the amplifier, with only a single A/D and D/A conversion across the entire system, which will keep latency to the absolute minimum.” The Coldplay tour kicks off at the SECC in Glasgow on December 3.
