Olympic ceremonies: more audio details revealed

Production details of the Opening and Closing Ceremonies for the London 2012 Olympics came in drips before, and even during the Games. Now that the Olympic flame is headed to Rio, more pro-audio companies have been able to share the contributions they made to the spectacular events.   Heading the entire production was Australian company Norwest Productions, who worked closely with UK partners Delta Sound, Britannia Row and Autograph.   As it has been since the 2004 Olympics in Athens, Merging Technologies’ Pyramix was the DAW of choice for playback of the pre-recorded audio for the show (curated and programmed by UK dance act Underworld), driving broadcast and event timing with timecode output.   This year’s Pyramix system was expanded to allow 128 channels playback, the output from which was fed via two MADI streams into one of a total of nine DiGiCo SD7 consoles for all the ceremonies.   Delta Sound provided the necessary Optocore fibre signal transport, which took over three weeks to install, using more than 50 devices. Optocore also delivered both PA and monitor feeds, plus timecode and programme material. In total there were 696 I/O channel feeds within the Optocore topography.   The feeds were delivered via AES to a massive FOH PA comprising entirely L-Acoustics components, also supplied by Delta Sound (supplemented by European equipment ‘bank’ AED) with 220 VDOSC, 100 KUDO, 55 ARCS, 88 SB28 subs and a number of 12XT fills — all driven from 280 LA8 amplifiers; the largest Olympic PA system in the history of the Games.   Radio microphones for the ceremonies were Shure’s new Axient system, with Sennheiser G2s and G3s used for IEMs and a comms system provided by Riedel. We’ll have more from Riedel and the Olympics to tell you about, stay tuned to PSNEurope for details…     www.london2012.com
