Sound reinforcement for Friday's London 2012 opening ceremony in the Olympic stadium was delivered through the classic line array staple, the V-DOSC system, featuring Wavefront Sculpture Technology, designed by Paris-based L-Acoustics.
An estimated 220 V-DOSC line source cabinets were flown for the London event, supplemented by over 50 ARCS downfill cabs. Reinforcement at ground level was supplied by around 80 L-Acoustics SB28 subs, with additional frontfill from (estimated) 80 KUDO cabinets.
The L-Acoustics system was rigged especially for the opening ceremony; the installed PA system in the 80,000-capacity stadium has been identified as over 100 Electro-Voice EVH horn-loaded co-axial speakers from the EV Innovation series (pictured).
Over one billion people worldwide are believed to have watched the opening ceremony, which featured spectacular and humorous sequences starring Daniel Craig as James Bond, Rowan Atkinson as Mr Bean, a cast of thousands of volunteers and HM The Queen herself. The soundtrack was put together by techno overlords Underworld.
