London, 2012

The first city to host the Olympic Games three times, the London 2012 Olympic Opening Ceremony is regarded as one of the best ceremonies ever created.

Loudspeaker System

The loudspeaker system was designed by Scott Willsallen with rigging and engineering designed by Wonder Works. The system consisted of 22 flown arrays each consisting of 10 L-Acoustics VDOSC, 22 ground stacked arrays of 4 L-Acoustics KUDO and 4 SB28 subs. Each of the flown arrays had a small down-fill array of ARCS II to provide lower bowl coverage during Athletics when the ground stacked systems were removed.

Audio Control System

The audio control system is designed around 100% dual-redundancy in all control system elements. The signal transport network is based on an Optocore main network and an analog backup network. The Optocore system connects to the main consoles via MADI with DiGiCo SD racks connecting to the backup consoles, also via MADI, allowing the main and backup pairs of consoles to be mirrored. The signal transport network used 16 field nodes to deliver audio to the FOP and flown loudspeaker arrays.

Audio Replay System

The audio replay system was a dual-redundant pair of Merging Technologies Pyramix systems. Each system consists of a purpose-built rack mount Windows PC with the proprietary Mykerinos card delivering MADI to the distribution system. Two separate word clock universes are maintained for redundancy and both replay systems are delivered to all consoles using DirectOut MADI SRC units.
