Our loudspeaker system consisted of various parts to deliver specific elements of the show.
The L-ISA system received 96 inputs from the SD7 consisting of pre-mixed stems and mono objects from the Ovation replay system. The loudspeaker arrangement consisted of 34 outputs and a sub-bass output.
Our immersive system consisted of four parts:
Cube - originally designed as five arrays of three L-Acoustics K2, this was reduced to two arrays to enhance the view of the spectacular 15m cube.
Panorama - eight arrays of six K2 and one array of 18 SB28 subwoofers.
Surround - two arrays of nine KARA and 11 SYVA loudspeakers mounted beside and behind the audience.
Overhead - 11 X8 suspended overhead from the top of the lighting masts.
In addition to the L-ISA system we also deployed 180 L-Acoustics 5XT loudspeakers (1 for each guest) in a distributed mono arrangement which we used to deliver the dialog and narration. This technique allowed us to maintain the power and instrumentation in the music whilst also providing excellent speech intelligibility.
The L-ISA Control environment
The L-ISA session included 96 MADI inputs and 36 outputs. The inputs consisted of mono stems and solo instruments and mono sound effects objects, as well as a printed 7.1 sound effects package.
Audio control system
We used a mirrored pair of DiGiCo SD7 consoles with a pair of L-ISA Processors, one per console, connected using MADI. The signal distribution system consisted of multiple DiGiCo SD Racks for inputs and various Optocore network devices distributing the outputs to LA-Rack's around the venue.
Show Control Systems
We used a dual-redundant pair of Ovation systems by Merging Technologies operated by Steve Logan, probably the most experienced playback operator in the world. The system consists of a purpose-built Windows 10 computer running Ovation, the Horus audio interface delivering 128-channels via MADI and the Ovation keyboard for each system.
The people and companies that made it happen.
A huge thanks to Es Devlin and her design team, Jo Mackay and the whole team at LarMac for involving us in this project. Congratulations on delivering a really amazing project that was a joy to deliver.
The Audio system was designed by Scott Willsallen. Our team also included Richard Sharratt on FOH, Simon Sayer and Edoardo Michalori on replay and remote support from Justin Arthur, Luis Miranda and Steve Logan.
Thanks to Andy Jackson and his team from PRG Deltasound for supplying, installing and maintaining the system for us. Thanks to Toby Chester and Martin Dineley for their efforts in managing the PRG audio team.
