Sound and communication systems specialist, Orbital Sound supplied the sound system for Sadler's Wells' recent premiere of The Most Incredible Thing.
The work is a narrative ballet with a contemporary score written and recorded by The Pet Shop Boys.
Sound design was by Olivier, Drama Desk and Tony Award-winning designer Paul Arditti.
Arditti centred the system around the d&b audiotechnik T-Series T-10 line-array, putting together the spec for a top-end system that could also cope with later plans to tour the ballet.
The main system is configured with four hangs of eight T-10s, each with a T-SUB, plus a centre cluster of ten T-10s, with the addition of four d&b Q-Subs and four B2s to boost the low end performance.
The delays and front-fills were predominantly L-Acoustics MTD108As, augmented by a couple of d&b E9s to cover the middle of the expansive upper circle.
Use was also made of some of the in-house Control 1 delays that were already in place to cover the furthest reaches of the circles.
The surround system comprised forty d&b E0s. Matrix routing, delay and EQ was on a Yamaha DME64, while a pair of Mac Pros running QLab in 'Guaranteed Sychronisation' mode was used for playback.
