The KA auditorium was the first theatre space to have speakers built into every one of the 1950 seats. There are more than 5000 speakers throughout the installation.
The soundtrack for the show is performed live by 8 musicians, who are situated in two soundproof studios backstage.
The largest strung musical instrument in the world is situated in the entrance to the show – the Earth Harp was designed by William Close and is played 15 minutes before the show begins by a performer above the entering audience.
There are ten ‘stages’ used by performers, but none of them are visible when the audience enter – they can only see the void – a huge empty space belching fire and smoke.
- Sand Cliff Deck (automated)
- Tatami Deck (automated)
- Downstage Lift
- Stage Left Lift
- Stage Right Lift
- Single Lift for Turtle
- Passarelle (fixed walkway 3.5 feet wide at the front of the auditorium, at the edge of the void)
- Auditorium Structures
- Auditorium Aisles
Automated Stage – The Sand Cliff Deck
50 foot x 25 foot ( in metres) 6 foot thick deck, used throughout the show as a ship, a cliff and a sandy beach. It weighs 80,000 pounds and has a 72 feet range of vertical movement. It’s supported and controlled by a customised gantry crane, attached to four 75 foot long hydraulic cylinders (two on each side). The gantry crane weighs 200,000 pounds. The crane assembly had to be lowered into position through the roof of the theatre during construction. For environmental reasons, the hydraulic cylinders use vegetable oil rather than traditional hydraulic fluid. The stage surface is a multi-touch sensor and has three projectors mapped to it, so that whatever orientation the stage is in, the projection stays locked to it. It can rotate 360 degrees at speeds of up to 12 degrees per second, whilst simultaneously tilting up to 100 degrees.
There are three high quality projectors overlapping to create the required brightness. A computer system connects between the touch sensitive stage surface and the projectors to display appropriate images as required by the story.
The deck also includes three elevators built in which are used early in the show, and 80 steel pegs which can be triggered individually, to provide handholds for the acrobats. The pegs are fired out of the deck at a speed of 13 miles per hour.
Automated Stage – The Tatami Deck
30 feet x 30 feet. Was originally to be covered in Tatami mats, but that was changed during the pre-production phase. Weighs 75,000 pounds (34,000 kg). Slides 36 feet forward over the void. Runs on two electric motors and uses a hydraulic braking system.
The world’s largest air bag is positioned at the bottom of the void, measuring 65 feet x 46 feet and is 5 feet thick. In addition, acrobatic safety nets are used.
As well as the automated decks, the set also contains 14 corrugated steel tubes, which represent trees. These travel across the stage, hung from large tracks.
