Powersoft has contributed ultra-high-efficiency amplifier solutions that achieve approximately 40% energy savings compared to traditional amplifiers at Sphere, in Las Vegas.
Developed specifically for Sphere’s curved interior, Sphere Immersive Sound is powered by 167,000 channels of amplification provided by Powersoft’s compact 16-channel amplifier solutions, which are integrated into the Holoplot X1 audio system.
As well as the amplifiers integrated into the X1 matrix array, Powersoft provided its Integrated Powered Adaptive Loudspeaker technology for the system’s subwoofers.
Sphere’s 10,000 seats have also been integrated with Powersoft’s infrasound system. The company’s Powersoft Mover compact transducer uses haptic feedback to engage the sense of the audience beyond visual and audio stimulation. The moving-magnet technology relies on an ultra-low-frequency audio signal to make the seats vibrate.
To accompany the infrasound haptic system, Powersoft also supplied 2,500 audio channels for the seats, provided by 718 Powersoft Quattrocanali amplifiers.
David Dibble, chief executive of MSG Ventures, a division of Sphere Entertainment, said: “Sphere Immersive Sound has set a new standard in every aspect of live audio – and tens of thousands have already been immersed in its crystal-clear, individualised sound.
“And this past weekend, with the premiere of the Sphere Experience featuring Darren Aronofsky’s Postcard from Earth, guests, for the first time, experienced a truly multi-sensory haptic experience. Powersoft’s cutting-edge and energy-efficient technology made it the perfect partner to help achieve our sustainability goals without compromising audio or haptic quality.”
Powersoft’s president, Carlo Lastrucci, said: “Sphere is the largest-scale and most innovative application of Powersoft technology yet.”
