China’s first-ever BMW Group Night, held at the Shanghai World Expo Exhibition & Convention Center, saw the German automobile company unveiling the latest model in its electric vehicle series, the BMW iX SUV, with sound engineer Jin Shaogang specifying an L-Acoustics L-ISA immersive sound configuration supplied by Hangzhou Das Wumei Technology Co.

To accompany the most technologically advanced model in the manufacturer’s lineup, BMW called on the most advanced production technology. A 120-meter-deep stage, surrounded on three sides by LED screens was created for the spectacular event visuals. In addition, Academy Award-winner Hans Zimmer was invited to create an electronic soundtrack to accompany the iX debut.

Shaogang designed the 360-degree sound system for the event, with a configuration consisting of five hangs of eight L-Acoustics Kara spread across the stage area, while nine arrays of two L-Acoustics A10 — one Focus and one Wide each — surrounded the sides and back of the audience. Six KS28 subwoofers per side provided low-end rumble, and eight X15 HiQ ensured onstage monitoring. The loudspeakers were powered by 24 LA12X amplified controllers.

On the large stage, the electric purr of the BMW iX would provide little sonic impact, so in order to give the audience the visceral feeling of being inside the iX, Shaogang captured 360-degree surround recordings of the BMW iX engine and its movements with the assistance of L-Acoustics Asia Pacific Director of Application Project Alvin Koh. For the live show, the onstage iX was equipped with a BlackTrax infrared sensor for real-time tracking. Integrated into the L-ISA Controller, the BlackTrax movements triggered the engine sound recordings in real-time with the onstage car.

“The natural and vivid experience of L-ISA Immersive Hyperreal Sound, elevated the show to greater heights,” explains Koh of L-Acoustics. “Thanks to the astute technical vision of Mr. Shaogang, and the collaboration between various partners involved in this show, we were all proud to present a brilliant dual-sensory show for BMW and the audience.
