The Rock Candy Festival, an inaugural festival featuring a two-day outdoor concert, saw the use of L-ISA immersive sound technology for the first time at an open-air festival in China.
Sound designer He Biao noted that the challenge of the installation was to gain enough height to achieve even sound coverage across the hilly audience area.
The solution was to position seven cranes across the stage area to support the main rigging trusses, as well as five hangs of L-Acoustics K2 for the main L-ISA scene system.
The system, deployed by Dadong Huahan, consisted of five hangs of 10 L-Acoustics K1 over six K2, augmented by two extension hangs of 15 K2 per side. Two centre-flown hangs of 12 K1-SB subwoofers with a further 28 KS28 and 32 SB28 subwoofers ground-stacked in front of the stage for low end rumble. Eight stacks of three Kara were spread across the stage as front-fill, while out-fill consisted of an array of nine K2 per side. A delay system of two hangs of 10 K2 each assured sound to the back of the audience area. Seventy-eight LA12X and 24 LA8 amplified controllers drove the massive concert sound system.
He Biao provided on-site support to the artists’ sound engineers who mixed their shows using two DiGiCo Quantum 7, one Quantum 5 and one Quantum 338 digital mixing consoles.
