K1/K2 system has it covered at the Bird’s Nest
Jason Zhang Jie (张杰) is a musical phenomenon in China and his latest Future Live tour has filled stadiums across the nation, including a show at the Beijing National Stadium (Bird’s Nest) for 80,000 fans. The Future Live show has been termed a ‘comprehensive showcase of new technology’, with the use of a large L-Acoustics K Series PA system as well as a huge ‘ice’ LED screen, advanced mechanical staging and lighting effects. Mr. Zhang Jing was the Monitor Engineer for Future Live and describes the evening at the Bird’s Nest Stadium as an ‘undreamed of success’. “It was mind blowing,” he says. “With spectacular lighting, and an amazing sound system. Zhang Jie delivered the best performance on stage, while the L-Acoustics system delivered the ultimate sound. The coverage was excellent, which is never easy for such a large-scale production, with audiences in the tens of thousands.” China’s Beijing National Stadium, nicknamed the Bird’s Nest Stadium due to its unique and highly recognizable architecture, includes a huge concrete inner bowl and a 45,000 tonne steel mesh roof.
Measuring 330m x 220m, even with the inner acoustic membrane, the sheer size of the venue meant that coverage and control were always prime concerns for the crew. The solution was a substantial L-Acoustics K Series deployment comprising over 200 loudspeakers. The main PA system consisted of stereo hangs of 12 K1 cabinets with three Kara modular cabinets, stereo hangs of 12 K1-SB subs, LR stacks of eight SB28 subs, and eight stacks of three Kara cabinets as distributed front fills. Two hangs of eight K1 and three K2 were used for outfills, and additional distributed systems consisted of five stacks of four K2 elements on chariots, plus two flown arrays of six K1 and three K2, and six flown arrays of eight K2 elements. “We definitely got the most out of the system,” says Zhang Jing. Zhang Jing. “We achieved the full fidelity the loudspeakers are capable of, which allowed us to maximize the listening experience for the audience. “With a well-designed solution and accurate installation, L-Acoustics gives excellent quality sound and creates a perfect atmosphere for the audiences – even in such a large venue.”
