L-Acoustics Used for Red Bull Event

High-end aerobatic planes weren’t the only things that took to the skies at downtown San Diego, Calif.’s Big Bay for the second-to-last stop of the 2007 Red Bull Air Race World Series. Numerous L-Acoustics line source array elements were also flying at five different locations along the north and south peninsulas of Embarcadero Marina Park.

Hayward, Calif.-based Sound on Stage was contracted as the exclusive sound reinforcement provider for the race. According to general manager George Edwards, “The benefit of using L-Acoustics line arrays and various boxes in this particular application is two-fold. First is its proven ability to cover wide and long distances, and second is the absolute clarity of the spoken word. This is a unique event. There is no stage; it’s not about entertainment. The whole thing is about taking the announcer’s voice from one microphone and distributing it cleanly to a 100,000 people or more.”

Getting that single microphone’s message out loud and clear was a combined total of 16 ARCS, 28 dV-DOSC and six V-DOSC line source array elements, plus four high-power dV-SUB and 14 SB218 subwoofers, all spread out between five SR positions.
