India - With a 60,000-plus seating capacity, Jawaharlal Nehru Stadium in New Delhi is the biggest venue used for the October, 2010 XIX Commonwealth Games. The stadium hosted athletics events and, most importantly, served as the venue for the Games' opening and closing ceremonies. The stadium is equipped with an audio system from Electro-Voice
The EV loudspeaker spec at Nehru Stadium comprises 132 customized XLC127DVX (line-array), 120 Sx300PI, 300 EVID 6.2, and 60 ZX5-60PI surface-mounted systems, all driven by a combination of 135 P3000RL and TG amplifiers to deliver an average of 107 dB and a peak of 115 dB. The entire system is remote-controlled and supervised from a single laptop in the stadium control room, all via EV's IRIS-Net software platform. The system's Auto Gain Control increases or decreases the sound levels consistent with changes in the level of ambient crowd noise.
All external speakers are manufactured to exceed the IP55 standard for weather resistance, while the system's speech intelligibility surpasses the approved standard of 0.55 RASTI.
