E-V system in key Commonwealth Games venue2 November 2010
The largest venue to be used for the XIX Commonwealth Games – the Jawaharlal Nehru Stadium in New Delhi – features a permanently installed audio system from Electro-Voice.
The loudspeaker spec for the 60,000-plus (seated) capacity venue comprises 132 customised 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.
The system was designed by the EV team in Minnesota, US. The order to install and commission the system was placed with Bosch India, prompting a Bosch Security Systems spokesperson to tell IE that "strategically it was a very prestigious project for us as it announced the arrival of EV in India in a big way".
