Historic Chinese install for Renkus-Heinz20 July 2009
Now said to be the largest LED screen in the world at 350,000sqm, the installation sits above a vast shopping complex that includes food, beverage, retail and entertainment outlets. The Skydome is illuminated by an array of Keyframe-programmed visual effects, including moving blue skies with clouds and a piano keyboard.
To satisfy the demand for an audio system that synchronises at street level with the images moving along the 500m-long screen, Beijing Zhongguang Radio & TV Engineering Installation Corporation installed a 106-channel surround system featuring 106 Renkus-Heinz STX-7/44AS-WR high-power weather-resistant loudspeakers. Some 38 DRS18-2BW dual 18in weather-resistant subwoofers act as the principal audio source.
Power comes from 160-plus Camco Tecton Series amplifiers, equipped with UCA-T-AN cards that enable the WINCAI (Camco Amplifier Interface) audio management system. These cards allow both complete system management and local signal processing adjustment via each amplifier’s UCA controller modules. Camco’s CISUS software provides remote operation of the CAI audio network management control software through each amplifier’s RJ-45 interface.
Equipment for the prestigious project was supplied by Foshan Tian Chuang Zhongdian Trading Co Ltd.
Speaking to II, Renkus-Heinz vice president of international sales, Karl Brunvoll, noted the contribution of its distributor for China, TICO/CAH Professional Sound, and said that the manufacturer was “very excited to be associated with a project this complex and unique. I have been working in China for many years, and it is great to see how [the installation] companies are developing and becoming real technological powerhouses.”
Brunvoll added that he expects to see “significant growth” in China for the ICONYX series of digitally controlled column loudspeakers.
