World's Largest Solar Audio System Delivers 105dB To 40,000 Spectators

Earlier this month, Grzebik Design completed work on what they are calling the "world's largest solar powered loudspeaker system" in the Taiwan National Stadium in Kaohsiung. It is capable of cranking out 105 dB of sound to 40,000 spectators.

The Taiwan National Stadium makes use of 60 distributed Apogee Sound AE-7SX weather-resistant loudspeakers for primary seating area coverage, 12 Apogee Sound ALA-5WSX weather resistant Acoustic Linear Array loudspeakers provides field coverage, and 2 Apogee Sound AFI-205 and two AFI-Point5 loudspeakers provide Control Room audio monitoring. The 76 loudspeakers are powered by 52 Peavey Electronics model PV2600 and 3 model PV1500 power amplifiers. Additional signal processing equipment includes Apogee Sound loudspeaker controllers, Symetrix SymNet Digital Signal Processing equipment, an Altair 48-channel mixing desk, Tascam CD, DVD and cassette players, Peavey Electronics, microphones, and CUE Touch Panel Controllers, all wired together with 9,500 meters (5.5 miles) of Klotz Cable.

Naturally, going 100% solar with an installation like this requires a buttload of green tech:

The ultra-modern $US5 billion Taiwan National Stadium, designed by renowned Japanese architect Toyo Ito, and constructed for the 2009 World Games, features a stunning 14,155 square meter roof incorporating 8,844 solar panels, which emulates the form of a flowing river, and generates 1.14 million KWh annually preventing the release of 660 tons-per-annum of atmospheric carbon dioxide. On days when the Taiwan National Stadium is not in use, the electricity generated from its roof is fed back the city's electrical grid where it will meet almost 80% of the area's energy requirements.

Indeed, if you look at the images of the roof, it seems to be completely covered in "a flowing river" of solar panels. [PrthatRocks]
