Human-powered flight has been a dream sought after for centuries and accomplished only very recently. Red BullÂ® gave contestants a crack at this rarely achieved fantasy during its summer-long Flugtag competition, held nationwide. In Long Beach, California, 105,000 spectators watched teams push whimsical contraptions from a pier, and the event sounded as good as it looked, thanks to the open-sourced approach to the next generation of digital audio networking, IEEE 802.1 AVB Bridging protocol, enabled by AVB-compliant technology from Harman Professional. The signal control chain consisted of four dbx SC 32 Digital Matrix Processors and 24 AVB-capable Crown CTs 3000power amplifiers, as well a half-dozen network bridge switches from BSS Audio/NETGEARÂ® configured and controlled using Harman HiQnet System Architectâ„¢. On Stage Audio (OSA), led by vice president Jim Risgin, deployed the AVB system.
The crowd at the Long Beach edition of the Red Bull Flugtag was so enormous
that the exit ramp off I-710 had to be closed, with all parking garages at full capacity and traffic gridlocked throughout the downtown area. The hundreds of thousands that secured a spot were rewarded with the spectacle of human flight as 34 teams launched their crafts off a 30-foot flight deck in an attempt to defy gravity (the international Flugtag flight distance record now stands at 207 feet and was set in Minneapolis/St. Paul on July 24, 2010). The sound system used for the event was less whimsical than the aircraft but surprisingly just about as simple. Using the HiQnet System Architectâ€™s virtual software environment, Red Bull ran audio and control data signals to three distant points, from the console to two parts of the pier 4,500 feet away. The efficiency of this transport protocol enabled them to know the precise amount of equipment needed to handle a project of any size, with far less technology than ever before.
â€œThe systems at Long Beach would have cost 10 times as much last year, in terms of hardware rentals and purchases,â€? said Risgin. â€œAVB is the ultimate convergence of AV and IT, so weâ€™re able to use the much-less-expensive IT types of components, like terminations and the BSS Audio/NETGEAR switches we used here, rather than the more costly equipment made specifically for pro audio applications. Weâ€™re leveraging the economies of scale of the IT industry.â€?
