Meridian, MS (June 4, 2004)–Wings Over Meridian 2004, a recent Naval air show held April 17-18 at Naval Air Station Meridian, benefitted from five Peavey power amps and a series of two-way, 12″ woofer-outfitted enclosures which backed the roaring Blue Angels and the U.S. Navy’s finest pilots.
The show, held mere minutes from Peavey International Headquarters, featured none of the metal or plastic horns and the distantly spaced loudspeaker clusters commonly associated with air shows. Also gone were racks upon racks of power amps. Armed with Peavey Impulse 1012 enclosures and GPS 3500 power amps, Peavey senior clinician and veteran live audio guru Marty McCann assembled a fully distributed audio system designed to cut through the din of jet engines from World War II-era planes to present-day bombers.
McCann placed the 31 total loudspeaker enclosures at 50-foot intervals along the crowd line with one power amp for every six speakers. “At air shows, you can always hear the system, but it may be too loud in certain spots, or it may be hard to understand because of a time lag between the clusters and fill speakers,” said Marty Papizan, civilian electrical engineer at Ground Electronics, NAS Meridian. “With the system Peavey came up with, no matter where you’re at, you won’t get more than a 22 millisecond delay in sound. That’s natural reverb.”
Running 31 loudspeakers in parallel along the 1600-foot perimeter caused a natural voltage drop, which McCann trumped with the powerful GPS 3500 amps and a series of line transformers. “We had to put 400 Watt transformers at each speaker to counter the drop in voltage, so every speaker sounded the same and put out the same volume,” said Papizan. Each of five GPS 3500 power amplifiers provided a 100 Volt distribution line to power six Impulse 1012 loudspeakers.
Captain Jeffrey Dickman, commanding officer at NAS Meridian, commented, “The Peavey sound system really made the Wings Over Meridian 2004 Air Show a spectacular event. The sound was so crisp and clear. I’ve been to many air shows and the sound system here was by far the best.”
