Rapid City, SD-based Haggerty's Audio Video designed and installed the systems, both centred around Community Professional R-Series loudspeakers. As Haggerty's Steve Foudray explains, the facilities had been sorely in need of audio improvements.
"The stadium had several issues, each reinforcing the other," he says. "The system itself was underpowered - just a few old horns and a single 100 Watt amp - so it was low fidelity and distorted to begin with. The horns were also mounted on the scoreboards at one end of the field, so there was a time delay between the announcer and the horns. And the horns were directly across from the large gymnasium building, so there was an echo problem as well."
Dale Grant, Chadron State's vice president for administration, confirms that the old systems left the college wanting. "I don't think anyone who has been to a football game at Elliott Field would argue that we needed to do something different there," he said.
The Haggerty's team of Foudray, Mike Moore and Dan Haggerty replaced the 40-year-old horns with four Community R.5 full-range two-way loudspeakers covering the bleacher seating, and a pair of R1-94 long-throw systems for the end zones. "We created a vertical array with four R.5 subwoofers and an R.5HP on a custom bracket," says Foudray. "It keeps the SPL of the bleachers under control, and fills the entire field." The systems are powered by Electrovoice CPS Series amplifiers, with Rane DSP providing system processing.
