As part of the $321m, two-year upgrade project, Dallas-based acoustical consultants Wrightson, Johnson, Haddon & Williams, Inc. (WJHW) was given the challenge to improve the audio clarity for the audience in the bowl and minimize noise concerns for the nearest residences that are only about 200 feet away. WJHW also had to make sure the new sound system would maintain the architectural integrity of the clean, classical lines.
For both architectural and environmental noise reasons, a point-source, scoreboard-mounted system was prohibitively problematic. "We concluded fairly early in the process that a distributed system was the best solution," recalls WJHW Principal Jack Wrightson. "Later we found out that Meyer Sound was developing the CAL loudspeaker, and it ended up being the right solution. It kept the historic look of the façade and by all accounts the university is very happy with the performance."
38 of the CAL 96 loudspeakers are spaced around most of the bowl rim (except for the press box section), with the slender enclosures blending harmoniously with surrounding flagpoles. The coherent, wide-bandwidth sound is precisely steered to cover the stands with minimal spill onto the field-and into referee microphones.
Two additional CAL 96 loudspeakers are mounted facing the student section to pump up the crowd. Stands below the new press box required a different solution, in this case relying on Meyer Sound MSL-4, UPM-1P, and UPJ-1P VariO loudspeakers. Coverage for the University Club, under-scoreboard and club level sections is supplied by MM-4 and MM-4XP self-powered loudspeakers, and additional UPM-1P loudspeakers. Galileo loudspeaker management systems with three Galileo 616 processors provide signal drive and alignment.
Including more than 200 Meyer Sound loudspeakers, the entire audio system was designed by John Kosco of WJHW under Jack Wrightson's direction. Installation was by Parsons Technologies of Minneapolis, Minn. with Jasyn Rousselow serving as lead sound integrator and Rich Norby as crew chief.
