"The previous system was no longer adequate for the events held in the arena," explains Scott Bray, WJHW consultant. "The administration wanted sound reinforcement that was musical and would bring the game day experience up to fan's expectations. They also installed a new scoreboard during the upgrade for similar reasons."
One of the design goals was for the PA to fit above the new scoreboard, keeping sightlines clear. To this end, Bray specified six EAW line arrays - each made up of 12 KF740 modules - to hang in a circle above the centre court scoreboard. Scoreboard court-fill was delivered by 10 EAW MK5366i speakers. Two more arrays consisting of eight SB2001 subwoofers each, were hung tight to the ceiling and facing each other for low end support.
"We time-aligned the subwoofer steering to bring the overall lobe down into the bowl area," he adds. "Because we had a centre point of origination the sound was incredibly smooth with excellent low-end coverage - everyone was quite pleased with the end result."
With the lower seating area covered, Bray designed a distributed, zoned system made up of more EAW MK5366i loudspeakers. Each of the loudspeakers are assigned individual DSP and amplifier channels adding tremendous flexibility to the system design. Depending upon how the arena is being used, certain zones are turned on or off, or groups can be muted as needed.
"One of the major events held at the arena is the Walmart shareholders meeting," Bray continues. "The new system took their audio needs into account. It was designed so that they can easily tap into the upper balcony system as needed, which cuts down on load-in and adds to the overall sound quality of the event."
Justin Maland, U of A associate athletics director, was extremely pleased with the upgrade and the options it provides the University. "The University is looking toward the future and the possibility of hosting other large scale events for students," concludes Bray. "This system can support them for years to come."
