Columbia, MO | November, 2013 - The University of Missouri has a well-deserved reputation for going the extra mile for its student body, and their Student Recreation Center is a case in point. With a range of indoor and outdoor facilities to meet almost any discipline, their Mizzou Aquatic Center is just one of several jewels in the crown. The Aquatic Center's 50 meter pool and Diving Well have hosted numerous high-profile competitions, including Big 12 Swimming and Diving Championships, USA Swimming Series, and NCAA meets.
Since its opening in 2005, the Aquatic Center had also been known for its problematic acoustics. With its soaring glass and concrete walls, massive steel roof, and abundance of reflective surfaces, announcements were literally drowning in the din. That is, until the Center installed their new Iconyx digitally steered column array system.
"The original audio system never really provided the coverage they needed," explains Brian Noerlinger, with the Overland Park, Kansas offices of Conference Technologies, Inc. "The speakers were mounted at about 56 feet high, and the intelligibility factor was close to nil."
The ceiling's height created strategic challenges as well. "One of our biggest obstacles was taking the old speakers down," says Noerlinger. "The largest lift we could get into the building only went to 40 feet. Erecting a scaffold would have called for draining the pool, which wasn't an option. So I put a couple of pieces of conduit together with a couple of pulleys and a spring and a rope, and essentially made a big long tree trimmer. I threw a rope around the speakers, pried them off and reached up and cut. I had one heck of an audience watching from below."
As challenging as it was to get the old speakers down, installing anything else at that height would have proven impossible. "The original plan had been for the Iconyx to be part of the design, along with hanging additional speakers to replace the old ones," says Noerlinger. Instead, CTI worked with the Renkus-Heinz engineering team to design a system to cover the entire space using only three Iconyx columns.
The system is comprised of a single Iconyx IC Live ICL-FR-DUAL column in the center, flanked by IC Live ICL-FR columns on either side. "One of the ICL-FR columns covers the diving well area, with the ICL-FR-DUAL at dead center and the other ICL-FR down at the far end of the pool," says Noerlinger. "With just those three columns, we were able to achieve a consistent 110 dB coverage across the entire seating area." A CFX218S dual 18 inch subwoofer adds low end punch and power to pump up the crowd. Iconyx circuitry is specially treated to withstand the corrosive, high-chlorine environment - a process unique to Renkus-Heinz.
Intelligibility is also dramatically improved, Noerlinger adds. "Having the ability to control our point sources and direct the sound exactly where we wanted it — and more importantly, to steer it away from the places we didn't want it — made a tremendous difference. The sound in there now is crystal clear."
