[ATTACH=CONFIG]199476.vB5-legacyid=10962[/ATTACH]Clay City, IN (October 2014) – When the Clay City Eels light up the high school gymnasium, they are doing it with the help of a new sound reinforcement system featuring One Systems, Inc. loudspeakers.
The gymnasium at the Clay City Junior/Senior High School, located in Clay City, Indiana, recently replaced an outdated audio system with a new distributed system built around nine OPALine loudspeakers from One Systems’ On Point Audio brand.
Tech Electronics Indiana, with headquarters in St. Louis, MO, was brought in to design and install a new system for the multi-purpose facility.
The gymnasium features a sunken basketball floor with tiered bleacher seating for 2,000 around three sides`of the court. A stage used for graduation and other school functions is recessed back from the fourth wall.
“As with most gymnasiums, the room has a lot of hard surfaces, eliminating bounce-back from the walls and ceilings was key to the system design,” explains Jeff Watson, director of Tech Electronics of Indiana. “They wanted clarity but also needed it to be loud enough for announcers to be heard over the noise levels in the gym during basketball games.”
Tech Electronics designed a targeted distributed system – a total of six OPALine vertical line array loudspeakers covered the home and visitor bleachers (three for each side), two more cover the seating at the end of the court while another is positioned above the stage to cover the gym floor.
“We specified the OPALine loudspeakers because we wanted to be able to steer the sound where we needed it,” adds Watson. “We have used One Systems products in the past but this was our first experience with OPALine. They worked exactly as advertised and provide the clarity and volume the application needs.”
OPALine is a single-box vertical line array loudspeaker that generates very wide horizontal dispersion, while providing precise vertical pattern control. The defined vertical pattern offers excellent intelligibility in reverberant spaces similar to the gymnasium, and maximizes direct to reflected ratios of acoustic radiation.
Each enclosure is loaded with four NP8 high-output, narrow-profile woofers that provide the same cone acoustical radiating area as conventional 8-inch (203mm) woofers, but in a smaller size. Each NP8 operates up to 1,000 Hz and is configured to deliver excellent vertical pattern control up to its crossover frequency.
The HF section of the OPALine features two vertical line array waveguides that are both coupled to very high-output, medium-format titanium compression drivers. Both high-frequency waveguides operate between 1,000 Hz and 2,000 Hz in parallel mode. Above 2,000Hz, the lower waveguide is gradually attenuated to maintain the desired vertical beamwidth of the OPALine system. This configuration ensures excellent vocal range pattern control, superior system intelligibility, and high reliability.
The system is powered by three Crown CTS 2000 amplifiers, also provided by Tech Electronics of Indiana.
“The school is very pleased with the end result,” concludes Watson. “It’s the best the gym has sounded in quite some time.”
