Pennsylvania high school upgrades auditorium with Electro‑Voice

December 9, 2008

A new Electro-Voice XLD sound system has brought a new lease on life to the auditorium at Trinity High School in Washington, Pa.

The system was designed by Accent Electronic Systems Integrators (Bridgeville, Pa.), working with electrical consultants A1 Electrical and Hornfeck Engineering of Pittsburgh, Pa.

“the XLD provides intelligible, high‑quality sound to the very back of the hall.”

Trinity’s principal, Donald Snoke, used one word to describe the sound: “Phenomenal!“

The new system at Trinity comprises eight XLD281 full-range line array loudspeakers, three XS212 subwoofer cabinets (flown behind the XLD array), two TG7 amplifiers, and one TG5 amplifier with UCC1 USB-CAN converters and RCM-26 remote control modules. The amplifiers are controlled and monitored via IRIS-Net software (via a touch panel). The system is the auditorium’s first line array, and with the pattern control the XLD delivers, Dave Baret of Accent ESI cannot imagine using any other product for an application like this. Baret comments:

“Because of the length and height of the auditorium, we agreed that a line array would perform most effectively in the space. We decided to use EV XLD boxes because they have the best pattern control across a wide frequency range.“

EV XLD281 loudspeakers employ Coverage Control Technology (CCT™) to provide horizontal coverage to 250 Hz, ideal for spaces like Trinity’s stage and auditorium where precise control is necessary for a perfect sound, especially throughout the vocal range. “Trinity usually fills its auditorium for every event,“ Baret adds, “and the XLD provides intelligible, high-quality sound to the very back of the hall. They often have 16 wireless microphones active on stage at any given time, and the XLD’s precise coverage and frequency control helps keep feedback and reflection to a minimum, while giving us all the gain and headroom we need for superb audio on every seat. The response to the sound has been extremely positive.“

“This was a considerable investment for the school,“ Baret continues; “they aren’t going to change their system again for a long time, so they wanted a high-end system to address all their needs, from musicals and vocal productions to lectures and presentations. The XLD gives them that versatility, with concert-quality finesse and power handling, and warm intelligibility for spoken word applications. And because their auditorium is one of the bigger venues in the area, Trinity wants to use their space for the community, whether for a movie night, or concerts, or anything else. With the flexibility they get from the XLD281s, they can do that.“
