Electro-Voice EVA Line Arrays Selected For New Sanctuary At Trinity UMC In Texas

Reverberant environment called for loudspeakers with well-controlled dispersion

The new $10-million facilities of Trinity United Methodist Church of Arlington, TX is highlghted by a large yet elegantly simple wood-ceilinged sanctuary outfitted with a main system headed by Electro-Voice Expandable Vertical Array (EVA) line arrays.

The new sanctuary measures approximately 135 feet wide by 105 feet deep, with seating for 800 parishioners. However, it’s been designed by Scott Martsolf of Fort Worth architectural firm Martsolf Architecture to expand to 1,100 seats in the future.

Acoustical consulting for the new sanctuary was provided by Bill Johnson of Acoustic Design Associates, Dallas. And to design and install the sanctuary’s sound system, Martsolf brought in Electro Acoustics, a Fort Worth company with 30 years of experience in A/V design, engineering, installation and system support services.

Chris Jordan, account manager on the project for Electro Acoustics, notes that both the acoustics and the PA were shaped with the church’s worship style in mind. “The services are primarily traditional,” he says. “They have a custom pipe organ and an exceptional choir. To support that, the room is fairly live, with an RT-60 of 1.7 seconds.” The reverberation time puts the room at the short end of the target range typical of concert halls.

Jordan knew that the fairly reverberant environment called for loudspeakers with well-controlled dispersion, allowing sound energy to be directed toward the seating areas without also spilling onto the room’s hard-surfaced walls. “The EVA line arrays have exceptional pattern control, even at lower frequencies,” he says. “That allows us to provide clear speech to all of the seats in this live environment. Not only do the EVAs provide the clarity, musical quality and uniformity that we were looking for, they are also exceptionally easy to install and they require minimum equalization.

“Plus they’re a great value,” he continues. “There’s not a better-performing system for the money on the market. We’ve had great experience with EVA line arrays.”

The EVA-2082S full-range elements in the EVA line are available in four different coverage patterns, two of which are utilized at Trinity UMC. “We use the 906s for long throw and the 920s for short throw,” Jordan explains. The PA is configured as a left/right pair of arrays, each with two 906s above and three 920s below. The arrays are hung directly above the front lip of the stage, attached to exposed laminated beams using custom-designed rigging hardware.

“Being a traditional church,” he adds, “Trinity did not want or need subwoofers. The extended low frequency of the EVA arrays met all of their requirements for voice and acoustical performance. In fact, the church has received many compliments on the quality and clarity of the sound, so they are very happy with the performance of the system. They could not be more delighted, and they’ve already referred us for other projects.”
