Cates Audio story

July 15, 2016

With ever changing congregation needs, the New Life Assembly of God in Oak Grove, Missouri recently embarked on audio-visual upgrades to their 1,100-seat sanctuary.

Over the years, the church had tried a number of different solutions. As Cates Audio stepped in to evaluate the church’s needs, they came to the determination a line array solution was necessary. “A point-and-shoot just didn’t work in the facility layout,” explains Project Manager Brian Hance. “The church is so wide, it required us to use a left-center-right configuration. And with a balcony, we had to take into account the shading and splash that creates.” The system is comprised of three clusters each with four HDL20-A line array modules.

“The line array gave us the ability to cover all points. The pattern of the RCF cabinets let us slot sound into places that were not being reached with the previous system and provided a comfortable, evenly distributed sound.”

Choosing the RCF HDL20-A active dual 10” two-way line array module, “was an easy decision,” Hance says. In considering other solutions, “we found with many of the speaker cabinets we evaluated the horns were so harsh. The 2” high frequency driver of the RCF was very smooth and the box was very musical.”

Cates added two SUB8004-AS 18” subwoofers on the floor in front of the stage. “This was critical in our positioning so as not to create ‘power alleys’ that occur when subwoofers are set off to the sides of the room as is so often the case.”

The church offers their congregation three different service formats. A very traditional, low key service; a contemporary service; and rock-and-roll service. “With the RCF, it didn’t matter,” says Hance, “whether at 80 dB or 100 dB, the performance was the same.”

Once the church heard the speakers, they knew it allowed them to meet the variety of needs of each presentation.
