By PSW Staff • October 16, 2017 Martin Audio’s new Wavefront Precision Compact and Mini optimized arrays at First Pentecostal Church. The recent audio upgrade by Clark at the First Pentecostal Church in North Little Rock, Arkansas featured the world’s first installation of both Martin Audio’s new Wavefront Precision Compact and Mini optimized arrays with iKON amps along with CSX218 subs and the new LE100 monitors. As described by Clark project manager Brandon Byrd, “the Church had to replace an old, worn-out PA that didn’t cover the room or provide the audio quality and clarity they needed. Martin Audio had just come out with the new WPC system and it was a perfect choice for this installation because it offered great Martin Audio sonic performance and optimized coverage and control for the price. “The actual system includes 16 WPC a side for the main array with a side fill array of six WPM a side covering the extreme outside corners because they can really pack people into this place, especially for special events. The stage was modified to accommodate the five CSX218 subs per side that are recessed into the front with everything powered by the iKON amps. All the hangs are covered with white acoustical fabric to be more visually integrated.” First Pentecostal’s sanctuary is an acoustically challenging space with large domed ceilings, a balcony, stained glass windows and hard marble surfaces. “They didn’t want to add acoustical treatments,” says Byrd, “but with the WPC system you can get additional resolution and coverage by adding more boxes with a channel dedicated to a single amp. We went for the highest resolution which allowed the system to create interference that significantly reduces the audio level hitting the hard surfaces we wanted to avoid. That, plus the coverage is consistent throughout the space.” Asked about the system, First Pentecostal technical manager Nick McKinnon explains, “We were looking for speech intelligibility first and foremost. Conveying the message whether it was song or speech is our absolute priority. Keeping the vocals over the music and the preacher’s sermon clear and present in what is a very reverberant space is critically important for us. “So, the optimization capability of Martin Audio WPC was very attractive on paper and if it did what it said it was going to do that was the choice we had to make. Getting the sound off where it didn’t need to be and focused on the audience where it belonged was crucial for us, and it did exactly that. “I can tell you how we know it works. At our 35th annual Camp Meeting there were 4500 people in our 2800-seat sanctuary and a lot of crowd volume. In our balcony, the Hard Avoid area starts at the top of the mezzanine and there’s a walkway before the coverage starts at the seating area about six feet above the actual balcony rail. An usher who was in the walkway commented that it just didn’t sound that clear where he was standing. So, I asked him to walk up into the seating area of the balcony and he came back a few minutes to tell us the sound was perfect up there.” According to McKinnon, “the Church has two services on Sunday and one on Tuesday night with electric bands–we pretty much go full out for all three services. There’s a smaller chorale on Sunday mornings and a 100-voice choir on Sunday nights with more of a gospel feel. “When it comes to music reproduction, WPC is like sitting in front of a great set of studio monitors. We have a Midas Pro X console and we’ve gone from making 9dB changes in the EQ to 2 and 3 dB changes and really noticing the difference. The changes are very audible—we’re even hearing the compressors now if there’s too much reduction. “The coverage is truly exceptional. We have seating in alcoves and they were just getting reflected sound before. Now with the WPMs on the side, every seat in the house has even coverage, top to bottom, side to side. “We’ve also solved problems onstage with the new LE100 monitors. They combine compact, low-profile enclosures that give us expanded individual coverage for performers and speakers and they sound really good. “In terms of the subs, we brought the pastor in to hear some symphonic music and he mentioned that when you close your eyes, it’s more of an experience than just listening when you can hear the full spectrum of sound. And the overall reaction to the system has been overwhelmingly positive. The only thing the staff asked is why we didn’t do it sooner.” Martin Audio Clark Tagged with: Amplifiers Church Sound Installations Line Arrays Loudspeakers Martin Audio Stage Monitors Subwoofers Worship Audio · all topics Subscribe to Live Sound International Subscribe to Live Sound International magazine.
