USA - Cornerstone Church in Milwaukee, WI, a portable church that converts into a large banquet hall and wedding venue, has recently upgraded to a Martin Audio Wavefront Precision Mini line array system.
Wavefront Precision introduces a scalable approach to resolution and control of coverage that functions in tandem with external, dedicated multi-channel amplifiers in a uniquely flexible, upgradeable, and price-conscious system. The more cabinets with dedicated amplifier channels, the higher the resolution and scale of coverage control achievable.
System designer and integrator David Price says: “The hall is in a historic building and has several acoustic challenges which explains why we chose the WPM system. The room has a mammoth 35ft. tall x 30 ft. wide curved centre channel area where tons of acoustic energy can get trapped. WPM gives us control over directivity of the system so we can avoid that area and put the energy on the audience where it needs to be.”
Marble columns are spread throughout and the ceiling is all plaster with no acoustical panelling, and many cavities. “They also needed the system to be loud for the contemporary worship service without killing people in the first couple of rows, which happened with the previous PA because they had to push it so hard,” Price continued.
“With the Martin Audio WPM system, we could control the sound coverage from front to back and use the internal DSP to figure out the smoothness of coverage in terms of SPL they preferred. And now they’re incredibly happy with the system. Everybody gets the same quality of sound, from front row to back row and we’re avoiding most of the acoustic issues in the room.”
The actual setup includes four WPM enclosures a side, pole mounted on top of two SX118 subs on stage, all driven by a single iKON iK81 amplifier with two channels per box resolution. Four channels out of the 81 drive the mains and the remaining four channels drive the subs.
Asked about the WPM’s performance, David Price responds, “Obviously, it’s a night and day difference for the church in terms of audio quality. They’re much happier with the bass response, smoothness of the coverage and lack of resonance in the room. They’re not hearing the room as much, it’s much more controlled and precise. And they really appreciate the system’s portability, simplicity and ease of setup.”
