EV EVA Powered by Dynacord C Series Amps: Upgrade for Grace Church by Starin
Located in suburban Akron, Ohio, Grace Church is a contemporary Christian church with eight locations. They sought a more musically coherent sound system to replace the aging point-source system in their main Bath Campus location. Integrator Kevin Root of Rootaudio saw the 620-seat sanctuary as an excellent candidate for a line-array system, and suggested Electro-Voice as a solution. “Electro-Voice systems deliver amazing sound quality without breaking the budget, so I spoke with my representative, CL Pugh,” says Root. “They set up demos of the X1 system and Expandable Vertical Array (EVA) for us. The larger-format, longer-throw X1 was more than this sanctuary – which seats just over 600 – needed, and the EVA filled the room perfectly. EVA has the right tone, covered

the space very evenly, and there was nothing abrasive or harsh. We knew right away that we had found the right system.”
EVA filled the room perfectly Working with EASE software, CL Pugh and Rootaudio designed a highly efficient system based around two five-box hangs of EVA-2082S dual-element array modules. The top three boxes have 90-by-6-degree dispersion, transitioning to the 120-by-20degree version beneath them for nearfield coverage. This layout provides full HF
coverage from about three feet off the stage, eliminating the need for front fills, side fills and delay speakers. The arrays are each paired with three EVA-1151D subwoofers, flown separately, directly behind each line array. As a final touch, three Electro-Voice ETX-18SP self-powered subwoofers are mounted beneath the front stage extension. The entire system is powered by just four Dynacord C3600FDi DSP power amplifiers. Each array requires just one amplifier, with one channel for the top three modules and the other feeding the bottom two boxes. Each flown set of three EVA1151D subs is powered by a single amplifier. “These are great amps,” says Root. “With the power they have, and the efficiency of
