Given the unique very wide coverage challenge of the sanctuary, ASP Integrated Systems focused on QSC ISIS WideLine line array loudspeakers, which provide a coverage pattern of 140 degrees in the horizontal plane.
During an early stage of construction, a WideLine array was brought in and flown above the platform, allowing the sound team and key church personnel to evaluate both coverage and overall performance parameters. An interesting facet of the WideLine design is that while both 10-inch drivers handle low frequencies, only one handles mid frequencies, which enhances pattern control at the mid-high crossover.
“The biggest concern was absolutely even coverage throughout the entire room. Particularly with a space this wide, that’s tough to do,” explains Bob Blair of ASP. “In addition, the loudspeakers needed to be able to deliver even coverage throughout their defined pattern. The evaluation showed WideLine more than capable in both regards.”
Following the decision to go with WideLine main arrays, QSC provided design support, helping determine optimum array structure, placement and aiming. Three WideLine arrays, in left-center-right (LCR) configuration, are each made up of five loudspeakers flown in a gentle “J” configuration to provide vertical coverage to the back row of the main level. The arrays are spaced evenly in a row that corresponds with the very front edge of the platform.
