Port Perry, Ontario (March 26, 2014)—Akron-based The Chapel recently renovated the sanctuary on its Green Campus in Green, OH, updating to an Adamson SpekTrix sound reinforcement system.
The worship services vary, including live praise bands, piano, or choir, and on occasion the sanctuary is also used for concerts, which have a different set of requirements as well. The church leaders called in Pro Audio Innovations, located in nearby Canton, Ohio, to assist with the design and installation.
“The sanctuary is a clamshell shaped room with a balcony and ramped seating on the sides,” explains Dan Giarrana, owner of Pro Audio Innovations. “The room seats around 1,700 and the services are very well attended. They wanted a new system that would cover the room evenly and also be aesthetically attractive.”
The main PA consists of eight SpekTrix enclosures flown left and right, run in stereo. A center cluster of two SpekTrix subwoofers are flown in a cardioid pattern, making a complete in line 4-way system. A pair of T21 subwoofers located on the ground crossed below the SpekTrix subs receive an analog signal sent on an aux, creating essentially a 5-way system.
The side, ramped seating and balcony fill is provided by nine Adamson Point Concentric PC12 loudspeakers run passive and inline with the main AES L/R feed.
“In order to hang the arrays to optimally cover the room, they needed to be at a certain height,” explains Giarrana. “Once we explored the ceiling, we realized that a) we were going to have to build a structure that could handle the weight of the arrays and b) it would have to hang down 11 feet in between heat ducts already in the ceiling, so there was little room to work with.”
Giarrana and his team built a structure that could hold the 2,000 pounds and also included motors that could raise and lower the arrays for maintenance if needed. All of the chain, wires and cable lines were hidden in 4-inch conduit painted to match the line arrays.
Pro Audio Innovations provided Lab.gruppen PLM amplifiers to power the system. Two Yamaha M7CL consoles are located at front-of-house to handle both FOH and monitor duties. An Apogee Big Ben and ProCo Momentum digital snakes tie the system together.
