The Word Of Faith Love Center, located in Atlanta, recently installed a new sound reinforcement system featuring RCF HDL line arrays.
The church leaders called upon Atlanta Audio Visual to design and install the new system.
"Their goal was a system that would cover every seat in the house while providing vocal intelligibility and enough volume to satisfy their contemporary praise band," explains Brad McWhorter, CEO of Atlanta Audio Visual. "The sanctuary is a long rectangular room with a back balcony and 30 foot ceilings. I immediately thought of the RCF HDL line array system."
A long-time RCF fan, McWhorter designed a powered left-right system with each array consisting of one HDL 18-AS sub followed by six HDL 20A line array modules.
The HDL 20-A features two 10-inch woofers and one 3-inch titanium compression driver, a 1400 Watt peak power two-way digital amplifier with switch mode power supply and DSP controlled input section. With a maximum delivery of 135 dB SPL, it would more than cover the church's requirements.
The HDL 18-AS is a flyable high power subwoofer designed to integrate in the HDL 20-A system. The bass reflex design guarantees a deep, linear power response while the 4-inch voice coil vented design woofer provides minimum power compression. The end result is the driving low end the music portion of the services demanded.
"We were originally called in for vocal intelligibility issues," adds McWhorter. "Their existing system wasn't meeting the needs of today's high energy, low bass driving, music oriented services. RCF fit the bill perfectly."
Not only did the line arrays meet the criteria of the growing church, but they also were lightweight enough to meet the installation requirements as well.
"The most logical location to hang the arrays were from beams that were constructed of laminated wood back in 1979," McWhorter explains. "It was going to be a challenge to hang 800 pounds from them. Size and weight were definitely a factor in the design process."
Because the beams would have to serve as the structural base to hang the arrays, Sykes Consulting was brought in to ensure the system was hung from a structurally sound location.
"Sykes designed a one-half inch thick steel U bracket to slip over the beam that could support 445 lbs per anchor," says McWhorter. "With two anchors per array, it was more than sufficient for the HDL arrays."
To further counter acoustic challenges, the team installed Auralex acoustical panels across the columns and the balcony face to quiet the room by an additional 10 dB.
"The church is extremely happy with the end results," concludes McWorter. "The 6-piece band, choir and vocalists sound outstanding and the members can still hear the spoken word clearly. It was the ideal solution all around."
