Atlanta HOW Gets L-Acoustics L-ISA System

Rather than an immersive audio application, Mount Paran Church’s new L-ISA System was installed to deal with speaker placement issues.

Atlanta, GA (June 15, 2020)—Atlanta’s Mount Paran Church has a massive 13,000-plus-member congregation, and a large sanctuary to match. Recently, technology solutions provider Diversified designed and installed a new audio system for the worship facility, sporting a new L-Acoustics loudspeaker system built upon L-ISA Hyperreal Sound technology. While that technology is often associated with immersive audio applications, that actually wasn’t what spurred the decision to implement it.

Tim Corder, strategic accounts director – House of Worship for Diversified, explained, “The previous loudspeaker system in Mount Paran’s main auditorium had been in place for many years, and as it aged, it began to have component failures that created erratic coverage—sonically ‘hot’ and ‘cold’ spots throughout the room—which was hampering the worship experience for many of their congregants.”

Although Diversified initially considered specifying a left/right array-based design for Mount Paran’s loudspeaker retrofit, the presence of large LED screens on either side of the stage meant that the array lengths necessary for providing optimal coverage would create sightline issues, particularly for those seated in the balcony.

“With so little space to work with above the screens, we chose to explore an L-ISA design, which offered us the ability to spread the system’s power out horizontally versus vertically,” says Nick Geiger, account executive and audio lead for Diversified. “This enabled us to achieve the SPL and coverage that we needed while keeping the speaker hangs compact enough to not cause visibility issues with the lighting and video facilities.”

Installed late last year, Mount Paran’s new loudspeaker complement is now composed of five arrays of four L-Acoustics A Series enclosures—two A15 Focus over two A15 Wide—evenly spread out and flown over the front of the stage as the Scene system and flanked by two arrays of one A15 Focus over two A15 Wide as the Extension system. Dual hangs of two A15 Wide deliver outfill coverage to the far left and right front seating areas, while two rear-firing A15 Wide positioned above the stage provide monitoring for the approximately 150 choir seats. Four KS28 subs, concealed by a scrim and centrally flown behind the Scene system, deliver low-end reinforcement throughout the entire auditorium.

Frontfill is achieved by six short-throw X8 enclosures deployed across the stage lip, with four compact 5XT systems located at center stage for sermon monitoring. Farther out in the house, two A15 and eight ARCS Focus systems serve as the delay ring around the catwalk covering the upper reaches of the balcony, while four locations of Kiva II provide underbalcony outfill. A combination of one LA12X and 13 LA4X amplified controllers power and process the entire loudspeaker system, while an L-ISA Controller and Processor combo facilitate the church’s new panoramic, object-based mixing approach.

Diversified also furnished Mount Paran’s FOH mix position with a new DiGiCo SD12 console, which is connected to L-ISA via Desk Link, natively bringing all source controls onto the desk surface and allowing engineers to access L‑ISA as an integrated element of their existing workflow.

Mount Paran Church technical director David Mendoza says that intelligibility was one of the key points his church was striving to improve with a new system, and L-Acoustics delivered on that, and more: “We wanted our entire congregation to be able to understand every single lyric being sung by the music team and every single word being spoken by the pastor,” he says. “When I heard L-ISA, I was blown away. It was a completely euphoric feeling.”
