…when I receive images like this. Having attended the set ups for several major tours, I remain amazed at what goes into engineering, designing and installing the PA these events. And how quick and efficiently the men and women who rig these events get it done.

This one is beyond big.

These shots were taken at Atlanta’s Georgia Dome. The event was Passion 2013, and it took place during the first four days of the new year, drawing in more than 65,000 college-aged Christians from around the world.

Hosted by Passion City Church Founders Louie and Shelley Giglio, the event featured top Contemporary performers, including Chris Tomlin, David Crowder, Matt Redman, Kari Jobe, Lacrae, Jesus Culture and numerous other artists, alongside notable evangelical speakers like John Piper, Judah Smith, Francis Chan and Louie Giglio, himself.

To provide coverage and adequate (read: high) volume levels, Rat Sound Systems of Camarillo, CA was called in with a full L-ACOUSTICS system comprised of 108 K1, 96 V-DOSC, 36 KARA and 24 dV-DOSC elements, 40 SB28 sub enclosures, and 31 LA-RAK amplifier racks.

The main PA consisted of eight K1 arrays—six with 14 enclosures, and two with 12—flown above the circular stage area, each paired with either three or six KARA cabinets below for down-fill.

Three LA-RAKs were additionally positioned on the K-Bump rigging bar above each of the arrays to maximize floor space down below. For low-end reinforcement, 40 SB28 subwoofers were evenly distributed in groups of four around the outer ring of the stage and powered by 10 LA8.

On stage, LA8-powered 115XT HiQ wedges paired with SB18 subs served as monitors, while six tiny KIVA and ten larger dV-DOSC were deployed as front-fills on the outer and inner rings, respectively.

For delay, Rat Sound flew a ring of a dozen eight-box V-DOSC arrays powered by LA Series amplifiers to address the Dome’s upper seating areas.

“When we started re-loading the system back in, we knew we were up against the clock at all times,” Rat Crew Chief Ron Kimball notes.

“There were only 16 hours until the doors opened and all of the various departments—staging, rigging, lighting, video and so on—certainly had their work cut out for them. But knowing how easy the L-ACOUSTICS system would fly—especially with the flown amp racks, which eliminated long speaker cable runs—I told production that they would not be waiting on audio, and they didn’t!”

Later in the day, when the PA roared to life, the sound and coverage was just as Rat System Engineer Dan Bowers’ SOUNDVISION model had predicted and the rehearsal three weeks prior had confirmed.

“We had lots of kids coming up to front-of-house saying how great it sounded, and the Rat Sound tweet vine got loads of good comments,” recalls Andrew Gilchrist, Rat’s key PA tech.

Passion Conferences Production Manager Jonathan Sheehan added: “Prior to Passion 2013, we had been told by many people that what we were trying to do was simply impossible. There wouldn’t be enough time to set everything up, and if it somehow did get set up, it wouldn’t work well. Another one of the things that people said to us the whole time was that nothing ever sounds very good in the Dome because it’s just a big bowl and sound bounces all around in there. But during the very last session at the end of the conference, I was down front worshipping with some of our team and I had tears in my eyes because it just sounded so amazingly good. Despite all of the challenges and impossibilities, everything had come together just in time. It was such a miracle and so exciting to be a part of.”
