Sound Image Upgrades Audio System at Atlanta’s Tabernacle

Sound Image has improved the house PA system at the Tabernacle in Atlanta with an upgrade to Harman’s JBL VTX line arrays.

While the venue posed a variety of acoustic challenges, Sound Image’s application of the VTX system has created a listening experience on par with Atlanta’s modern venues.

The Tabernacle has a seating capacity of 2,600 people as well as an open, standing-room space on the ground level with three balconies at different levels.

For the main PA system, Richard Davis of Sound Image and his team installed 24 VTX V25 full-size line array elements (12 per side), with 12 S28 arrayable subwoofers (six per side), with left-right hangs of three Vertec VT4886 subcompact line array elements each for out fill.

Crown IT12000HD amplifiers power the system, which also features dbx DriveRack 4800 processing. Harman's HiQnet System Architect was employed for system configuration and monitoring.

The third floor of the Tabernacle also features a VIP lounge that features a main PA system of four VRX932LA Constant Curvature loudspeakers and two VRX918S subwoofers per side.

Davis said: “When I tuned the PA for the room, I didn’t even have
to touch the high end, It was pretty much right there from the

Billy Lindsey, FOH Engineer at the Tabernacle, said: “With the VTX system, you don’t have to struggle to get above the
resonance of the room. These boxes can also go really
low and easily go all the way out to 16K.”

In addition, Lindsey noted the advantages of the Crown IT12000HD
amplifiers, which feature the OmniDriveHD DSP engine (co-
developed with Harman’s BSS), specifically optimised for fast and efficient audio processing.

“What’s great is everything is in those amplifiers, they have the architecture in the amps all ready to go, which is amazing,” Lindsey

“We have four amp racks—two at house left and two at house right—and each one has a rack with eight
amps per side and four zones, with a secondary amp rack handling the front fills and subs.”
