San Antonio, TX (June 19, 2013)—One of country music’s all-time greats, George Strait closed out the first half of his farewell tour on June 1 at San Antonio’s Alamodome in front of a record-breaking sold-out crowd of more than 73,000 fans.

Strait’s longtime live sound team includes FOH engineer George Olson and Dallas-based Onstage Systems, which supplied an L-Acoustics V-Dosc and Kudo package for most of this year’s tour stops. However, given the sheer size of the Alamodome concert in Strait’s hometown, the company chose to deploy its full inventory of K1 enclosures, which it augmented with additional cabinets from fellow Rental Network provider Clearwing Audio for an total of 120 K1 boxes.

According to Onstage Systems’ K1 audio tech Eric Thomas and systems tech Jason Chamlee, the concert’s eight flown arrays were evenly spaced in a ring above the perimeter of the circular rotating stage. A total of four hangs of 16 K1 with six Kara downfills addressed the longer north and south ends of the room, while the east and west sides were covered by four hangs of 14 K1 plus six Kara, each topped with two K1-SB filler enclosures to maintain visual continuity between all arrays.

To power and process the K1/Kara enclosures, Onstage positioned three LA-Rak touring racks—each containing three LA8 amplified controllers—on top of every array, minimizing the copper cable runs. Down on the floor level, four more LA-Rak were deployed to drive 16 dV-Dosc front-fills and 24 SB28 subs set up in an asymmetrical cardioid configuration around the stage.

“Even standing at the very back of the Alamodome’s nosebleed seats, the K1 arrays sounded like they were still right in our faces at more than 360 feet away,” says Thomas. “The indoor throw capability of the system is insanely impressive.”
