More Groundbreaking Coverage from Martin Audio MLA for Zac Brown Band in Miami

Held at Lummus Park on South Beach before the NASCAR race in Homestead, Florida, a free-for-the-fans concert starred the Zac Brown Band with special guest Nic Cowan.

Special Event Services handled sound and staging, continuing to make heavy use of its new Martin Audio MLA (Multicellular Loudspeaker Array) system.

The crew, which consisted of Eric Roderick (front-of-house/production manager), Preston Soper (system tech), Frank Sadler (Pro Tools/stage tech) and Jake Bartol (monitor tech), rigged 12 MLA enclosures per side with 12 MLX sub bass enclosures in a center configuration and four Martin W8LMs for near fills.

Martin Audio's MLA system was formally introduced to U.S. audiences during a Zac Brown Band tour earlier in the year. Roderick thought "the system sounded incredible" while Soper called it "the most sonically pleasing system I've ever heard."

Asked how they determined the setup given the winds coming off the beach in South Beach, Soper said, "Martin's Display 2 optimization process gives you a linear response, so it's not a different EQ at different regions but the same EQ everywhere, allowing Eric to put his contour preferences or house-curve on it.

"During the course of the show, Global EQ, a shelving filter in 0.5dB increments, was applied to compensate for changing atmospheric conditions. One atmospheric condition that one would expect in a location like a beach with rapidly changing wind gusts, didn't affect the coherency of the mix.

"In South Beach, we achieved the overall SPL target of 4.5db (+1.5dB at audience start, 0dB at mix and -3dB at audience rear) and an overall ripple variation of +/- 0.5dB throughout this region. The coverage area of the MLA was to 80m where the delay speakers took over for the next 80m."

Continuing, Soper explains, "the width of the coverage area was only 40m and one thing that always stands out about the MLA is the wider stereo image. It's typical to hear the left side even when you are off axis to the right side of right. The wider stereo image allowed Eric to spread his inputs in the mix without fear of people missing things from one side of the venue to the other or have them get lost in the mix.

"The control of leakage on the stage and roof greatly reduced the effect of the acoustical crossover on the mix for everybody who came to see the show regardless of where they ended up on the beach that night. Everyone got a sonically pleasing show."

John Saviano, of Quest Marketing, who has worked closely with SES owner Jim Brammer added, "The Martin MLA rig is one superior speaker system. It does exactly what it promises: coverage, SPL, tonality, everything. It really is consistent, front to back, side-to-side, etc. Quite amazing."
