Lisbon, Portugal (June 23, 2016)—When the recent five-day Rock in Rio Festival in Bela Park, Lisbon, it played daily to crowds of 70,000 or more. To cover the teeming masses, audio provider Gabisom Audio Equipment from Brazil fielded the largest Martin Audio MLA rig ever put together for a single stage.
Ultimately, the massive rig on the main World Stage sported 112 MLA, eight MLD, 60 MLX subs and 24 MLA Compact, through which audiences heard the likes of Bruce Springsteen and the E Street Band, Stereophonics, Queen and Adam Lambert, Mika, Fergie, Hollywood Vampires, Maroon 5, Avicii, and Charlie Puth.
Recalling a trademark aural and visual design element of Rock in Rio, hangs were doubled on either side of the stage with both flanking an array of subs. Typically the design calls for one array dedicated to vocals and the other instrumentation from the band.
Adding his experience was Martin Audio product support engineer, Chris Pyne, who said, "Geographically, this was a complicated place, as the contouring of the terrain was very different from left to right, climbing steeply on one side of the stage and running flat on the other. The challenge was to get even coverage and in order to compensate for this unusual geography, every single array required a different optimization. Fortunately, with MLA and Display 2 software this was a very easy problem to solve."
Many acts also used a full set of Martin Audio LE1500 and LE2100 monitors which were fed by the company's own MA5.2KDSP amplifiers.
