Outline audio systems powered Perry’s Stage at the recent Lollapalooza festival, one of South America’s premier music events, in São Paulo, Brazil. Local audio hire company Gabisom Audio Equipment deployed Outline’s GTO and GTO C-12 line-array systems for the stage, which is known for electronic music and sets from famous DJs.
Lollapalooza began in 1991 in Chicago, but has since expanded across four continents. The 2025 Brazilian edition, held from March 28-30 in São Paulo, was headlined by superstars Olivia Rodrigo, Rüfüs Du Sol, Shawn Mendes, Alanis Morissette, Justin Timberlake and Tool.
Danilo Costa, one of Gabisom’s sound system engineers, explained: “It’s the second year of the Outline GTO and GTO C-12 at Lollapalooza’s Perry’s Stage. This time, I’ve got 9 GTOs and 9 GTO C-12s on each hang (LL + L + R + RR), plus an LLL with 12 Superfly boxes. We also had 44 Outline DBS 18-2 subs and 8 Mantas 28 for front fills.
“The sound was incredible. The subs’ configuration is an end-fire setup with digital arc delay, covering 120m in width and 170m in depth. As always, our Newtons made managing the complex setup effortless, ensuring precise control throughout.”
He added: “Once again, the GTO proved its unmatched capability, effortlessly delivering every sonic detail with absolute precision. It’s like having a high-end studio monitor on a massive scale – every nuance is there, uncoloured and intact, but with the sheer power and headroom needed for a festival of this magnitude. Working with this system is both exciting and reassuring because you know it will perform flawlessly every time.”
Newton, Outline’s FPGA-based processing platform, managed the complex set-up.
Lollapalooza now brings diverse lineups to audiences in Argentina, Brazil, Germany, France, Sweden, Israel, and India. Its South American journey began in 2011.
