Outline at Rock in Rio 2026

Held over two weekends - September 4 to 7 and 11-13 September, at the Cidade do Rock in Rio de Janeiro's Parque Olimpico, the 2026 edition of Rock in Rio drew more than 700,000 people from 89 countries, according to the organizers. Foo Fighters, Elton John, Calvin Harris, Maroon 5, Avenged Sevenfold, Twenty One Pilots, and Stray Kids (the first K-pop act ever to headline the festival) topped a bill of 190 shows spread across eight stages.

For more than 15years, Outline has been part of the sound of Rock in Rio through Sao Paulo-based Gabisom Audio Equipment. In 2026, that footprint doubled: six of the festival's eight stages ran on Outline systems supplied by Gabisom, up from three in 2024.

Among them was the New Dance Order, the festival's electronic music stage, where on September 12 Brazilian DJ and producer Alok drew the largest crowd in the stage's history.

Across the six stages, Gabisom deployed several hundred Outline loudspeaker elements: GTO, GTO C-12, Superfly, Mantas 28 and DBS 18-2. Each stage had its own Outline Newton processors - the company's patented FPGA-based platform - with amplification from GTA Series units.

Rock in Rio 2026 will also be remembered for its weather: rainfall in the city over the first ten days of September exceeded the average for the whole month. "The rain was one of our artists this year," says Roberta Medina, vice-president of festival organiser Rock World, as the festival closed. The six Outline stages played on through both weekends, under the same skies.
