Outline Audio powered one of the world’s great music festivals, Rock in Rio, which celebrated its 40th anniversary at this year’s event between 13-22 September, in Rio de Janeiro, Brazil.
Up to 1.4m fans attend Rock in Rio each year, making it one of the busiest music festivals in the world. Over the years, legends like Paul McCartney, Queen, Bruce Springsteen, AC/DC and Rod Stewart, have played it. Tjis year’s event attracted 730,000 fans across two weekends.
Outline’s audio systems have been deployed for the past 15 years for sound reinforcement, with São Paulo-based Gabisom Audio Equipment taking responsibility for the audio. This year, Outline’s GTO, GTO C-12, Superfly, and Mantas 28 models, driven by Outline power amplifiers, were deployed across three of the festival’s key stages: New Dance Order, Global Village, and Supernova.
The New Dance Order stage featured four PAs with 10 GTO boxes each, 48 DBS 18-2 sub-bass units, and 12 Mantas 28 units for front-fill, all supported by Newton processors for matrix management of two Yamaha consoles.
Danilo Costa, system engineer, Gabisom, said: “The first time I worked with the GTO and C-12 system, I was impressed by the headroom and clarity, particularly in the high frequencies, without harshness, and the strong, tight low-end response. This is ideal for high-energy concerts like EDM.”
Gabisom made significant investments in Outline audio technology in 2023 and 2024, following earlier purchases that included a substantial GTO C-12 system and Newton processors in 2020.
In 2020, Gabisom became the world’s largest owner of Newton inventory, utilising these FPGA-based processors for their signal management capabilities and WFIR filtering technology. Since that time, Newton devices have become a cornerstone of Gabisom’s operations, supporting both Outline and non-Outline systems at Rock in Rio.
