Brasilia National Stadium - Mané Garrincha

With the arrival of major sporting events in Brazil, such as the 2016 Olympics and the 2014 World Cup, we saw a unique opportunity to participate in a challenging and remarkable project: the sound system for the National Stadium in Brasília. This project allowed us to apply our expertise and cutting-edge technology to ensure excellent results and consolidate our position in the national market.

Initially opened in 1974 as the Governador Hélio Prates da Silveira Stadium, the stadium underwent extensive renovations between 2010 and 2013, when its capacity was increased from 45,200 to 71,400 people. During this period, its name was changed to the National Stadium of Brasília, but the tribute to Brazilian idol Mané Garrincha was restored after popular pressure, resulting in the current name: National Stadium of Brasília Mané Garrincha.

Our main goal for the project was to develop a sound system that not only met FIFA’s rigorous standards, but also provided an exceptional listening experience for the audience. To achieve this, we relied on Bose’s Modeler software, which enables detailed electroacoustic predictions. This feature was essential to accurately determine the installation locations for the RoomMatch speaker clusters, ensuring intelligibility and sound quality throughout the stadium.

We developed a three-dimensional model of the stadium to simulate the system’s performance in different areas, from the stands to the indoor rooms, boxes, bathrooms and circulation areas. This planning allowed us to ensure that the sound was clear and crisp, even in an environment with high acoustic complexity.

The implemented system is characterized by the diffusion of audio and video signals through the stadium's TCP/IP network and digital signal processing. We installed five technical rooms and eight technical racks on the roof, connected in a redundant data ring, to house equipment such as DSP processors and amplifiers. From these rooms, we distributed the amplified audio to the speakers located on walls, ceilings, roofs and stands, optimizing sound coverage.

The audio and video control room centralizes the equipment responsible for managing and processing signals, allowing integration with sources such as microphones, background music servers and announcement systems. This space is essential to ensure that operators can address specific messages to different areas of the stadium, automatically adjust volume levels to overcome crowd noise and prioritize emergency messages over the content being played.

The project was a milestone in our trajectory, not only due to its complexity and scale, but also due to the opportunity to raise the standard of Brazilian acoustic installations and demonstrate our potential. With this experience, we reaffirm our commitment to delivering innovative and high-quality solutions for large sports arenas.
