Community Professional R-Series Loudspeakers Deployed At Three World Cup 2014 Stadiums

Chosen for all-weather reliability, well-defined coverage, and high intelligibility.

Community Professional R-Series loudspeakers are being utilized at three stadiums hosting matches for the upcoming FIFA World Cup soccer (football) tournament in Brazil.

Estádio Mineirão, a 62,160-seat stadium in the Brazilian city of Belo Horizonte, underwent an extensive renovation over the past couple of years that includes a new sound reinforcement system. Soundvision Engineering, the largest professional audio and video contract integrator in Brazil, was commissioned by contract holder Emílio Miranda of Johnson Controls Brazil to design and install the system.

Soundvision CEO Antonio Tadeu Torquato and new business manager Leandro Freire carried out an extensive evaluation of loudspeakers, choosing Community R2 full-range loudspeakers designed for large outdoor applications such as stadiums, basing their choice on all-weather reliability, well-defined coverage, and high intelligibility.

Specifically, the main system incorporates 24 loudspeakers clusters, each with four or five R2s. In total, the project includes 24 model R2-52, 24 R2-694, 6 R2-94, 4 R2-77 and 48 R2-474. They’re fed by amplifiers and processors in five technical rooms that are networked with CobraNet with D-link redundancy and BSS-BLU processors. The system is also connected to the stadium’s fire alarm system, enabling the distribution of live and pre-recorded messages for mass notification or emergency evacuation.

After installation, performance analysis measurements made by Soundvision systems manager Fernando Gargantini and Community technical director Dave Howden showed that the system performance met the project specification and provided the desired coverage.

Soundvision was also chosen to provide systems for two more World Cup stadiums, Arena de Sao Paulo and Arena Amazonia, and both were also fitted with Community R-Series.

Arena de Sao Paulo (in Carmosina, Sao Paulo) has been built specifically for the 2014 World Cup, offering a seating capacity of 65,000 for the event. This system incorporates 16 Community R2-94, 16 R2-694’s and 16 R2-77. Meanwhile, Arena Amazonia, located in the city of Manaus in the Amazon rainforest, seats 42,377 spectators, with the system utilizing 64 Community R2-474 and 76 R.25-94T.
