Located in the city of Metz and home to France’s top division football team, FC Metz, Stade Saint-Symphorien is the largest sports stadium in the region of Lorraine.
The stadium, which was originally constructed in 1923, was recently renovated to expand its seating sections and increase the overall capacity to 30,000.
To deliver highly intelligible speech for safety and in-game announcements as well as high-energy music playback during matches and other events, Stade Saint-Symphorien required a brand-new sound system with excellent sound quality and coverage for every seat.
French integrator Produc’son selected JBL Professional loudspeakers supplied by Freevox to replace the stadium’s aging audio system.
In order to meet international EN 54-24 voice alarm safety standards and ensure an effective experience, Produc’son hired Laurent Delenclos, technical director of Freevox, to design the stadium’s new audio system.
To deliver the clarity and balanced coverage required in all areas of the stadium, Delenclos selected a range of specialised JBL loudspeakers.
Produc’son hung distributed clusters of JBL AWS526-LS and AWS566-LS all weather speakers to provide the main sound reinforcement for the north, south, east and west seating sections, supplemented by ASB7128 subwoofers for additional low-frequency extension.
Delenclos’s design also included separate JBL AWS566-LS speaker arrays to ensure high-quality sound for players and official personnel on the playing field. To provide additional coverage for the corners of the stadium, Produc’son installed JBL PD595-LS and PD566-LS Precision Directivity loudspeakers.
In addition to the main arena sound system, Produc’son outfitted the concourse and locker room areas with JBL Control 25AV-LS and 14C-VA ceiling loudspeakers, augmented by custom EN 54-24 compliant enclosures designed by Produc’son.
“For stadium installations like this, it’s important that the entire system meets EN 54-24 specifications to guarantee fail-safe operation if important safety announcements need to be made,” said Delenclos.
“For example, if the stadium needs everybody to evacuate, we need to be certain that not only will the system reliably deliver messages to all areas of the facility, but also that these messages can be understood clearly.
