Since its inauguration in 1933, the Bollaert-Delelis stadium, located in Lens, looks back on a rich sport history. With an initial capacity of 12,000 seats, the stadium has evolved over the decades to now accommodate nearly 38,000 visitors, making it one of the most emblematic stadiums in France. It has witnessed historic moments in French football and hosted numerous international matches, reflecting its importance in the national sporting landscape. The stadium has also undergone several renovations, the most recent aimed at modernizing its facilities and improving the fan experience while meeting the highest standards of safety and comfort.

As part of this modernization, a specific technical installation was carried out to improve the sound system, with focus on acoustic performance and compliance with safety standards. The installation is based on an infrastructure made up of 6 bays of 36 units, equipped to effectively meet the requirements of a stadium of this size.

Key elements:

• 1 SX-2000SM system manager for centralized supervision,

• 2 SX-2100AI audio matrices and 5 SX-2100AO matrices dedicated to the management of incoming and outgoing signals,

• Amplifiers specifically selected for their performance, including 3 VP-3154, 5 VP-3304, 1 VP-3504, 1 VP-2064, and 1 VP-2122,

• The sound installation uses a wide range of loudspeakers, including CS-154BS and CS-64BS for general broadcast, BS-1015BSB and F-1300BTWP EB-Q loudspeakers for exterior areas, as well as PC-2369EN and SC-630M EBQ for homogeneous coverage of the stadium.

• 20 Nexo clusters, integrating 96 Géo S-12 speakers, were installed to offer exceptional sound quality, suitable for large crowds and major sporting events.
