Digital PA for smart city sports stadium with crowd management and emergency protocols?
Industry: smart city | Architecture: DIGITAL
A 50,000-capacity sports stadium demands a PA system engineered for crowd safety and spectator experience simultaneously. The BNA 8000 PA central exchange manages discrete zones — North stand, South stand, VIP enclosure, concourse, parking. BNA 7301 outdoor horn speakers mounted on the stadium fascia and roof structure deliver high-SPL audio above crowd noise. BNA 7302 indoor cone speakers in concourse areas and concession stands provide clear, lower-volume operational audio. BNA 8200 field call stations at each stand entry, medical post, and security cabin allow instant field communication with the central control room. BNA 8100 master station at the stadium control room handles match announcements, emergency evacuation, and security alerts. BNA 500W amplifiers are deployed in multiple stacks to achieve the required SPL across the full stadium. Crowd evacuation protocols trigger priority override across all zones.
