PA System vs Commercial Audio System: Hong Kong Comparison & Cost Guide

FAQ
Can a commercial property install only a commercial audio system without a PA system?
No. Under Hong Kong fire safety regulations, designated commercial properties must install compliant PA broadcast systems for emergency evacuation announcements. Commercial audio is supplementary and cannot replace the statutory PA system. The two can share some speakers but control systems must remain independent.
How much do PA and commercial audio systems differ in cost?
PA broadcast systems (fire-compliant) cost HK$30,000–80,000 per floor, with a whole building at HK$200,000–500,000. Commercial audio systems vary by venue size and quality — small restaurants at HK$15,000–40,000, large retail spaces at HK$50,000–150,000.
