Public Address Systems

A public address system (PA system) is an electronic sound amplification and distribution system with a microphone, amplifier and loudspeakers. They are tools for broadcasting public announcements and advertising messages, whether this involves live speech and recorded messages, playing atmospheric music, internet radio or other audio streams in a certain area with the option of playing various messages in different areas.
Simple PA systems are often used in small venues such as school’s auditoriums, churches, and restaurants.
Public Address  systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations for example, announcements of arrivals and departures at large and noisy airport and rail terminals, shopping centers, hotels, office buildings or sports and cultural facilities.
