Career: Public Address System
A Public Address System (PA system) is an electronic sound amplification and distribution system with a microphone, amplifier, and loudspeakers. It is used to allow a person to address a large public, for example in schools, stadiums, transportation hubs, and public events. PA systems make it possible to broadcast announcements, music, or emergency information clearly across large areas. They can range from simple setups for small venues to complex systems used for large buildings or outdoor spaces.
