PA system
A Public address or “PA” system is an electronic amplification system with a mixer, amplifier, and loudspeakers used to reinforce a given sound, e.g., a person making a speech, pre-recorded music, or message and distributing the sound throughout a venue. Include sports stadiums, public transportation vehicles, and facilities, and live or recorded music venues and events. Also may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution id required.
Simple PA Systems
Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with a larger number of speakers are widely used in institutional and commercial buildings, to read announcements or declare states of emergency.
