Public Address System
A public address system or PA system is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. Typical applications include sports fields, public transport and facilities, live or recorded music venues and events. A PA system may include multiple microphones or other sources, a mixer to combine and change multiple sources, and multiple amplifiers and speakers for higher volume or wider distribution.
