Public Address Systems

A public address (PA) system is a form of audio system used to amplify sound in public spaces such as schools, stadiums, airports, train stations, and shopping malls. The primary function of a public address system is to provide audible and intelligible communication to a large audience for either emergency or informational purposes. In addition to a microphone, an amplifier, and loudspeakers, public address systems may also include mixers, equalisers, compressors, and processors.

A typical public address system functions by capturing sound waves from a microphone or other input source, converting them into electrical signals, amplifying the signals, and then reproducing them via one or more loudspeakers. The sound waves are evenly dispersed throughout the room, allowing people to hear them distinctly and undistorted.
