Public Address System

what it is?

public address system (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. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area.

how it work?

A public address (PA) system is for amplifying the human voice. In its simplest form, it has a microphone, mixer, and loudspeakers. It all starts with the microphone (mic), which converts sound pressure to voltage. That means when you speak or sing into the mic, its magnetic force outputs a small amount of voltage. That voltage is then sent to either a mixer or loudspeaker for amplification. Once boosted by a power amplifier, the voltage is so high that it forces the speakers to move and recreate the sound pressure changes which first entered the mic. The result is a much louder sounding voice.
