public address systems

A public address (PA) system is a setup that allows speakers, microphones, amplifiers, and speakers to broadcast sound to a large audience. It’s used in places like schools, stadiums, and auditoriums to make announcements, give speeches, or play music. The microphone captures a person’s voice and sends it to the amplifier, which boosts the sound. The amplified sound then travels through speakers, making it loud enough for everyone to hear clearly. This system ensures important messages are communicated effectively over a wide area.
