PA system (Public Address system)

A Public Address (PA) system is a set of equipment used to amplify sound so that messages or music can be heard clearly over a large area. It includes microphones to capture sound, amplifiers to increase the volume, and speakers to project the sound outward. PA systems are commonly used in schools, event venues, and public spaces to deliver announcements, speeches, or music to an audience, ensuring the speaker’s voice reaches everyone clearly and effectively.
