What is Public Address System or PA System?
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipments. 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. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. PA systems play an extremely important role in relaying important announcements to patients, school staff and students, customers and office staff respectively.
How the PA System Works
PA systems use an Internet Protocol (IP) network instead of a central amplifier to distribute audio signals to different locations on the IP network, including the internet. Together, with an in-built intercom facility, a telephone serves as a microphone sending audio signals like messages and announcements to be received by the speakers.
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.
The main components of a Public Address System are
- Speakers – main speakers, subwoofers, and monitors
- Amplifiers – Needed only if using passive speakers
- Audio Mixer – Analog or Digital
- Speaker Processor
- Microphones – Dynamic or Condenser
- Effects – only used if needed
