Public address systems are an essential tool in communication throughout a premises or campus. Public address systems can broadcast information from single or multiple sources to large groups of people in:
- Specific areas of a building – “zones”
- All areas of a building – “all call”
Messages are sent from an operator via a microphone console or telephone handset and are routed through amplifiers before being distributed from speakers in the designated areas.
PA Systems can distribute music into work places from digital media or radio.
