Overview – Public address systems

(PA) Public Address systems are communication devices with mixer, amplifier and loudspeakers used to transmit messages around a building or large open space. Simple PA systems can be used in large work areas where employees are undertaking manual work.

PA systems with a number of speakers are widely used in institutional and commercial buildings. For employee events in large stadiums or football arenas, PA systems provide another way to convey your messages. PA communications can take the form of an announcement, important update or even a mini-newscast.

Tone BulbHelpful tip:


Sometimes Public Address systems have to compete with a lot of other noise and activity to gain employees’ attention. For this reason, it’s important that messages relayed over PAs are:
Accurate, Brief, Clear, Easily heard and understood, Memorable, Suit the purpose, audience and occasion. Give a clear ‘call to action’, if required.
