What is a public address system



PA system, public address system, paging system, personal amplification system - it can be confusing. But don't worry about the terminology, just concentrate on what it does! Explanation here :)

We encounter public address systems every day in many places, without even realising the fact. Every time we enter a department store or bank, when waiting for a train, we can hear music, advertising messages and information about train arrivals and departures played over various audio systems. 

Public address systems traditionally consist of input sources (e.g. microphones), amplifiers, control and monitoring equipment, and speakers - all linked by physical cabling. PA Systems are available today that simplify the cabling and equipment requirements of the public address system by running over the local area network (LAN).
