You probably can't imagine how easy it is to define this term: PA system stands for Public Address system. That's all there is to it.
To explain the term a bit further, PA systems are the type of sound transmission systems that you can find, for example, in supermarkets, public pools, or sports grounds.
So, we are dealing with a system that is able to...
1. | ... cover long distances from the amp to the speakers. |
2. | ... provide a decentralised supply of sound to various spaces. |
3. | ... include microphone announcements. |
4. | ... transmit to various speakers (including speakers with differing output) until the amp's maximum output value (minus 10%) has been reached. |
