Usually means Public Address system.
This can be a distributed supermarket or railway station announcement system, or a high power sound reinforcement system to amplify a music band.

PA = Public Address, or Pretty Awful (particularly railway stations)
VU = Volume Unit, or Virtually Useless
PPM = Peak Programme Meter, or Practically Perfect Meter

Default Yep, its one of those "confused" terms...

PA can mean,

Public Address, which implies generally low quality "piped" sound as in railway stations, hotels etc. Here you have many speakers and require a special "Public Address" amplifier. The speakers each have a transformer attached to them, and are actually fed a 110v "line" signal from the amplifier. The level of each speaker can be adjusted by using different taps on the transformers.
The amps are quite useful , because a good one will have "zones" on it which can be switched on or off etc

or

Professional Audio, as in live bands etc with mixing desks, big amps , microphones etc

That is the correct answer.

I fully agree with omnifex and Mr. Feedback.

But be aware there is a non-audio part of electronics where the use of P.A. for power amplifier is legitimate: RF
