Arrange Speakers

hi
I don't know this is correct place for this question or not.
Anyway i want know about arrange band speaker .i want know this science not in experience.
I just know this science called PA System.
Please help me
Thanx.
 

It's mostly art (or in other words: experience) rather than science.
 
A PA system uses an amplifier that has a 70V output voltage at its rated output power. Each PA speaker has a tapped transformer and its power is set by which tap its transformer is set to.
The total power of all the speakers must not exceed the amplifier's max power output rating.
 
A PA system uses an amplifier that has a 70V output voltage.

The technique started after world war II, it's still used for distributed speakers in public buildings and possibly province
sport arenas. Europe has mostly used 100V RMS, by the way. The term PA is also used for stage sound systems, that use a
distinct different technique. Basically, each speaker has it's own amplifier now.
 
I remember the old 100V system but agree the term is more likely to but used for general sound distribution, more for music now than 'Public Address' which was more for speech or 'addressing the public'.

PA system = Public Address system = microphone--Amplifier--Speakers.
