Facts about PA Speakers
A pa system in its full terminology is an electronic amplification system that consists of a mixer, amplifier and loud PA speakers that are used to feed the voice through a pa system to make it louder so many people can hear the sound produced, more often than not this is music.
A PA system is basically a clearer version of a loud hailer or mega phone which can be used to publically address people, hence the abbreviated version Public Address system. A pa system can also be used to address large crowds of people in the open air, in meeting rooms, in churches and other large gatherings but where they really come into their own is for live performances through the use of PA Speakers.
Live performances by bands, duets, trio’s and solo artists are ideally suited to PA Speakers 
which allows them to broadcast to a lot of people without having to raise the singing so you get the richness of their voice but with the added clarity of the PA Speaker making the voice louder.
A simple PA sound system is ideally suited to small venues such as churches, meeting rooms and small bars. Adding extra pa speakers will then intensify the sound making it a much louder sound over all.
