I bought a new PA system last year, and when I did I realized that it is not only the amplifier and speakers that make up the main part of a really good PA system, but you also need to take time in choosing the microphone, because it is this that can really affect the sound quality. After talking to a salesman I decided to look at the range of TOA Microphones, because I had heard they give excellent sound quality. In the end I decided to buy one and I have been proved right because the sound quality really is excellent.
