How do I make a simple, portable P.A. system using a boom box and a microphone?
I have a boom box with dual cassette, AM/FM radio and line-in input. It also has a microphone input. I have tried plugging a mic in but it seems to work only when I have a cassette in it and it is on record. What do I need to do or to add to make a simple public address system without running the cassette record?
