I'll have pity..... Most mics DON'T have on/off switches. The ones that do are usually used for announcing bingo or raffle winners. To turn a mic on/off in most situations you mute the mic's channel on a mixer or something similar.
Are you sure it is even a mic you have and not a curling iron? Thats what I started singing with anyway, and man, I sounded hot enough to curl your hair!......okay my bad.
Hey, one dumb question earns one dumb answer right?
