Last night my brother and I and got out the mic for the first time. The mic picks up the voice fine but you can't hear the person who is singing though the speakers unless they scream into the mic, you still hear the normal vocal track in the song. Is there a way to adjust it so its more like karaoke? I know there is a mic volume toggle if you press the triangle but its turned all the way up by default. I'm wondering if I have a bad mic or something also.
