Is anyone using there systems for karaoke? I'm curius cause i can't seem to use karaoke without getting a lot of distortion. I have a LD player by pioneer and another cd bassed played and they both distort easily. I'm using a marantz 6300 hooked up to a 140X3 amp. my speakers are supposed to put out 150 watts rms. Is it supposed to do this? What i mean by distort is when someone is singing and then when you raise your voice on songs it starts to break up and the signal overload lights up on the marantz. anyone else have this problem?
