I am having a party in a few weeks and wanted a karaoke. I am just wondering is there anyway that I can plug in a microphone into my Sony 830. I was thinking of using the 5.1 channel inputs, but leaving out the centre as the microphone channel. The pioneer 626dvd can decode the other channels if need be (i can say theres no centre hooked up). I got a connection today to hook up a mic of a computer to it but no luck. I plugged it into the centre input. Is there any other cheap way of doing this?
