Bitten by the bug of karaoke and have having two nices who love it I am thinking about purchasing some karaoke DVD's. I dont believe the DAVS 550 has a microphone in but I have read some where I may be able to use a microphose mixer with a DVD player. I am asuming this is if you have a seperate amp and dvd player but I am hoping there will be some way of doing this. If anyone has any experience of advice on this setup I would appreciate it. Thanks.
