I got this unit off craigslist and I really don't need it since getting some other equipment. It has two optical inputs, two RCA analog inputs, two XLR inputs, one optical, two XLR, and two RCA outputs as well. One knob is missing and the other is kind of jammed in funny so it is kinda hard to turn it, but it works. I will include a mini disc I bought to test this unit so it is basically brand new. There seems to be some spots of surface rust on the bottom(see pictures) but it doesn't go through the case so it doesn't really affect anything. I'm looking for $75 (including paypal and shipping) OBO but remember shipping is going to be about $25 cuz this thing is kinda heavy and bulky.
