20 Most Recent Onkyo DX-C390 6-Disc CD Changer - Page 8 Questions & Answers

If it can recognize some discs then that cd may be faulty, or if it is unable to see any discs then that unit has a problem. You say its brand new, some machines have "transit screws" to remove but I did not see any mention in its instruction book. So its possible the mechanism or laser unit is faulty or damaged in some way for that I would refer back to where you bought it or the service company for Onkyo, as you will be at risk if you tried to fix it yourself as you will lose out on warranty.

On that model you cannot listen to channels A and B at the same time . If you do want to hook up both make sure you series wire them ....hook the positive "+" of speaker "A" to the amp "+", then connect the neg "-" of "A" to the "+" of speaker " B " and then the "-" of "B" to the "-" of the amp . This is because the amp only supports 6 to 16 ohm loads . Please search series vs parallel speaker wiring on Google and look at the image diagrams if you have any confusion about it
