This is a Denon DCM-270 5-Disc CD Changer which is in great physical condition but is being sold for parts or repair.  As you can see in video, the CD tray moves back and forth or just goes around and does not stop whether it is open or closed.  The Photo Transistor which detects tray likely needs replaced.  Prior to that, unit worked great and sounded wonderful.  Please see both user manual and service manual links below.  The part information for the Photo Transister PCB can be found on page 11 of service manual.

If it does not sell, I will likely repair at some point soon so if you wish to snag a deal on this to repair yourself or use for parts, grab it now.

The unit is 8.3 inches tall, 19.1 inches wide, and 20.3 inches long, weighing 17 pounds.

THe unit has advance multilevel Noise Shaping DAC, Live Disc Exchange, 16-Track Music Calendar, Variable Headphone and Line Outputs, Program Plam for up to 32 tracks, Random Play, Repeat Play, and Direct Selection.
