The KDC-C669 6-disc CD Changer provides the convenience of multi-CD play as well as excellent musical quality. It plays conventional CDs plus the CD-Rs and CD-RWs that you've recorded at home, and it's compatible with all Kenwood headunits with changer control. An Integrated Quad 1-Bit Digital-to-Analog Converter and an 8-Times Oversampling Digital Filter deliver highly accurate musical reproduction. And the KDC-C669 is virtually skip-proof: a Kenwood-designed anti-vibration disc transport keeps the music flowing smoothly even when the road gets rough. For convenience, it can be mounted at three different angles in your vehicle.
