DESC: D for design… F for fantastic… Z for Z-Enhancer… 675 is the secret code for this striking 2-DIN receiver… and MC stands for Music Catcher. The DFZ675MC is no ordinary source unit. Its sharp and striking front panel is illuminated by Clarion's 728-variable color LED. Its SD card slot and front panel AUX input makes it compatible with portable digital audio players. Its Music Catcher II technology gives you four-times high-speed recording ability. And it lets you select from four different equalization curves.
