The CDJ-800 is built around the company???s acclaimed Jog Wheel technology. In response to feedback from the pro-DJ community. The CDJ-800 includes legendary Pioneer functions such as Master Tempo and Cue/Loop Memory. Master Tempo locks the pitch of a track even when its speed is changed, allowing DJs to speed up or slow down the beat, without any difference to the vocals and instruments. Cue/Loop Memory allows a DJ to set a cue or loop point and then save it to the deck's internal memory. The CDJ-800 has enough capacity to save one cue point for up to 500 CDs, so that DJs can locate their favourite cue points instantly.
