Compact and Light and 22% smaller in volume than the DDJ-1000 and 1.3kg
On-Jog Display: This controller has the really nice on-jog displays that everyone has loved on the DDJ-1000, which can show playback time, BPM, and waveforms. It gives you a good sense of distance to Hot Cue / Loop Points, and also allows you to show full artwork for the playing track. Pretty awesome!
Feedback Reduction: This is a software-driven functionality that only the DDJ-800 supports so far, which is a feedback reduction function on the microphone inputs. It detects when your mics feed back and automatically cuts the volume.
Jog Adjust: Control your jog wheel resistance with these knobs for each deck, just like on CDJs.
Sound Color and Beat FX: The offerings here are pretty awesome – with four Sound Color FX and 14 beat FX. It’s a pretty great offering
Lots of additional Rekordbox DJ designed controls: there’s some really good shift layers on these controllers: Key Shift, Keyboard mode, “Super Fast Search”, Hot Cue Pages, Key Sync, Related Tracks, etc. If you’re not already a Rekordbox DJ power user, you’ll become one with one of these controllers simply by seeing the labels on this controller and discovering new functionality.
DDJ-400 now supports Algoriddim’s djay app !
