The new DDJ-SB sports two large Pioneer jogwheels, 16 performance pads, and basic FX, tempo and mixer controls.
From a size perspective, the unit is significantly lighter (2.1 kg, its about half the weight of the DDJ-SR) and smaller in dimensions than the other controllers in the DDJ-S line. Here is the full hardware featureset:
USB powered
Combo HP/LP filter for each channel.
Hot Cue, Auto Loop, Manual Loop and Sampler modes
Dedicated Serato software FX Control
Single Mic Input (1/4" jack)
Master RCA output
Both 1/4 and 1/8 mini jack headphone outs
High resolution, touch sensitive jog wheels
There is only one new feature on the DDJ-SB that we haven't seen on any other Pioneer unit before, called Filter Fade - similar to the Fader FX of DJTTs VCI-100 mappings long ago. Pioneer details the Filter Fade feature:
For extremely smooth blending transitions when using the cross-fader, a new Filter Fade function can be turned on (via a button in the center of the mixer) even with music that has vastly different styles. The high-pass filter of the left and right decks is linked with the actions of the cross-fader, and the deck volume output automatically adjusts while applying the bass filter, resulting in natural sounding mix effect.
