Portable intuitive 2-channel controller for Rekordbox DJ software with many popular user-friendly features that make it great choice even for the first-time DJs. The DDJ-RB is an update to last year's DDJ-SB2, and it ups the number of performance pads from four to eight, thanks to the dedicated Cue and Play buttons. Both controllers also come with the ''PC Master output'' feature in Rekordbox DJ, so you can assign the Master output to your laptop's speakers (for when you don't have an external pair of speakers connected to your DDJ-RB or DDJ-RR), and you can still monitor headphone cues on the DDJ-RB or DDJ-RR itself - a handy feature to have when you're on the go and need to practise. Sequence Call is also a new feature found on both controllers, which let you load a sequence you've stored directly from the pads themselves. Features include 4-deck control, Pad Trans beat effect, manual low/high pass filters on every channel, trim knobs and level meters, Filter Fade that can add 2 high pass filters to the crossfader, durable aluminium jog wheel (128 mm), 4 Hot Cues, and manual loop as well as auto loop. Controller is equipped with one 1/4 '' jack microphone input, one master (RCA) output and two headphone monitor outputs (1/4 '' jack, mini pin), and USB B port that also works as power supply. It is compatible with Windows (8.1, 8, 7 with Service Pack 1) and Mac OS X (10.10, 10.9, 10.8) and supports plug and play. - Dimensions: 482 x 272 x 58 mm - Weight: 2.1 kg - Colour: Black.
