The Roland DJ-202 is a forward-thinking Serato DJ controller that offers DJs the features and layout of a full-size professional controller in a rugged and portable unit. Every DJ-202 purchased in the U.S. comes with a free upgrade to Serato DJ Pro, preserving the concept of the flagship DJ-808 and streamlined DJ-505, and allowing unparalleled flexibility to DJ, remix, and produce beats on the fly while performing live or creating in the studio. The DJ-202 packs in the most features of any controller in its class, with its large, low-latency platters, dedicated pad and transport controls, onboard sequencer, and mic input with professional vocal FX.

The DJ-202 is a two-channel, four-deck controller for Serato DJ Lite, with a free Serato DJ Pro upgrade included with purchase in the U.S. only. Its large platters have the lowest available latency, optimized for scratching, and it features built-in drum kits from Roland's legendary pattern-909, pattern-808, pattern-707, and pattern-606, realized with advanced ACB (analog circuit behavior) technology. The eight sounds in each TR kit include bass drum, snare drum, closed hat, open hat, Tom, rim, clap, and ride.

The onboard sequencer controls Serato DJ's sampler for on-the-fly beat creation, and the compact, rugged, and lightweight design with easy-grab handles ensures optimal portability. The MIDI output allows for synchronizing external devices with tracks in Serato DJ, and the USB-powered connectivity provides simple setup. Users can connect the DJ-202 directly to their speakers or amplifier via RCA stereo outputs, and use Serato DJ to organize and build music libraries or integrate songs from iTunes, just by dragging a track to the deck, setting and triggering cues, loops, and samples, and applying basic FX.
