Our thoughts:

NI scaled down their immensely popular S4 unit to provide a fully comprehensive 2 channel DJ controller for Traktor.  We love the portability of the S2 and the quality build of its components.  Definitely a top contender in the DJ controller department.

Manufacturer's notes:

TRAKTOR KONTROL S2 is the most professional 2-deck controller on the market. With pro credentials throughout, the 2.1 design couples the most essential items for any DJ — 2 decks and a mixer — with controls for multi-effect units and a third channel for samples. Set it up in an instant and dive right into the mix.

TruWave colored waveforms let you see track positions easily, and identify high-energy sections or breakdowns ahead of time - so you can plan the perfect moment to drop your next track. And with the advanced sync engine, your beat-matching will be locked down every time.

This compact and portable unit was built by the same team and with the same components that brought you the TRAKTOR KONTROL S4 – the wildly-popular market-leader that revolutionized the all-in-one DJ system. Robust knobs and backlit buttons let you know what’s going on at all times. Two high-quality, pressure-sensitive jog wheels deliver total track control and easy pitch bending and tempo nudging.
