For those looking for a slimline and portable DJing controller that still offers plenty of flexibility, the Xone:K2 is a good option.
It might lack jog wheels, but the K2 packs faders and rotaries to control four mixer channels, and a grand total of 52 assignable controls. The unit offers lockable control 'layers' too, meaning that a total of 171 MIDI assignments can be setup and switched between at the flip of a button.
The controller features a built-in soundcard, meaning it functions as an interface for four channel mixing. The K2 also features a pair of X:Link connections, allowing it to be chained to other Allen & Heath units to form a fully synced setup without the need for extra USB and power leads.
The K2 comes supplied with mappings for both Traktor and Ableton Live, but it really comes into its own once you start experimenting and assigning your own setups - those looking for a similar unit for Traktor that's perfectly setup straight out the box may still find NI's own X1 or F1 better options.
