Allen & Heath's Xone:K2 is a compact, slim line universal MIDI controller that incorporates a 4-channel soundcard, for use with any DJ software. Quick and simple mapping lets you create a unique layout that mirrors your style and puts the functions that matter at your fingertips, while 3-color illuminating switches give at-a-glance feedback. Xone:K2 has 52 physical controls, including 12 analog and 6 endless rotary encoders with push switch, 4 linear faders, and 30 backlit performance switches, providing up to 171 MIDI control commands across 3 layers. What each control does is entirely up to you. You can create a completely customized layout that perfectly fits the way you want to work. By assigning controls to multiple layers you can give a single physical control up to 3 functions. You can configure all, some or none of K2's controls to be linked to the latching layers system. Xone:K2 has a high quality internal, four channel (2 stereo) soundcard. Setup options include using the Xone:K2 with headphones, headphones and a mix/PA system or with an external mixer. Its slim line chassis and soft touch controls set K2 apart from the pack. Xone:K2 is built to Allen & Heath's renowned touring grade audio and build quality standards, including the use of steel nuts on all rotary controls to protect the circuitry from impact damage. Xone:K2 comes packed in a durable black padded case as standard. As well as keeping it safe on the road, the case doubles as a stand, bringing the K2 up to the same height as most pro DJ mixers. Two K2s can be linked via Allen & Heath's X:LINK protocol, giving twice as much control capability. X:LINK uses a standard RJ45 connector and distributes power and data, which means two K2s can be connected to your software using only one USB port on your computer. X:LINK also allows connection to Xone:DB4 and Xone:DB2 mixers, offering further expansion.
