The Allen & Heath Xone:DB4 can de considered as one of the most elaborate DJ mixers/controllers of the moment. It has tons of functions like a 3 band EQ and a 3 band Filter, an effect processor for each channel, a built-in audio interface, and so much more. To me, personally, it is a mixer of 'the next level'. To mention just a little detail, the Xone:DB4 comes with its own HQ carrier-bag. Little details like this tells you this is more then just a mixer.
