A good way is to buy a small USB PA mixer (my personal favorite currently is the Yamaha AG06). Run your master out from the DJ mixer to the PA mixer, you can now record in Cubase (the mixer comes with a copy) in a very high quality.
A separate, small PA mixer is always a good piece of gear to have in your DJ toolbox.
