Reply to Setup Help!

So I'm new here, in a matter of fact I'm new to djing in general. But here's the deal. I own a Hercules Air and I want to upgrade to a newer setup. I want to use the traktor x1 mk2 as decks and a cheaper mixer than the z1 since It is over my budget. I found a $100 mixer and I'm curious to how I can set it up. I heard I'm going to need an additional soundcard but i m not sure. The mixer is called the Stanton m.203. Any advice would help. If any question, ask.
