How t plug my F1 to a mixer

[brocklambert]

But i can't do that with a more basic mixer ? Like the DJM 300
So in these case (like the DJM 300) if i wannt to use traktor by pluging my computer to software i can't use the traktor kontrol F1 Without?/With an external soundcard

If the mixer doesn't have a built-in interface, then you need and external soundcard.
