I am completely new to Traktor and have just bought the Z1, X1 & F1 but need some help setting them up. I have installed the Controller Drive so they are all active. I would like the audio to come through my computer speakers, currently it only plays via the headphone jack. I see there are left and right audio jacks in the back of the Z1, do I just need a cable which combines these into a single cable that plugs into the headphone socket on my Mac? If so, what is the name of the cable? Cheers in advance for your help!
