Once you’ve got your tracks playing in sync, cue points and loops prepared, it’s time to consider the audio output.
In order to cue up a track and hear its audio, you’ll need a sound card with at least four outputs - two for the stereo master output and two for the stereo cue output. Open Traktor’s Preferences and select Output Routing.
Using Internal Mixing Mode, assign the output channels and monitor channels for your soundcard. Consult the manual of your soundcard to correctly assign the Output Monitor to the headphone output.
Pro tips: If you’re using an external mixer such as a Pioneer DJM, you can use External Mixer mode to send individual deck outputs from Traktor into a channel on the mixer. This way you can use the mixer’s crossfader, volume faders, effects and so on. Click on ‘External’ mode in the Output Routing settings to set this up.
