To set up direct audio input via USB for the DDJ-XJ, DJs need to ensure that their computers have the necessary drivers and that the Serato DJ Intro software is installed and updated to the latest version. Once connected, the software recognizes the controller, and the audio signal can be routed directly through the DDJ-XJ.
