Traktor + S4 MK3: input selectors and outputs
These are general checks, not model-specific compatibility certification. Start at low volume and change one setting at a time.
Check in order
- Check computer connection/power and ensure a software-playback channel is not routed to an external THRU source.
- Select S4 in Audio Setup; for normal controller mixing, check Internal mode and master/monitor assignments.
- MAIN and BOOTH have separate outputs/levels; raise the control corresponding to the connected speakers gently.
- For CDJs, mic or DVS inspect the physical input and Input Routing; do not copy MK1/MK2 channel numbers onto MK3.
- If unresolved, record models, OS/app versions, OUT-to-IN routing, the last responding meter and comparison results in the support note.
Controls do not respond
- Check USB recognition and deck assignment first; audio routing is separate.
Controls work but audio/cue fails
- Start with Audio Setup and Output Routing, distinguishing master from monitor.
If unresolved
Record hardware models, OS/app versions, the last responding meter and test outcomes for official support. Do not infer hardware failure or a purchase requirement from unverified checks.
