PRIME 4 / 4+: standalone versus computer mode
These are general checks, not model-specific compatibility certification. Start at low volume and change one setting at a time.
Check in order
- Choose standalone Engine OS playback or supported computer-software control first.
- For computer mode connect the computer USB-B data port and follow the hardware computer-mode procedure.
- Mode changes affect playback; perform them outside a live set after stopping and preparing backup audio.
- Standalone audio does not prove computer-app compatibility; verify software/version and master/booth destinations.
- If unresolved, record models, OS/app versions, OUT-to-IN routing, the last responding meter and comparison results in the support note.
Track/USB loading fails
- Preserve drive/originals first and identify hardware/Desktop versions.
Playback works; output/mode differs
- Separate the playing layer, standalone/computer mode and physical outputs.
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.
