Babyface Pro FS: connection and audio troubleshooting

Model: Babyface Pro FS

1. Distinguish Pro FS from older Babyface models. Feed DJ left/right into separate LINE-capable inputs; for AN 3/4 verify side-input reference levels in the manual.
2. Check the corresponding top-row Hardware Input meters in TotalMix. If silent, investigate cable and input level first.
3. Select the same stereo input numbers in the recorder. Audible TotalMix monitoring does not prove those inputs are selected in the app.
4. Software Playback and Hardware Outputs are separate rows; distinguish the speaker submix from recording input selection.
5. For doubled monitoring compare direct and application paths separately. Enable Loopback only with a clear route and avoid feedback loops.
