When this guide applies

Exact Audiolab 9000A. Read-only inspection; do not disable or raise the protective limit. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Device controls / power only. Symptom: Playback is too quiet or uneven.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
