When this guide applies

Exact Fluance RT85N. A different source is already connected and known to have stereo material; no recabling or contact cleaning. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Turntable / phono audio. Symptom: Sound plays from only one side.

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.
