When this guide applies

Exact Yamaha R-N800A. Known stereo source and wiring; no speaker cable reconnection or cartridge rewiring. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Analog line / headphone 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.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

Confirm the exact setup

Pure Direct is already OFF, the source has both channels, wiring is known correct and the owner accepts centring an unintended balance offset.

Look for: Choose only a detail you can confirm.

Possible result

Confirm the unknown detail first

Do not infer a source setting, installed cartridge, connector role, software state or partner capability. Obtain the exact documentation before continuing.
