When this guide applies

Exact Pro-Ject X1 B. Compatibility inspection only; no cable purchase or output route is assumed from an XLR-shaped socket. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Turntable / phono audio. Symptom: An option or codec is missing.

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.
