When this guide applies

Exact Audio Pro C20 W. Inspect and select only; do not move cables or alter a turntable preamp. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Analog line / headphone audio · Turntable / phono audio. Symptom: Sound goes to the wrong output.

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.
