When this guide applies

Exact NAD C 700 V2. The existing input is known and Hide Source is definitely enabled for it; no cable changes. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: HDMI / ARC / eARC audio · Optical digital audio · Analog line / headphone audio · 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.
