When this guide applies

Exact Rega Planar 1. Existing connected vinyl system; do not compensate a raw cartridge output with extreme amplifier volume. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Turntable / phono audio. Symptom: Playback is too quiet or uneven.

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.

scope

Confirm the exact setup

The actual installed cartridge and its MM/MC requirement are documented, the system is already connected, and all inspection can be done without moving live cables.

Look for: Choose only a detail you can confirm.

Identify the input receiving the tonearm leads

Read the actual socket label. A line-only AUX input is not the required phono stage.

Check the documented phono-stage type

Compare the actual stage specification with the installed cartridge’s documented MM/MC requirement. Stop if the stage, cartridge or any external stage route is uncertain.

Observe playback only through the verified matching stage

Keep the amplifier low. If the existing route is incompatible, stop for a correct connection plan rather than increasing volume or moving live cables.

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.
