When this guide applies

Exact M10 V3 and a turntable’s cartridge/output mode are positively known from its own instructions. Pause playback, reduce volume and power off associated equipment before changing RCA connections.

Connection scope: 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.

Checks and possible outcomes

LINE IN is for a line-level source. A turntable with an enabled built-in phono preamp is already sending line level. Use PHONO IN for the known unamplified MM signal, or LINE IN for the already preamplified line output. If the cartridge is MC or the mode is unknown, stop and obtain exact compatibility guidance. After restoring the normal system, select the matching Phono or Line source and replay at a safe low level.

Identify whether the turntable signal is already amplified

M10 V3 PHONO IN is for a Moving Magnet cartridge-level signal. LINE IN is for a line-level source. A turntable with an enabled built-in phono preamp is already sending line level.

Look for: Cartridge type and turntable output mode are known.

Possible result

Checks completed — report the actual outcome

The stated observation was confirmed in this setup. Completion is not an automatic Solved report, a hardware diagnosis or a physical Audio Review test.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Keep the observation for support

    Record the exact model, source, connection and last visible result. Do not reset equipment, open its chassis, bypass protective limits or install firmware to compensate for an unconfirmed result.
