Why is the PROTECTION indicator lit on my Yamaha CP2000 Amplifier?
- JJulia JohnsonJul 30, 2025
If the PROTECTION indicator is lit on your Yamaha Amplifier, it could be due to the heatsink temperature exceeding 90 degrees Celsius, or a DC offset of ±2 V or more detected at the amplifier’s outputs. Ensure the air vents are not blocked and improve airflow around the amplifier. If the issue persists, contact your Yamaha dealer or service center.
