Why does the power/protection LED turn red on my NAD C320?
- LLarry GilesJul 26, 2025
If the power/protection LED on your NAD amplifier turns red during operation, it could be due to overheating. Turn the amplifier off and ensure that the ventilation slots on the top and bottom are not blocked. Allow the amplifier to cool down before turning it back on. Another cause could be that the overall impedance of your loudspeakers is too low. Make sure the overall loudspeaker impedance is not below 4 ohms.
