Why does the Power/Stand-by/Protection LED turn red on my NAD Amplifier?
- MMark WiseAug 1, 2025
If your NAD Amplifier shows a red light on the Power/Stand-by/Protection LED during operation, it indicates that the amplifier has overheated or the impedance of your loudspeakers is too low. First, turn the amplifier OFF and check that the ventilation slots on the top and bottom are not blocked. Allow the amplifier to cool down before turning it back ON. Also, ensure that the overall loudspeaker impedance is not below 4 ohms.
