Why does the power/protection LED turn red on my NAD C320?

  Larry 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.

  If your NAD Amplifier has no sound, first check if the AC lead is plugged in and the power is switched on. Ensure that the Tape 1 Monitor mode is de-selected and that Mute is switched off. Also, confirm that the rear Pre-out/Main-in amp links are fitted and that headphones are disconnected.

  If you're only getting sound from one channel on your NAD Amplifier, start by centering the Balance control. Then, check the speaker connections and the speakers themselves for any damage. Finally, inspect the input leads and connections to ensure they are properly connected and not damaged.

  If the remote control handset for your NAD Amplifier is not working, start by checking or replacing the batteries, ensuring they are correctly inserted. Next, verify that there are no obstructions blocking the IR transmitter or receiver windows. Finally, check if the IR receiver is in direct sunlight or very bright ambient light; if so, move the unit away from direct sun or reduce the amount of ambient light.
