How to fix no computer audio on NAD C 390DD?
If your NAD Amplifier isn't producing audio from the computer, make sure that your PC or Mac's Sound or Audio device setting is set to “NAD USB Audio”. Also, confirm that music files are being played back from your computer.
Why is the VFD dim on my NAD C 390DD?
If the VFD on your NAD Amplifier is dim, it might be due to a low brightness level being selected. To fix this, toggle the [DIMMER] button until you reach your desired brightness level.
How to turn on NAD Amplifier C 390DD?
If your NAD Amplifier (C 390DD) won't power on, check that the rear panel POWER switch is set to “ON”. After that, press the front panel Standby button.
What to do if my NAD Amplifier C 390DD remote control is not working?
If your NAD Amplifier (C 390DD) isn't responding to the remote, first, verify the batteries are working correctly and properly inserted. Next, ensure that nothing is blocking the infrared receiver (IR) window on the C 390DD or the IR transmitter on the remote. Also, reduce any bright sunlight or ambient light hitting the front panel of the C 390DD. Finally, check that the IR Channel setting on both the C 390DD and the remote control are the same.
What to do if NAD C 390DD Amplifier shows 'No files found'?
If your NAD Amplifier's VFD displays “No flies found” even with a USB device connected, it means that the USB device doesn't contain any playable MP3, WMA, or FLAC files. To resolve this, load MP3, WMA, or FLAC files onto the USB device.
