SOURCE: NAD C326BEE amp problem. Connected

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.

My NAD C326BEE amp goes into protection mode at moderate volume


The protection only should come on, when the power amplifier has to give more current than it can deliver. (electronic fuse)
If in the music is a lot of subsonic, sound, so low you can't hear and your speakers can't produce, this could cause the problem. Normal CD players will cut of all frequencies beneath 20 Hz, but it could be your PC is giving everything from 1 Hz and above.
I would certainly try to play some music over a CD player and check if that would solve your problem. Not sure if that works, what you could do to suppress the sub sonic in the computer music.

I plugged in my Nad amp to a socket last night, there was a flash of blue light and now it won't switch on. It is a NAD C316BEE Stereo Amplifier. Can you advise what has happened?


You need only look inside and follow your nose....The smell will lead you the faulty party, probably in the power supply. Just a power surge problem or something that's been going giving up the ghost.

NAD C326BEE amp problem. Connected to recommended Wharfdale speakers and NAD CD player and previously working fine for a year. Now red light flashing on amp and no sound when system is turned on.

I've bought my NAD C326BEE amplifier almost two years ago, and i got promised a hell of a good quality and that it would last for YEARS. But ever since i bought the damn amplifier, it has been shutting off...


Hi there,
I'm also a Nad fan. I find this pretty odd that you should loose two in such a short space of time. The cutting out is due to the "protection circuit". I would be inclined to get your speakers checked out as if they are faulty or not "matched" to the amp, it will trigger the amp to "protect itself" and shut off.

Need user manual for setup of the amplifier.


It should say next to the speaker terminals what impedance of speaker the amplifier is rated for. You can drive any speaker within reason with just about any amplifier as long as you are not trying to attain loud levels. Here is a link to the service manual for your amplfier. It states in the schematic power ratings for 2,4, and 8 ohm speakers so you can assume that this amplifier is compatible with those impedance speakers. NAD is generally known for their beefy amplifier sections. http://www.scribd.com/doc/7234868/NAD-3020-Service-Manual

I don't know of the availability of the schematics outside of service centers. Is there a specific problem? I have access to the service manuals but can not by contract send them out.
