SOURCE: No signal from sub connected to NAD T760 in test mode.

Try using front pre out to the sub from the receiver. the crossover is in the sub anyway. If this works change your settings on the receiver and test again. If sub is still inop, could be an internal issue with the sub amp. Does your sub amp have an on/auto/off switch or light? check that as well. Hope this helps, if you need further assistance, send a reply and I'll help some more

SOURCE: my nad amp wont turn on - i've checked plug fuse so it must be something inside - was told it might not be worth fixing but i wuld like toknow what it is so i can at least decide. it's only 2 years ol

Yes it could be the internal fuse. If your lucky it might have just failed on it's own!

SOURCE: My NAD cd-player has locked it self! I cannot play

Mine does the same. Press eject and give the front of the draw a sharp tap.. the draw should then open.
Also when loading a disk give the draw a hard shove closed just as it is almost shut - seems to make the disk read ok.
I think both problems are related to a worn / slack tray drive belt... I just haven't been able to find a replacement.

Sound distortion with NAD T 514...


You are probably clipping in that midrange. Since the DVD player is fine and CD player is distorting: they are line level outputs, If you are running those through an equalizer- the equalizer should allow you add in a 10db attenuation.

If you are running them straight to the amp, The CD line level output should be about 1.5 volt peak to peak, it may be the line level input of your amp is only 1 volt and the DVD player simply has that level of output so does not clip..

Simply adding into the cable a 0.1 microfarad polyester capacitor for each channel should be enough attenuation to avoid clipping. The midrange is where you hear the most content in large part because that is the range that the human ear is most sensitive to. Which is why that portion clips. The DVD audio is actually recorded to the same specs as CD audio. You can confirm this by playing your CD disk in your DVD player. .

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 have a NAD C315BEE which is about 2 years old. It has been connected to the same speakers, CD player and wall socket for all that time but has suddenly started making a buzzing noise through the...


I had exactly the same problem and quickly repaired it: One of the two 10000uF 50V 85C caps was open circuit; replacing both of them solved it entirely. If you do this yourself, be very very careful to prevent shock.

NAD T751 constant buzz


It is a known problem with this model. The source of the buzz is the Dsp power supply. On the DSP board itself there is a 2200my\f/16v capacitor that is defective . Usually the capacitor will turn brown and swells due to overheating. Replace it with a higher temp rating capacitor with the same capacitance and voltage specifications.
