Nad C320 right channel stops working then comes back again
Hello, I've had the amp for a few months, worked fine until now the right channel stops working after a few minutes. if i turn it off and on again, both channels will work for a little while, but then the right one dies. I tought it was somehting with the cables, checked them and they seem ok. also, the same thing happens if i put headphones into it, so i'm guessing it's a sort of an "input" problem.

Did you try to switch the loudspeakers? Before changing anything always lover the volume and switch off the amplifier. Assuming you tested already different inputs, you can be sure no cable from signal source is out or defect. (or did you nit check that first?). When the amp is switched off, disconnect the speakers and switch left to right and right to the left output.. If the other speaker is quiet now, you are sure it is in the amp. Still his can be anything. You can check the connections between the pre and main amplifier on the back side. When you have an extra set of interlink cables, perhaps you can cross the in and output there too. Take care every time you change something, lower the voltage and switch off the amplifier. Sudden clicks when switching on or changing anything can damage the amp and or the speakers.
Perhaps when you checked this you can locate where the problem is? Speaker, speaker cable, power amp, pre amp, (only a part of the pre amp.
well..this is one for the books. Can you tell me what the ratings are between the 252 and the 752 impedance matching wise? even though it might work sometimes, impedance matching can wreak havoc between mismatched amps.
You will need a cable with headphone jack (for mp3) and RCA left/right to connect to your NAD 320. You can connect to CD or AUX in the back and then you will need to change the input with remote or with on board buttons to CD or AUX depending where you plugged it.
Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.
Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???
yes send it back chances are there could still be a warranty on it and that should be covered by it dont mess with it that could invalidate the warranty even if its not in warranty to replace the switch wont cost much.As for the contact cleaner be careful it is flamable and an arcing power button could ignite it do this with the unit unplugged but also make sure its dry after too do not do this unless you find the warranty has expired. Hope this helps
