If swapping of left and right input sources and left and right speakers does not help...you might have a bad channel in your amp.

SOURCE: NAD C320 BEE - goes silent. Only yellow light.

Hi,
Just came accross your post accidentically, while reparing my own C320BEE. May be it 's too late for you now, but it could help others: I had the very same symptoms as you described and after a long search found out that the trouble was R45 in one of the 18V regulators. (R45: 33 ohms 1/2W fuse resistor, situated more or less half-way between the two "metal towers" on the main board. Replace by a somewhat stronger type 1W or so.
Likewise R46.)

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 C320 outputs a very low sound volume


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???

I get no sound from my nad t175 preamp connected to a nad t973 (7 ch.) regardless of the media - rca, hdmi, et al. The fuse in the amp is fine, all the lights are working. Regarding the t175 i can see...


Possible that the amplifier has tripped and so gone to a protection mode. Remove power for few hours, press down all panel switches to drain off voltage from the processor. Also check for any short on the speakers before it is powered on.

Hi please help i cant find the specs for the C320


Not much - I saw one quote at 40, one at 50 watts rms. Strange that the manual doesn't include specs.

Connect subwoofer etc to nad 3020I stereo amplifier


Hi Info
You can use a 2 x male RCA to RCA female adaptor lead(what you need to ask for)  like this one 4d0dcde.jpg

use it to jumper your pre-out/main in connection on the rear, and connect an RCA lead to the Female socket on the adaptor lead. That will get you going. You can get them most places that sell electronic bits and peices. I am happy to answer any questionsa you may have

NAD C370 Right channel distortion


Sounds like you have lost the power amp transistor(s) or IC for this channel.

Gem Sound XP-350 both channels failed


Speaker fuses are generally fast-blow styles 250 volt glass
If an amp shuts down, with speakers connected, it sounds like one of the power supply lines does NOT like what it's "seeing" . Probably output transistors bad ( or module)

Take it to a tech.

Scott out.

NAD C740 no longer reproducing music through loudspeakers


what was your amp? ic or transistorized? the output transistor of your amp may be opened, mostly it will short but because u still hear sound, maybe open and only the driver transistor are working. replacing output transistor or IC could solve the problem.
