NAD T955 amp has dropped a channel, when i turn it on the led starts off blue instead of red, when the other channels change to blue from red it emits a loud POP noise from the lost channel. No noise comes from this channel when played, The speaker works fine on other amps and other channels. no speaker will work on that channel, it is dead.

BOTHE ARE BACK AT LENBROOK AGIN FOR THE 3RD TIME. 3 MONTHS OLD, 2 MONTHES AT HOME ONE MONTH AT LENBROOK. I THINK THE COMPANY IS GOING TO BE OUT OF BISINESS BECOUSE THEY MAKE THEM IN CHINA WITH COUNTERFIT COMPONENTS. I ALSO HAVE ANOTHER T955 SO I CAN BI-AMP BUT HAVENT HAD A CHANCE TO BECOUSE OF THE PROBLEMS, THE FIRST AMP WHENT THE DAY I GOT THE T163 BACK AND PICKED UP THE SECOND AMP.

    I have owned an NAD T955 for 4 mos.. Yesterday, channel 2 failed in exactly the same way you have described. I hope NAD can offer some help, because this seems more than just a coincidence to me.

    Same problem here on the center channel! If I play pink noise through the amp it does play the sound for half a second before the pop then the channel no longer outputting sound. Whats strange is you'd think the protection led would turn red.

    I have owned an NAD T955 for 5 month. The left rear surround not working and the led is blue alwais. And it´s emits a "POP" when I turn on. It´s now at technical service.

    Hello, I have purchased 2 T955 power amps, one does lo pass and the other for hi pass. The lo has channels 2, 4, & 5 blown and the hi has channels 3 & 4. That is half of my 10 channels! I am pissed of with NAD with expensive amps being built in China. I am going to have a good word with the distributor tomorrow. I bought one in Melbourne and the other in Sydney. I am a very unhappy consumer.

SOURCE: Loud distortion on Front Channels

Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd

Hi ! Check and make shure that the cord conections between the pc board on the backplate of the amp to the logic board are firmly pushed in there slots.
Good luck , Stefan from Sweden

SOURCE: I have a Fisher RS-717 stereo receiver, amplifier.

Yes you can use either A or B without a problem. The restriction is when you have both A & B connected. In that case, the speakers MUST be a minimum of 8 Ohm impedence. Using either A or B, you can use speakers of 4 Ohms impedence.

Nad C350 2 channel Amp continually in protection mode


That could indeed be the issue, but you must check your speakers, wiring, and also the oupt stages for problems. Maybe the prtection circuits are actually doing their job. lol

Hope that helps...

I run a sub and two sets of speakers on speaker B of my NAD C740 through a speaker selector. I think there has been a short circuit caused by the + and - wires touching. The left channel no longer works on...


Check that both left and right channels work on A speakers. If they do, the amplifier is probably good and your problem may be outside the amplifier. Try swapping the left and right speaker connections at the back of the amp to see if the problem changes from left to right. this would tell you if the problem is in the amp or out to the speakers. Hope this helps

NAD 7020e sudden volume drops, sudden distortion- intemittently


OK. I dont know the answer to your prob, but to let you konw that youre not in this alone, my amp used to occasionly lose considerable volume in one channel. this could be remedied by cracking the volume up to max for a half second or so. (Not a great solution!!) It has finally given up the ghost ...I have lost one channel and the doctor says it wont come back. Not only this but they claim that spares ceased to be sold back in the 90's. having said this I have enjoyed this amp for almost 20 years. I think its time to put it to pasture.

How do you connect power amp to av


I presume you want to use it to drive speakers from a source controlled by the Denon??? Probably the Front channels? We'll assume that's it...

Run RCA cables from the Pre Out jacks to the NAD's L and R inputs. If it has a volume control, set the NAD to its maximum volume (for consistency *), run through the setup for levels and you're done.

* If it doesn't have a volume control it's already set to max. That's normal for power amps. Your receiver / preamp controls the volume fed to them.

BTW: If you're thinking of using two sets of Front channel speakers simultaneously you'll have to choose a level on the NAD that will match up with the others in volume.

Nad 310 blows fuse in left channel at turn on.


Hi, Unfortunately, this means that the output transistors on the left channel have blown. I've rebuilt a couple 310s, and I own one myself, so this isn't the first time I've seen it. The chassis doesn't ventilate the left channel as well as it does the right, so it tends to die sooner.
If you can do this yourself, it will not be terribly expensive, but the main output transistor is a MOSFET, which means you'll have to be very careful about static, and you'll have to find a substitute for it as well, as it is no longer available.
I strongly recommend replacing the small electrolytic caps in the amp too. By now heat and age will have taken their toll on them. In my 310, replacing them wasn't an option to get it to behave well.

Right Channel Not Working


I have had the front, left and right channels go out over time. I have fixed all of them, and each time it has turned out to be a cold solder joint. While I love NAD and will continue to purchase there equipment, this generation is plagued with poor workmanship.

To fix the channel going out, I removed the top cover. Back cover and 2nd card from the left (looking at the receiver from the back side). This card handles all of the audio processing. I have found cold solder joints all over this board which has caused channels to suddenly go quite. I have never found a bad component. Also, I have cleaned the interconnect to be backplane (board that the audio processing board connects to) in the case of the center channel going quite.

If you have poor FM reception, the first board from the left (looking at the receiver from the back side) may have a cold solder joint on the coaxial connection for the FM antenna.

NAD CI 9120 (12 Channel)


Check all your cables, not likely but just in case.
Try removing all but two. Left and Right. Does it still happen,
If you can identify the speaker channel try swapping the speaker if possible.

It sounds like one of the speakers has an issue, could be a short in a cross over or speaker coil. If true the speaker is drawing too much current and causes the protect circuit to trip.

Depending on the quality either replace the blown speaker driver or purchase new ones.

If the speaker is not the issue it could be an issue with a power amp. Best to take it in for service.
