Question about NAD C315BEE 2Channel Amplifier

Open Question

NAD C316BEE amp comes on at 85% full output after changing speakers with amp in standy mode

The amp seems to be working. However, when playing a CD through the matching C515BEE player, the output loudness initializes to approximately 85% on startup, and cannot be turned down, by means of either the NAD remote or manually. Turning the volume up does increase the output sightly to maximum. This fault occurred after changing speakers with the amp and CD player turned off using the remotes (Standby mode), but not unplugged. Has the amp gone into "protect" mode, and if so, how do I reset it? I find it curious that I still have output, just not controllable output. Any helpful info or suggestions would be much appreciated. Thanks.

sounds to me that the vol control has lost its earth end connection So yes its a problem with the dial control You couls try some contact cleaner But better still lift of the lid and base if possible while the amplifier is not plugged into the power socket and see if you have a dry joints around the vol control pot regards Trev

I have had the same problem which required a replacement motorised pot. I've also had a small cap fitted next to the heatsink on the positive rail regulated supply transistor go pop! Bad smell, protection circuitry operates.
Great amp, great design, poor quality assembly and QC. NAD need to lift their game!

take audio out from tv and insert it in aux in in your amp.

Since the problem seems to be sensitive to the volume level, I would be looking at the output wave form for any DC current. Although the protection circuit should detect any DC present, it is possible that some is leaking through. Also, verify that the speaker impedence is correct. If the amp is seeing too low an impedence load, it will work too hard causing excessive heat which will shutdown the unit as well.

Keep me posted.

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

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.

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.


Hello
Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

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.

Standy mode system wil not turn on


When you connected the speakers, one of the following may have occurred: 1) Crossed the wires (smoked the outputs) 2) Presented too low an impedence load to the amp section (overheated and smoked) There are other possibilities as well, but those are the most common. In any case, try disconnecting hte speakers altogether and trying to turn on the system. If it turns on, then the problem is either the wiring or a bad speaker. If the system stil won't power up completely, then the output section needs to be checked. These units have discrete output transistors that can be checked by a service shop. These are not too expensive but are somewhat unique to Aiwa systems. Figure on $20-$40 for parts. Dan

Amp c352 TI 1515456 failure


It sounds like yo shorted the speaker wires together for a short time and smoked the output section of the amp. The amber light is an indication that the amp is in protect mode. If you attempt to power up the amp and still have the amber light even with all speaker wires disconnected, the amp needs repair. The output transistors for that side will need to be replaced.

I have an av316 NAD, surround sound Amp. Just got back from repair. The wires to the speaker may have been reversed when hooking, the amp went into protection mode, can I fix this problem. It wont come out...


Having the speaker wires hooked up backwords will not cause protect mode. If the wires were crossed (in other words shorted), that would. Disconnect all speaker wires, if the unit is still in protect mode, than the output transistors are probably shorted and the unit will again require service. Upon return from service, I would turn on the unit without speakers to insure that the unit at least works that far. Also, if you have an ohmmeter, measure across the speaker terminals. You should read either 3 or 6 ohms. If you read 0, the problem is a shorted speaker that then shorted the amp.

Keep us posted.

Can I connect a power amp to this unit?


If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.

So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.

Turn it up!

Nad c370 problem....


Hi arda5
Did you try swapping speaker connections left for right on the back of the amp to isolate the problem. If the fault stays with the speaker, then that is where your problem is. Try this and get back to me here with the results.
