Question about NAD C320 2-Channel Amplifier

1 Answer

Cuts out when volume increased

When I turn the amp up loud enough to annoy the neighbours it cuts in and out, in time with the bass. It's as if the speakers are drawing too much current, they have been ok for 5 or so years though, it's only just started happening. Could a capacitor have gone or something?

    Thanks for your reply. The cables are ok, as are the speakers. In my opinion it doesn't seem like a protection mode as all the lights on the front of the unit dim, and the sound goes crackly. Any other ideas would be appreciated.

It went to protection mode check your cables first and then check your speakers-and confirm no cable touch each other(try with another speakers had same rating)(watt)--means how much power can get.

I have a 1200 watt sony xplod amp hooked up to a 15" SBL Gorilla sub. The bass hit for a while and then started to cut off. Now it wont work unless i touch the remote wire to the power wire, and even then...


this kind of problems usually happen when the amp is not getting enough current to power up the  
 amp. the moment a loud low frequency hits the amp it fails. cud be ur power unit not giving enough power to the amp or u have a loose connection somewhere on ur power line. besides 8gauge is a bit small. try using about 4gauge. should have good ground too. they draw large current so ur battery should be in top condition as well.

Right channel cuts out,usually after listening to music loud.Usually happens when amp is warm


Most likely a loose connection/dry joint inside

Check all exterior connections first.

If amp has pre out power in connections the try driving another amp from pre out stage.
Try driving power in stage from another source.
Swap round inputs to check preamp section
Always start at low volume, check sound is ok at low the make it loud.

Write down results of all tests, it will save time and money at the repair shop

Gemsound power amplifier exa3955 keeps shutting off.


it is most likely that the shutting off is an precautionary system response to protect your amp and drivers. check all connections again for wrong polarity.

Peavey TNT115 AMP cuts out


The problem is in amplifier section caused by change value resistor or leak capacitor or cold ,loose or crack solder joint parts this the common problem of over heating and shuts out the amplifier caused by abnormal distribution of current,try to check all the capacitor and resistor and replaced the defected parts ,so your receivers works normal again.

Hope it may help you;

Sonamp 260 cuts out


Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.

Amplifier power cutting out


not enough power to amp and or amps location is too hot might want to invest in a couple cooling fans from computer store and attach where needed

an amp should take up to 3/4 load but when not enough air to it to cool it off it will shut down

try this turn gain all the way down and slowly work up too desired amp volume setting

Sounds like you like your music like me... LOUD. If you've done this a number of times, there are a few things that can happen:

1. You've blown the speakers... but you've said it operates for 2 seconds, then cuts out.
2. You've damaged the amplifier modules within the amp and they immediately overheat upon power-up. Does the music come back like 5 or 10 seconds after the unit cuts out?
3. Thermal switch has malfunctioned and just cuts off the power to the amplifier modules as soon as it sees any heat.
4. If you've gotten the amp really HOT during playing, it's possible that it's as simple as the amp modules are only intermittently connected (fatigued/stressed or cold solder joints) at the on the PCB. Just resolder the connections of the amp module to the PCB. I've seen that happen numerous times and that's where I'd place my money.
