Amplifier sound difficulties

My amp is only giving a extreme low sound. You can barely hear it even when the guitar volume and amp volume are all the way up, at overload/overdrive mode! I tried a new amp chord but no use, what is wrong?

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.

Bass and treble controls


You should check the Direct button is pressed or not.
In Direct mode, it by passes the treble and bass circuitry so you will not hear any difference even if you turn it.

Volume at 10 produces very low speaker output.!?


It sounds to me that all you are getting is the pre-amp stage of the amp and nothing from the power amp stage. As it is on both channels then it is something that is common to both. This could be something to do with the power supply of the power stage. Or whatever is on the heatsink. It could be that the amp uses a single audio amp IC for both channels. If it does my bet is that it's gone. If it uses two sets of semiconductors for the right & left channel it would be highly unlikely that both channels have gone, but not impossible.

Hi, Peavey Classic Guitar amp , Has NO SOUND


Hi Mike,

If you switch on the amplifier, do you hear nothing at all?
Or do you hear low level noise or hum out of the speaker?
Don't know if you're technician.
If the tubes are glowing, you can measure the high voltage.
Check also fuse 3 and 4, thats the neg. voltage -27V and -14V.


regards,
Gerard

When plug in guitar to amp, there is either no


Try a different guitar and cord. If still problem, give the amp a bump without guitar plugged in. If amp makes noise, there is an intermittent internal connection,

Amp works on off on off


The buzzing is possibly the electrical mains hum at 50hz, all amps have a hum/buzzing... if you have to tap the jack lead between the guitar and amp it could simply be a connection problem, the cable may be old and internally damages, maybe loose wiring on the other side of one of the input jacks

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.
