NAD amp distorting heavily after running a bass guitar through it.
My NAD 214 stereo amp is dead or dying. Any signal I run through it is
extremely distorted and I have to turn up the volume to even hear that. Beginning a few months back it would sound fine and then all of a sudden die and the sound would become horrible distorted. The time it takes the amp to go from working fine to distortion box continually shortens from 20 to 10 to 5 to 2 to 1 minutes. Now it doesn't work for anytime at all. I haven't been playing nice with it recently. I have run a microphone and bass guitar through it. However, the amp had experienced the problem I described above before this. So my question is this: Is there any fundamental reason why running a bass guitar or mic through this amp would hurt it? Also, does anyone have any idea what might be wrong with my amp. Thank you! -Jon Ps here is my setup in case it's helpful. NAD 214 Stereo Amp NAD 512 CD player Adcom preamp KEF Q55 speakers Monster XP cables |

This amp was not designed to be used as a performance type music instrument
amp at high levels, such as with a bass guitar. The constant power demand, must have over driven the output stage. The output transistors, pre-drivers, and some support components are probably damaged. When I was servicing these types of amplifiers, I used to see people damaging them like this from time to time. An experienced tech who is familiar with your amplifier model, with the proper test gear and setup, can service your amplifier for you. It is a matter of properly determining the damaged components, replacing them, and making sure that the performance of it is back to specs. A suggestion would be to get a proper bass guitar amplifier for playing your guitar. Use this amplifier for listening to general music at moderate volume settings, and it will give you good performance for many years without failure. -- Jerry G. ===== wrote in message ups.com...

Hi,
do (or did) both channels sound identical? If so there's a good chance you haven't actually blown anything up and it may be a simpler power supply problem. Gareth. wrote in message ups.com...
