    Thank you for the handy tip on how to fix my amplifier. I'll still have to take it to a registered Behringer repair man, but at least I'll be able to help him pinpoint the problem quickly.

Try unplugging cables from the inputs, one by one and see if the hum stops. If it does its a ground loop, if don't it could be a leaky filter capacitor in the power supply

Guitar amp continuous humming from speaker


Firstly, do not disconnect the speakers from the amp when it is on. Damage is possible.

You have a bad ground somewhere in the hookup. The first suspect would be your guitar-to-amp cord shielding connections at each plug, then, the wiring in your guitar. Try changing each of these to another as a trial, one at a time.

Humming when no input in jack; works fine with rca inserted; worries me that somethings is not right even though works fine with RCA or XLR plugged in, right channel only


Sounds like it could be feedback hum. Is there anything near it that could cause a reaction when unpluged? Such as a turntable, cassette etc. If so move them and see if it goes away. Even then it won't hurt the amp. I think otherwise worry when there's a hum when they are plugged in. PS check any earth connections too!

Adcom GFA 5500 'mechanical' hum from amplifier


Possibly. Most amps filter out line hum via low-pass filters. If you can locate a schematic, those would be the caps to check.

Marshall AS50R produces a loud hum with an intermittant loud click, even when nothing is connected. This happened after use with zoom g2


Sounds like a power supply filter cap has gone bad.

The hum you're hearing could be the 60 Hz AC, especially if it is a low frequency.

If that IS what it is, the Zoom G2 was just a coincidence.

A23 AMP


If the amp hums with just speakers connected and no inputs. The problem is internal and Parasound should take care of it under their usually prompt warr. service which is still in force. 5 months sound odd. Was your dealer getting it or was it direct? If not them connect one component at a time, add preamp next(nothing connected to it). If it hums them use a 3-2 ground lifter on the AC cord of the amp and do not connect the wire to the outlet screw. If not them connect each component. If you have cable very often this will cause hum even if you are not listening to cable sound. Use a ground isolator in line with the cable RF input.
