Fix my buzz


Hi , I have a new monolith 7x and I experience a ver loud hum from her when my dishwasher is running or my wife is blow drying her hair when either of these things are not happening it is extremely quiet, please how do I fix this. The amp is plugged directly in the wall but I do have a power conditioner which I plugged it into and it didn’t help 


Thanks I appreciate the explanation, I just replaced my mono block outlaw audio m2200 and with this monolith 7x and I don’t remember the outlaw amps buzzing as loud as the monolith, do some amps handle the vibration hum better then others? Or have a diffrent was of dealing with it 

@millercarbon does the leg of the panel that you have your system’s breaker(s) on make any difference? For example, if you had a heavy draw, such as a window AC unit on one leg, would it help matters to put your system’s breaker(s) on the other leg? I am thinking, from what you have typed, that it would not, as   both legs return to the same neutral?


Near as I can tell the noise is mechanical, caused when the transformer physically vibrates. Because of this different amps will sound different depending on things like chassis rigidity, type of transformer (laminated core, toroidal), how it is attached to the chassis (rubber grommets vs bolted direct), etc. Put it all together and one amp might make a faint hum only audible with your ear right up to it, while another might be heard to buzz like crazy from across the room. 

You could try changing outlets or breakers but the solution could also be as simple as unplugging the offending appliance.
