Hi folks,
I'm getting the classic low level hum coming from my power amplifier and now it has started coming from my speakers (at a very low level). All cables are good quality and shielded where they need to be. I also have an IFI Purifier and an Audiolab DC Blocker which plug into two separate extension blocks simply as I only have two wall plugs that I can use within reach.
The hums are not volume dependent and I hear them with no volume, but on standby it's doing my head in. None of this occurred until I added the power amp.
Due to the positioning of my hifi rack (in the only place it can go as I have a large fireplace in-between the speakers), many cables do run in parallel although I do my best to keep speaker cables away from power cables.
I also have a student multiple occupancy flat through the wall and they i'm sure will be streaming multiple devices etc. etc. The flat is also old so the wiring may not be amazing.
Does anyone have any practical solutions (apart from move house)? Any info would be greatly appreciated.
I read that I can ground the chassis of the power amp but have no idea how to and I know it may actually be an issue with the transformer in the used amp itself.
Really weird that the speakers have started humming now without changing anything else. I never have them over about 1/5th volume, so i've not blown them and they can handle 120W. Plus i've no young uns who could've been playing with the hifi when i'm out!
Cheers,
A
