Greetings

I just picked up a pair of Yamaha HS80M monitors but have been greeted with crazy buzz/hum when swapping them into my setup.

It seems that everything electrical affects it, too.
I have swapped over every cable, tried every power socket and combo I can think of and while the hum does differ, it is still very much there.
Maybe I have dirty power in my room - but why is it JUST these speakers that are affected by it so much??
If everything is unplugged from them, they are fine as silent as they should be. If I plug something in while it is off, they buzz a bit. If i turn it on, they buzz like hell!
Computer, PC screens, POD HD, interface etc. Everything affects it in some way.

Any thoughts? :(

I had some tapco S8s before these and they are fine

EDIT:
Seems a fair few people have this problem:
To Hell and Back w/ Yamaha HS80m - Gearslutz.com

I will some of the suggestions in this thread and see what happens. Don't want to remove my earth though!

What do you have the output level set to on the monitors themselves? Are they 100% cranked?

Shielded cable vs. Unshielded - is there a difference in the amount of noise?

Have you tried the XLR input vs. 1/4"?

Speaker output was set at 12oclock which is +4db I think? So not loud for them at all.

Cables used made no difference at all.

I havent tried XLR as I dont have XLR outs available at the mo. My mixer is a bit small and only has jack outs - upgrade for the future but not right now.

I had a look over the internet and found a few people with the same problem. Looks to be power related.

Best option is to reorganize all my power sockets so audio related things - speakers, interface, mixer - is all on 1 socket and the PC, screens and xbox are on a separate socket.

Another option is to remove the earth pin but I dont want to do that.

Yeah definitely don't remove the earth pin. You want them on different circuits if possible, not just different sockets. Ground loops are a giant pain in the dick.

This is the music gods way of saying "Finish the fucking Season's End album, Tim."
:lol: I KNOW :(

Damn singers needing to redo parts. Should never have let them do it.

When it's done, I'm going to delete it all!
