Obnoxious static noise coming from studio monitors

[Hund]

I recently purchased two active studio monitors (Yamaha HS8).
The monitors are great but a weird high pitched static noise ruins the fun

The static gets louder when I turn the volume knob on the speakers up. (on the in built amplifier). It does not get louder when I turn my system volume up.

Also I can 'trigger' the sound with the mouse. Everytime I swipe the mouse cursor over the screen the static becomes louder.

I gets really loud and obnoxious when I start a CPU heavy program or a game.

I hope there is a way to fix this

Sorry for my mediocre english.

It sounds to me like there is interference coming from somewhere. Where are the speakers, sorry it is hard to call them monitors, positioned?

Yeah sorry i meant to write speakers instead of monitors.

They are on the table above my pc tower.

Try, just for laughs, turning off the monitor but keeping the speakers on and see if the sound persists.

Just tried that + I unplugged all my USB devices but the sound is still there.

Ok so we have removed those. Does the sound persist when unplugged from the sound port but still has power plugged in?

When I unplug the from my usb audio interface the static goes away and just a small ac hum remains.

I just tried to use the interface with a different pc and I did not get any static.

So I'm guessing it has something to do with my pc built?

It might be the port you are plugging into. Is it a port on the back of the board or the front? Some cases have horrible shielding for USB and some motherboards do as well.

It is plugged in the back panel.
Mhhh. Unfortunately I dont have another mobo to test it

Try a different port. Is his going into a USB 2.0 or 3.0 port? How close is it to other items that are plugged in?

This is why I stick with 3.5mm, less chance of interference.

Tried it with every USB Port now and unplugged everything else. Even the ethernet cable. The static still persists.

I think it has something to do with my CPU since the noise gets louder when I run Heavy apps.

 

[jimmysmitty]

That is very possible. Most USB ports are connected to the CPU via the chipset so the CPU doing heavy loads can possibly cause it.

Have you tried connecting the speakers via 3.5mm instead to see if there is any interference?

They can only be connected via USB. Two 6,3 mm cables run into my audio interface and then from there into the USB port.

I wish I could try another CPU and Mobo

You could try to eliminate the audio interface. It will be a bit complicated of course. From what I have found online these speakers run on the 6.3mm jack, as you said, and you can buy a 6.3mm to 3.5mm jack and plug it directly into the sound card. You can do it for one of them to test it to see if the interference goes away. If it does then we can look into a way to hook both of those up to a receiver that have 6.3mm then port that into either the 3.5mm on the sound card or the optical out on the sound card (if your boards sound card supports that).

Something like this:

That is a good tipp actually. I'm going to try that. I don't think that my audio Interface causes the problem since it works just fine with my other pc. But it is definetly worth a try! Thanks

Hey man.

I have the same problem. I do recording and I'm all into computers and stuff and I cannot figure this out. I have went so far as getting a new computer 3 times. I've changed my speakers, interfaces, apc ups back ups, and all kinds of other configurations. I'm starting to really think it's my house. A lot of people here found solutions like downgrading their interfaces or trying the 3.5mm thing but all your doing is lowering the quality of converters and preamps in your devices so they don't require as much power as our good stuff, and then their noise goes away. But we like our high end, heavy power load stuff, so we need to figure out how to fix this without downgrading our stuff.

PROBLEM FIXED: I was pretty concerned because I bought the HS8's a month ago. I was ready to send them back. I found a guy who knew a little something about something and he guaranteed me that if I went out and got a set of balanced cables (10.99ea) the problem would go away. So I ran over to my favorite music store and go some balanced cables coming out of my Focusrite, going into the XLR of the HS8's. The speakers are completely silent now. If you are using cables with a single sleeve, you will definitely have this problem. Answer: Get the proper cables and the problem goes away.

I FINALLY FIXED THE PROBLEM.

I tried everything you guys suggested but the solution was waaay simpler.
The problem was caused by my wall socket. It just connected each speaker to a different socket
(further away from the socket the pc is connected to)

I could have tried that earlier
