    Hey world

    I'm currently using a pair of Yamaha HS8 monitors connected to a Focusrite Scarlett 2i2. (balanced cables)
    But I'm getting a weird noise almost like a white noise but not as sharp, from my tweeter. Along with a sub noise coming from the sub part of the monitors. The noises aren't too loud, but they are definitely hearable, and after a while it get a bit annoying.

    I was wondering if anyone knows a solution to this kind of problem?
    Thanks!

    First off you need to narrow it down. IE does it happen when the cables you are using are not plugged into the monitors but the monitors are still turned on? Does it still occur with something else hooked up as a source signal to the monitors other than your interface? Does it still happen with different cables used to hook up the interface to the monitors (The area I personally would begin at and usually the most common)? Once you've narrowed down/trouble shot the offending bit of gear then it should be easier to resolve. Hope that helps for now :)

    Based on what you mentioned.. and especially if you hear fluctuating artifacts in the white noise you described.. 99 percent of the time the problem is a ground loop. And the cause of that problem in most cases is the computer power supply. Even the best power supply on the market can pair poorly with certain monitors. Just a compatibility issue sometimes. Use a ground lift plug adapter to turn the three prong plug for one of your monitors into a two prong. If the signal is clean when you do that then you have a ground loop. You can use ground lift plug adapters as a permanent fix for the problem. But if you're in the habit of turning your monitors on and off a lot, or plugging and unplugging a lot at the back of your computer you could catch an electric shock that would have you on cloud 9 for a few hours or potentially kill you. Use the ground lift plug adapter to test for a ground loop to say the least. And if you don't want to run with it as a permanent solution you'd want to look into buying another power supply, or shop for a decent power conditioner from Furman.

    The sound still continued, when I disconnected the cable from my soundcard to my monitor. But the sound was much softer, however still preset. I'll try ground lifting and let you guys know :)

    I had this problem with my HS80's, I found that by plugging the speakers into separte wall socket from my mac solved the problem, I used 2 4-way extension sockets so they could reach, problem solved

    What's the sensitivity level knob on the rear of your monitors set at? +4dB? If it's set at maximum [-10dB], try setting it lower, to +4dB, which is a mid setting.

    Like this:

    Level setting also depends on how loud you like to listen to the music. Boosting it to maximum can make most of the nearfields sound quite a bit more noisy, especially when it's quiet in the room.

    Cheers!

    Hey my monitors sensitivity is on 4db like the image you have provided. I've changed the room control to -2db but that doesn't seem to be the main reason for the noise..

    I've had some strange noise coming from one of my monitors, it was caused by the wi-fi, now that I've moved the wi-fi antenna the annoying noise have disappeared...

    When you disconnect your speaker from the soundcard and you still have the noise, try a different power outlet. Also unplug USB devices that are on that power outlet. I have a different 'power group' for my speakers in my studio just because of these type of problems. Also use good cables. dbmuzik also has good arguments.

    If you have them set on +4dB already then level setting is not the problem as they would make more noise at -10dB setting [maximum]. So it's probably the cables as the others suggested. To find out which ones are the culprit you can move them while listening to monitors. ;) Often times you can find the offending one more easily that way.

    Cheers!

    Hi, I've the same issues
    I tried to plug all the monitor(and sub) in a different power outlet but nothing...i keep heard noises (mouse tick,CPU etc etc)
    I tried everything...last chance is to use a DI BOX but am I sure to FIX the problem? I dont want to waste money.
    Thanks

    Personally along with the person I work with and who is my closest friend we use rack mounted mains power distributors with power conditioning (There are many to choose from, As long as you grab one that features a good say 10-amp circuit breaker, Surge/Spike protection, Peak voltage clamping plus RFI and EMI filtering, You should be good to go). I have two at the moment and could use another one, Anything that is on an IEC (kettle lead) gets powered that way, I haven't had many problems with nasty interference that I haven't been able to quickly isolate and eliminate. ART and Ebtech do really decent quick fixes for one off problems and if you do not have racks of stuff that need powering. These are what you might want to look into http://artproaudio.com/isolators/ http://www.ebtechaudio.com/hedes.html http://www.ebtechaudio.com/humxdes.html
    Hope that is of some help/use and all the best to all as always

    I landed on this page after searching google. Just today a slightly artifacted noise started coming out of one of my HS80-M's woofer cones; a very gently descending white noise with digital artifacts--barely noticeable but there.

    When I adjusted the rear sensitivity knob, the noise modulated like FM...sweeping up and down as I turned the knob. Is this interference? I haven't changed anything in my setup and have been noise-free for years, so I'd think sudden interference wouldn't be the culprit.

    Any ideas?

    Sometimes my cell phone will make noise in a monitor if I put it too close. But I recognized it immediately as GSM noise.

    Hmm, I can test that the next time I hear it. Thanks.

    If you disconnect the audio inputs and you still hear noise, it's most likely an issue with the monitor(s).
    Simple as that.
    I cannot remember a single case where bad power grounding or filtering was the cause for noise. Hum, radio reception, weird sounds yes, but not noise.

    I had a similar problem at a previous apartment. I was on an upper floor and a power line was outside my apt window. I realized it was either that or radio tower interference because as soon as I moved the issue dissapeared while using the same equipment.

    If its not the cable ...
    I had a noise problem once with a PC (mouse sounds while moving, mobile phone like clicks but really really quiet etc) Turned out the pc made this noises and put them through my usb connection. I used my Furman power conditioner which I have for playing live and all was quiet. Most of the the noise problems are caused by a bad powersource. Either on your monitors or on your PC/Notebook. Try another room or even place with your equipment

    Peolpe often underestimate good clean power. There are places were it is impossible to get "noise free" power without a conditioner/cleaner. All big studios have colour coded sockets. 1 colour for your mobile phone - the other colour (cleaned) for music related things.

    If everything mentioned fails to get rid of the noise
    You should rent a power conditioner or buy one (send it back if it dosent work) and see if it helps.
