Tópico: Speakers making interference muffling high pitched noise

Este tópico es antiguo y puede contener información incorrecta para la nueva versión.

My speakers are making a interference noise when hooked up to vdj through maya44. I have checked it is not the speakers that are the problem. When I take out the two lines and just leave the speaker cable in it goes away. From what I have gathered it is either going to be the cables, the sound card or the mixer. I am going to buy new cables as my setup includes Kam ddx750 and Kam ksp100, both brand new so I find it hard to believe it is the mixer. I also bought the maya44 new and has had barely any use at all. Any help would be great, thank you

Hi thanks for the reply, however I have a PC very capable of running VDJ, (Intel E8400 2X 3.00ghz, 3GB RAM, 500GB HDD). I have tried changing the settings in VDJ and nothing has changed, muting the input & output on the asio config has no effect whatsoever as well. Am quite puzzled
 
Please be more descriptive on what the "interference" is... Also include what speakers you are using and how you have them hooked up, what kind of cabling, etc. ie: 1/4 inch cables or XLR mic cables. One thing that comes to mind, if the interference sounds like a faint machine running you could have a grounding issue with your laptop, a common discussion on these boards because some laptop power transformers have a grounding pin and a lot do not. Mine do so I have pulled the pin out (on my own risk of course) if you don't want the safety concern you can get a PCDI audio interface which normally come with ground lifts on the signal side, (so your laptop power supply can stay grounded for safety)
 
Regardless of your computer's specification, please check all the points mentioned on the page above.

The highest specification PC can perform worse than a cheap low specification computer if it is loaded with 'bloatware' or has buggy firmware and/or drivers that cause high latency.
 
I uploaded a video this may be more help, there is no other noise going on apart from the speaker being on here so all you here is what is coming from the speaker http://www.youtube.com/watch?v=0BVI3XHnGtI

Describing it myself I would say it is the typical noise you would think of with the word 'interferance' in mind. It is a distinctive high pitched tone that is there all the time along with shuffling of irritating sound (picture someone blowing down a microphone, what that might sound like).

They are all hooked up via RCA cables, I have grounded as well, all the cables were bought brand new a few weeks ago with only a couple of uses so far. Please note I am using a PC not a laptop.

@jpboggis, I am no PC novice, I don't have extra proccessess running in the background CPU usage is kept to the minimum it can be with only VDJ running it is not a problem with VDJ itself, even when VDJ isn't open the speaker makes this noise. I also re downloaded the asio drivers today with no difference made

 
If it's a high-pitched 'mosquito' type noise then it could be interference from the laptop's power supply.

If it's a low pitched hum or buzz, then it is a ground loop.

In both cases, a ground-loop isolator will solve the problem.
 
Pretty sure it's the mosquito noise, you said a ground loop isolator will cure it? Care to share a link on which I should get? Thanks
 
Radio Shack.

Roughly 20 bucks.

I carry one everywhere because you just never know...

I actually carry a small tackle box full of various adapters and spare cables. I can plug just about anything into any system.
 
 
I had a similar issue and once I changed the computer's power cord, my problem was solved.
