Does anybody knows??

Hello community, It has been a while that I didn't came here, but damn, I came with a damn issue im tryin to solve 2 month's ago.

Main issue: anoying oscillating noises constantly while power cable is connected to mpc and electricity.

I have an MPC 2500 SE connected to my external audio device (it doesnt matter but it is a x-station 25), I've already tried all kind of stuff, since connect my headphones directly to "phones" in on mpc. But the problem is not on my soundcard, or monitors, or even other stuff.... The problem, I FOUND, is in the damn electricity? Now it goes beyound my knowledge. EVERYTIME I plug the mpc to electricity (through 10A 250V~) noise will start instantly, its so anoying, so anoying. I CANT GET RID OF IT. I tried every plug in my house, with different cables and ****. Please someone help me on this. I CANT PRODUCE BEATS ON MY MPC. Its frustrating me a lot.

PEACE.

(When I connect my headphones to my MPC I cant hear any noises, but while Im hearing through my external audio device the noises are frequently there, like oscillating wind.)

oh, thanks Lampdog.

I was trying to make an example, maybe its gonna be easier for people to help me.

Just pay attention to the background noise. After I unplug power cable of mpc the noise goes off totally.

Let me know...

(just notice the background anoying noise, try to identify it.)

Get a Furman Power conditioner. It regulates voltages and protects your gear among other things. Every producer should have one to protect their gear. They also help with side noise issues. I use a PL-Plus c

Is it that you get the hum when the MPC is plugged in but not connected with audio cable. Or is it only occurring once you start to plug in the MPC audio outputs to other equipment?

If its the first one then that's one crazy induction problem, would put that down to a seriously faulty transformer perhaps, or like Lampdog says, maybe a dodgy earth/grounding in your house. If its the second then its a simple ground loop problem (see above links).

But as saxplaya81 suggests, power conditioners are good to use anyway even if you are not getting these problems. I use a basic Mains Filter, I've had it so long I even forget I'm using it.
