Mpc 500 high pitched noise recording problem.

When recording my MPC with both a Trackmaster Pro preamp and my VS-100 I get a high pitched noise. Does anyone else have this problem?

I almost think it's the MPC because when I have headphones plugged in I can hear is very very faintly. When recording it is more prominent.

turn off backlight on 500
Run all gear off one outlet of your room-pre could be groundlooping

I get a funny high pitched little whine when resampling internally.
Its weird because it doesn't do it at first, but than after taking a sample or two it pops up and I can make it go away by backing out of the sampling menu and then going back into it.

Maybe its that grounding.

Grounding has to do with the electric circuitry and the enviroment the 500 is in. Input and Output jacks should never touch each other nor should they be crossing the AC cable which can cause such feedback. Remember that for all your equipment.

This is my biggest issue with MPC 500!
Recording Mode: No matter what setting the noise is always there when you record to MPC 500.

Power Plug & 1/4 jacks are spread apart from each other Batteries without Batteries same result.
Lower Master Level, Normalize, all fx off, still this annoying noise over everything I sample with!
When you record into MPC 500 there is audible noise with LED "on" its worse.

You can even hear if you go to MODE + Record you'll hear the mid & hi freq.
I lowered the Master Level to -24 although you cant hear the noise much but after recording it more audible!

WTF!
What kind of sampler cant sample correctly?!!?!

i too have this problem once in a while but it seems to be more random here. Also i once picked up asian talk radio through my 500 + dj mixer.
