somethings wrong with stereo out on my MPC !

Hi everybody ! (sorry about my bad english, but im danish an only 14 years old)

When i turn on my mpc and mixer there come a constant sound there goes like "Broooooommmhh". My mpc still works but there's just this sound, what can there be wrong with my stereo out ? and how can i stop the sound .

Jahl , holla !

I have my mpc hooked up to my dj mixer. The rec outs of my mixer go into the inputs of my mpc and the mpc outputs go into my session mix of my mixer.

I only get something you describe when I go to the sample menu on my mpc and forget to turn down my session mix on my mixer. It isn't so much of a I "Broooooommmhh" sound but rather a "EEEEEEEEEEeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeerrrrrrrrr" sound

Yea its that "eeeeerh" sound sorry .
- but its something with my mpc, because if i connect my headphones to my MPC then the sound still there.
Sombody who know what it can be ?

Have you tried unplugging your mixer? Also do you have any power cords, like the mpc's, that's running across any of your audio outs?

Sounds like you are getting feedback. If the mixer is connected to the MPC and then the outputs to the mixer and your gain is up you are creating a loop in signal flow. Bring your REC gain down before you go into Sample mode and adjust accordingly. Hope that helps
