Issue with uneven recording level from Audio. Please help

Hi. The recording level on my 2500 has suddenly gone completely uneven from Left and Right when recording audio outut through my mixer. The left side is peaking through the roof and the right side is only about half that level. I tried different cables and a different mixer to isolate the problem, and it is the MPC itself.

Has anyone had a similar problem and know a solution as the machine is a few years old and no longer in warranty.

Thanks. BX

It might be that your panning position need to be normalize.
