OMNITRONIC EDP-1000 adjustments?

Hello,

I'm repairing a pair of blown-up EDP-1000 OMNI's. There is a variable resistor VR1 on the daughter-board of the Class-D power amp stage, which I'm not sure how to adjust. On the schematic is says "PWM DIV (...) AV=9.68/2.4K", no test points or adjusting procedure provided. You will find the schematic of the daughter-board in the EDP-700 pdf file, in the EDP-1000 is missing, but is the same.

Thank you very much.

Boris.
