Adjusting Infinity IRS servo controller

I got a request from @bobterry99 about adjusting Infinity servo controllers.  Inside the controller are 4 pots:

Left side level (amplitude)

Left side DC offset

Right side level (amplitude)

Right side DC offset

See the attached photo.  I used a 2 ch oscilloscope to monitor the input and output while adjusting.  With 4 ch, you could monitor both channels...

Which version of the servo and which speakers?

BTW, I am looking for a reputable shop to go over my spare servo controller (IRS Beta) to make sure its all up to design specs

Multimeter I have! (and the plastic "screwdrivers")

Could you share insights on how to measure and set levels?

I have the same situation, I have my LF Gain at -10 to have a good balance between LF and Mid/Hi Frequencies
