I don’t have an accurate RMS meter, but I do have a very good digital meter and checking at 200Hz my own test PPM and the 2 meters in my own 828S, sit nicely at ‘4’ when the sine wave input reads 0.775V AC.
The preset that is closest to the input terminals is the overall gain adjust. The others adjust the various break points….. and setting it up is a lengthy process that I don’t have a note of to hand
