Title: Main VCA subgroup Fader balancing/adjustment
Post by: Mattsepanic on December 26, 2023, 11:47:29 PM

One of my 8 main VCA subgroups is metering lower than the others.  My assumption was there would be fine adjustment on the  82e20 card for each of those subgroups.  Like on the individual channel strips VCA card - But Im not seeing any variable resistors  on the schematic for the 8220 card, although our manual isn’t the original so some things don’t match exactly . I had to leave before I could get the center section up.  Any help or suggestions on getting those evened out would be greatly appreciated - TIA

How much lower? 1 dB or 10 dB?
