The VCAs of the A-134-4 are DC coupled. CV2 of VCA1 should behave like CV1
with the trimming potentiometer for CV1 in it's max. position (i.e. no
attenuation) or like the CV2 of the other VCAs. If that's not true please
return the module for service to the dealer where you purchased the unit.
Which CV is used to control the A-134-4 ? As CV1 of VCA1 is normalled to the
other CV1 inputs the load is 4 times more than for the other inputs. Each
load is 220k or ~ 55k for CV1 of VCA1. Normally such a load should cause no
problems unless a control voltage source with high impedance output is used.
