    Hello,

each of the four VCAs is equipped with a 47k input resistor (R1, R12, R23,
R34). If you increase the values of these resistors (or add a trimming
potentiometer to each resistor) the input signal is attenuated. You find the
position of the resistors in the attached picture.

Best wishes
Dieter Doepfer
