1u dual vca


The 1u dual vca is 6hp in width, it has two channels each forming a row with a signal input, control voltage input, and signal output jack appearing from left to right on the front panel. Built around the AS3360D IC, the signal input maximum is 20Vpp, the signal output maximum is 10Vpp, depending on the resistor configuration each vca will become fully open according to the following table:

	vca 1	vca 2
5V	R7 = 30k, R8 = 24k	R12 = 30k, R11 = 24k
8V	R7 = 100k, R8 = 47k	R12 = 100k, R11 = 47k
10V	R7 = 47k, R8 = 47k	R12 = 47k, R11 = 47k
