Simple >Dual< Voltage Controlled Amplifier
The 502s SIMPLE DUAL VCA MODULE module combines two separate voltage controlled amplifier circuits each with its own signal input and signal output plus modulation input.
The module has a continuous linear/exponential controller and switchable AC/DC mode (audio signals/control voltages).
The module can act as two independent mono or one stereo VCA.
These merchants probably sell this module. Huh?
