Voltage Controlled Amplifier – VCA

https://www.electronics-lab.com/project/voltage-controlled-amplifier-vca/

The project presented here is a Voltage Controlled Amplifier (VCA). A VCA board helps users control the Audio Level from a remote potentiometer. It requires a single-ended audio signal in the input. Gain control voltage can be adjusted through an on-board potentiometer or use an external potentiometer connected to CN4. The project works with a […]
