Voltage Controlled Amplifier with Balanced Input

https://www.electronics-lab.com/project/voltage-controlled-amplifier-with-balanced-input/

  The project presented here is a Voltage Controlled Amplifier (VCA). A VCA board helps users control the audio level from a remote potentiometer. This board requires a balanced audio signal. Gain control voltage can be adjusted through potentiometer R13. The project works with a dual (±15V) power supply. Screw terminal connectors are provided for […]
