10k ohm linear taper control for single-point remote level adjustment of voltage-controlled amplifiers (VCA, by others) is designed to interface directly with three-wire, 0-to-10-volt control inputs that are typical on most voltage-controlled amplifiers. The 10k ohm potentiometer allows the amplifier’s control voltage to be set or adjusted from a single remote location. Choose control with decorator style wall plate (in various colors) or rack mount adhesive label.
