Voltage Controlled Amplifier. A circuit whose gain is determined by a control voltage.
Voltage controlled amplifier. A circuit design that allows remote control of a signal. Typically used in high-end groupings on mixers. A VCA group is one where the group fader sends a signal to the individual channels assigned to it to adjust their levels in the individual channels as compared to sending their signals to the soub-group to control. see subgroup
Acronym: oltage ontrolled mplifier Electronics: component that provides a level of amplification determined by the voltage on a control input, so that changing the voltage changes the amplification.
