Description
Voltage Controlled Amplifier A VCA, or Voltage Controlled Amplifier, is an amplifier that varies its gain depending on a control voltage. In a mixer this applies to signal routing and channel strips. The purpose of a VCA is to allow you to turn up or down a group of faders while maintaining the relative levels throughout the group.

A Brief On The Use Of VCA Masters in a Pro Tools HD session

I borrowed this from the DUC. I hope it makes more sense than I do at explaining things. YMMV as does each DAW. I do NOT mean this as a directive to send anyone towards Pro Tools as a choice of their DAW. Since this method was taught to me it has opened up my mixes and made my work flow somewhat easier with drastic results.

VCA (Voltage Controlled Amplifiers) Samplitude

The VCA fader in Samplitude Pro X2, whose usability and comfort is based on large analog mixing consoles, is natively integrated in the DAW. The VCA fader allows you to control all relevant levels when mixing your project. Each existing channel strip can be easily turned into a VCA fader. You can also assign individual channels to a VCA group and control them using the VCA fader in the mixer.
