Introduction to VCAs in Pro Tools
VCA masters have been available in Pro Tools HD software for a number of years. As of Pro Tools 12.2 they are also available in the native version of Pro Tools. A VCA (Voltage Controlled Amplifier) provides a means of easily controlling a group of faders, allowing the overall level of the grouped tracks to be brought up or down whilst maintaining the relative balance of the group members and retaining the individual track automation. This video gives an overview of how to setup and use VCAs and how they differ from aux tracks.
