Take four channels and send their signal to one fader. Every time you increase the volume of that group fader, the group control sends a message back to those channels so each channel increases the volume coming out of it. A VCA is more like a remote control. And if thatâs not enough, letâs add in the DCA. The DCA (digital-controlled amplifier) works much like it sounds; instead of altering the actual signals from the channels, they are processed in the same way which then leads to increased or decreased volume.
