One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...
A simple linear voltage-controlled amplifier can be constructed with one op amp and two JFETs (see the figure). The amplifier can achieve an 80-dB dynamic control ...
VCA grouping is a powerful feature that can be just what you need when you’re mixing, but what are its benefits and how do we use it? That’s what we’ll be tackling in this masterclass today. We ...
