The Quad VCA contains four identical amplifiers. Each instance comes equipped with signal input, level potentiometer, boost switch (6 dB) and an output. Additionally, there is a knob for continuously adjusting the response curve from linear to exponential characteristic per channel. This means, that the circuits are perfectly suited for processing audio material as well as control voltages. CV inputs with attenuators allow the user to modulate the level of each VCA. Each control voltage socket is normalled to the adjacent one for cascaded control. The signal outputs are interconnected in the same fashion. This makes it possible to mix incoming signals.
