Voltage Controlled Amplifier Synthesizer

The vca or voltage controlled amplifier.

Voltage controlled amplifier synthesizer.

All the controls on this filter can either be controlled by a knob or by an external control voltage. 99 2 12 oz 19 99 19 99.

An authentic reproduction of the circuitry from the modular 55 35 and 15 series attenuators used by the world s most famous pop rock and jazz musicians.

Now you can build your very own unique synthesizer that can fit in a standard eurorack case. The vca is nothing more than a voltage controlled volume knob. Most vca circuits do not exceed a gain ratio of 1 meaning that they attentuate rather than amplifying in many synthesizers a vca or a digital equivalent is the last functional block that a signal goes through. The word amplifier is somewhat misleading in this usage.

A vca or voltage controlled amplifier lets you use a voltage to control the amount of another signal that is allowed through to the output of the module. Signals in a synthesizer are usually described in terms of voltage alone but really any time a signal travels from an output to an input there are three. At some voltage level the entire signal is let through. It turns the volume up when you press a key and it shuts it down after you let go of the key.

The notch output is a little unique in that it has a balance control that lets you shift between all low pass and all high pass. The higher the control voltage the more signal is passed. To understand why voltage controlled amplifier is the correct and standard expansion of vca it s necessary to consider some factors that in modular synthesis we usually try to ignore.
