Product description
The A-131 is a VCA with a exponential characteristic and is intended for controlling the level of audio signals by voltages. Improved version since 2013
Not only control voltages can be used to "open" the VCA and to let the audio pass through, there is also a manual gain control. This is pretty handy when you want to modulate the VCA with a bi-polar voltage - just turn up the gain haf-way - this way you can use the CV's negative signal parts to close the VCA.
As the module has two signal inputs often you don't need a mixer before the VCA.
