Doepfer A-130 VCA Linear
Out of stock. Contact us for more info.
The A-130 is a VCA with linear characteristic, thus primarily intended for controlling the level of CVs. It offers two signal inputs and a output with adjustable volume. amplification is set with a Gain control and two modulation inputs.
Not only control voltages can be used to "open" the VCA and to let the inputs 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 for closing the VCA. As the module has two signal inputs often you don't need a mixer before the VCA.
