The Doepfer A-130-8 Octal Linear VCA is an eight VCA with linear characteristic, mix output and two group outputs (1-4 and 5-8). Each VCA consists of CV-In, Signal-In and Out and accepts audio and CVs at the signal input. Voltages and levels in the range of 0-10 volts are processed without distortion. By patching the inputs cleverly, modulations in the stereo field are also possible.
