DoepferA-101-1V Vactrol Steiner Filter (Vintage Edition)

Doepfer A-101-1v

Module A-101v is a vactrol-based multimode filter with a couple of tricks up its sleeve. For one, its three inputs each correspond to a different part of the filter circuit, giving users access to separate LP, BP, and HP inputs. Separate signals can be fed into the inputs, or a single signal can be multed into all three for a wide variety of possible sounds. There are also two outputs, one with resonance-based level control, and another with an additional vactrol capable of behaving like an attenuator or pseudo VCA to compensate for increased levels at higher resonance settings.
