Moonmodular 517S VC High Pass / Low Pass Filter


The 517S is a one-channel version of the 517 dual-filter. As with the big brother, users can switch between high-pass and low-pass characteristics. The edge steepness is -18 dB respectively -24 dB per octave. Cutoff frequency and resonance can be adjusted by hand plus there are several CV inputs. The 517S has a rich, silky smooth sound. – A fantastic filter!


The filter topology of the 517S is based on circuits known from Oberheim’s Xpander and OB-XA. The module comes equipped with potentiometers for the cutoff frequency and resonance. Via a switch, users can choose between high-pass (-18 dB per octave) and low-pass characteristic (-24 dB per octave). There are two CV inputs for cutoff modulations. One of them features a bipolar attenuator. The resonance is equipped with one control voltage input.
