GSM-209 State Variable Filter

12 dB/Octave Topology with VC Resonance

This state variable 2 pole (12 dB/Octave) filter has two signal inputs mixed at unity gain with low pass, bandpass, and high pass outputs. If the resonance control is set high enough, the filter will start to oscillate.

Three CV inputs are provided. A 1V/Octave input controls the filter cutoff frequency in conjunction with the panel frequency control. A second frequency CV input has an attenuverter control, the resulting voltage being added to or subtracted from the base cutoff frequency resulting from the panel frequency control and 1V/Oct inputs. A resonance CV control followed by an attenuverter is combined with the panel resonance control to determine the amount of resonance that will occur.

The MU version is housed in a 1MU (2.125 inch wide by 8.75 inch high) panel with DOTCOM compatible power connector.
