Intellijel uVCF (used)

State-variable multimoder filter

State-variable multimoder filter that is very suitable for small portable systems because of it´s small width of 6HP only. The filter tracks well more than four octaves and generates a clean sine wave at self oscillation so you can use the module quite well as a sinewave oscillator.
A very clean and precise, resonant, state-variable type multimode filter with three simultaneous filter types: a 12dB/octave lowpass, a 12dB/octave highpass and a 6dB bandpass.

Two inputs for controlling cutoff frewquency are available: FM1 with attenuator and FM2 with polarizer. With the FM1 attenuator fully opened the filter will track exactly 1V/octave for more than four octaves.

The resonance reaches self oscillation and you get very low distortion sinewaves with a range of 2Hz to 20Khz. In combination with the good tracking you can use the uVCF module very well as a sinewave oscillator
