DESCRIPTION


VCF-A LOW PASS

The VCF-A LOW PASS Filter attenuates frequencies above the cutoff point at a rate of 24dB per octave.

The Frequency Range Knob sets the frequency band over which the LP CUTOFF Knob operates:
Range I: 1Hz to 5kHz
Range II: 4Hz to 20kHz
Range III: 16Hz to 80kHz

The Regeneration Knobc controls the amplitude of the signal at the CUTOFF frequency. As resonance increases, the harmonics around the cutoff frequency appear louder and more pronounced than in the original signal. At very high settings, the filter goes into self-oscillation, producing a wave on its own. The frequency of this wave is set by the CUTOFF control.


VCF-B HIGH PASS

The VCF-B HIGH PASS Filter attenuates frequencies below the cutoff point at a rate of 24dB per octave.

The Frequency Range Knob sets the frequency band over which the HP CUTOFF Knob operates:
LOW: 4Hz to 20kHz
HIGH: 10Hz to 50kHz


VCF-C COUPLER

The VCF-C COUPLER combines the functions of the VCF-A LOW PASS and the VCF-B HIGH PASS filters together.

In 'OFF' position the filters are disconnected, similar to a bypass switch.

When switched to the 'BANDPASS' mode, Highpass and Lowpass filters are coupled in parallel to process a central band of frequencies - deleting both buttom and top.

The 'BANDREJECT' mode presents the inverse relationship, rejecting a central frequency band and passing only the lowest and highest frequency components.

Hello Brice, VCF-A is a LowPass Filter, VCF-B is a HighPass Filter and VCF-C is either, i)bypassed, ii)BandPass, or iii)Notch. These can be combined in any way you wish; ie. in parallel, series, or a mixture of those. Given the steep falloff of 24dB per 8ve, using them in parallel helps retain some of the original signal, where filters are cutting.

Can someone shed some light on the best way to wire these together? In series with the VCF-C at the end?

These sound great! Clean masking, with gentle squeal and boom. Thanks!
