Serge Stereo Variable Resonance Filter

Serge Stereo VCFQ

Stereo version of the iconic Serge Variable Q Filter (VCFQ).

As the 1983 catalog stated, the VARIABLE Q VCF (VCFQ) is an excellent general-purpose VCF offering simultaneous low-pass, high-pass, band-pass outputs. The resonance (Q) of this filter is dynamically variable by manual or voltage-control. The inputs have level control so that the percussive effects of overloading the filter can be exploited.

When a pulse is applied to the Trigger input, the filter will ring, producing a damped waveform similar to that produced by striking a resonant object. The nature of this ringing is controlled by the Q and the filter frequency. Percussive effects ranging from clicks to the sound of wood blocks and bell tones can be produced and controlled. This ringing effect can be used to achieve highly controlled complex, tonal qualities.

AUX IN is mixed into into both input channels (unattenuated). Ideal to add mono signals.
