Sputnik Modular Quad VCF/VCA

Description

The Sputnik Quad VCF/VCA is a four channel, vactrol-based "lo-pass" gate with four independent outputs, a mix output, and two sub-mix outputs. Each of the four channels has a selectable switch for VCF, COMBO, and VCA modes. In VCF mode that channel will act as a non-resonant -6db low pass filter with the cutoff frequency controlled by the control knob and by a unipolar CV input. Switching the channel to VCA mode will allow for control of the amplitude of the input signal (gain varies from -120db to +3dB).Switching to COMBO mode allows for simultaneous control of amplitude and timbre by the CV input or by the control knob.Outputs include individual channel signal outs, an ALL output (all outputs summed for mixing), an ODD out (outputs 1 and 3 summed) and an EVEN out (outputs 2 and 4 summed).
