Dual/Stereo Filter Oscillator

Dual state-variable filter

dual analogue state variable filter.
based on 2164 Quad VCA chipset 12db/Oct filter cores.
full voltage control over cutoff frequency and resonance.
individual outputs for each filter response.
variable state output with manual and voltage control.
All analogue circuitry.
hi-fidelity signal chain with low noise opamps and VCAs.
Buffered inputs and outputs.
toggle switches for Combine (links the filter B frequency cutoff controls to filter A) and serial or parallel input routing.
compact 45mm Depth (with power cable attached).
low power draw: 112mA +12V / 106mA -12V / 0mA +5V.
Works for audio as well as CV.
Fast responding CV inputs accept both DC signals and AC signals into the full audio range.
cores are very stable and will give you around 5 octaves of 1V/O tracking sine wave self-oscillation.
LP, BP and HP outputs each have a different phased sine.
