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.
