This is a recreation of the classic ARP 4072 Voltage Controlled Filter by Yusynth. The 4072 filter was used in the ARP 260 semi-modular synthesizer.
Yves has modified this version of the filter to include input and output buffer stages. The output buffer helps to compensate for the loss of low frequencies that is generally observed at high resonance.
The filter supports 2 Signal Inputs each with its own attenuator for mixing.
2 Control Voltage Inputs are available for modifying the Cutoff Frequency.
The ARP 4072 VCF comes in a 2U width with 1″ (25.4mm) knobs controlling 4 potentiometers; Input and CV Levels and Emphasis. 1 30mm knob controls the Cutoff Frequency potentiometer.
The module operates at +/- 15V and comes with a Synthesizers.com style power connector.
