The Dual Filter features two 2 pole (12dB/Oct) filters, each with output switchable between Low/Band/High-pass response and with resonance variable up to self-oscillation.
The left-hand filter features a Sub-audio range switch allowing slew and LFO oscillations, while the right-hand filter can have its phase inverted.
The filters are temperature compensated and scaled to accurately track 1V/Oct over several octaves.
