The Philter's core is a two-pole design with 12dB slope and a special resonance limiter ofr high peaks without oscillation. There are simultaneous outputs for low-pass, band-pass and high-pass with LEDs displaying signal level at each filter type.
The cutoff frequency and resonance are dialed in with potentiometers and in addition there's a FM input with attenuator for modulating the cutoff.
