Slew-Limiting Distortion with Attitude - The Fairfield Circuity 20% More Slew Limiting Distortion Effects Pedal Explorations around a schematic found among old papers of mysterious origin, suspiciously similar to a datasheet sq/tri oscillator. All that was needed was to connect the dots. A slew limiter smoothes out how quickly incoming voltage can change, limiting it to a fixed v/sec. slope. Since time and frequency are intrinsically linked, this acts as a steep, somewhat distorted low pass filter. When it resonates, these fixed slopes become triangle wave oscillations, giving 20% more its unique sound. Input signals can overwhelm this oscillation, making for pseudo-wavefolding and synthetic distortion artifacts. jfet clipping, sub and upper octaves, envelope follower, low pass gate; impressions, ideas, pleasures and pains SPECIFICATIONS Controls INPUT – 'mu amp' JFET preamp, lots of gain BLEND – mixes in a square wave / sub-octave copy of the signal VOLUME – output volume, gets very loud SLEW – slew limiter frequency FEED – slew limiter feedback LPG – low pass filter D - OCTAVE DOWN – clock division of the blended square wave, -1 or -2 oct U - OCTAVE UP – analog octave up, full wave rectifier E - ENVELOPE DESTINATION – routing of the internal envelope, either added to the (L)PG or (F)EED controls Connections IN – 1/4" instrument or line input OUT – 1/4" output CV – versatile 1/4" TRS CV/Exp port, see programming guide S – 1/8" input CV over slew limiter frequency, v/oct 9VDC – 2.1mm centre negative tip, 20 mA (sags quite well) Dimnesions Dimensions – 4.7" x 3.8" x 1.9" CV Input Range – 0 - 5V normal; 0 - 8V max Power Supply – 9VDC Current Draw – 20 mA @ 9.6 VDC Manufacturer: Fairfield Circuitry MAS Distro Model: FC-20M SKU: I827222-N-1-WHXE We are Chuck Levin's Washington Music Center Since 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Wa
