Fairfield Circuitry Roger That

Roger That Inspired by Roger Grant's idea to mimic loss of fm radio signal through the use of a simplified fm modulator/demodulator scheme. As a young child, I would hide under the table when Roger came around. Later, when I first started in electronics, he gave me a bunch of parts, tools and bench equipment. Controls interfere with demodulation accuracy resulting in familiar yet unexpected signal degradation and noise. Decoherence at its finest. Controls: TUNE: Like turning the dial on your receiver, the TUNE parameter sweeps through a wide variety of sounds. From subtle artifacts, to extreme textures, noise and distortion. Summmed with CV at T input. SHIFT: Shifts the accuracy of tracking the incoming modulated signal. Sometimes acts as a filter. Highly dependent on TUNE. DRIVE: Controls the input level, from clean to dirty. Pushing the DRIVE control generates extreme non-linearities from the modulator/demodulator circuit. Affects both the wet and dry signals. WET: Amount of wet signal at the output. DRY: Amount of dry signal at the output. R: Preset range of the TUNE parameter: 1 - normal 2 - extended F: Apply voice filter ~(300Hz-3kHz) to wet signal: 0 - filter off 1 - filter on CONNECTIONS: IN: 1/4" Instrument input OUT: 1/4" Output T:1/8" CV input for TUNE 9V: 2.1mm 9VDC centre-negative tip, >30 mA NOTES ON INTERACTIVITY: -The TUNE, SHIFT, DRIVE and RANGE controls are highly interactive. -The higher the DRIVE, the more artifacts will be generated. -TUNE is probably the widest, most non-linear, finest control ever included in our products. Micro adjustments here will drastically change the result of the demodulation. -TUNE and SHIFT are mutually dependant, almost like they are the same control. By tweaking both, it almost seems like there is endless varieties of sounds. -The RANGE switch shifts the whole palette of possibilities. -Wet signal path is intentionally out of phase allowing for special interactivity between WET, DRY and FILTER. -If the original signal is still present on the wet side, adding dry signal will cancel it out leaving only the distortionartifacts. -If voice filter is activated in these same conditions, the result is a kind of mid-scoop instead of the usual bandpass. FEATURES AND USES: -JFET pre-amp -CV on TUNE -RFI/EMI approximator -FM/AM radio quality reducer -volatile and unpredictable distortion •noise, pop, crackle and squeal generator -impress your friends TECHNICALS: -true bypass -dimensions 4.7" x 3.8" x 1.9" -input impedance 1MΩ -output impedance 1kΩ Needs: 9VDC 50mA Center Negative
