Schlappi Engineering Angle Grinder – Silver

Angle Grinder from Schlappi is an 18hp quadrature sine wave oscillator, filter, and distortion.

• Quadrature Sine wave VCO with four phase related outputs: 0, 90, 180, 270
• HIGH range from 10Hz to over 20kHz
• LOW range from 0.3Hz to over 500Hz
• Tracks 4+ octaves of volts per octave at the V/OCT input
• FM1 is selectable linear or exponential FM via jumper on back
• FM2 is additional exponential V/OCT jack
• With no input GRIND section provides voltage controlled harmonic content
• With input GRIND section compares each phase against GRIND IN signal
• Each slider subtracts the compared signal from the input signal, creating complex waveshapes
• When GRIND is fed into the SPIN section the outputs become a state variable filter
• DAMPING counteracts the oscillation and allows an external signal through
• When filtering the four phase related outputs are: LOW PASS, BAND PASS, HI
