Schlappi Engineering Angle Grinder Black, Eurorack Module, Quadrature sine oscillator with filter and waveshaper, SPIN section: Quadrature sine wave oscillator with 4 outputs (0°, 90°, 180°, 270°) and tracking over 4 octaves, GRIND section: Compares the SPIN outputs with an input signal and derives square wave signals which are fed into a VCA and modulated by the 4 GRIND CV inputs and GRIND fader, Depending on the setting, the module functions as an oscillator or state variable filter, Controls for coarse and fine tuning, attenuation, GRIND/SPIN ratio, FM input with attenuator (linear or exponential), GRIND input with attenuator, 4 SPIN outputs provide phase-shifted sinusoidal signals or in filter mode low-pass, band-pass, high-pass and notch characteristics, Current consumption: 81 mA (+12 V) / 78 mA (-12 V), Width: 18 TE, Depth: 25 mm, Colour: Black
