SYNTHROTEK DIRT FILTER

Description

DIRT is our new 4HP low-pass filter / effect for the Eurorack modular synth platform. Inspired by one of our favorite ‘noisy’ filters, the DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob, accessible from the front panel.   It’s not a traditional filter; it’s an effects module with filtering, ring mod effects, wave shaping and even outright brutal harmonic distortion. DIRT likes to square things up a bit, so throw in a triangle, sawtooth, sine or other wave forms for different style effects.  Even plugging a guitar (using an external amplification module) into the DIRT produces some great sounds and heavy distortion. Controls: – CUTOFF = Cutoff Frequency – RESONANCE = Increase the Q! – BIAS = Set the bias correctly or not, the choice is yours  Inputs/Outputs: – CUTOFF CV IN = Voltage range changes depending on where CUTOFF knob is positioned. External attenuation will be needed for fine modulation. – AUDIO IN = Audio Input – AUDIO OUT = Audio Output  Other info:  – PCB Dimensions: 4 x 1.5 inches – CV input impedance is 47K – 4HP – Power consumption:>1mA
