2-pole mode is a classic, funky filter with a wide, vocal-like resonance peak.
4-pole mode offers a fat, deep, and synthy filter with a sharp resonance peak.
Frequency: When using the filter without an expression pedal, this control sets the cutoff frequency of the filter, allowing you to dial in deep, dubby bass sounds. When using an expression pedal with the Xerograph, the Frequency knob sets the low extent of the filter sweep.
Resonance: Boosts frequencies around the cutoff frequency, which intensifies the effect of the filter. Set the resonance low for more subtle tone-shaping, or turn it up to around 3-o’clock for wet synth sound. Turning it to maximum sends the filter into self-oscillation.
Volume knob: Sets the output volume of the effect, ranging from quieter than the bypassed signal, to boosted.
Frequency expression jack: Connecting a passive expression pedal to the expression jack allows you to control the frequency of the filter with your feet, allowing for slow, resonant sweeps, or fast, funky squelches.
Low-noise, low-distortion active components chosen for excellent audio fidelity.
