Xerograph Deluxe by Iron Ether

The Xerograph Deluxe by Iron Ether is a 4-pole resonant lowpass filter pedal designed for creating classic, modern, and unique sounds. It features low- noise, low-distortion active components chosen for excellent audio fidelity. The pedal measures 4.7" and runs on an industry-standard 9-volt DC center- negative power supply with a 150mA current draw. It is equipped with a relay- based true bypass system for quiet switching and greater reliability.

Key features and controls include:
- Frequency knob: Sets the base cutoff frequency of the filter and can be used with an expression pedal to sweep the cutoff frequency.
- S/F switch: Selects slow or fast envelopes.
- 2/4 switch: Selects between 2-pole and 4-pole modes, offering different resonance characteristics.
- Resonance knob: Adds feedback around the filter, boosting a narrow band of frequencies around the cutoff.
- Filter Vol: Controls the output volume of the filter signal.
- Clean Vol: Controls the volume of the unfiltered signal, mixed in with the filter.
- Sensitivity knob: Controls how much the playing dynamics will sweep the filter cutoff.
- Up/Down switch: Controls the direction of sweep for the envelope follower.

The Xerograph Deluxe allows the cutoff of the filter to be modulated by three separate sources: the Frequency knob, input dynamics, and the expression pedal, providing a wide range of sound sculpting capabilities. The pedal is designed to be used with the Moog EP-3 expression pedal, which is wired to correctly interface with the Xerograph Deluxe and has a range attenuator knob for setting the range of the sweep.

The pedal is warranted for materials and manufacturing for one year from the date of purchase and features a unique, individually machine-engraved and hand-painted finish. It is recommended to use it with other Iron Ether pedals such as the Oxide, Subterranea, QF2, and FrantaBit for different varieties of harmonic richness.
