Iron Ether
Xerograph Deluxe
Owner’s Manual
The Xerograph Deluxe is a 4-pole resonant
lowpass filter, with capabilities to sweep
the cutoff frequency of the filter using the
instrument's playing dynamics, an
expression pedal, or both simultaneously.
Controls
Frequency knob:
Sets the base cutoff
frequency of the filter. When using an
expression pedal, this knob will set the
minimum frequency from which the
expression pedal will sweep (heel down
position) - the maximum frequency (toe
down position on the expression pedal) is
set by the Exp knob.
When used as an envelope filter, this sets
the base frequency from which the
dynamics will sweep up or down.
