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

Resonance knob: Adds feedback around
the filter, boosting a narrow band of
frequencies around the cutoff, intensif ing
the effect of the filter. Set this low for
more subtle tone-shaping effects, to the
center for "quack " sounds, or up to
around 3 o'clock for a wet s nth sound.
Turning the knob to maximum sends the
filter into self-oscillation.
Filter Vol knob: Controls the output
volume of the filtered signal.
Clean Vol knob: Controls the volume of
the unfiltered signal, mixed in with the
filter.
Sensitivit knob: Controls how much the
pla ing d namics will sweep the filter
cutoff; all the wa counter-clockwise will
turn the envelope follower off completel ,
so the filter is controlled onl b the Freq
knob and expression pedal.
Exp knob: Sets the maximum frequenc
to which the connected expression pedal
can sweep.

Env stomp switch: Turns the envelope
follower off (LED lit blue) or on (LED lit
turquoise). When off (blue), the filter's
frequenc will not respond to our pla ing
d namics, which can be useful as a static
filter or for sweeping with the expression
pedal.
Up/Down switch: Controls the direction of
sweep for the envelope follower. In Up
mode, the filter frequenc starts at a low
point selected b the Frequenc knob, and
sweeps higher with increasing d namics.
In Down mode, this is reversed - the
Frequenc knob selects the highest
frequenc and sweeps down from this
point.
S/F switch: Selects slow or fast envelopes.
2/4 switch: Selects between 2-pole and 4-
pole modes. 2-pole is a more mellow,
classic sounding filter with a wide, vocal-
like resonance peak. 4-pole mode is more
s nth-like, with a steeper cutoff and a
sharper resonance peak.

Range and interactivit
The Xerograph Deluxe is designed to be a
powerful, versatile tool for creating classic,
modern, and unique sounds. The controls
have a wider range than is commonl
found in effects pedals, so that the user is
not limited to a small subset of possible
sounds and techniques. At first this range
can be trick to harness, and it's quite
possible to set the pedal in a wa that
filters out all audible frequencies and lets
no sound through at all, but with use
these controls should become quite
intuitive, and the increased range will be
useful in sculpting unique new sounds.
In the Xerograph Deluxe, the cutoff of the
filter can be modulated b three separate
sources - the Freq knob, the input
d namics, and the expression pedal. Since
these are all mixed together to control the
cutoff, b necessit the will interact with
each other.

Quick start/a tour of sounds
Start with all switches to the right, and all
knobs down all the wa (counter-
clockwise). Turn up the filter volume
halfwa , and begin turning up the
Frequenc knob slowl while pla ing. You
will hear frequencies graduall becoming
audible, from low to high.
Leaving Freq at about 9 o'clock, begin
turning up Sensitivit so that ou can hear
the filter sweep up and down with each
note plucked on our instrument. Leave
Sens at a spot that gives a medium sweep
with our instrument's volume level, and
begin turning up Resonance. You will hear
how this emphasizes certain frequencies
and makes the sound more s nth or
"funk ."
Switch S/F to slow mode and get a feel for
how this reacts to our pla ing. The
amplitudes of multiple notes in quick
succession will be averaged out, so that
instead of sweeping up and down with
ever note, the filter can be smoothl
pla ed up and down b pla ing notes

closer together or more sparsel .
Switch to Down mode - in this mode ou'll
generall want to turn Freq much higher
than it would be in up mode, and ou ma
want a higher Sensitivit setting in this
mode as well since we want to sweep far
down from the maximum.
Use with other pedals
The XD is great for carving up and
accentuating harmonics. Feeding it a
signal with plent of harmonic complexit
will give it much more material to work
with, and lead to stronger sounds. Iron
Ether pedals such as the FMeron, Oxide,
Subterranea, QF2, and FrantaBit are all
designed to add different varieties of
harmonic richness and therefore work well
preceding the XD. Tr our favorite fuzzes
and overdrives in front of it. Note that the
output level of the pedal(s) preceding the
XD will impact the wa the envelope
follower responds.

Expression pedals
The Moog EP-3 is recommended to
control Iron Ether pedals. Other
expression pedals with a resistance
between 10k to 50k will work, if the are
wire with wiper to tip.
B pass
The XD features a rela -based true b pass
s stem. When the pedal is b passed, the
signal is connected directl from the input
jack to the output jack via a mechanical
switch, and does not pass through an
buffers, electronic (FET) switching, or
other circuitr that could have an effect on
sound fidelit . It's different from the more
common true b pass in that instead of a
3PDT stomp switch, the XD uses a
mechanical rela designed specificall for
low-voltage audio-t pe signals. This makes
for a quieter switch, greater reliabilit , and
the bonus of automaticall going into
b pass if power to the pedal is lost.

Power suppl
The XD is powered b the industr -
standard 9 volt DC center-negative power
suppl (2.1mm jack). It draws 85 mA of
current. Use a power suppl that can
source at least this much current.
Warrant
Your Xerograph Deluxe is warranted for
materials and manufacturing for one ear
from the date of purchase. The warrant is
void if ou use the wrong t pe of power
suppl , take it apart, attempt to modif it,
or use it in a wa not intended.
