Electro-Harmonix Flanger Hoax Instruction Manual

FLANGER HOAX

-OPERATING INSTRUCTIONS-

Congratulations on your purchase of the Electro-Harmonix Flanger Hoax! The Flanger Hoax
is one of the most powerful modulation instruments ever designed. From shimmering static
and active phasing to frequency adjustable flanging, you will find an exciting new palette of
textures at your fingertips. The sheer number of variations available through both familiar
and advanced modulation controls will present you with the ability to creatively shade as well
as wildly animate your music in a way that really was never before possible at this price
level. Your own creativity is your only limitation.

Connect your instrument or mixer’s Effects Send Output to the Flanger Hoax’s Input jack,
and run a second cable from any or all of the three main outputs (Direct out, Blended out or
Effect out). You will learn which outputs will serve your purposes the best in different
situations. Hit the true bypass footswitch to activate, and get ready for a magically ethereal
treat.

Please take a few minutes to familiarize yourself with the Flanger Hoax controls and how
they work.

WARNING:

not use any other AC adapters. Using other AC adapters, even those made by Electro­Harmonix, could cause harm to the unit, the adapter or you. The FLANGER HOAX does not use
batteries.

The Flanger Hoax is made up of two separate phaser sections and their associated Delay
Lines. The phaser sections are the Fixed Phaser and Swept Phaser. The Fixed Phaser will
shift the phase of your input signal by a set amount of 240o. The Swept Phaser is more like
a traditional phaser, modulated by a low frequency sine wave called the Modulator. Each
phaser circuit is followed by its own analog delay line, each of which can also be
independently swept by the Modulator. Each phaser section can be bypassed to access the
delay lines without any phase shift. To top it all off, there is a Feedback control that allows
you to send the wet output of the pedal or the output of the Swept Phaser back into the
phaser circuits.

Use only the 18VDC/500mA AC adapter supplied with the FLANGER HOAX. Do

- BACKGROUND-

- CONTROLS -

1. BLEND Knob: Mixes between the effect and the dry signal. The counter-clockwise position
is all dry, while the clockwise position is all effect. The result of the BLEND Control goes out
the BLENDED OUTPUT Jack.

2. FEEDBACK CONTROLS:

FEEDBACK Knob: Sets the amount of signal that is fed back into both phase shift circuits.
The counter-clockwise position gives you no feedback; the clockwise position yields
maximum feedback.

WET Toggle Switch Position: In the WET position, the wet signal (which is at the EFFECT
OUTPUT Jack) is fed back to the phaser circuits.

OFF Toggle Switch Position: All feedback is turned off, no matter where the FEEDBACK knob
is set.

SWPT Toggle Switch Position: In the SWPT Position, the output of the Swept Phaser is fed
back into the Phaser circuits.

3. SWEPT PHASER CONTROL:
AMOUNT Knob: Controls the amount of modulation that sweeps the Swept Phaser. In the
counter-clockwise position, there will be no modulation. In the clockwise position you will
have maximum modulation. The total phase shift range of the Swept Phaser is 240o to 990o.

RESPONSE Rotary Switch: Determines how the Swept Phaser reacts to the modulation
waveform. In LIN Mode, the Phaser reacts in a linear fashion, in LOG mode, it reacts in a
logarithmic fashion. In the LOG mode, the Swept Phaser tends to sound more exaggerated.

MODULATOR MODE Rotary Switch: This switch steps through the different phases of the
modulation waveform. When used in tandem with Delay modulation, interesting effects arise
when the Swept Phaser modulation is in or out of phase with the Delay modulation. The
rightmost position of this switch is DC Mode, in which the Swept Phaser becomes a fixed
phaser and the amount of phase shift is controlled with the AMOUNT Knob.

4. MODULATOR

RATE Knob: Sets the frequency of the sine wave Modulator. The available frequency range is
from 0.07 Hz (14 Seconds) to 220 Hz.

DELAY MODE Switch: Selects between different phase shift combinations for the modulating
waveform that sweeps the Fixed Phaser Delay line and the Swept Phaser Delay line:

Fixed Phaser Delay Swept Phaser Delay
Mode 1: 0o Phase Shift 180o Phase Shift
Mode 2: DC 180o Phase Shift
Mode 3: 0o Phase Shift DC
Mode 4: 90o Phase Shift 180o Phase Shift
Mode 5: DC DC

In DC Mode, the delay time is set by the Delay Amount knobs, described in the following
section.

5. FIXED and SWEPT PHASER Sections: The Flanger Hoax has two independent phase shifter
circuits: a FIXED Phaser and SWEPT Phaser. The FIXED Phaser is set to a phase shift of
240o. The SWEPT Phaser varies from 240o to 990o. These two phase shift sections run
parallel to each other. The output of each phase shifter goes into its own Delay line circuit.
The FIXED and SWEPT Phaser blocks on the right side of the Flanger Hoax have similar
controls, though the SWEPT PHASER has additional controls in the SWEPT PHASER
CONTROL Block:

DELAY AMOUNT: Controls the amplitude of the sine wave that modulates the delay time or
when set to DC mode, sets the delay time. The DELAY MODE Switch in the MODULATOR
section chooses between waveform modulation or DC (see the chart above). The range of
delay time is 1 ms to 11 ms.

FIXED/BYPASS Toggle Switch: Either bypasses the FIXED Phaser circuit or enables it. When
in Bypass, the audio signal will go around the FIXED Phaser circuit and then into its Delay
line. When in Fixed mode, the audio signal goes through the FIXED Phaser and then into its
Delay line.

SWEPT/BYPASS Toggle Switch: Either bypasses the SWEPT Phaser circuit or enables it.
When in Bypass, the audio signal will go around the SWEPT Phaser circuit and then into its
Delay line. When in Fixed mode, the audio signal goes through the SWEPT Phaser and then
into its Delay line.

INVERT Toggle Switch: This switch inverts the output of the FIXED Phaser block after its
Delay line circuitry. By enabling the INVERT Switch , you add 180o more phase shift to the
FIXED Phaser output. The SWEPT Phaser does not have an invert switch.

All Electro-Harmonix accessories are compatible and modular. Any combination of units will
give you an infinite variety of sounds limited only by your imagination.
