1 Introduction
Welcome!
Thank you for making the Alesis AcoustiFX a part of your setup. Since 1984,
we’ve been designing and building creative tools for the audio community. We
believe in our products, because we’ve heard the results that creative people like
you have achieved with them. One of Alesis’ goals is to make high-quality music
equipment available to everyone, and this user manual is an important part of that.
After all, there’s no point in making equipment with all kinds of capabilities if no
one explains how to use them. So, we try to write our manuals as carefully as we
build our products.
The goal of this manual is to get you the information you need as quickly as
possible, with a minimum of hassle. We hope we’ve achieved that. If not, please
drop us an email and give us your suggestions on how we could improve future
editions of this manual.
We hope your investment will bring you many years of creative enjoyment and
help you achieve your musical goals.
Sincerely,
The people of Alesis

Introduction
About the AcoustiFX
The first thing you’ll probably notice about the AcoustiFX is
its size—it’s not much larger or smaller than most other
effect pedals. But don’t let that fool you. The AcoustiFX does
much more than most pedals you’ll find on the market today
(and for an unbeatable price too). We’ve packed a lot of
effects and other features into this unit. Here’s a glimpse:
AcoustiFX Key Features
•
Audio processing that’s made specifically for mic’d
acoustic guitars and other acoustic instruments (sounds
great with acoustic/electrics too)
•
40 preset patches that you can fully edit, store and
restore to the factory default settings
•
8 effect modules that provide multiple selectable effects
•
More than 40 different effects with adjustable
parameters and numerous effect combinations
•
Built-in auto-chromatic tuner
•
Battery-powered operation and an external power
option (9VDC)
•
Simple interface that gives you quick and easy access to
the AcoustiFX’s features
AcoustiFX Basics
Benefits of a Multi-Effects Pedal
If you’ve ever used effect pedals, you know they come in an
infinite array of effects, colors and sizes. If you use multiple
pedals, you probably do so by linking them all together into a
chain. The AcoustiFX eliminates the need for so many pedals
because in addition to turning your electric into an acoustic,
this pedal also combines just about all the effects you need
4
Introduction

into one unit. Instead of turning knobs and pushing buttons
on pedal after pedal, with the AcoustiFX you have full
control over dozens of effects with one foot pedal! It’s that
easy.
Effect Modules
If you were to think of the AcoustiFX as a series of individual
pedals linked together, then each pedal in that series would be
considered an effect module. The AcoustiFX has eight
separate effect modules, as shown below:
You can assign one effect to each of these modules and
adjust its parameters accordingly. On the face of the unit,
you’ll see a list of possible effect types for some of these
modules. For more on effect modules, see chapter 10.
Effect Types
When we use the word “effect” in this manual, we’re usually
referring to an effect type. Each module provides you with a
selection of effect types, only one of which may be chosen
for each module. For example, the TYPE module allows you
to select which type of acoustic sound you want (Clean,
Warm, Bright, Rhythm and others). The behavior of each of
these effect types may be adjusted in one or more ways to
produce variations of the effect.
Parameters
A parameter is a control that changes the characteristics of an
effect. When we use the word “parameter,” we are referring
to the “direct control” parameter available to the FX1 and
FX2 modules. The parameters for FX1 and FX2 are labeled
PARAM on the face of the AcoustiFX. The characteristic
controlled by a parameter varies from effect to effect.

Introduction
Programs
A program is a combination of effects modules and
their respective settings. In PLAY mode, you have
quick access to the AcoustiFX’s 40 programs via the
foot pedals and the VALUE knob. The programs are
divided up into banks A – D and are identified by a bank
letter and a program number on the display.

How to Use This Manual
This manual is divided into the following sections describing
the various functions and applications for the AcoustiFX.
While it’s a good idea to read through the entire manual once
carefully, if you already have general knowledge about effects,
you should use the table of contents to look up specific
functions.
Helpful tips and advice
are highlighted in a
shaded box like this.
Chapter 3: Getting Started shows you how to get the unit
connected and turned on. We’ve included a hookup diagram
and some tips on using the AcoustiFX.
Chapter 4: A Tour of the AcoustiFX describes all the controls
and features of the unit. This chapter features diagrams of the
top and rear panels that are labeled with the name and a brief
overview of each function. The paragraphs that follow the
diagrams provide in-depth description of these features.
Chapters 5 through 9 include step-by-step instructions for using
the AcoustiFX, including how to select and edit programs,
use the tuner function, store and copy programs, and defer
program changes.
Chapter 10: Effects Knob Settings explains the unit’s effect
modules and types, as well as other settings controlled by the
EFFECT and VALUE knobs.
When something
important appears in
the manual, an
exclamation mark (like
the one shown at left)
will appear with some
explanatory text. This
symbol indicates that
this information is vital
when operating the
AcoustiFX.
Chapter 11: Troubleshooting can give you a hand if you’re
experiencing problems with the AcoustiFX. You’ll find that
most issues can be resolved simply and quickly.
Chapter 12: Specifications is full of information for the more
technical users.
Chapter 13: Warranty/Contact Alesis explains the warranty we
supply with the AcoustiFX and lets you know the best way to
reach us if you have any questions or comments.

3 Hookup Diagram
The first thing we’ll show you is how to get your AcoustiFX
up and running. The following diagram shows you the most
common method of hooking up your AcoustiFX, but there
are other ways of doing it. For example, you may decide to
run the AcoustiFX straight into your mixer or recording
device instead of an amplifier. You may even want to go so
far as to use the AcoustiFX to add effects to other mic’d
acoustic instruments such as brass, strings, woodwinds, piano
and even voice.
16
When you plug an
adapter into the
AcoustiFX while
batteries are in the unit,
it will be powered by
the adapter and not the
batteries.

Display
This LED display is made up of two digits and two decimal
points. In PLAY mode, the digits indicate the current bank
letter and program number. When you turn the EFFECT
knob to a module or parameter, the two digits display the
setting of the selection. Descriptions of settings for each
mode and parameter are in chapter 10.
When either of the
decimal points on the
display is flashing,
battery power is low
and about to run out.
The Display also contains two decimal points, each to the
right of one of the digits. The # decimal point is used by the
17
4
A Tour of the AcoustiFX
AcoustiFX’s tuner to help indicate the pitch of a note you’re
playing, and the EDITED decimal point lights up when you
have changed the settings of the current program. You can
read more about these in chapter 6, “Editing Programs,” and
chapter 7, “Using the Tuner.”
EFFECT knob
The EFFECT knob is used for selecting effect modules,
parameters and other settings to edit. Around the knob, you’ll
see the names of sixteen different settings, including eight
effect modules (EQ is a single module made up of five
separate settings), two effect parameters (labeled PARAM)
and a program-level setting (LEVEL). The PLAY setting is
what you’ll want to be in while playing your guitar through
the AcoustiFX.
Refer to chapter 10 for descriptions of the possible values for
the EFFECT knob’s settings.
VALUE knob
In PLAY mode, this knob lets you select a program. When
you make a selection other than PLAY with the EFFECT
knob, you are in edit mode, and the VALUE knob allows you
to change the setting of the mode, parameter or global setting
you have selected. Also, you can press this knob to store
changes you have made to a program.
Foot Pedals
While in PLAY mode, the left foot pedal decrements the
program number, and the right foot pedal increments the
program number. When you press both pedals together, the
AcoustiFX goes into bypass mode, in which the audio signal
from your guitar simply passes through the AcoustiFX
without being affected. When you hold both foot pedals
down for longer then half a second, the AcoustiFX goes into
mute mode, in which no signal at all leaves the AcoustiFX.
When you are in bypass or mute mode, the tuner is activated.
18
While in PLAY mode, if
you press and hold the
VALUE knob for longer
than half a second, the
display will change to
the current master
volume setting (1 to 30).
Default volume is 21
(unity gain) and each
number indicates a 2dB
change from the
number above or below
it. Unlike LEVEL,
which indicates the
level of an individual
program, the master
volume is a global
setting that is
remembered each time
the unit is turned off.

mode (turn the EFFECT knob
to PLAY).
3.
Change programs in one of
these two ways:
1
3
2
Foot pedals
This is the easiest way to
switch programs, especially
while playing your guitar. Just
step on the left foot pedal
to decrement the program
number and the right to
increment it. You can hold
down a pedal to increment or
decrement programs continuously.
VALUE knob
You also can turn this knob to switch programs.
4.
20
Play your guitar to hear how the program affects the
sound.
3
6 Editing Programs
To Edit a Selected Program
1.
Select a program to edit using the
foot pedals or VALUE knob.
2.
Turn the EFFECT knob to the
effect module or parameter you
wish to modify.
3.
Turn the VALUE knob to
select an effect type or value for
the module. As soon as you
change the value, the EDITED
decimal point on the display
lights up to show you a change
has been made to the current
program.
2
1
4
4.
If the module has a parameter
(PARAM), turn the EFFECT
knob to select the parameter.
5.
Using the VALUE knob, select a
value for the parameter.
6.
Continue in this way until you have completed
assignments for all modules and parameters.
To Restore Factory Presets
Once you have saved changes to a preset program, you can
still recall the original settings. To enter RESTORE
FACTORY PRESETS mode, simply hold down the VALUE
knob as you turn the unit on and then select the program to
for all programs). Press the VALUE
be restored (or
knob to confirm your selection. Any program changes you
have made will be lost, so you might want to copy the
program to another location first. See chapter 8 for
instructions on how to copy programs.
3
5
1
To toggle an effect
module on and off,
press both pedals while
the effect module is
selected.
Just turn the EFFECT
knob to exit the
RESTORE FACTORY
PRESETS mode, or
turn the unit off and
then on again.
21
7 Using the Tuner
To Tune Your Guitar
1.
In PLAY mode, enter BYPASS
by pressing both foot
mode
pedals at the same time once, or
2
3
enter MUTE mode
by
holding them both down for
more than half a second. The
display will now show tuning
information.
2.
Make sure your guitar is
connected to the AcoustiFX,
and play the open string you
wish to tune. The left digit of
the display indicates the pitch
nearest that of the open string.
If the # decimal point is lit, the
note is a sharp. If it is not lit,
the note is a natural.
3.
Look at the right digit of the
display to determine if the pitch is correct.
If the top four segments of the digit are rotating
clockwise, then your guitar’s pitch is higher than the
pitch shown in the first digit. If the bottom four
segments are rotating counterclockwise, the pitch is low.
The more the pitch is off, the faster the rotation. If no
pitch is detected, you’ll see a dash in the left digit.
4.
Tune the string until an 8 appears in the second digit,
indicating that the string is in tune with the pitch
displayed in the left digit.
The visual guide on the next page shows you what
you’ll see on the display while tuning your guitar.
22

Using the Tuner
7
Changing Pitch Reference
If you turn the VALUE knob while using the tuner, the
display shows you the setting for the AcoustiFX’s pitch
) for the A
reference, which is set to 440Hz (shown as
note above middle C. The possible range of values for this
setting is 35 to 45, which represents 435Hz to 445Hz.
When you turn the AcoustiFX on and off again, the reference
pitch is reset to 40.
While you are viewing
or editing the pitch
reference, the display
will return to pitch
indication if you do not
turn the VALUE knob
for more than two
seconds.
23
8 Storing & Copying Programs
To Store a Program
1.
In PLAY or EDIT mode, press
the VALUE knob. The display
will flash the current program
number.
2.
Use the VALUE knob or the
foot pedals to select the
program number where the
current program will be stored.
If you want to save it in the
same program number, you
can skip this step.
3.
Press the VALUE knob again
to store the program in the
selected place. The AcoustiFX
then returns to the mode it
was in before you began the
store operation, and the
destination program becomes the
current program.
To Copy a Program
A copy is just a store of a program that hasn’t been modified,
so just follow the same steps as you would to store a program.
24
1
3
2
The store operation
times out if you do
nothing for more than
five seconds. You also
can abort the operation
by turning the EFFECT
knob to a different
position.
9 Deferred Program Change
When you switch programs, the AcoustiFX normally changes
immediately to the program shown on the display. However,
in some situations—especially when playing live—you may
want the ability to scroll through program numbers while
remaining in the current program setting. For example, let’s
say you’re performing in program A3, which gives you clean
sound with slight reverb. If you want to scroll up to program
C6 for a larger sound with an echo while you continue
playing, you’ll have to be in deferred program-change mode,
which allows you to defer a program change until you
confirm it. Here’s how:
To Defer Program Change
1.
As you turn on the AcoustiFX, hold down either foot
pedal. Letters will scroll by on the display, spelling the
word “deferred.”
2.
While in PLAY mode, step on one of the foot pedals or
turn the VALUE knob to change the program number.
You’ll notice that the AcoustiFX remains in the
program it was in before you changed the program
value. Also, the display will flash the digit that is
different from the currently selected program. For
example, if you are playing in program D5 and scroll up
to program D7, the 7 will flash. If you scroll down to
B2, both digits will flash.
3.
Once the display shows the program number you desire,
to
step on both foot pedals at the same time
confirm the program change. The display will stop
flashing and the AcoustiFX will switch to the new
program.
4.
To return to normal program-change mode, turn off

10 EFFECT Knob Settings
Following are descriptions of each of the effect modules (and
other settings of the EFFECT knob), along with their effect
types and parameters.
PLAY
In this setting, the display shows you the current program number. This is the
mode in which you should be performing, as it allows you to easily switch
programs via the foot pedals.
Indicates the bank letter and program number of the current
program.
COMP/LIMIT (Compressor/Limiter)
Compression evens out the highs and lows of your sound by squeezing them
into a thinner range of levels, bringing down the louder levels and boosting the
quieter ones. Limiting eases only the high levels.
Provide increasing levels of compression.
Provide increasing limiting.
Turns COMP/LIMIT off.
TYPE
Many factors affect the sound of an acoustic guitar, including its size, the type
and thickness of the wood, and the make of amplifier. The TYPE effect module
allows you to capture a number of these acoustic-guitar sounds.
Clean
The clean, natural sound of a quality acoustic guitar.
Warm
A dark, deep sound typical of guitars made of dense rosewood or
mahogany.
27
10
EFFECT Knob Settings
Bright
Accentuates the higher frequencies for a crisp sound usually found
in acoustics with smaller bodies.
Rhythm
A full, warm sound that’s great for strumming rhythm parts.
Jumbo
Provides a little more low-end for that sound associated with largebody acoustics.
Drive
Adds a crunch to your acoustic sound, as if you’re playing through
a tube amplifier and pushing the gain. Higher values mean more
drive.
Off
Turns TYPE off.
EQ (Equalizer)
This module provides you with a high-pass filter and four bands of equalization
that you can use to shape the sound of your audio signal by cutting and boosting
certain frequencies.
HPF (High-Pass Filter)
This filter eliminates unwanted low frequencies by cutting out all frequencies
lower than 80 Hz when activated. Frequencies higher than 80 Hz are allowed to
pass (thus the name “high-pass filter”). This is very useful for getting rid of noise
caused by air conditioners, passing cars or other low-frequency rumble (great if
you’re recording at home).
Turns on the high-pass filter.
Turns off the high-pass filter.
LOW
This is a single-pole low-shelf filter at 150Hz. This works by allowing you to
boost or cut all of the frequencies below 150Hz. Use the LOW band to adjust
the bass in your guitar signal.
28
EFFECT Knob Settings
10
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the LOW EQ band.
LO MID
This EQ band is a parametric band at 700Hz with a Q of 1.5. This type of EQ
works by boosting or cutting at 700Hz, along with a band of frequencies above
and below 700Hz. Q determines the range of frequencies affected (the
bandwidth). A Q value of 1.5 is an optimal setting for most EQ applications.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the LO MID EQ band.
HI MID
This band is a parametric band at 2.5kHz with a Q of 1.5.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the HI MID EQ band.
HIGH
This is a single-pole high shelf filter at 5kHz. This works by allowing you to
boost or cut the 5kHz frequency, along with all of the frequencies above that.
Use the HIGH band to control the highest frequencies in your guitar signal.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the HIGH EQ band.
EDGE
This is a filtered limiter that gives your acoustic guitar a bright, edgy sound. This
effect works by taking the original signal, filtering out all frequencies that fall
below 2kHz, feeding that into a limiter and then mixing it back with the original,
unfiltered, unlimited sound.
Increasing amounts of edge.
Turns off EDGE.
29
10
EFFECT Knob Settings
HUM CANCEL
The hum canceller eliminates unwanted low-end hum by eliminating the
frequency that contains the hum (60Hz). Unlike the high-pass filter, this mode
allows you to control how much noise you want to eliminate. If the high-pass
filter is turned on, you do not need to use the hum canceller.
Increasing levels of hum elimination (60Hz harmonic notch filters).
Turns off the hum canceller.
NOISE GATE
The noise gate eliminates unwanted noise by gating the signal, which means that
it mutes the signal until the signal’s level rises above a certain point.
Increasing levels of gate threshold.
Turns off the noise gate.
FX1 (Multi-Effect Module 1, Stereo Effects)
This module gives you a choice of stereo effects. You assign one effect at a time
to this module.
Chorus
Adds fullness to your sound by emulating a chorus of multiple
instruments. Higher values indicate greater modulation depth.
Pedal Chorus
A Chorus effect whose modulation depth is controlled by the
control pedal.
Phaser
An effect that shifts the phase of the signal and adds it to the
original sound (in simpler terms, it adds a duplicate signal that is
delayed a bit). The phaser gives your guitar a full, pulsating sound.
Higher values result in more feedback, producing a more intense
effect.
Pedal Phaser
A phaser effect whose feedback is controlled by the control pedal.
30
EFFECT Knob Settings
10
Flanger
Shifts the pitch of the signal up and down, creating a swirling
effect. Higher values result in more feedback.
Pedal Flanger
A flanger whose delay is controlled by the control pedal.
Tremolo
Varies the volume of the signal, creating a rising and falling effect.
Higher values result in greater depth of variation.
Pedal Tremolo
A tremolo effect whose depth is controlled by the control pedal.
12-String
Emulates the crisp, full sound of a 12-string guitar by creating the
impression that your guitar has six additional strings that are tuned
an octave higher than the original six.
Pedal 12-String
A 12-string effect whose intensity is controlled by the control
pedal.
Slow Attack
Reduces the attack rate of the signal, slowing the rate at which the
volume of the sound rises when you attack a string. Higher values
result in higher sensitivity.
Random Sample and Hold Step Filter
Filters the signal with a cutoff frequency that changes to a new
random value at fixed time intervals, producing an arpeggiator-like
sound.
Pedal Step Filter
A step filter whose depth is controlled by the control pedal.
Auto Wah
The classic auto wah sound that we all know and love. U1 – U4 are
the standard, upward-sweeping variations with varying
attack/release rates. U5 – U9 are downward-sweeping variations
with varying attack/release rates.
31
10
EFFECT Knob Settings
Pedal Wah
A wah sound controlled by moving the control pedal up and down
as you play.
Rotary Speaker
Emulates the sound of the classic rotary, creating a Doppler effect
similar to that achieved by an organ’s rotating speaker. Higher
values result in greater intensity and pan depth.
Pedal Rotary Speaker
A rotary speaker effect whose intensity and pan depth are
controlled by the control pedal.
Cry
Creates an effect similar to that of a voice box, adding a human-like
crying effect to the sound. Higher values result in faster
attack/release rates.
Pedal Cry
A cry effect whose intensity is controlled by the control pedal.
Off
Turns off FX1.
PARAM (Direct-Control Parameter for FX1)
This parameter modifies the operation of the effect selected for the FX1
module. Changing between effect types with dissimilar value ranges will scale
this value accordingly. For example, if you set Phaser to PARAM=63 and then
switch to the Auto Wah effect, its PARAM value will be 12. Changing back to
Phaser will result in a PARAM value of 63.
Indicates the value of FX1’s direct-control parameter, according to
the following:
For Phaser, Tremolo, Step Filter, Flanger and Chorus, indicates the
rate of the effect.
For Slow Attack, indicates the rate of the attack.
For Rotary Speaker, indicates the rate of the speaker rotation.
32
EFFECT Knob Settings

For Cry and Auto Wah, indicates the attack/release rate.
Indicates that the control pedal controls the parameter.
Indicates that the effect assigned to the FX1 module does not have
a direct-control parameter (for example, 12-String, Pedal Wah or
Pedal Cry) or that FX1 is off.
FX2 (Multi-Effect Module 2, Delay-Based Effects)
This module gives you a choice of delay-based effects. A delay is an echo of the
original signal that can occur at varying frequency and time.
Hall Reverb
Simulates the effect of sound waves bouncing off of the walls of a
concert hall. Higher values indicate a wetter mix.
Pedal Hall Reverb
A Hall Reverb effect whose wet/dry mix is controlled by the
control pedal.
Room Reverb
Simulates the effect of sound waves bouncing off of the walls of a
room. Higher values indicate a wetter mix.
Pedal Room Reverb
A Room Reverb effect whose wet/dry mix is controlled by the
control pedal.
Plate Reverb
Recreates the classic “plate reverb” sound achieved by using a
metal plate. Higher values indicate a wetter mix.
Pedal Plate Reverb
A Plate Reverb effect whose wet/dry mix is controlled by the
control pedal.
Reverse Reverb
Creates a backwards-playing reverb that you hear immediately
before you hear the original signal, instead of after it. Higher values
indicate a wetter mix.
33
10
EFFECT Knob Settings
Pedal Reverse Reverb
A Reverse Reverb effect whose wet/dry mix is controlled by the
control pedal.
Doubling
Doubles the signal with a slight delay, creating the effect of two
instruments playing at once. Higher values indicate higher intensity.
Pedal Doubling
Doubling effect whose intensity is controlled by the control pedal.
Stereo Delay
A standard delay that occurs in stereo. Higher values indicate more
feedback, producing a longer-repeating echo.
Pedal Stereo Delay
A Stereo Delay effect whose feedback level is controlled by the
control pedal.
Ping Pong Delay
Creates a delay that bounces back and forth between the right and
left sides of the stereo spectrum. Higher values indicate more
feedback.
Pedal Ping Pong
Ping Pong Delay effect whose amount of feedback is controlled by
the control pedal.
Tape Delay
Emulates the retro tape-delay effect that was created by recording a
signal to tape and playing it back as a delay. Higher values indicate
more feedback.
Pedal Tape Delay
A Tape Delay effect whose feedback is controlled by the control
pedal; great for singling out notes or sections to echo.
Echo
An echo for which higher values indicate a wetter signal and lower
values indicate a drier signal.
Pedal Echo
An echo whose wet/dry mix is controlled by the control pedal.
