Introduction

About the AcoustiFX
The first thing youll probably notice about the AcoustiFX is its sizeits not much larger or smaller than most other effect pedals. But dont let that fool you. The AcoustiFX does much more than most pedals youll find on the market today (and for an unbeatable price too). Weve packed a lot of effects and other features into this unit. Heres a glimpse:

AcoustiFX Key Features

Audio processing thats made specifically for micd 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 AcoustiFXs features
AcoustiFX Basics Benefits of a Multi-Effects Pedal
If youve 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
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! Its 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, youll 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, were 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.

Programs

A program is a combination of effects modules and their respective settings. In PLAY mode, you have quick access to the AcoustiFXs 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 its 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. Chapter 3: Getting Started shows you how to get the unit connected and turned on. Weve 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 units effect modules and types, as well as other settings controlled by the EFFECT and VALUE knobs. Chapter 11: Troubleshooting can give you a hand if youre experiencing problems with the AcoustiFX. Youll 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.

Helpful tips and advice are highlighted in a shaded box like this.

3 Hookup Diagram

The first thing well 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 micd acoustic instruments such as brass, strings, woodwinds, piano and even voice.
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.

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. The Display also contains two decimal points, each to the right of one of the digits. The # decimal point is used by the
When either of the decimal points on the display is flashing, battery power is low and about to run out.

A Tour of the AcoustiFX

AcoustiFXs tuner to help indicate the pitch of a note youre 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.
The EFFECT knob is used for selecting effect modules, parameters and other settings to edit. Around the knob, youll 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 youll want to be in while playing your guitar through the AcoustiFX. Refer to chapter 10 for descriptions of the possible values for the EFFECT knobs settings.
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.
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.

Rear Panel

The rear panel is where youll connect the power source, optional control pedal and your guitar and amplifier. Its important that you use the right types of plugs in these jacks. Be sure to follow these guidelines.

5 Selecting Programs

After youve plugged everything in, youll probably want to check out the factory presets we programmed into the AcoustiFX. This chapter shows you how to do that.

To Select Programs

1. Make sure the AcoustiFX is hooked up properly and turned on, as outlined in chapter 3. Make sure youre in PLAY mode (turn the EFFECT knob to PLAY). Change programs in one of these two ways: 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. Play your guitar to hear how the program affects the sound.

6 Editing Programs

To Edit a Selected Program
1. 2. Select a program to edit using the foot pedals or VALUE knob. Turn the EFFECT knob to the effect module or parameter you wish to modify. 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. If the module has a parameter (PARAM), turn the EFFECT knob to select the parameter. Using the VALUE knob, select a value for the parameter. Continue in this way until you have completed assignments for all modules and parameters.
To toggle an effect module on and off, press both pedals while the effect module is selected.
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.
Just turn the EFFECT knob to exit the RESTORE FACTORY PRESETS mode, or turn the unit off and then on again.

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 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. 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 guitars 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, youll see a dash in the left digit. 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 youll see on the display while tuning your guitar.

Using the Tuner

Changing Pitch Reference
If you turn the VALUE knob while using the tuner, the display shows you the setting for the AcoustiFXs 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.
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.
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. 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 hasnt been modified, so just follow the same steps as you would to store a program.
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 situationsespecially when playing liveyou may want the ability to scroll through program numbers while remaining in the current program setting. For example, lets say youre 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, youll have to be in deferred program-change mode, which allows you to defer a program change until you confirm it. Heres 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. While in PLAY mode, step on one of the foot pedals or turn the VALUE knob to change the program number. Youll 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. 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. To return to normal program-change mode, turn off the AcoustiFX and turn it back on without holding down either foot pedal.
Deferred programchange mode is especially useful when youre performing and want to switch easily between settings as you continue playing.

Deferred Program Change

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.
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.
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.

EFFECT Knob Settings

Bright Accentuates the higher frequencies for a crisp sound usually found in acoustics with smaller bodies. Rhythm A full, warm sound thats 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 youre playing through a tube amplifier and pushing the gain. Higher values mean more drive. Off Turns TYPE off.

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.
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 organs 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 FX1s 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.

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.
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.
