only alkaline types.
[AC adapter operation]
• Be sure to use only an AC adapter which supplies 9 V DC,
300 mA and is equipped with a "center minus" plug
(Zoom AD-0006). The use of an adapter other than the
specified type may damage the unit and pose a safety
hazard.
• Connect the AC adapter only to an AC outlet that supplies
the rated voltage required by the adapter.
• When disconnecting the AC adapter from the AC outlet,
always grasp the adapter itself and do not pull at the cable.
• During lightning or when not using the unit for an
extended period, disconnect the AC adapter from the AC
outlet.
[Battery operation]
• Use four conventional IEC R6 (size AA) batteries
(alkaline).
• The A2 cannot be used for recharging.
•Pay close attention to the labelling of the battery to make
sure you choose the correct type.

Features
Thank you for selecting the
effect processor for acoustic guitar with the following features.
Latest technology for top performance
●
Excellent sound quality is assured by signal processing circuitry featuring 96 kHz/24 bit sampling and
internal 32-bit processing. Frequency response remains flat to 40 kHz, and signal-to-noise ratio is an
amazing 100 dB.
Full array of effects optimized for acoustic guitar
●
Out of a versatile palette of 47 effects, up to eight (including ZNR) can be used simultaneously. In
addition to standard effects such as compressor and delay/reverb, the A2 offers effects which simulate
the sound of famous acoustic guitars, a mic simulator, and other specialized acoustic guitar effects.
Select optimum characteristics for pickups and amps
●
The A2 allows you to select the best frequency response for your pickup and amp. This is great for
eliminating sonic problems that can occur when playing an acoustic guitar through a guitar amplifier.
Automatic suppression of acoustic feedback
●
The feedback control feature pinpoints the frequency where acoustic feedback (howling) occurs and
provides an efficient cure. The function can be activated by foot switch during a performance.
●
Advanced interface
Rotary selectors and three parameter knobs make operation extremely quick and intuitive. The muting
interval when switching patches has been reduced to less than 8 milliseconds, allowing virtually
seamless patch changes.
ZOOM A2
(simply called the "A2" in this manual). The A2 is a sophisticated
●
Rhythm function and auto-chromatic tuner
Rhythm patterns created from highly realistic PCM sources are convenient for use instead of a
metronome during practice or for quick session work. The auto-chromatic tuner designed for guitar
makes tuning a snap.
●
Support for foot switch and expression pedal
By connecting an optional foot switch (FS01) to the CONTROL IN jack, you can switch banks, specify
the rhythm tempo, and switch feedback control on and off with your foot. Or use an expression pedal
(FP01/FP02) to vary the volume or tone in real time.
●
Dual power supply principle allows use anywhere
The A2 can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous operating
time on batteries is approximately 7.5 hours with alkaline batteries.
Please take the time to read this manual carefully, in order to get the most out of your A2 and to ensure
optimum performance and reliability.

Terms Used in This Manual
This section explains some important terms that are used throughout the A2 documentation.
INMODELMIC
■
Effect module
As shown in the illustration above, the A2 can be
thought of as a combination of several single effects.
Each of these is referred to as an effect module.
Among others, there is a module for ZNR (ZOOM
Noise Reduction), as well as a modeling (sound
simulation) module (MODEL), compressor/limiter
module (COMP/LIMIT), modulation/special effects
module (MOD/EFX). Parameters such as effect
intensity can be adjusted for each module individually,
and modules can be switched on and off.
■
Effect type
Most effect modules comprise several different effects
which are referred to as effect types. For example, the
MOD/EFX module comprises chorus, flanger, delay,
phaser, and other effect types. Only one of these can
be selected at any time.
■
Effect parameter
All effect modules have various parameters that can
be adjusted. These are called effect parameters.
In the A2, effect parameters are adjusted with the
parameter knobs 1 - 3. Similar to the knobs on a
compact effect, these change aspects such as tonal
character and effect intensity. Which parameter is
assigned to each knob depends on the currently
selected effect module and effect type.
■
Patch
In the A2, effect module combinations are stored and
called up in units referred to as patches. A patch
COMP/LIMIT
LO EQHI EQZNR
MOD/EFX
comprises information about the on/off status of each
effect module, about the effect type used in each
module, and about effect parameter settings. The
internal memory of the A2 holds 80 patches (40 of
these can be rewritten by the user).
●
Bank and area
A group of ten patches is called a bank. The memory
of the A2 comprises a total of eight banks, labelled A
to d and 0 to 3. Banks A - d form the user area which
allows read/write patches. Banks 0 to 3 are the preset
area of read-only.
The patches within each bank are numbered 0
through 9. To specify a patch, you use the format
"A1" (patch number 1 from bank A), "06" (patch
number 6 from bank 0), etc.
■
Modes
The A2 has the following operation modes.
●
Play mode
In this mode, patches can be selected and played.
●
Manual mode
In this mode, you play your instrument while
using the foot switches to turn the MOD/EFX
module or the feedback control function on and
off. The mode also is used for automatic
detection of acoustic feedback frequency.
●
Edit mode
In this mode, the effect parameters of a patch can
be edited (changed).

• Changes made here are temporary and will be lost
when you select another patch. To retain the
changes, store the patch (→ p. 16).
• Besides the individual patch levels, the A2 also
allows adjusting the master level. This setting
affects all patches (→ p. 33).
Directly selecting a bank
9
Using the Tuner
The A2 incorporates an auto-chromatic tuner. To use the tuner function, the built-in effects must be
bypassed (temporarily turned off) or muted (original sound and effect sound turned off).
Switch to bypass or mute
Setting the A2 to the bypass condition
In play mode (or manual mode), press
both [W]/[Q] foot switches together
briefly and release.
Setting the A2 to the mute condition
In play mode (or manual mode), press
both [W]/[Q] foot switches together
and hold for at least 1 second.
Patch change at bypass/mute
When you press both [W]/[Q] foot switches together while
playing your instrument, the bypass/mute condition is
activated. However, the sound may change momentarily
just before the condition is activated. This is because the
A2 switches to the next higher or lower patch when one of
the foot switches is pressed slightly earlier. (When you
cancel the bypass/mute condition, the original patch
number will be active again.)
This kind of behavior is not a defect. It is due to the very
high speed at which the A2 responds to patch switching.
To prevent the sound change caused by the above
condition, do not produce sound with your instrument until
the bypass/mute condition is fully established.

type
For some effect modules, you can select an effect
type from several possible choices. For example,
the MOD/EFX module comprises CHORUS,
FLANGER, and other effect types from which
you can choose one. The MODEL module is an
effect for simulating the sound of various types of
acoustic guitars. Switching effect types here
means selecting different guitar body sounds.
CONTROL module and
GLOBAL module
Besides the above modules, the A2 also
incorporates a CONTROL module and GLOBAL
module. The CONTROL module comprises
settings such as expression pedal and foot switch
function allocation, as well as the master level
that applies to all patches.
ZOOM A2
The GLOBAL module lets you optimize the A2
characteristics to fit the requirements of pickup
and guitar amp. It contains the following settings.
●
AMP SELECT
This parameter serves to optimize the frequency
response of the A2 to fit the type of amplifier. It
can be helpful to reduce the trebly sound that can
be a problem when playing an acoustic guitar
with a pickup through an amplifier. Settings with
different effect depth are available for Combo,
Stack, and other amp types.
●
PICKUP SELECT
This parameter serves to optimize the frequency
response of the A2 to fit the type of pickup. It can
also be used as a simulator for turning the sound
of an electric guitar into that of an acoustic guitar.

bright sound. Higher values result in stronger
attenuation effect.
Designed for use with regular combo type amplifiers.
C1 – C9
Higher values result in stronger attenuation effect.
Designed for use with stack type amplifiers. Higher
S1 – S9
values result in stronger attenuation effect.
This parameter serves for attenuating
frequency band that can sound harsh
when an acoustic guitar is reproduced
via a guitar amplifier (see table 6).
Choose the suitable setting depending
on the amplifier that is used, and adjust
the value as required.
