Terms Used in This Manual
This section explains some important terms that are used throughout the A2.1u documentation.
■ Effect module
As shown in the illustration above, the A2.1u 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 A2.1u, 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 A2.1u, effect module combinations are stored
and called up in units referred to as patches. A patch
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 A2.1u 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 A2.1u 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 A2.1u 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).
Operating the A2.1u on batteries
Turn the A2.1u over and open the cover
of the battery compartment on the bottom.

it and then raise the cover.
1. Insert four fresh IEC
R6 (size AA) batteries. 2. Close the cover of
the battery compartment. 3.

(size AA) batteries
Insert batteries facing
in alternate directions.
Use four IEC R6 (size AA) batteries.
When the batteries are getting low, the
indication "bt" appears on the display.
Push the cover in until the
latch audibly snaps into
place.
