Features
Thank you for selecting the ZOOM B2.1u (hereafter simply called the " B2.1u "). The B2.1u is a multi
effect processor with the following features and functions.
●
Latest technology for outstanding performance
96 kHz / 24 bit sampling (with 32 bit internal processing) assures excellent sound quality. The B2.1u
carves out a sonic outline in superb detail while preserving the original sound character of the bass guitar.
The B2.1u also has a USB connection and can be used as a direct bass guitar/computer interface.
●
Versatile palette of effects
Out of a total of 47 effects, up to nine (including ZNR) can be used simultaneously. The dazzling choices
provided by the B2.1u include distortion effects modeled on famous amps and compact effects, compressor/
limiter effects for dynamic punch, a parametric equalizer essential for working on sonic nuances, as well as
various delay and modulation effects. Both in quality and versatility, the B2.1u far surpasses anything in its
class. You can even transform the output into a cool synth bass or fretless bass sound.
●
Really usable patches straight out of the box
Effect module combinations are stored and called up in units referred to as patches. The B2.1u comes
with a full complement of 40 read-only plus 40 user-programmable patches, giving you 80 great reasons
to start grooving.
●
Great for live performances and direct recording
The distortion effects have a special parameter that selects whether to apply only the head amp
characteristics or add also the cabinet sound. This lets you use the B2.1u effectively not only for a live
performance but also when feeding the signal directly to a recorder.
●
XLR connector for direct output
In addition to the [OUTPUT/PHONES] jack, the B2.1u features an XLR connector for sending a
balanced line-level signal to equipment such as a PA mixer or recording console. The signal can be
derived from a point before or after effect processing. A ground lift switch is also provided, which is
useful to prevent hum in the direct output caused by ground loops.
●
Integrated auto-chromatic tuner and rhythm functions
Realistic PCM sound sources are available to auto-play a number of rhythm patterns. This is convenient
for use as a metronome during practice or to provide a simple rhythm part for a quick session. An autochromatic tuner for bass guitar is also built right into the unit, including a function for silent tuning
which lets you easily tune your instrument on stage.
●
Sophisticated user interface
The combination of a rotary type selector and three parameter knobs make the effect editing process
intuitive and quick. The mute interval when switching patches has been reduced to less than 8
milliseconds. Seamless patch changing is now a reality.
●
Dual power supply principle allows use anywhere
The B2.1u can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous
operating time on batteries is approximately 6 hours with alkaline batteries.
●
Easy operation with expression pedal and foot switch
An optional foot switch (FS01) or expression pedal (FP01/FP02) can be connected to the [CONTROL
IN] jack. The foot switch is convenient for quickly toggling effect programs, setting the tempo of the
rhythm function, turning delay hold on and off, etc. A connected expression pedal lets you adjust the
volume in real time.
Please take the time to read this manual carefully so as to get the most out of the unit and to ensure
optimum performance and reliability.

ZOOM B2.1u
Terms Used in This Manual
This section explains some important terms that are used throughout the B2.1u documentation.
IN OUT
■
Effect module
As shown in the illustration above, the B2.1u can be
thought of as a combination of several single effects.
Each of these effects is referred to as an effect module.
In addition to modules comprising compressor and
limiter effects (COMP/LIMIT), amp simulator/synth
bass effects (DRIVE/SYNTH), and modulation/special
effects (MOD/SFX), the B2.1u also provides a module
for ZNR (ZOOM Noise Reduction). Various
parameters such as effect intensity can be adjusted for
each module individually, and modules can be
switched on and off as desired.
■
Effect type
Within some effect modules, there are several
different effects which are referred to as effect types.
For example, the modulation/SFX effect module
(MOD/SFX) comprises chorus, flanger, pitch shifter,
delay, and other effect types. Only one of these can
be selected at a time.
■
Effect parameter
All effect modules have various parameters that can
be adjusted. These are called effect parameters.
In the B2.1u, 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.
LO EQZNR/MIXDRIVE/SYNTHCOMP/LIMIT WAH/EFX MOD/SFXHI EQ DELAY REVERB
■
Patch
In the B2.1u, 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 B2.1u holds up to 80 patches
(including 40 patches which allow read/write).
■
Bank and area
A group of ten patches is called a bank. The memory
of the B2.1u 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. Banks 0 to 3 are the
preset area containing read-only patches.
The patches within each bank are numbered 0
through 9. To specify a patch of the B2.1u, you use
the format "A1" (patch number 1 from bank A), "06"
(patch number 6 from bank 0), etc.
■
Play mode/edit mode
The internal status of the B2.1u is referred to as the
operation mode. The two major modes are "play
mode" in which you can select patches and use them
for playing your instrument, and "edit mode" in
which you can modify the effects. The module
selector serves for switching between the play mode
and edit mode.

Using the Tuner
The B2.1u 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 B2.1u to the bypass
In play mode, press both [W]/[Q] foot
switches together briefly and release.
Setting the B2.1u to the mute state
In play 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
B2.1u 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 B2.1u 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.
