Features
Thank you for selecting the ZOOM B2 (hereafter simply called the "B2"). The B2 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 carves out a sonic outline in superb detail while preserving the original sound character of the bass guitar.
●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 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 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 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 effectively not only for a live performance but also when feeding the signal directly to a recorder.
● 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 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.
● Easy operation with foot switch and expression pedal
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 switching effect programs, setting the tempo for the rhythm function, or switching delay hold on and off. The expression pedal can be used to adjust the volume or the tonal quality of an effect 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.

Terms Used in This Manual
This section explains some important terms that are used throughout the B2 documentation.
IN 
COMP/LIMIT WAH/EFX DRIVE/SYNTH ZNR/MIX LO EQ HI EQ MOD/SFX DELAY REVERB
OUT
■ Effect module
As shown in the illustration above, the B2 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 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.
■ Patch
In the B2, 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 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 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, you use the format "A1" (patch number 1 from bank A), "06" (patch number 6 from bank 0), etc.
■ Play mode/edit mode
■ Effect parameter
All effect modules have various parameters that can be adjusted. These are called effect parameters.
In the B2, 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.
The internal status of the B2 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.

To try out the various effects of the B2, we recommend that you simply play your instrument while switching patches.
Turn power on
Use a shielded cable with mono phone plug to connect the bass guitar to the [INPUT] jack of the B2.
When using the B2 with the AC adapter, plug the adapter into the outlet and plug the cable from the adapter into the [DC IN] jack on the B2.
Set the [POWER] switch on the rear panel of the B2 to ON.
Turn the bass guitar amplifier on and adjust the volume to a suitable position.
Set the B2 to play mode
If the Module selector is set to a position other than "PLAY", set it to "PLAY".
The bank and patch that were selected when the power was last turned off will appear on the display.
A1
Bank name Patch number
HINT Immediately after turning the B2 on, the unit will be in play mode, even if the Module selector is set to a position other than "PLAY".
Select a patch
To switch the patch, press one of the [W]/[Q] foot switches.
Pressing the [W] foot switch calls up the next lower patch, and pressing the [Q] foot switch calls up the next higher patch.
Repeatedly pressing one foot switch cycles through patches in the order A0 – A9 ... d0 – d9 → 00 – 09 ... 30 – 39 →A0, or the reverse order.

Selecting a Patch
Adjust tone and volume
To adjust the effect sound and volume levels in play mode, the Parameter knobs 1 – 3 can be used. Each knob controls a specific parameter.
Parameter knob 1
Adjusts the CABINET parameter of the DRIVE/SYNTH module (cabinet simulator effect intensity).
Parameter knob 3
Adjusts the PATCH LEVEL parameter (output level of the entire patch).
Parameter knob 2
Adjusts the TONE parameter of the DRIVE/SYNTH module (mainly distortion sound character).
When you turn a Parameter knob, the corresponding LED lights up and the display briefly shows the current value of the respective parameter.
NOTE • If the DRIVE/SYNTH module is set to OFF for the currently selected module
(indication "oF" is shown on the display), Parameter knobs 1 and 2 have no effect.
• The higher the setting value of Parameter knob 1 (CABINET parameter), the more will the cabinet character be emphasized.
• Changes made here are temporary and will be lost when you select another patch. To retain the changes, store the patch in the user area.
• The master level in common to all patches is set in edit mode (→ p. 30).
Directly selecting a bank
To select the banks A – d, 0 – 3 directly, use the BANK [-]/[+] keys.
Pressing the BANK [-] key calls up the next lower bank, and pressing the BANK [+] key calls up the next higher bank.

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

MT
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 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 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.
Play the string to tune
Play the open string to tune,
and adjust the pitch.
