ZOOM B9.1ut
Terms Used in This Manual

■ Effect module

As shown in the illustration below, the B9.1ut can
be thought of as a combination of several single
effects. Each of these is referred to as an effect
module. The B9.1ut offers a compressor effect
module (COMP), amp simulator/synth bass effect
module (PRE-AMP), external effect loop control
module (EXT LOOP), and more. Parameters such
as effect intensity can be adjusted for each module
individually, and modules can be switched on and
off as desired.
The five modules EXT LOOP, ZNR, PRE-AMP,
EQ, and CABINET operate as a virtu al preamplifi er
which is controlled with the knobs and keys on the
pre-amp section of the panel.

■ Effect type

Most effect modules comprise several different
effects which are referred to as effect typ es. For
example, the modulation effect module (MOD/
EFX2) comprises chorus, flanger, pitch shift er,
delay, and other effect types. Only one of these can
be selected at any time.

■ Effect parameter

All effect modules have aspects that can be
controlled. These are called effec t parameters,
adjusted with the parameter knobs 1 – 4 on the
panel. When thinking of an effect module as a
compact effect, the parameters change t he tone and
effect intensity similar to the knobs on the d evice.

■ Patch

In the B9.1ut, effect module combinations are stored
and called up in units referred to as patch es. A patch
comprises information about the on/off stat us of
each effect module, about the effect type used in
each module, and about effect parameter setti ngs.
Expression pedal settings and tempo set tings are
also stored for each patch individually.

■ Bank and group

Patches are organized in the user group ( U) which
can be modifi ed, and in the preset group (P) which is
read-only. Since each group comprises 80 patches,
there are a total of 160 patches. In the B9.1ut,
patches are called up four at a time and select ed
with the four foot switches. These four patches are
together referred to as a bank. There are 2 0 banks in
a group, numbered 0 – 9 and A – J.

■ Modes

The B9.1ut has five different operation modes, as
listed below.
• Manual mode
In this mode, you play your instrument while using
a specifi c patch and turning modules in that patch
on and off with the foot switches.
This is the default mode of the B9.1ut that is
always active when power is turned on.
• Play mode
In this mode, different patches can be selecte d
quickly using the foot switches.
• Edit mode
In this mode, the effect parameters of a patch c an
be edited (changed).
• Store mode
This mode serves for storing edited patches. It also
allows changing the store positions of patches.
• Bypass/mute mode
When the B9.1ut is in the bypass condition, effect
processing is temporarily tur ned off and only the
original sound is heard. In the mute mode, a ll
sound is turned off. The tuner can be us ed in either
condition.
