ZOOM G9.2tt

Features

Thank you for selecting the

ZOOM G9.2tt

(simply called the "

G9.2tt

" in this manual). The G9.2tt is a

sophisticated Multi Effect Processor with the following features.

●

Latest technology for top performance

Excellent sound quality is assured by signal processing featuring 96 kHz/24 bit sampling and internal 32-bit
processing. Frequency response remains flat to 40 kHz, and input converted noise is an amazing 120 dB or better.

●

Ready-to-use patches

Effect module combinations and settings can be stored and recalled as "patches". The G9.2tt offers 100
patches in the read-only preset groups, plus 100 patches in the user groups which can be freely rewritten,
resulting in a total of 200 choices. Send / return level and on/off settings of external effects connected via
the SEND/RETURN jacks can also be stored as part of a patch.

●

Great for stage work or direct recording

The pre-amp section features two channels, and each distortion type has two dedicated algorithms, one for
live playing and one for direct recording. The CABINET effect simulates amp and mic recording
characteristics, and the algorithm is automatically switched according to the CABINET on/off setting. An
amp select feature matches the sound to the amp you are using. Connecting the G9.2tt to the power amplifier
input of the guitar amp is no problem: simply set the -10 dBm/+4 dBm switch to the +4 dBm position.

●

Built-in tuner supports special tuning requirements

In addition to the standard auto-chromatic tuner, various other tuning methods are possible. The tuner
also allows easy tuning on stage without producing sound.

●

Two expression pedals built in as standard

Adjust effect tone or volume in real time with the two expression pedals that are built right into the unit.
The right-side pedal in particular deserves attention: the Z-Pedal that senses not only vertical but even
horizontal movement. Step into the next dimension of pedal play and discover a whole new world of
possibilities.

●

Tube powered Accelerator and Energizer

The analog input stage features an Accelerator that lets you freely mix the signals amplified by a vacuum tube
circuit and a solid-state circrit. In this way, you can add characteristic tube compression and distortion to a
clean sound. In addition, the G9.2tt also features an Energizer that processes the analog output signal to
produce that characteristic warm and dynamic sound that is the hallmark of a tube amplifier.

●

Programmable function foot switches

Two user-programmable function foot switches further enhance flexibility and let you optimize the unit
for any application. Use them to switch pre-amp channels, set the delay time, turn hold delay on and off,
or for various other tasks.

Please take the time to read this manual carefully, in order to get the most out of your G9.2tt and to ensure
optimum performance and reliability.

Terms Used in This Manual

This section explains some important terms that are used throughout the G9.2tt documentation.

■

Effect module

As shown in the illustration below, the G9.2tt can be
thought of as a combination of several single effects.
Each of these is referred to as an effect module. The
G9.2tt offers a compressor effect module (COMP),
amp simulator/distortion 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 virtual preamplifier 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 types. For
example, the modulation effect module (MOD/
EFX2) comprises chorus, flanger, pitch shifter,
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 effect parameters,
adjusted with the parameter knobs 1 - 4 on the panel.
When thinking of an effect module as a compact
effect, the parameters change the tone and effect
intensity similar to the knobs on the device.

■

Patch

In the G9.2tt, 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.
Expression pedal settings and tempo settings are also
stored for each patch individually.

■

Bank and group

Patches are organized in user groups (U, u) which
can be modified, and in preset groups (A, b)
which are read-only. Since each group comprises

50 patches, groups A, b, U, and u offer a total of
200 patches.

In the G9.2tt, patches are called up five at a time
and selected with the foot switches. These five
patches are together referred to as a bank. There
are ten banks in a group, numbered 0 through 9.

■

Modes

The G9.2tt has five different operation modes, as
listed below.

●

Play mode

In this mode, patches can be selected and played.
This is the default mode of the G9.2tt that is
always active when power is turned on.

●

Manual mode

In this mode, you play your instrument while
using the foot switches to turn modules on and off.

●

Edit mode

In this mode, the effect parameters of a patch can
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 G9.2tt is in the bypass condition, effect
processing is temporarily turned off and only the
original sound is heard. In the mute mode, all
sound is turned off. The built-in tuner can be used
in either condition.
