hazard-free use of the GFX-707.

• Power requirements

Warning

• Environment

Caution

This symbol indicates explanations
about extremely dangerous matters. If
users ignore this symbol and handle the
device the wrong way, serious injury or

death could result.
This symbol indicates explanations
about dangerous matters. If users
ignore this symbol and handle the
device the wrong way, bodily injury and
damage to the equipment could result.

Since power consumption of this unit is fairly high, we
recommend the use of an AC adapter whenever possible.
When powering the unit from a battery, use only an alkaline
type.

[AC adapter operation]

• Be sure to use only an AC adapter which supplies 9 V
DC, 300 mA and is equipped with a «center minus» plug
(Zoom AD-0006). The use of an adapter other than the
specified type may damage the unit and pose a safety
hazard.

• Connect the AC adapter only to an AC outlet that supplies
the rated voltage required by the adapter.

• When disconnecting the AC adapter from the AC outlet,
always grasp the adapter itself and do not pull at the
cable.

• When not using the unit for an extended period,
disconnect the AC adapter from the AC outlet.

[Battery operation]

• Use four conventional IEC R6 (size AA) batteries
(alkaline).

• The GFX-707 cannot be used for recharging.
Pay close attention to the labelling of the battery to make
sure you choose the correct type.

• When not using the unit for an extended period, remove
the batteries from the unit.

• If battery leakage has occurred, wipe the battery
compartment and the battery terminals carefully to
remove all remnants of battery fluid.

• While using the unit, the battery compartment cover
should be closed.

Avoid using your GFX-707 in environments where it will be
exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

• Handling

Since the GFX-707 is a precision electronic device, avoid
applying excessive force to the switches and buttons. Also

Caution

take care not to drop the unit, and do not subject it to shock
or excessive pressure.

• Alterations

Never open the case of the GFX-707 or attempt to modify
the product in any way since this can result in damage to the

Caution

unit.

• Connecting cables and input and output
jacks

You should always turn off the power to the GFX-707 and
all other equipment before connecting or disconnecting any

Caution

cables. Also make sure to disconnect all cables and the AC
adapter before moving the GFX-707.

Usage Precautions

• Electrical interference

For safety considerations, the GFX-707 has been designed to
provide maximum protection against the emission of
electromagnetic radiation from inside the device, and protection
from external interference. However, equipment that is very
susceptible to interference or that emits powerful electromagnetic
waves should not be placed near the GFX-707, as the possibility of
interference cannot be ruled out entirely.

With any type of digital control device, the GFX-707 included,
electromagnetic interference can cause malfunctioning and can
corrupt or destroy data. Care should be taken to minimize the risk
of damage.

• Cleaning

Use a soft, dry cloth to clean the GFX-707. If necessary, slightly
moisten the cloth. Do not use abrasive cleanser, wax, or solvents
(such as paint thinner or cleaning alcohol), since these may dull
the finish or damage the surface.

Please keep this manual in a convenient place for future
reference.

ZOOM GFX-707

Introduction

Thank you for selecting the ZOOM GFX-707 (hereafter simply called the «GFX-707«). The
GFX-707 is a sophisticated multi-effect device with the following features and functions:

• Large variety of built-in effects

Four separate effect modules (single/combined effects) can be used at the same time, together with
ZNR (Zoom Noise Reduction) and the built-in amp simulator. Effects include analog distortion,
various modulation effects such as chorus and flanger, and reverberation effects such as reverb and
delay. In total, you have a choice of 48 types of effects.

• 60 immediately usable patches

A combination of effect modules and parameter settings stored in memory is called a «patch». The
GFX-707 has room for 30 patches that are read-only and 30 that can be freely modified by the user.
So you have a total of 60 patches readily available. Patches are organized in banks (A — F, 0 — 5),
each with five patches. It is even possible to assign a distinctive name of up to 6 characters to each
patch.

• Designed for use on stage

The GFX-707 will operate continuously for up to 14 hours on one set of alkaline batteries. The large
display showing patch names is easy to read at a distance, and the built-in expression pedal is great
for enhancing any performance. For extended use, the unit can also be powered by an AC adapter.

Introduction

• Rotary knobs allow speedy parameter editing

When editing a patch, the three knobs on the top panel let you change parameters with a quick and
direct feel. Even during a performance, fine-tuning an effect is no problem at all. The edited patch
can be stored for later use.

• A first in this class: built-in rhythm section

A high quality PCM sound source creates realistic rhythm patterns that are handy for practicing or
for small jam sessions. You can choose from as many as 45 rhythm patterns.

• 6-second sampler

Another advantage is the integrated sampler with a recording duration of up to six seconds. It even
allows half-speed playback without altering the pitch. This feature comes in handy when copying
phrases.

• Jam Play

With a simple foot switch operation, you can record and play a phrase of up to 2 seconds during a
gig. This is great for creating scratch effects such as used by DJs, doing reverse playback or
producing other special effects.

• Integrated amp simulator

Simulates the cabinet sound of a guitar amplifier for a dynamic sound also when sending the line
output to a mixer or recorder.

Please take the time to read this manual carefully, in order to get the most out of your GFX707 and to ensure optimum performance and reliability.

Altering an effect with the pedal

Selecting the effect sound (patch)

A collection of effect modules, each with
distinct parameter settings, is called a patch.
The GFX-707 has memory capacity for 60
patches which are immediately available for
use. These are divided into two groups of 30
patches each. The PRESET group comprises
read-only patches that cannot be changed by
the user. The USER group contains read-andwrite patches that can be freely overwritten by
the user.
Each patch is given a patch name of up to 6
characters, and patches are organized in
banks (A — F, 0 — 5) and patch numbers (1 — 5).

[ Patches, groups and banks ]

To alter an effect in real time, move the
expression pedal while playing your
instrument with the GFX-707 in play mode.

The aspect of the patch that is changed by the
expression pedal can be programmed for each
patch. To get a feel for this, select various patches
and try out the pedal to see what it does.

Push the expression pedal fully down

The expression pedal also incorporates a pushdown switch that allows on/off control of a preset
effect. The effect that is switched by the push-down
switch can be programmed for each patch.
