Contents

Thank you for selecting the ZOOM Player Pro 4040 (hereafter simply called the “4040”).

The 4040 is a sophisticated multi-effect device with the following features and functions:

• A total of 25 built-in individual effects, which can be combined in patches of
up to six effects. 40 preset patches and a user memory for 40 additional
patches offer extraordinary flexibility.

• Integrated volume and expression pedals allow adjustment of output level and
effect settings in real time. This is ideal for use during a live performance.

• Integrated auto-chromatic guitar tuning function lets you quickly and
precisely tune instruments on stage.

• Compression and distortion effects are generated using analog circuitry, to
assure rich and natural-sounding sustain and distortion.

• Send/return Jacks allow connection of external effect devices, and a control
out lets you switch guitar amp channels. You can even program the use of
these connectors as part of a patch, to create sophisticated sound effects.

• MIDI OUT for control of external MIDI devices makes the 4040 convenient as
a system control center.

• By using the optional foot switch FS01, single effect on/off switching during a
performance is possible, for further enhanced playability.

Please take the time to read this manual carefully, in order to get the most out of your 4040 and to
ensure optimum performance and reliability.

1

Safety Precautions

Please observe the following safety tips and precautions to
ensure hazard-free use of the 4040.

• Power requirements

The 4040 is powered by the supplied AC adapter
AD0003/AD0004. To prevent malfunction and safety
hazands, Do not use any other kind of AC adapter.

When using the 4040 in an area with a different line
voltage, please consult your local ZOOM distributor about
acquiring a proper AC adapter.

• Environment

Avoid using your 4040 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 4040 is a precision electronic device, avoid
applying excessive force to the switches and buttons. Also
take care not to drop the unit, and do not subject it to
shock or excessive pressure.

• Alterations

Never open the case of the 4040 or attempt to modify the
product in any way since this can result in damage to the
unit.

• Connecting cables and input and output jacks

You should always turn off the power to the 4040 and all
other equipment before connecting or disconnecting any
cables. Also make sure to disconnect all cables and the
AC adapter before moving the 4040.

Usage Precautions

• Electrical interference

The 4040 uses digital circuitry that may cause interference
and noise if placed too close to other electrical equipment,
such as TV sets and radio receivers. If such problems
occur, move the 4040 further away from the affected
equipment. Also, when fluorescent lights or devices with
built-in motors are close to the 4040, the unit may not
function properly.

• Cleaning

Use a soft, dry cloth to clean the 4040. 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.

• Effect Module

The 4040 incorporates five types of effect groups which are
referred to as “effect modules”. Each effect module can be
thought of as a single compact effect. The 4040 therefore
operates like five compact effects connected in series. In
addition, it is also possible to connect external effect
devices.
The 4040 offers the following five effect modules:

• PRE (Analog compressor and distortion effects)

• EQ (Equalizer and wah effects, amp simulation)

• MODULATION (Modulation effects for changing
pitch or sound timbre, such as pedal pitch and flanger)

• DELAY (Delay effects)

• REVERB (Reverberation effects)

• Effect Type

Each effect module contains several effect variations which
are called “effect types”. Each effect module can use one
effect type at a time. For a list of effect types in each effect
module, please see the table on page 10.

• Patches and Groups

The 4040 allows you to use a maximum of five effect
modules simultaneously. A combination of effect modules,
each with individual parameter settings plus the final output
level setting is referred to as a “patch”. The patch also
includes the external effect on/off setting, external control
setting, and expression pedal setting.

The 4040 has two memory areas or “groups” where patches
are stored: the USER group for patches that can be freely
altered and stored by the user, and the PRESET group for
factory defined read-only patches. There are 40 patches in
each group, for a total of 80 patches.

• Bank

The 4040 calls up patches in sets of four, and the foot pedals

serve to switch between patches. Such a set of four patches
is referred to as a “bank”. To select a patch, first specify the
group and the bank number (0 – 9), and then use the foot
pedal switches 1 – 4 to select the patch number.

• Parameter

The elements which determine the sound of an effect are
referred to as “parameters”. Parameter values can be
adjusted for each effect module, to create your own patches
with the 4040.

• Mode

The functions of the 4040 can be roughly divided into three
different categories. These are called “modes”, as described
below.

• Play Mode

In this mode, patches can be selected and played. This is
the default mode of the 4040 when power is turned on.

• Edit (Manual) Mode

In this mode, the parameters of each patch can be edited.
The mode can also serve as a manual mode to switch
effect modules on and off during a performance using the
pedal switches 1 – 4 and the BANK ▼ pedal.

• Special Mode

Serves to return some or all patch data to the factory
preset condition.

• Select the bank with the BANK pedals.

A bank is a group of four patches. There are ten banks each
(numbered 0 through 9) for the USER group and the
PRESET group. The BANK ▲ pedal selects the next higher
bank, and the BANK ▼ pedal the next lower bank. (The
bank number display flashes.)

Merely pressing one of the BANK pedals does not
yet change the patch. To activate the patch and
change the sound, press one of the pedal switches 1 ­4, as described below.

• Select the patch by pressing one of the pedal switches
1 – 4.

The LED of that pedal lights up, showing that the patch has
been selected. (The BANK number is now constantly lit.)

Now would be a good time to try out some of the various
patches offered by the 4040 while playing your instrument.

Useful functions in the Play mode

Some other useful functions available in Play mode are
described below.

■ Adjusting the patch level

The final output level of the patch — called the patch level
— is also stored as a parameter along with the other
parameters of the patch. In the Play mode, the patch level
can be adjusted.

• Press the VALUE + / - keys in the Play mode.

When one of the VALUE + / - keys is pressed, the current
patch level setting is shown on the display as a numeric
value (0 – 50). Pressing VALUE + increases the value and
pressing VALUE - decreases it. To change values
continuously, hold down the key. To change values more
rapidly, press the other key as well.

The patch level setting change made in this way is
only temporary. If you select a different patch
without storing the new level setting first, the setting
will be lost. (For details on how to store settings,
please refer to page 12.)

In the Play mode, the patch level can be adjusted
also for patches from the PRESET group, but the
new level setting cannot be stored. When wishing to
store the level, select a patch from the USER group.

■ Bypassing the effects

You can temporarily turn off all effects in a patch. This is
useful for example to check the sonic character of a patch.
The bypass mode is also used for the chromatic tuning
function.

• In the Play mode, press the pedal switch 1 - 4 whose
LED is lit (i.e. the pedal switch that was used to choose
the current patch).

All effects in the patch are now bypassed and the original
instrument sound is heard. In the bypass condition, the LED
of the selected patch flashes and the tuner LED lights up.

• Press the pedal switch once more to turn the patch on
again. Normal Play mode can also be restored by
selecting a different patch.
