The 506 II is a sophisticated multi effect processor for bass guitar
with the following features and functions:
Top level performance
While similar in price to a compact effect device, the 506 II
incorporates a varied palette of 33 effects. Up to eight effects
(including ZNR and amp simulator) can be combined in a patch.
The memory of the unit holds 36 rewritable patches, providing noholds-barred performance.
Intuitive user interface
The user interface has been thoroughly redesigned. Large switches
and keys and a rotary selector make the unit extremely simple to
operate. Any desired effect can be called up swiftly and without fuss.
Great bass effects
The 506 II includes a number of unique effects designed specially
for bass players, such as the innovative bass synthesizer and the
"cry" effect that simulates a talking modulator. This makes it a snap
to create your own original sound.
Built-in auto-chromatic tuner
The integrated tuning function for bass lets you quickly and
precisely tune your instrument on stage.
Dual power supply enables operation anywhere
The dual power supply principle allows the unit to be powered
either from an AC adapter or from four IEC R6 (size AA) batteries.
Continuous operation time on batteries is 8 hours with manganese
batteries and 28 hours with alkaline batteries.
Compatible with foot switch and pedals
An optional foot switch (FS01) or expression pedal (FP01/FP02)
can be connected to the CONTROL IN jack. The foot switch is
useful for quickly switching patches, and the expression pedal can
serve to adjust the volume or effect tone in real time.
Improved successor to 506
While inheriting the sound characteristics of the very successful
ZOOM model 506, the 506 II is even more compact and carries a
lower price tag. And what's more, it incorporates nine new effects,
including bass distortion effects using sophisticated modeling
techniques, practical stage-use and special effects.

Effect type
Within each effect module, there are several different effects which are
referred to as effect types. For example, the modulation effect module
(MOD) comprises chorus, flanger, pitch shifter, and other effect types. Only
one of these can be selected at a time. An effect type is also often simply
referred to as an effect.
Effect parameter
All effect modules have various parameters that can be adjusted. When
likening an effect module to a compact effect device, the parameters can be
thought of as the control knobs on the device. Changing the parameter
settings will result in changes to items such as effect intensity and tonal
characteristics.

Play mode/edit mode
The internal status of the 506 II 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 [PLAY/EDIT] selector serves for switching between the
play mode and edit mode.
Using the unit on batteries
1. Turn the 506 II over and open
the cover of the battery
compartment on the bottom.
Press the latch to release it and
then raise the cover.
2. Insert four fresh IEC R6
(size AA) batteries into the
battery compartment.
Insert all batteries with
the same orientation.
Patch
In the 506 II, 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 memory of the 506 II can store up to
36 patches.
Bank
A group of six patches is called a bank. The 506 II manages a total of six
banks, labelled A through F. The patches within each bank are numbered 1
through 6. To specify a patch, the 506 II uses the following format: "A1".
This means that patch number 1 from bank A is selected. Therefore "b6"
would refer to patch 6 from bank b.

Effect module
As shown in the illustration below, the 506 II can be thought of as a
combination of several single effects. Each such effect is referred to as an
effect module. In addition to modules comprising compressor effects
(COMP) or distortion effects (DIST), the 506 II also provides a module for
ZNR (ZOOM Noise Reduction) and an amp simulator. Parameters such as
effect intensity can be adjusted for each module individually, and modules
can be switched on and off as desired.

LEVEL
This effect mixes a phase-shifted
component to the original sound,
resulting in a pulsating character. Higher
setting values result in faster modulation.
• 4 BAND EQ is selected
Using the 0 value as a reference (flat setting), negative values cause an
increasing boost in the low range and positive values cause an increasing
boost in the high range. When the EQ module is On, this parameter is always
active. Check this parameter if the 4-band EQ effect type setting does not
seem to produce the desired results.
• PHASE SHIFT is selected
Using the 0 value as a reference, changing the value towards negative or
positive makes the phaser effect stronger. (Negative values result in reversed
phase for the effect sound feedback.)

Usage Precautions
• Electrical interference
For safety considerations, the 506 II 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 506 II, as the
possibility of interference cannot be ruled
out entirely.
With any type of digital control device, the
506 II 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 506 II. 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.
