Features

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.

Environment

Terms Used in This Manual
This section explains some important terms that are used throughout the 506 II documentation. 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.

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. 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.
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.

Play the open string you want to tune, and watch the display.
The left side of the display shows the note which is closest to the current pitch.
The right side of the display shows a symbol that indicates by how much the tuning is off.

Pitch is high

Pitch is correct

Pitch is low

Tune the other strings in the same way.
Indication turns faster the more the pitch is off.

Editing a Patch

The patches of the 506 II can be freely edited by changing the effect parameter settings. Try editing the currently selected patch to create your own sound.
Change the parameter value

Use the [+]/[-] keys.

Holding down one of these keys will continuously change the value. Additionally pressing the opposite key will cause a faster change. Pressing both keys simultaneously skips to the first value of the next effect type in the same effect module.
Select the effect parameter
Use the [PLAY/EDIT] selector to select the effect you want to change.
The value of the currently selected parameter is shown on the display. (When the 506 II is in edit mode, a dot (.) is shown in the bottom right section of the display.)

To terminate the edit mode and return to the play mode, set the [PLAY/EDIT] selector to the "PLAY" position.

Unless you store the edited patch in memory, the settings you made will be lost when you select a different patch after returning to the play mode. Do not forget to store an edited patch that you wish to keep, as described on page 14.

Storing/Copying Patches

An edited patch can be stored at any desired location in the internal memory of the unit. It is also possible to copy an existing patch and store it at another location.
Press the STORE key in play mode or edit mode.
The bank and patch number on the display are flashing.
Press the STORE key once more.
When the store/copy process is completed, the unit reverts to the original mode, with the target patch being selected.
Use the [ ]/[ ] foot switches to select the target location in which to store the patch.
When the store/copy process is executed, the previous content of the store target is overwritten and cannot be restored if it was a usercreated patch. You should therefore take care when selecting a target patch. However, the factory default settings of an individual patch or all patches can be restored, as described on page 19.
When storing or copying a patch, it is not possible to use the [+]/[-] keys to switch only the bank number.
To cancel the store/copy process
Press the [-] key instead of the STORE key.
The store process is aborted and the unit reverts to the previous mode.
The store process is also canceled when [PLAY/EDIT] selector is operated instead of the [-] key.
Changing the "Patch Call" Method
In normal operation, the sound of the 506 II will change immediately if a patch is selected in play mode. This may be undesirable if a patch from a distant memory location is called and the sound of other unwanted patches in between is heard. If desired, you can change the "Patch call" method from direct selection to the pre-select method. In pre-select mode, you first specify the desired patch and then confirm the selection. The sound will only change after you have confirmed the operation.

Confirm the patch change

When the desired patch is shown, press the [ ]/[ ] foot switches together.
Changing the "Patch call" method to pre-select
To change the "Patch call" method to preselect, you must turn the unit on while holding down the [ ] foot switch.

Confirm

Specifying the desired patch
Use the [ ]/[ ] foot switches to select the patch you want to use next.
You can also use the [+]/[-] keys to only switch the bank.
The patch change is confirmed, the sound changes, and the display stops flashing and stays constantly lit.

Changing the "Patch call" method back to direct select
To change the "Patch call" method back to normal direct select operation, simply turn the unit off and back on again.
This will return the patch select method to the default setting.
The bank and patch number of the patch to be used next will be shown on the display, but the sound does not yet change.

Using the Optional Pedal

The 506 II is equipped with a CONTROL IN jack designed for connection of an optional foot switch or expression pedal. This section explains how to use these accessories.
Restoring Factory Defaults
The 506 II comes with 36 preprogrammed patches. These factory default patches can be restored also if they were overwritten by patches created by the user. There are two ways of restoring factory defaults. "All Initialize" returns the entire set of patches to the original condition. "Factory Recall" restores a specific patch to the original condition. 1. While holding down the STORE key, plug the appropriate cable into the INPUT jack (or DC 9V jack). The indication "AL" flashes on the display.
Using the foot switch (FS01)
Connecting the optional foot switch FS01 to the CONTROL IN jack allows changing banks with the foot switch while the unit is in play mode. (Operating the foot switch in play mode has the same effect as pressing the [+] key.) 1. Plug the cable from the FS01 into the CONTROL IN jack, and then plug the appropriate cable into the INPUT jack (or DC 9V jack). 2. Press the foot switch. With each push of the foot switch, the bank is switched up. Using the Optional Pedal
To perform All Initialize
2. Press the STORE key once more. All patch settings are returned to the factory default condition, and the unit switches to play mode. To cancel All Initialize, press the [-] key.
Using the expression pedal (FP01/FP02)
Connecting an expression pedal (FP01/FP02) to the CONTROL IN jack allows adjusting the volume or an effect parameter in real time. For information on parameters that can be adjusted with the expression pedal, please refer to pages 22 - 29. 1. Plug the cable from the expression pedal into the CONTROL IN jack, and then plug the appropriate cable into the INPUT jack (or DC 9V jack). 2. Select the patch in play mode, and move the expression pedal back and forth. Depending on the program content of the patch, the volume or effect parameter will change.

All user-created patches will be lost when performing All Initialize. Use this function with care.
To perform Factory Recall
2. Use the [ ]/[ ] foot switches to select the patch you want to return to the original condition. The specified bank and patch number are flashing on the display.
During Factory Recall, the [+]/[-] keys cannot be used to switch the bank only. 3. Press the STORE key once more. The settings of the specified patch are returned to the factory default condition. If desired, repeat steps 2 and 3 to restore other patches. To terminate the Factory Recall operation, press the [-] key. The unit will switch to the play mode at this point.
If the foot switch or expression pedal is connected to the 506 II while the unit is powered, malfunction may occur. Be sure to plug the foot switch or expression pedal into the CONTROL IN jack first and then plug the appropriate cable into the INPUT jack (or DC 9V jack). The pedal is active also in edit mode.

Linking Effects

The patches of the 506 II consist of seven serially linked effect modules, as shown in the illustration below. (The maximum number of effects that can be used simultaneously is 8.) You can use all effect modules or selectively set certain modules to on or off.

GAIN (Gain)

-(Off indication)

The function of this parameter depends on the effect type selected for the DIST module. When a clean type effect such as C1 or bE or an enhancer effect is selected Higher setting values emphasize the outline of the sound. When a distortion effect such as dr or FU is selected Higher setting values result in stronger distortion.

Turns the EQ module off.

CONTOUR
EQ module extended parameters
These parameters serve to adjust the effect operation for the effect type selected with the EQ module basic parameters.
PEDAL DIST (Pedal Distortion)
Using the expression pedal connected to the CONTROL IN jack, the GAIN value (1 - 30) can be controlled.

CONTOUR (Contour)

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.) ZOOM 506 II BASS

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.

dE-(Off indication)

DELAY TIME (Delay Time)
(When DELAY or ECHO is selected as effect type) Sets the delay time in the range from 1 - 37. The actual delay time is the setting value x 10 (ms). (Example: A setting of "15" results in a delay time of 150 ms.)

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.
REVERB TIME (Reverb Time)
(When HALL or ROOM is selected as effect type) Sets the reverb time in the range from 1 - 10. Higher right-digit setting values result in longer reverb time.
