USAGE AND SAFETY PRECAUTIONS

In this manual, symbols are used to highlight warnings and cautions for you to read so that accidents can be prevented. The meanings of these symbols are as follows:

Please observe the following safety tips and precautions to ensure hazard-free use of the 508.

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 the cable.

• If the unit is not to be used for a long time, disconnect the AC adapter from the outlet.

Battery operation

• Use only a 9 V (alkaline) battery (6LR61).

• The 508 cannot be used for recharging. Pay close attention to the labelling of the battery to make sure you choose the correct type.

• If the 508 is not to be used for an extended period of time, remove the battery 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 508 in environments where it will be exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

• The 508 is a precision instrument. Except for the foot switches, do not push other parts with your feet or subject them to strong force.

• Take care that no foreign objects (coins or pins etc.) or liquids enter the unit.

• Be sure to turn the power to all equipment off before making connections.

• Before moving the unit, turn the power off and disconnect all cables and the AC adapter.

Never open the case of the 508 or attempt to modify the product in any way since this can result in damage to the unit.

Usage precautions

For safety considerations, the 508 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and from external interference.However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the 508, as the possibility of interference cannot be ruled out entirely.

Whatever the type of digital control device, the 508 included, electromagnetic damage can cause malfunctioning and corrupt or destroy data. Since this is an ever-present danger, thorough care should be taken to minimize the risk of damage.

Use a soft, dry cloth to clean the 508. 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.

Connecting cables and input and output jacks

You should always turn off the power to the 508 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all cables and the AC adapter before moving the 508.

Operation Manual

• PATCH

A group of the settings for a certain effect type is called a PATCH. The 508 comes with 24 preset patches which can be changed (edited) by the user.

• BANK

The 508 calls up patches in sets of four, called a "bank".

The 508 has memory capacity for 24 patches. At the factory, these are programmed with recommended settings. The user can freely change the contents of any patch, and it is also possible to restore the factory settings.

Seamless Function

Controls, Functions and Connections

With conventional delay and multi-effect units, the sound cuts off unnaturally when patches are switched.

For example, when switching from a solo performance using a long delay to a patch with a short delay for backing, the delay of the previous patch stops abruptly the instant before the next patch starts, causing the reverberation to sound unnatural. This type of problem experienced by guitarists is solved by the 508's revolutionary seamless function. This function holds the delay sound of the previous patch after it has been switched, so that the transition from one patch to the next is performed smoothly.

The seamless function can be used in two ways. One method is to leave the time for the delay sound as it is set in the patch. The other method is to force the delay sound to decrease at the timing decided by the seamless function. It is not necessarily preferable to leave the seamless function on normally. Rather, it should be switched on and off to suit the musical circumstances under which patches are switched. (The on/off status of the seamless function can be stored for each patch.)

By combining the seamless and hold functions, you can perform solo by using new patches while holding the riff and rhythm pattern (repeat playback). For details, see [12. Effect Parameters] .

TUNER indicator

In the 508, this indicator shows that the tuner is active, and it serves as a gauge for fine tuning your instrument.

• BATTERY EMPTY WARNING display

When the unit is powered from the battery, this indicator begins flashing to warn that the battery is running low.

STORE key

When the contents of patches are to be stored, this key is used for putting the unit in store standby status and to execute the store function.

• Setting of direct load function

When the STORE key is pressed for at least 1 second during Play mode (during performance), the direct load function can be switched on or off. [For details, see 10. Patch Switching (Application: Direct Load OFF).]

EDIT key (for creating your own patches)

This key serves to toggle between the Play mode and Edit mode (mode for creating patches to suit your taste). In Edit mode, this key can be used to select the effect parameters you wish to change. Also, when the effect parameter HOLD/TAP is selected, press this EDIT key to return from the Edit mode to the Play mode.

• Setting of bank hold function

When the EDIT key is held down for at least 1 second in Play mode, the bank hold function is turned on or off. [For details, see 9. Patch Switching (Application: Bank Hold ON).]

INPUT jack

Serves for connecting the guitar. When the unit is powered by the battery, this jack also functions as the power on/off switch. The 508 is powered on by plugging a shielded cable into this jack. When the unit is not in use, the cable should be disconnected to prevent battery drain.
