ZOOM 504 II

ACOUSTIC

About power

• 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.

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

Battery operation

• Use four IEC R6 (size AA) 1.5 V batteries (alkaline/manganese).

• The 504 II cannot be used for recharging. Pay close attention to the labelling of the battery to make sure you choose the correct type.

• If the 504 II 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.

Environment

Avoid using your 504 II in environments where it will be exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

Handling

• The 504 II 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 can 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.

Alterations

Never open the case of the 504 II or attempt to modify the product in any way since this can result in damage to the unit.

The 504 II is a sophisticated multi effect processor for acoustic or electric guitar with the following features and functions:

• Rich effect palette for acoustic guitar

The 504 II incorporates a wealth of effects specially designed for use with an acoustic guitar. De-AMP reduces harshness when playing an acoustic guitar through a guitar amplifier. AIR lends a spacious feeling to the sound. TOUCH makes picking more uniform and smooth. The 504 II is also useful as a preamplifier for recording acoustic or electric guitar, and it offers various patches tuned specially for electric guitar.

• Great for electric guitar too

The built-in simulator transforms the sound of an electric guitar into that of an acoustic instrument. During a live performance, this makes it a snap to switch between different sound characteristics.

• Highly effective feedback suppressor

The F.B.SUPPRESSOR function automatically detects the frequencies where feedback (howling) occurs and attenuates that band. Operation can be controlled easily with a foot switch.

• Built-in auto-chromatic tuner

The integrated tuning function 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 detecting the feedback frequency, and the expression pedal allows adjusting the volume or effect tone in real time.

• Improved successor to 504

While inheriting the sound characteristics of the very successful ZOOM model 504, the 504 II is even more compact and carries a lower price tag. What's more, it incorporates the world's first wah effect specifically designed for acoustic guitar, plus several other novel effects such as the EMPHASIZER which duplicates the characteristic sound of a resonator.

1. Turn the 504 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.

3. Close the cover of the battery compartment.

Close the cover of the battery compartment.

Push the cover in until the latch audibly snaps into place.

Terms Used in This Manual

Terms Used in This Manual / Using the unit on batteries

Use four IEC R6 (size AA) batteries. When the batteries are getting low, a dot (.) in the bottom section of the display starts to flash.

NOTE

While not using the 504 II, you should disconnect the cable plugged into the INPUT jack, to prevent draining the batteries.

Play mode/edit mode

The internal status of the 504 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.

Global parameters

Normally, effect parameter settings are stored individually for each patch, but some effect parameters affect all patches. Such parameters are called global parameters. The global parameter settings do not change also when the patch is switched.

This section explains some important terms that are used throughout the 504 II documentation.

Effect parameter

The effects of the 504 II consist of a succession of modules that determine the sound. These individual modules are called the effect parameters. As shown in the following illustration, the 504 II has 10 different effect parameters. Changing the setting of an effect parameter is like turning the control knob on a compact effect, leading to a change in the sound.

Effect type

Some effect parameters comprise several different effects which are referred to as effect types. For example, the DLY&REV parameter has the four effect types LARGE, SMALL, DELAY, and DLY+REV. Only one of these can be selected at a time.

Patch

In the 504 II, effects are stored and called up in units referred to as patches. A patch comprises information about the setting and on/off status of effect parameters. The memory of the 504 II holds up to 36 patches.

Bank

A group of six patches is called a bank. The 504 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 504 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.
