Features 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. Features Warning Caution Please observe the following safety tips and precautions to ensure hazard-free use of the 504 II. About power Warning · 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. · 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. · 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.

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. ZOOM 504 II ACOUSTIC 2 ZOOM 504 II ACOUSTIC 3 Terms Used in This Manual 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 parameters 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. Terms Used in This Manual Terms Used in This Manual / Using the unit on batteries 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. OUT IN F.B. PATCH TYPE LIMIT/ LOW/ HIGH/ AIR EFFECT DLY& De-AMP EDGE BODY TOP REV SUPPRESSOR LEVEL Global parameters Using the unit on batteries 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. 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. BANK F PATCH 1 PATCH 2 PATCH 3 PATCH 4 PATCH 5 PATCH 6 Insert all batteries with the same orientation.

NOTE (9) = global parameter 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. ZOOM 504 II ACOUSTIC 12 ZOOM 504 II ACOUSTIC 13 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. Storing/Copying Patches 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. Storing/Copying Patches Storing/Copying Patches NOTE Use the [ ]/[ ] foot switches to select the target location in which to store the patch. NOTE 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 21. 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. NOTE The store process is also canceled when [PLAY/EDIT] selector is operated instead of the [-] key. 14 ZOOM 504 II ACOUSTIC ZOOM 504 II ACOUSTIC 15 Changing the "Patch Call" Method In normal operation, the sound of the 504 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. Changing the "Patch Call" Method Confirm the patch change When the desired patch is shown, press the [ ]/[ ] foot switches together. Changing the "Patch Call" Method 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. Changing the "Patch Call" Method 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. 16 ZOOM 504 II ACOUSTIC ZOOM 504 II ACOUSTIC 17 Using the Feedback Suppressor The 504 II incorporates an F.B.SUPPRESSOR that serves for reducing acoustic feedback by cutting a specific frequency range (feedback frequency). The F.B.SUPPRESSOR can be used in play mode or edit mode. 5. If feedback occurs during play, press the FS01 twice. F.B.SUPPRESSOR is switched on/off and the 504 II automatically detects the feedback frequency for attenuation. FS01 Using F.B.SUPPRESSOR in play mode If feedback occurs while playing the instrument, the optional foot switch (FS01) connected to the CONTROL IN jack can be used to automatically detect the feedback frequency. Using F.B.SUPPRESSOR in edit mode The following method allows finding the feedback frequency in edit mode, either automatically or manually. 1. Insert the plug of the FS01 into the CONTROL IN jack of the 504 II, then turn power to the 504 II on. Using the Feedback Suppressor NOTE 1. If feedback occurs while playing the instrument, set the [PLAY/EDIT] selector to "F.B.SUPPRESSOR". The 504 II switches to the edit mode. Using the Feedback Suppressor If the FS01 is plugged into the CONTROL IN jack while the 504 II is already on, malfunction may occur. Be sure to turn on the 504 II only after connecting the foot switch. 2. Set the [PLAY/EDIT] selector to "F.B.SUPPRESSOR". 2. Use the [+]/[-] keys to change the display indication to "SC". If "SC" is already set, change the value and then select "SC" again, or press both [ ]/[ ] foot switches (or the foot switch FS01 connected to the CONTROL IN jack) twice, to switch the F.B.SUPPRESSOR parameter off and then on again. 3. Use the [+]/[-] keys to change the display indication to "SC". "SC" is the attenuation setting value based on automatic detection of feedback frequency. Automatic detection starts when the F.B.SUPPRESSOR parameter is set to "SC" or set to off and then on again. When wishing to retain the "SC" setting also while the unit is turned off, store the currently selected patch. 3. If feedback is not satisfactorily reduced by step 2, set the F.B.SUPPRESSOR parameter to a value between 1 - 30 that yields the best reduction. When wishing to retain the F.B.SUPPRESSOR parameter setting also while the unit is turned off, store the currently selected patch. 4. Return the [PLAY/EDIT] selector to "PLAY". 18 ZOOM 504 II ACOUSTIC ZOOM 504 II ACOUSTIC 19 Using the Expression Pedal (FP01/FP02) The 504 II is equipped with a CONTROL IN jack designed for connection of the optional expression pedal FP01 or FP02. The pedal can be used as volume pedal or as a controller for varying effect parameters. For information on parameters that can be adjusted with the expression pedal, please refer to pages 26 - 29. Restoring Factory Defaults The 504 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. 1. Plug the cable from the FP01/FP02 into the CONTROL IN jack of the 504 II, and then turn the 504 II on. NOTE To perform All Initialize If the FP01/FP02 is plugged into the CONTROL IN jack while the 504 II is already on, malfunction may occur. Be sure to turn on the 504 II only after connecting the expression pedal. 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. Restoring Factory Defaults NOTE Using the Expression Pedal 2. Select the patch in play mode, and move the expression pedal back and forth while playing your Move back and forth instrument. Depending on the program content of the patch, the volume or effect parameter will change. The expression pedal can also be used in edit mode to control the volume or effect parameter. 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. 20 ZOOM 504 II ACOUSTIC ZOOM 504 II ACOUSTIC 21 Linking Effects The patches of the 504 II consist of ten effect parameters (including two global parameters). By setting these parameters to the desired values, you can control the sound of a patch. It is also possible to switch individual parameters on and off, and to program the expression pedal to adjust the value of a specific parameter. Effect parameters Effect Parameters This section describes all parameters and their setting values. How to read the listing [PLAY/EDIT] selector Shows the position which is used to call up the parameter. Display Shows the setting range that is available for that parameter.

EMPHASIZER This effect adds higher harmonics to emphasize the sound character. Higher values result in more dazzling sound. RICH CHORUS Generates a deep, rich sounding chorus. Higher values result in stronger chorus effect. PEDAL EMPHASIZER Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the intensity of the EMPHASIZER effect. PEDAL RICH CHORUS Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the mixing ratio of the RICH CHORUS effect. DRY MIX Mixes the original guitar sound to the signal after passing the AIR parameter. Lower values result in stronger AIR parameter influence and higher values result in stronger original sound. Signal after passing AIR parameter TYPE LIMIT/ EDGE LOW/ BODY HIGH/ TOP AIR Effect Parameters Effect Parameters LIGHT CHORUS Generates a light chorus with soft modulation. Higher values result in stronger chorus effect. PEDAL LIGHT CHORUS Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the mixing ratio of the LIGHT CHORUS effect. Original sound PEDAL DRY MIX Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the mixing balance between the signal after passing the AIR parameter and the original sound. The actual sound that will be produced by this effect depends on the settings made for the various parameters before the AIR parameter. If the sound after the AIR parameter and the original sound is not very different, the effect will be weak. 12-STRING Produces an effect resembling the sound of a 12-string guitar. Larger values result in a stronger effect. PEDAL 12-STRING Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the intensity of the 12-STRING effect. 26 ZOOM 504 II ACOUSTIC ZOOM 504 II ACOUSTIC 27 WAH This is an auto wah effect that works on single notes. Higher values result in stronger auto wah. PEDAL DELAY Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the delay sound mixing balance (delay time will be set to 250 mS). PEDAL WAH Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to manually adjust the WAH effect. When no pedal is used, the parameter functions as auto wah. DELAY+REVERB This is an effect which combines delay (delay time 210 mS) and reverb. Higher values result in deeper reverb effect and higher delay sound mixing ratio. oF Sets the EFFECT parameter to OFF. PEDAL DELAY+REVERB Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the delay sound mixing balance (reverb depth is fixed). DELAY&REVERB Mixes a delayed component and reverb component to the original sound, producing a feeling of depth and ambience. oF Sets the DELAY&REVERB parameter to OFF. LARGE Simulates the reverberation in a fairly large room. Higher values result in a deeper reverb effect. De-AMP This parameter serves for attenuating frequency bands that can sound harsh when an acoustic guitar is reproduced via a guitar amplifier. Choose the BRIGHT COMBO, COMBO, or STACK setting depending on the amplifier that is used, and adjust the value as required. PEDAL LARGE Effect Parameters Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the reverb sound mixing balance. Effect Parameters SMALL Simulates the reverberation in a fairly small room. Higher values result in a deeper reverb effect. BRIGHT COMBO Designed for use with combo type amplifiers having a bright sound. Higher values result in stronger attenuation effect. PEDAL SMALL Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the reverb sound mixing balance. COMBO Designed for use with regular combo type amplifiers. Higher values result in stronger attenuation effect. DELAY This is a delay effect with a delay time of 370 mS maximum. Higher values result in longer delay time (longer delay sound intervals). LEVEL Original sound Delay sound Delay time TIME Value Delay time 1 100ms 2 150ms 3 180ms 4 215ms 5 230ms 6 250ms 7 280ms 8 340ms 9 370ms STACK Designed for use with stack type amplifiers. Higher values result in stronger attenuation effect. oF Sets the De-AMP parameter to OFF. ZOOM 504 II ACOUSTIC
