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.
