Warning

Operation using an AC adapter

Use only a ZOOM AD-16 AC adapter with this unit.
Do not use do anything that could exceed the ratings of outlets and other electrical wiring equipment. Before using the equipment in a foreign country or other region where the electrical voltage differs from that indicated on the AC adapter, always consult with a shop that carries ZOOM products beforehand and use the appropriate AC adapter.

Operation using batteries

Use 4 conventional 1.5-volt AA batteries (alkaline or nickel-metal hydride).
Read battery warning labels carefully.
Always close the battery compartment cover when using the unit.

Alterations

Never open the case or attempt to modify the product.

Precautions

Product handling

1 Do not drop, bump or apply excessive force to the unit.
1 Be careful not to allow foreign objects or liquids to enter the unit.

Operating environment

Do not use in extremely high or low temperatures.
Do not use near heaters, stoves and other heat sources.
Do not use in very high humidity or near splashing water.
Do not use in places with excessive vibrations.
Do not use in places with excessive dust or sand.

AC adapter handling

When disconnecting the AC adapter from an outlet, always pull the body of the adapter itself.
During lightning storms or when not using the unit for a long time, disconnect the power plug from the AC outlet.

Battery handling

Install the batteries with the correct + / - orientation.
Use a specified battery type. Do not mix new and old batteries or different brands or types at the same time. When not using the unit for an extended period of time, remove the batteries from the unit.
If a battery leak should occur, wipe the battery compartment and the battery terminals carefully to remove all battery residue.

Connecting cables with input and output jacks

Always turn the power OFF for all equipment before connecting any cables.
Always disconnect all connection cables and the AC adapter before moving the unit.

Volume

Do not use the product at a loud volume for a long time.

Usage Precautions

Interference with other electrical equipment

In consideration of safety, the A3 has been designed to minimize the emission of electromagnetic radiation from the device and to minimize external electromagnetic interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves could result in interference if placed nearby. If this occurs, place the A3 and the other device farther apart. With any type of electronic device that uses digital control, including the A3, electromagnetic interference could cause malfunction, corrupt or destroy data and result in other unexpected trouble. Always use caution.

Cleaning

Use a soft cloth to clean the panels of the unit if they become dirty. If necessary, use a damp cloth that has been wrung out well. Never use abrasive cleansers, wax or solvents, including alcohol, benzene and paint thinner.

Malfunction

If the unit becomes broken or malfunctions, immediately disconnect the AC adapter, turn the power OFF and disconnect other cables. Contact the store where you bought the unit or ZOOM service with the following information: product model, serial number and specific symptoms of failure or malfunction, along with your name, address and telephone number.

Acoustic modeling restores body tone

Presents for 16 body types and 28 model types simulate the sonic characteristics of a variety of acoustic guitars with different body shapes and material properties. By choosing a body and model according to the guitar that you are using, you can share the original rich and beautiful tone of your acoustic guitar with audiences when you perform live.

High-quality preamp can be used with both pickups and mics

The preamp was designed especially for acoustic guitars and can be used with piezoelectric, magnetic and passive pickups. In addition, you can connect a condenser microphone to the XLR mic input, which can provide phantom power, and mix that signal with the pickup signal to shape the sound. This acoustic guitar preamp offers a full array of features. The 3-band EQ can be used to adjust the tone according to the environment. The BALANCE knob can be used to set the ratio of the original sound (DRY) and the sound after the effects (WET). The super low noise design provides a 120dB S/N ratio and a -100dBm noise floor.

40 types of acoustic guitar effects

The 40 effects, which have a focus on chorus, delay, reverb and other spatial effects, can make acoustic tones even more beautiful. Other effects include a compressor that suppresses input peaks and evens the volume level, an air effect that simulates the sense of space from room tone and a detuning effect that creates a sound like a 12-string guitar. You can use any 2 of these effects together as you like.

Anti-feedback function with minimal effect on tone quality

The Anti-feedback function can quickly and effectively eliminate feedback during a performance. Just step on the Anti-feedback switch to automatically detect the frequency that is causing feedback and surgically apply a steep filter to cut that frequency band. The Anti-feedback function can handle up to 3 different frequencies that are causing feedback.

Clean boost of up to 12 dB

The Boost function can reduce the volume differences of fingerpicking, strumming chords and other guitar playing techniques, as well as increase amplification during solos. You can also adjust the sound when the boost is active with the TONE parameter.

Terms Used in This Manual

The unit will not turn ON

• Confirm that the POWER switch is set to "ON". When using bus power, set the switch to "OFF" before connecting the USB cable.
• When using batteries, confirm that they still have a charge.

No sound or very low volume

• Check the connections ( P4 - 5)
• Adjust input sensitivity ( P8)
• Adjust the master level ( P9)
• Confirm that unit is not in mute mode ( P24)
• If using a condenser mic, confirm that phantom power is ON ( P23)

There is a lot of noise

• Check shielded cables for defects.
• Use only a genuine ZOOM AC adapter.

The sound distorts strangely/has an odd timbre

• Adjust input sensitivity ( P8)
• Adjust the master level ( P9)
• Adjust the amount of boost amplification ( P15)
• Set the pickup selection correctly for the type of pickup. ( P5)

An effect is not working

• Adjust the balance knob ( P9) .
• If the effect processing capacity is exceeded, "THRU" appears on the effect graphic. In this case, the effect is bypassed ( P11)

Batteries lose their charge quickly

• Confirm that you are not using manganese batteries. Alkaline batteries should provide 8 hours of continuous operation.
• Check the battery setting ( P25) . Set the type of batter being used to enable the remaining charge to be shown more accurately.
• Confirm that phantom power is not being used. When +48V phantom power is being used, the unit can operate continuously for about 5 hours with alkaline batteries.
