IMPORTANT NOTES  
Power Supply: Use of Batteries  
Maintenance  
Do not connect this unit to same electrical outlet that is being used  
by an electrical appliance that is controlled by an inverter (such as a  
refrigerator, washing machine, microwave oven, or air conditioner), or  
that contains a motor. Depending on the way in which the electrical  
appliance is used, power supply noise may cause this unit to malfunc-  
tion or may produce audible noise. If it is not practical to use a separate  
electrical outlet, connect a power supply noise filter between this unit  
and the electrical outlet.  
For everyday cleaning wipe the unit with a soft, dry cloth or one that  
has been slightly dampened with water. To remove stubborn dirt, use a  
cloth impregnated with a mild, non-abrasive detergent. Afterwards, be  
sure to wipe the unit thoroughly with a soft, dry cloth.  
Never use benzine, thinners, alcohol or solvents of any kind, to avoid  
the possibility of discoloration and/or deformation.  
Additional Precautions  
The AC adaptor will begin to generate heat after long hours of  
consecutive use. This is normal, and is not a cause for concern.  
Use a reasonable amount of care when using the unit’s buttons, sliders,  
or other controls; and when using its jacks and connectors. Rough  
handling can lead to malfunctions.  
When installing or replacing batteries, always turn off the power on  
this unit and disconnect any other devices you may have connected.  
This way, you can prevent malfunction and/or damage to speakers or  
other devices.  
When connecting / disconnecting all cables, grasp the connector  
itself—never pull on the cable. This way you will avoid causing shorts,  
or damage to the cable’s internal elements.  
Before connecting this unit to other devices, turn off the power to all  
units. This will help prevent malfunctions and/or damage to speakers  
or other devices.  
To avoid disturbing your neighbors, try to keep the unit’s volume at  
reasonable levels. You may prefer to use headphones, so you do not  
need to be concerned about those around you (especially when it is  
late at night).  
Placement  
When you need to transport the unit, package it in the box (including  
padding) that it came in, if possible. Otherwise, you will need to use  
equivalent packaging materials.  
Using the unit near power amplifiers (or other equipment containing  
large power transformers) may induce hum. To alleviate the problem,  
change the orientation of this unit; or move it farther away from the  
source of interference.  
Some connection cables contain resistors. Do not use cables that  
incorporate resistors for connecting to this unit. The use of such cables  
can cause the sound level to be extremely low, or impossible to hear.  
For information on cable specifications, contact the manufacturer of  
the cable.  
This device may interfere with radio and television reception. Do not  
use this device in the vicinity of such receivers.  
Noise may be produced if wireless communications devices, such as  
cell phones, are operated in the vicinity of this unit. Such noise could  
occur when receiving or initiating a call, or while conversing. Should  
you experience such problems, you should relocate such wireless  
devices so they are at a greater distance from this unit, or switch them  
off.  
Copyright

and/or humidity is very different, water droplets (condensation) may  
form inside the unit. Damage or malfunction may result if you attempt  
to use the unit in this condition. Therefore, before using the unit, you  
must allow it to stand for several hours, until the condensation has  
completely evaporated.  
Do not allow rubber, vinyl, or similar materials to remain on the unit for  
long periods of time. Such objects can discolor or otherwise harmfully  
affect the finish.  
Do not paste stickers, decals, or the like to this instrument. Peeling  
such matter off the instrument may damage the exterior finish.  
Depending on the material and temperature of the surface on which  
you place the unit, its rubber feet may discolor or mar the surface.  
You can place a piece of felt or cloth under the rubber feet to prevent  
this from happening. If you do so, please make sure that the unit will  
not slip or move accidentally.

battery case, battery replacement will be easier if you remove the  
battery case.  
4
1. Loosen the screws from these  
two locations.  
2. Remove the battery case.  
* We recommend that you keep batteries installed in the unit even  
though you’ll be powering it with the AC adaptor. That way, you’ll be  
able to continue a performance even if the cord of the AC adaptor  
gets accidently disconnected from the unit.  
* To prevent malfunction and speaker damage, make sure to switch  
off the AC-33’s power before you insert or replace its batteries, and  
before connecting it to other devices.  
* Take care that no metal object touches the contacts of the battery  
case. This can short-circuit the batteries, causing the case to  
overheat or burn.  
About batteries  
Batteries that can be used  
The AC-33 uses eight AA alkaline or nickel-metal hydride batteries.  
* Nickel-metal hydride batteries cannot be recharged by the AC-33  
itself. You’ll need to use a commercially available battery manufac-  
turer.  
* When using nickel-metal hydride batteries, please be aware that the  
battery life will normally shorten each time they are recharged.  
Caution regarding batteries  
Insert the batteries as directed, taking care to observe the correct polarity (+/- orientation).  
Do not mix new and used batteries, or batteries of different types.  
Carefully read and observe the cautions and handling instructions that accompany the batteries.  
When using nickel-metal hydride batteries, you must use the charger that is specified by the battery manufacturer.  
Remove the batteries if you won’t be using the unit for several months.  
If any electrolyte leaks from a battery, use a dry cloth to carefully wipe off any electrolyte that might be on the battery case, and then install new  
batteries. Battery electrolyte that contacts your skin may cause a rash. Battery electrolyte is hazardous to your eyes; if any electrolyte gets into  
your eyes, flush them immediately with water.  
Do not carry or store batteries together with metallic objects such as pens, necklaces, or hairpins.

WIDE  
spacious chorusing that is appropriate for the sound of an  
acoustic guitar.  
The low range remains firmly localized in the center, and the  
sound will become more spacious as you go from the mid to the  
high range.  
This effect adds spatial depth. It produces a broader sound  
field and a sense of presence.  
The position of the knob adjusts the volume and depth of the  
ambience.  
AMBIENCE  
This is a chorus that mixes the sounds in the air, a method that  
is possible only with a stereo system. On the AC-33, the effect  
sound is emitted by the right speaker (as you face the unit), and  
the direct sound is emitted by the left speaker. The chorus effect  
is produced as the sound from the left and right speakers is  
mixed in the air.  
Compared to an electrically mixed chorus effect, this effect  
has a broader left/right spread and a more natural-sounding  
spaciousness.  
REVERB  
AMBIENCE  
SPACE  
OFF  
No chorus effect will be applied.  
The left half of the knob’s range applies reverb, and the right half  
applies ambience.  
Turning the knob toward the right will deepen the effect.  
If you want to turn reverb/ambience off, turn the knob all the way to  
the left.  
Turn the switch off if you don’t want to apply chorus.  
About foot switches  
If you use a foot switch (BOSS FS-5U or FS-6; sold separately) you’ll be able to turn chorus on/off and reverb/ambience on/off with your foot.  
If a foot switch is connected, the pedal(s) will operate as follows.  
Refer to p. 9 for details on the foot switch’s polarity setting.  
If you use a phone plug (mono) cable to connect only one foot switch,  
it will only turn chorus on/off.  
Chorus on/off operations apply in common to the GUITAR CHANNEL  
and the MIC/LINE CHANNEL.

Anti Feedback Function  
1. Turn the [ANTI-FEEDBACK] switch ON.  
Anti Feedback function  
The anti-feedback function will be applied to the  
microphone or guitar connected to the GUITAR  
CHANNEL and MIC/LINE CHANNEL inputs.  
What is acoustic feedback?  
This is an unpleasant oscillation (a whine, buzz, or howl) that occurs  
when the output from a speaker is re-input to a microphone or pickup,  
amplified, and output again from the speaker.  
MEMO  
In order to prevent feedback from occurring during your performance,  
we recommend that you turn the anti-feedback function on before  
you begin performing.  
This is more likely to occur when you point the microphone at a  
speaker or raise the volume to a high level.  
NOTE  
Sound continues  
cycling, causing  
feedback  
The anti-feedback function will be reset when you turn the power off,  
then on again.  
* If the anti-feedback function is not enough to suppress feedback,  
take the following steps  
Change the direction of the guitar or microphone  
Move the guitar or microphone away from the speakers  
Lower the volume  
Using the Anti Feedback function  
What is the anti-feedback function?  
This function suppresses the acoustic feedback that can occur  
between a guitar or microphone and the amp. It does this by attenuat-  
ing the sound in the frequency range at which feedback is occurring.  
Feedback will be suppressed automatically when you use the  
anti-feedback function.
