PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep these precautions in a safe place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock,
short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:

• Do not open the instrument or attempt to disassemble the internal parts or modify them in any
way. The instrument contains no user-serviceable parts. If it should appear to be malfunctioning,
discontinue use immediately and have it inspected by qualified Yamaha service personnel.

• Do not expose the instrument to rain, use it near water or in damp or wet conditions, or place
containers on it containing liquids which might spill into any openings.

• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a sudden loss of sound
during use of the instrument, or if any unusual smells or smoke should appear to be caused by
it, immediately turn off the power switch, disconnect the adaptor plug from the outlet, and have
the instrument inspected by qualified Yamaha service personnel.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the
instrument or other property. These precautions include, but are not limited to, the following:

• Do not place the AC adaptor cord near heat sources such as heaters or radiators, and do not
excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a posi­tion where anyone could walk on, trip over, or roll anything over it.

• When removing the electric plug from the instrument or an outlet, always hold the plug itself and
not the cord.

• Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can
result in lower sound quality, or possibly cause overheating in the outlet.

• Unplug the AC power adaptor when not using the instrument, or during electrical storms.

• Always make sure all batteries are inserted in conformity with the +/- polarity markings. Failure
to do so might result in overheating, fire, or battery fluid leakage.

• Always replace all batteries at the same time. Do not use new batteries together with old ones.
Also, do not mix battery types, such as alkaline batteries with manganese batteries, or batteries
from different makers, or different types of batteries from the same maker, since this can cause
overheating, fire, or battery fluid leakage.

• Do not dispose of batteries in fire.

• Do not attempt to recharge batteries that are not intended to be charged.

• When the batteries run out, or if the instrument is not to be used for a long time, remove the
batteries from the instrument to prevent possible leakage of the battery fluid.

• Keep batteries away from children.

• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid should come in
contact with your eyes, mouth, or skin, wash immediately with water and consult a doctor. Bat­tery fluid is corrosive and may possibly cause loss of sight or chemical burns.

• Before connecting the instrument to other electronic components, turn off the power for all com­ponents. Before turning the power on or off for all components, set all volume levels to mini­mum. Also, be sure to set the volumes of all components at their minimum levels and gradually
raise the volume controls while playing the instrument to set the desired listening level.

• Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in
direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel
disfiguration or damage to the internal components.

• Do not use the instrument near other electrical products such as televisions, radios, or speakers,
since this might cause interference which can affect proper operation of the other products.

• Do not place the instrument in an unstable position where it might accidentally fall over.

• Before moving the instrument, remove all connected adaptor and other cables.

• Use the specified adaptor (PA-3B, PA-3C or an equivalent recommended by Yamaha) only.
Using the wrong adaptor can result in damage to the instrument or overheating.

• Before cleaning the instrument, always remove the electric plug from the outlet. Never insert or
remove an electric plug with wet hands.

• Check the electric plug periodically and remove any dirt or dust which may have accumulated on
it.

• Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.

• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning
fluids, or chemical-impregnated wiping cloths. Also, do not place vinyl, plastic or rubber objects
on the instrument, since this might discolor the panel or keyboard.

• Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive
force on the buttons, switches or connectors.

• Do not operate the instrument for a long period of time at a high or uncomfortable volume level,
since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the
ears, consult a physician.

Yamaha cannot be held responsible for damage caused by improper use or modifications
to the instrument, or data that is lost or destroyed.

Always turn the power off when the instrument is not in use.

Make sure to discard used batteries according to local regulations.

The illustrations as shown in this owner’s manual are for instructional purposes only, and
may be different from the ones on your instrument.

Any mention or reference to the DD-20 in this manual also applies to the model DD-20S.

Percussion Pads

Striking two percussion pads
at the same time produces
simultaneous sounds accord­ing to the voices assigned to
the respective pads.

Sensitivity

The DD-20’s main percus­sion pads feature touch
sensors so that they respond
just like acoustic percussion
instruments. Striking the
percussion pads with differ­ent force results in relatively
loud or soft sounds accord­ingly. Be careful not to strike
the pads with excessive force
as this may seriously damage
the percussion pad sensors.

Setting Up

Supplying Power

The DD-20 will operate on either an optional power adaptor or
optional batteries.

▼ To connect a power adaptor:

1. Connect only the Yamaha PA-3B or PA­3C power adaptor to the DC IN jack of
the DD-20.

2. Plug the power
adaptor into an AC
power outlet.

WARNING

Use ONLY the Yamaha PA-3B, PA-3C AC Power Adaptor
(or other adaptor specifically recommended by Yamaha)
to power your instrument from the AC mains. The use of
other adaptors may result in irreparable damage to both
the adaptor and the DD-20.

CAUTION

HEADPHONES/AUX. OUT
jack. The DD-20’s internal
speakers will switch off
automatically when you plug
in a pair of headphones.

▼ To insert batteries:

1. Remove the battery compartment
cover located on the bottom of the
DD-20.

2. Insert six (6) 1.5 V “AA” (R-6, SUM-3) or equivalent
batteries into the battery compartment.

compartment.

3. Replace the battery compartment cover securely.

CAUTION

Never mix old and new batteries or different types of
batteries (e.g., alkaline and manganese).

To prevent possible damage from battery leakage,
remove the batteries from the instrument if it is not to
be used for a long time.

❏

When the batteries are low, replace with a complete set of six new
batteries. Never mix old and new batteries or different types of batter­ies. The batteries are low when the DD-20’s voices become noticeably

Troubleshooting

Specifications

In many cases, seemingly big problems or
malfunctions can be remedied easily. Please
check the following list before deciding that
your DD-20 is broken.
If the problem is not listed here or the suggested
remedy is ineffective, take the DD-20 to an
authorized Yamaha dealer for proper diagnosis
and repairs. Do not attempt to repair this digital
percussion instrument as serious damage may
occur.

❏ This is a normal power surge noise that occurs

when the STANDBY/ON switch is operated.

The LED display is completely dark.

❏ The batteries are low and should be replaced

immediately.

No sound comes from the speakers.

❏ The volume is turned down too low and should be

adjusted up appropriately.

❏ A plug is inserted into the HEADPHONES/AUX.

OUT jack and should be taken out immediately.

The wrong voice plays when you strike a percus­sion pad.

❏ The desired voice has not been assigned to the

percussion pad. Use the PAD ASSIGN function to
program the desired voice to the appropriate
percussion pad.

The custom pad voice assignments have disap­peared or defaulted.

immediately.

display goes dark momentarily and then changes
to the default reading “00”.
