Supplying Power

The DD-9 will operate on either an optional power adaptor or
optional batteries.

▼

To connect a power adaptor:

1. Connect only a Yamaha PA-1, PA-1B or

PA-3 power adaptor to the DC IN jack of
the DD-9.

2. Plug the power adaptor into an

AC power
outlet.

Caution: The use of any other power adaptors may
cause serious damage to the DD-9.

▼

To insert batteries:

1. Remove the battery compartment cover located on the bottom

of the DD-9.

2. Insert six (6) 1.5 V “AA” (R-6, SUM-3) or equivalent batter-

ies into the battery compartment.

Make sure the polarities are lined up as indicated in the battery
compartment.

3. Replace the battery compartment cover securely.

Caution: To prevent damage due to battery leakage,
remove all the batteries from the instrument when it is
not to be used for an extended period of 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-9’s voices become noticeably distorted or the DD-9
resets to default settings unexpectedly

Setting Up

Headphones

You can use a standard pair of
stereo headphones, such as
Yamaha’s HPE-3 or HPE-150,
with the DD-9 for private
practice.
To connect headphones insert
the headphone plug into the
HEADPHONES/AUX. OUT
jack.  The DD-9’s internal
speakers will switch off
automatically when you plug
in a pair of headphones.

Percussion
Pads

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

Sensitivity

The DD-9’s main percussion
pads feature touch sensors so
that they respond just like
acoustic percussion instru-
ments. Striking the percus-
sion 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.
