e
Please
read
these
instructions
carefully
for
proper
operating
procedures
for
the
BOSS
DD-3.

CAUTIONS
* When you do not use the unit for a long
period, remove the battery to prevent
current leakage and leaking of sticky
substance,
e When battery voltage drops, effect
becomes inferior or no sound is pro-
duced. To prevent that, replace the
battery alittle earlier,
AC ADAPTOR (OPTION)
* Be sure to keep the battery snapped by
connector into the housing, when using
AC adaptor, too.
*Even if AC Adaptor cord comes out
during performance, operations imme-
diately changes to battery, causing no
trouble in continuing performance.
* Power is switched on while a plug is put
into input jack. When you do not use,
keep the plug off the jack.
* For AC operation, be sure to use the
BOSS AC Adaptor PSA-120, 220 or
240 depending on the voltage system
in your country, and never use one
Adaptor for two units simultaneously.

FEATURES
e
The
DD3
is
the
first
compact
digital
delay.
The
DD-3
allows
wider
range
ot
delay
time
(12.5ms
to
800ms)
and
frequency
response
(40Hz
to
7kHz/
at

than
conventional
analog
sys-
tem
one.
*
The
Pedal
Switch
has
double
duty
of
Effect
ON/OFF
and
Hold
ON/OFF.
Hold
Effect
is
made
attainable
by
its
digital
system.

to
use
the
AC

depending
on
the
voltage

tem
in
your
country.

not
be
used,
as
the

units.
*
The
battery
(one

will
last
for
30
minutes
to
2
hours

depending
on
the
conditions.
The
use
of
a

sound
is
equivalent
to
that
of

input
signal
can
cause
beat
notes,
making
Delay

muddy.
Slight
counterclockwise
rotation
of
D.
TIME
will
decrease
beats.
Adjust the repetition time by setting
the Feedback knob to a proper posi-
tion.
*1f this knob is set too high, oscilla-
tion may occur.
Adjust the output level of delay sound.
*Turning the knob to MAX makes the
level of delay sound equivalent to
the direct sound.
*When this knob is set to MIN in
stereo rnode, the delay sound is not
output through the Main Output.
(2) HOLD EFFECT
After connecting all the
cords required, set the all
knobs on the panel as illus-
J| trated.

Switch down, Hold is OFF (Normal).
*When you press the Pedal Switch down
after playing some phrases, the last
sound played will take on the Hold
effect.
*The Pedal Switch works as long as the
pedal is held down.
The delay time knob adjust the Hold
Time (200ms to 800ms). When you
rotate this knob while the hold sound is
heard, its pitch changes; rotating it
clockwise towers the pitch and counter-
clockwise raises it.

which
can
be
determined
by
turning
the
equipment
on

the
user
is
encouraged
to
try
to
correct
the
interference
by
the
following
measure:
e
Disconnect
other
devices
and
their
input/output
cables
one
at
a
time.
If
the
interference
stops,
it
is
caused
by
either
the
other
device
or
its
I/O
cable.
These
devices
usually
require
Roland

you
can
Obtain

using
one
or
more
of
the
following
measures:
*
Turn
