FEATURES
The BOSS RDD-10 is a compact yet versatile digital
delay machine. By changing the delay time range(9
steps) and modulation, you can enjoy various types of
effects; not only echo but also flanging or doubling
chorus effect, etc. Also, the Delay Tone Knob allows
you to make a mild echo like an analog delay’s as well
as a sharp echo. Two RDD-10‘s can be set up through
their Modulation Buses for modulation sync. Moreover,
the phase of the modulation can be inverted with the
Polarity Switch, creating wide variety of stereo effects.
Both standard phone and pin jacks are provided for an
Output or input, and more, the Level Switch (-20dBm
/ -—10dBm} is featured, allowing applied setups su-
ch as with audio and video equipment as well as
usual use with musical instruments. The RDD-10 is one
of the BOSS Micro Studio Series, and any two sets of
them
can
be
set
up
on
the
Standard
19”
rack{ElA-1U)
by using the optional rack mount adaptor RAD-10.

Radio and television interference
“Warning
—
This
equipment
has
been
verified
to
comply
with
the
limits
for
a
Class
B
computing
device,
pursuant
to
Subpart
J,
of
Part
15,
of FCC
rules.
Operation
with
non-certified
or
nonverified
equipment
is
likely
to
result
in
interference
to
radio
and
TV reception.”
The equipment described in this manual generates
and uses radio-frequency energy. If it is not installed
and used properly, that is, in strict accordance with
our instructions, it may’ cause interference with
radio and television reception.
This equipmeni has Veen Sted SIG ToOUAG tT COIN
ply with the simits for a Class 8 computing device in
accordance with the specifications in Subpart J, of
Part 15, of FCC Rules. These rules are designed to
provide reasonable protection against such an inter-
ference in a residentiat installation.
However, there is no quarantee that the interference
will not occur in a particular installation, If this
equioment Goes cause interference to radio or televi-
sion reception, which can be determined by turning
the equipment on and off, the user is encouraged to
try to correct the interference by the following
measure:
@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 1/O cable.
These devices usually require Roland designated
shielded I/O cables. For Roland devices, you can
obtain the proper shielded cable from your dealer.
For non Roland devices, contact the manufacturer
or deater for assistance.
lf your equipment does cause interference to radio
or television reception, you can try iv correct ihe
interference by using one or more of the following
measures:
@Turn the TV or radio antenna until the interfer:
ence stops.
' @Move the equioment to one side or the other of
the TV or radio,
@Move the equipment farther away from the TV or
radio,
@Plug the equipment into an outlet that is on a dif-
ferent circuit than the TV or radio, (That is, make
certain the equipment and the radio or television
set are on circuits controlled by different circuit
breakers or fuses.)
@Consider installing a rooftop television antenna
with coaxial cable lead-in between the antennas
and TV.
If necessary, you should consult your dealer or an
expertenced radio/television technician for addi-
tional suggestions, You may find helpful the follow-
ing booklet prepared by the Federal Communica-
tions Commission:
“How to identify and Resolve Radio-TV Interfer-
ence Problems”

@ Set the Level Switch to the appropriate posit-
ion depending on the type of the connected
unit.
* If it is the noise that you wish to avoid more
than anything, set the switch to “—20dBm”.
Changing the position of the Level Switch will-
not affect the volume.
() Set a delay time by using the Delay Time Ran-
ge and the Fine Knobs. 1.5 to 6.Oms is requ-
ired for a flanging effect, 12.5 to 50ms for a
chorus effect and 50 to 400ms for delay(echo)
effect.
@
Adjust
the
rate
of
the
LFO
modulation
with
the
Modulation
Rate
Knob,
and
the
depth
with
the
Depth
Knob.
Usually,
set
the
rate
slow
and
the
depth
deep
for
a
flanging
effect,
and
set
both
knobs
to
the
center
positions
for
chorus.
For
a
delay{echo)
effect,
set
the
Dep-
th
Knob
to
“MIN".
() Adjust the Feedback Level with the Feedback
Level Knob. At the “MIN” position, single delay
is obtained. When the delay time is long ( =ec-
ho effect), the Feedback Level Knob serves to
set how many times the delay sound is to be
repeated.
When
it
is
set
short(=flanging
effe-
ct),
the
same
knob
serves
to
adjust
the
reson-
ance.
* As you rotate the Feedback Level Knob clo-
ckwise, the unit may start oscillating.

MNOTES
® Be sure to use the BOSS AC Adaptor PSA-120,
220 or 240 depending on the line voltage sy-
stem in your country.
@VWhen you are using only one AC adaptor for
supplying power to more than one unit, please
be sure that the total current draw does not
exceed 200mA. Please note that two AC ada-
ptors are needed for supplying power to two
sets of the RDD-10's
@ Avoid operating this unit in excessive heat or
humidity or where tt may be affected by dust.
@ Please never remove the cabinet from the unit.
@When you use only Micro Studio Series with-
out optional Rack Mount Adaptor “RAD-10”,
please attatch the rubber feet. Refer to figure.

MRACK MOUNTING
The RDD-10 is one of the BOSS Micro Studio
Series, and any two of them can be mounted in
a standard 19” rack {EIA-1U) by using the opti-
onal Rack Mount Adaptor RAD-10.
Remove the rubber feet from the bottom of the
units, fix the units on the Rack Mount Ada-
ptor with the supplied screws, then place the
whole set on the rack.
