| INSTRUCTIONS
Please read the instructions carefully.

The RPS-10 features two functions; Pitch Shifter and
Digital Delay.
e When used as a pitch shifter, the RPS-10 allows
pitch shifting freely from —1 to +1 octave.
è Setting up a keyboard, desired pitch shifting can be
selected at once.
e The newly developed LSI enables to reduce the
possible tremolo and time lug.
e When used as a delay machine, the RPS-10 allows
to set the delay time from 25 to 800ms.
e The direct sound has frequency response from
20Hz to 30kHz and the effect sound from 40Hz to
15kHz.
r
e in both Pitch Shifter and Delay modes, the INV
(invert) position serves to create tape recorder’s
reverse playback like effect.

RADIO AND TELEVISION INTERFERENCE
“Warning - This equipment has been verified to comply with the limits for a Class 8 compuüng device
pursuant to Subpart J, of Part 15, of FCC rules. Operation with non-certified of non-vertied equip
ment is bkely ta result in interference to radio and TY reception.”
The equipment described in this manual generates and uses radio-frequency energy. ff it is not
installed and used property. that is, in strict accordance with our instructions, it may cause interfer.
ence with radio and television reception
Tris equipment has been tested and found to comply with the limits for a Ciass B computing
device in accorgance with the specifications in Subpart J, of Part 15. of FCC Rules. These ruies are
designed to provide reasonable protection against such a interference in a residential instailauon
However, there is no guarantee that the interference will not occur in a particular installation. if this
equipment goes cause interference to radio or television reception, which can be determinea by turning
the equipment on and off, the user ts encouraged to try to correct the interference by the
following measure:
s 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 LO cable.
These devices usually require Roland designated shielded 10 cabies. For Roiand cevices. you can
obtain the proper shielded cable from your dealer. For non Roland devices, contact the manufacturer
or dealer tor assistance.
if your equipment does cause interference to radio or television reception, you can try to correct
the interference by using one or more of the following measures:
e Turn the TV or radio antenna until the interferences stops.
è Move the equipment to one side or the other of the TV or radio
e Move the equipment farther away from the TV or radio.
ə Plug the equipment into ‘an outlet that is on a different 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.
e consider installing a rooftop television antenna with coaxial cabie lead-in between the antenna and

if necessary, you should consult your dealer or an experienced radio television technician for
additional suggestions. You may find helpful the following booklet prepared by the ‘Federal Com.

@ INPUT JACKS
The standard phone jack and the pin jack cannot be
used at a time. If both are connected, the standard
phone jack will work.
@ LEVEL SWITCH
Set this switch depending on the output level of the
connected device. If the sound is distorted at the
"“-20dBm” position, change the switch to the
“—~10dBm” position.
@ OUTPUT JACKS
Both the standard phone and pin jacks can be simul-
taneously used. `
®© HOLD JACK
By connecting the footswitch FS-1 (optional) to the
Hold Jack, the effect sound can be sustained with the
pedal operation.
* Please do not switch on or off the unit while the
Hold effect is on.
@ EFFECT REMOTE JACK
By connecting the footswitch FS-1 (optional), the
Normal or the Effect mode can be selected with the
pedal operation.
* Please make sure that the Effect Switch is turned on.

[2] PITCH SHIFTER
The amount of the pitch shifting can be set within a
range of —1 to +1 octave.
The amount of the pitch shifting can be controlled
either with the knobs on the RPS-10 or externally by
the keyboard.
By connecting a chromatic tuner such as TU-12,
TU-12H, TU-100, the amount of the pitch shifting set
on the RPS-10 can be seen in the Display and the
Meter of the tuner.
When all the necessary connections are made, turn
the RPS-10 on.
* Turn the amplifier on in the end.

In this mode, the delay time of the effect
sound is short. Low frequency sound may
not be properly pitch shifted, therefore
may take on tremolo.
In this mode, delay time is longer than the
Mode A. Even a low frequency sound can
be accurately pitch shifted.
The tremolo is considerably reduced,
creating stable effect sounds.
In this mode, a unique sound can be ob-
tained by mixture of the tape recorder’s
reverse playback like effect and the pitch
shifting effect.

SA
While the keyboard is connected to the Keyboard
Control Jack, the Pitch Knob @ and the Pitch Fine
Knob @ do not:work.
The ideal keyboard sound is that with a simple
waveform (“\,, AN or [U ), a short attack time and
a long release time.
* Make sure that the range of the sound from the
keyboard is wider than C5 (523.25Hz) to C7
(2093Hz).
* When using a polyphonic synthesizer, do not play
more than one key at a time.
Do not use a complicated signal such as a chord,
a sound with chorus effect, etc. Such sounds will
not be accurately pitch shifted.
An electric guitar cannot be used for controlling the
pitch shifting.
* The amount of the pitch shifting for each keyboard
is zero cent at C6 (1046.5Hz, two octaves higher
than Middle C), and changes in semi-tone steps up
to +1 octave (See the right picture).

[5] IMPORTANT NOTES
For about 10 seconds after powered up, this unit
does not function because of the muting circuits.
Be sure to use the AC Adaptor BOSS PSA-120, 220
or 240 depending on the line voltage system in
your country.
When you use only an AC adaptor for supplying
power to more than one unit, please be sure that
the total current draw does not exceed 200mA.
(The current draw of each unit is shown on its rear
panel.)
When the unit is not to be used for a long period of
time, disconnect the AC adaptor from the wall
socket.
Avoid using the unit in extreme heat or humidity or
where it may be affected by dust.
When you use only Micro Studio Series without
optional Rack Mount Adaptor “RAD-10", please
attach the rubber feet. Refer to figure.
AC ADAPTOR BOSS PSA-120, 220 OR 240
Be sure to use the optional BOSS PSA series. Using
any other adaptor wili cause trouble.
RACK MOUNT INSTALLATION
The RPS-10 is one of the BOSS Micro Studio Series,
and by using the Rack Mount Adaptor RAD-10, any
two sets of the Series can be mounted in a standard
19” rack (EIA-1U). Remove the rubber feet (x4) from
the units, then attach the units to the Rack Mount
Adaptor RAD-10, then mount the whole set in the
rack. i
