Features

The compact Boss PS-5 pitch shifter is
equipped with a high-performance 24­bit DSP (digital sound processor) chip,
and features numerous functions with
high-quality sound.

Select from five modes to use - PITCH
SHIFTER, HARMONIST, DETUNE,
T.ARM, and FLUTTER (new effect).

You can get split functions on this one
device, with the Pitch Shifter going into
effect when chords are played, and
Harmonist when playing single notes.

You can even use the Harmonist post­distortion effects devices.

Delay control and stereo outs provide
even more effective detuning.

Effects simulating guitar arming
(T.Arm and Flutter) are included.

With an expression pedal (Roland EV­5; sold separately) connected, you can
get continuous control of the amount
of pitch shift while you play.

*1 In HARMONIST mode, the instrument’s

scale is detected and harmonies are added
to the output. Make sure the instrument is
tuned correctly in this mode. Errors in
tuning will cause the harmonies to be out
of tune as well. In addition, tune the
instrument by setting the reference pitch
A4 to 440 Hz.
Monitor post-distortion volume levels
with the PS-5 after a distortion effects
device in the signal path. Excessive
volume levels can cause the harmony
tuning to slip.

IMPORTANT NOTES

In addition to the items listed under “US­ING THE UNIT SAFELY” on page 37,
please read and observe the following:

Power Supply: Use of Batteries

•Do not use this unit on the same power cir­cuit with any device that will generate line
noise (such as an electric motor or variable
lighting system).

•The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.

•The use of an AC adaptor is recommended
as the unit’s power consumption is relative­ly high. Should you prefer to use batteries,
please use the alkaline type.

•

Batteries should always be installed or re­placed before connecting any other devices.
This way, you can prevent malfunction and/

4

or damage to speakers or other devices.

•A battery is supplied with the unit. The life
of this battery may be limited, however,
since its primary purpose was to enable
testing.

•Before connecting this unit to other devices,
turn off the power to all units. This will help
prevent malfunctions and/or damage to
speakers or other devices.

Placement

•Using the unit near power amplifiers (or
other equipment containing large power
transformers) may induce hum. To alleviate
the problem, change the orientation of this
unit; or move it farther away from the
source of interference.

•This device may interfere with radio and
television reception. Do not use this device
in the vicinity of such receivers.

•Do not expose the unit to direct sunlight,
place it near devices that radiate heat, leave
it inside an enclosed vehicle, or otherwise
subject it to temperature extremes. Exces­sive heat can deform or discolor the unit.

•To avoid possible breakdown, do not use
the unit in a wet area, such as an area ex­posed to rain or other moisture.

Maintenance

•For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be
sure to wipe the unit thoroughly with a soft,
dry cloth.

•Never use benzine, thinners, alcohol or sol­vents of any kind, to avoid the possibility of
discoloration and/or deformation.

Additional Precautions

•Use a reasonable amount of care when using
the unit’s buttons, sliders, or other controls;
and when using its jacks and connectors.
Rough handling can lead to malfunctions.

•When connecting / disconnecting all cables,
grasp the connector itself-never pull on the
cable. This way you will avoid causing shorts,
or damage to the cable’s internal elements.

•To avoid disturbing your neighbors, try to
keep the unit’s volume at reasonable levels.
You may prefer to use headphones, so you do
not need to be concerned about those around
you (especially when it is late at night).

•When you need to transport the unit, pack­age it in the box (including padding) that it
came in, if possible. Otherwise, you will
need to use equivalent packaging materials.

•Use only the specified expression pedal
(EV-5; sold separately). By connecting any
other expression pedals, you risk causing
malfunction and/or damage to the unit.

1. AC adaptor jack

An AC adaptor (BOSS PSA-series: sold
separately) can be connected to this jack.
If an AC adaptor is used, you will be able
to play for extended periods without
worrying about battery life.

* As soon as you connect the AC adaptor,

the unit is turned on.

* If there is the battery in the unit while an

AC adaptor is being used, normal
operation will continue should the line
voltage be interrupted (power blackout or
power cord disconnection).

2. CHECK indicator

This indicator shows whether an effect is
on/off, and also doubles as the Battery
Check indicator.
The indicator lights when an effect is on.
If this indicator goes dim or no longer
lights while an effect is on, the battery is
near exhaustion and should be replaced
immediately. For the procedure, refer to
“Changing the battery” (page 28).

3. OUTPUT jacks A(MONO)/B

These output jacks are connected to an
amplifier or other effects device. The
sound is output at the volume set with the
BALANCE knob.

* The output varies with the MODE switch

setting. For more detailed information,
refer to “Description of Each Mode” (p.
14–25).

4. INPUT jack

This jack accepts input signals (coming
from a guitar, some other musical instru­ment, or another effects unit).

* When a battery is used, the INPUT jack

also functions as a power switch. When a
plug is inserted into the INPUT jack, the
power will be turned on. When the plug is
pulled out, the power will be turned off.
When you are not using the unit, pull the
plug out of the INPUT jack.

5. EXP jack

Connect an expression pedal (Roland EV­5; sold separately) here. Depressing the
pedal changes the amount of pitch shift.
For more detailed information, refer to
“Description of Each Mode” (page 14–25).

6. Pedal switch

Pressing this switch will turn the effect
on/off.

7. Thumbscrew

When this screw is loosened, the pedal
will open, allowing you to change the bat­tery. For the procedure, refer to “Chang­ing the battery” (page 28).

8. D.TIME/SPEED knob

* This is not effective in PITCH SHIFTER/

HARMONIST mode.

In T.ARM / FLUTTER modes:

This adjusts the speed of the pitch
change. The more the button is rotated
to the right, the faster the shift rate.

In DETUNE mode:

This adjusts the delay time. The delay
time is increased as the knob is rotated
to the right.

9. BALANCE knob

This adjusts the output balance between
the direct sound and the effect sound.

In PITCH SHIFTER / HARMONIST /
DETUNE modes:

With the BALANCE knob set at the
center position, the direct sound and ef­fects sound are output equally (1:1).

When the knob is rotated completely to
the left, only direct sound is output;
when the knob is turned all the way to
the right, only the effect sound is output.

In T.ARM / FLUTTER modes:

This adjusts the volume of the output
sound.
No effect sound is output when the
knob is turned completely to the left;
with the knob all the way to the right,
the sound is boosted by 6 dB.

10. H.R KEY switch

This selects the key for performing in
HARMONIST mode.
This determines the harmonic scales used
for each scale input from the song’s key
and intervals (position of the PITCH
switch setting). For more detailed infor­mation, refer to “Key setting” (page 18).

9

* The proper harmony intervals will not be

output if the song is played in the wrong key.

11. PITCH switch

In PITCH SHIFTER / DETUNE / T.ARM
/ FLUTTER modes:

This sets the degree of pitch shift. For
more details, refer to “Description of
Each Mode” (page 14–25).

In HARMONIST mode:

This sets the interval. For more details,
refer to “Description of Each Mode”
(page 16–19). For more on the harmon­ic scales output based on the H.R KEY
switch and the PITCH switch (interval)
settings, refer to “About the scale of the
effect sound” (page 19).

12. MODE switch

This is used for selecting the PITCH
SHIFTER, HARMONIST, DETUNE,
T.ARM, and FLUTTER modes. For more
on the functions for the knobs in each
mode, refer to “Description of Each
Mode” (page 14–25).

causing malfunction and/or damage to the unit.

* When using the PS-5 for monaural sound, connect the OUTPUT A

jack to your guitar amplifier.

* Inserting a plug into the Input Jack will automatically switch the unit on.
