7In addition to the standard four setting types available on
previous phasers (4-/8-/10-/12-stage), the PH-3 adds further
features, including new RISE and FALL eects and a STEP
setting which changes the eect in steps, for a total of seven
switchable phase eects (an eect that adds a cyclic sensation
to the sound).
7New RISE/FALL features give you continuous rising and falling
eects unavailable with previous phasers.
7You can use the PH-3’s pedal to set the RATE to the tempo. This
makes it easy to sync to songs (tempo and measure), formerly
a dicult process.
7Includes an expression/control jack. You can connect an
expression pedal (Roland EV-5, BOSS EV-30; sold separately)
to this jack and make continuous changes to the RATE for
a rotary speaker-like sound, while connecting a foot switch
(BOSS FS-5U; sold separately) allows you to match the rate to
the tempo.
This device will enter Sleep mode (power conservation mode)
when ten hours have elapsed since the last operation, or since
the last audio input while in Stop mode.
If you want to prevent the device from entering Sleep mode,
carry out the procedure described on p. 12.

1. DC IN jack
Accepts connection of an AC Adaptor (PSA series; sold
separately). By using an AC Adaptor, you can play without being
concerned about how much battery power you have left.
* As soon as you connect the AC adaptor, the unit is turned on.
* We recommend that you keep batteries installed in the unit
even though you’ll be powering it with the AC adaptor. That
way, you’ll be able to continue a performance even if the cord
of the AC adaptor gets accidentally disconnected from the
unit.
* Use only the specied AC adaptor (PSA-series).
* If the AC adaptor is connected while power is on, the power
supply is drawn from the AC adaptor.
2. CHECK indicator
Combination indicator that shows the eect’s on/o status,
tempo (in Tempo mode: p. 9), and Battery Check function.
The indicator is lit when the eect is on, thereby allowing you to
check whether the eect is on or o.
The indicator lights when an eect is ON.
* If the indicator dims when the eect is on or when the tempo
is being displayed, it means that the battery is running out
of reserve; when this occurs, replace with fresh batteries. For
instructions on changing the batteries, refer to“Changing the
Battery” (p. 11).
* The CHECK indicator shows whether the eect is being
applied or not, and is used to indicate other eects. It does not
indicate whether the power to the device is on or not.
3. OUTPUT jack
Connect an amplier to this jack.
4. INPUT jack
This jack accepts input signals (coming from a guitar, some
other musical instrument, or another eects 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 o. When you are not using the unit,
pull the plug out of the INPUT jack.
5. EXP/CTL jack
Accepts connection of an expression pedal (Roland EV-5; sold
separately) or momentary- type foot switch (BOSS FS-5U; sold
separately). Use the EV-5 to change the RATE continuously.
Setting tempos is easy with the FS-5U.
* For details, refer to“Using the EXP/CTL Jack” (p. 10).

6. Pedal Switch
Used for switching eects on/o, and for inputting the tempo.
When the eect is on, be sure to start any changes with the lter
at the lowest setting.
* For inputting the tempo, refer to “Setting the Tempo with the
PH-3’s Pedal Switch”(p. 9).
7. Thumbscrew
When this screw is loosened, the pedal will open, allowing you
to change the battery.
* For instructions on changing the battery, refer to“Changing
the Battery” (p. 11).

8. RATE knob
Adjusts the speed at which the lter changes.
When set to MIN, the lter remains o.
9. DEPTH knob
Adjusts the depth of the lter change.
The lter eect stops when this is set to MIN with the STAGE
switch set to anything besides FALL or RISE.

10. RES (Resonance) knob
Adjusts the strength of the lter eect. The eect sound
becomes stronger the further the knob is turned clockwise.
* Raising the RES setting (turning it clockwise) makes it easier
for the sound to become distorted. If it appears that the sound
is becoming distorted, try lowering the RES setting.
11. STAGE switch
Selects the number of phase steps and the phase type. The
higher the number, the more depth the phaser eect has.
Type Explanation
44-stage phaser; a light, vintage phaser eect with
a classic feel.
88-stage phaser that gives a balanced phaser
sound.
10 10-stage phaser providing a deep phaser eect.
12 12-stage phaser, with two sixstage phasers
connected in series for a powerful phaser eect.
FALL Phase eect featuring a continuously falling
sensation.
RISE Phase eect that imparts a continuously rising
sensation.
Type Explanation
STEP
Phase eect whereby lter modications occur in
a non-consecutive manner. This can provide some
really unique, illusional eects.

* Inserting a plug into the INPUT Jack will automatically switch the unit on.
* To prevent malfunction and equipment failure, always turn down the volume, and turn o all the units before making any
connections.
* Use only the specied expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to
the unit.
* Once you’ve gotten hooked up correctly, be sure to observe the following order when switching on the power to your equipment. By
turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
When powering up: Turn on the power to your guitar amp last.
When powering down: Turn o the power to your guitar amp rst.
* Before turning the unit on/o, always be sure to turn the volume down. Even with the volume turned down, you might hear some
sound when switching the unit on/o. However, this is normal and does not indicate a malfunction.
* When operating on battery power only, the unit’s indicator will become dim when battery power gets too low. Replace the battery as
soon as possible.
* If you handle batteries improperly, you risk explosion and uid leakage. Make sure that you carefully observe all of the items related
to batteries that are listed in“USING THE UNIT SAFELY” and “IMPORTANT NOTES”(supplied on a separate sheet).
* The use of an AC adaptor is recommended as the unit’s power consumption is relatively high.
* A battery was installed in the unit before it left the factory. The life of this battery may be limited, however, since its primary purpose
was to enable testing. If operating this unit on batteries, please use alkaline batteries.

Operating the Unit
2, 5 2, 6 32, 4
1. When you have nished making the connections
(p. 6), press the pedal switch to turn the eect on.
(the CHECK indicator is lit).
2. Set the RATE, DEPTH, and RES knobs at the center
position.
3. Use the STAGE switch to select the stage type.
4. With the RATE knob, adjust the speed of the lter
change.
* When set to MIN, the lter remains o.
5. With the DEPTH knob, adjust the depth of the lter
change.
* The lter eect stops when this is set to MIN with the STAGE
switch set to anything besides FALL or RISE.
6. With the RES (Resonance) Knob, adjust the strength
of the lter eect.
* Raising the RES setting (turning it clockwise) makes it easier
for the sound to become distorted. If it appears that the sound
is becoming distorted, try lowering the RES setting.

9
Setting the Tempo with the PH-3’s Pedal Switch
* RATE cycles for use with the tempo settings can be made in
the range of 0.2–16 seconds.
1. Step on, and continue depressing the PH-3’s pedal
switch for at least two seconds.
If the pedal switch is pressed when the eect is on, the CHECK
indicator goes out, and the eect is turned o for two seconds.
If the pedal switch is pressed when the eect is o, the CHECK
indicator turns red, and the eect is turned on for two seconds.
* For switching without the normal stress and hassle of turning
eects on and o, when you go into the tempo setting mode
while the eect is on, the eect is rst switched o for two
seconds, and the PH-3 switches to tempo setting mode.
2. The CHECK indicator then ashes in red and green,
and the tempo can then be set with the eect on.
* Here, the tempo is indicated by the value set with the RATE
knob.
3. Press the PH-3’s pedal switch in timing with the
tempo.
The CHECK indicator then ashes in red and green in time with
the tempo.
* When the pedal switch is pressed, the lter is completely
lowered (except when set to RISE or FALL). When using this,
even if the RATE (as shown by the ashing CHECK indicator)
is o slightly from the tempo, you can match the RATE to the
tempo with one step on the PH-3’s pedal.
MEMO
Setting the RATE near the desired tempo beforehand allows
you to make faster and more natural tempo settings.
4. Press and continue holding the PH-3’s pedal switch
for two seconds or longer to nish setting the tempo.
The eect goes on, and instead of ashing in red and green, the
CHECK indicator will light steadily in red.
* When you have nished setting the tempo, the RATE changes
to the value for the tempo setting made with the pedal, so the
value will dier from the value indicated by the RATE knob.
* When changed with the RATE knob, the tempo is then the
same as the value for the RATE knob.
English

10
Using the EXP/CTL Jack
* When an EV-5 or FS-5U is connected to the EXP/CTL jack, the
PH-3’s own pedal switch then only turns the eect on and o.
* When disconnecting from the EXP/CTL jack, the RATE (tempo)
settings used up to that point are cleared, with the RATE knob
setting then becoming eective.
When Connecting the (Optional) Roland EV-5
The RATE settings can be adjusted with the EV-5.
You can change from the minimum RATE value set by the EV-5’s
Minimum Value to the value set with the PH-3’s RATE knob.
1. Connect the EV-5 to the EXP/CTL jack, and
press the pedal completely forward. The
adjustment made with the RATE knob in this
condition determines the maximum RATE
value when controlled with the EV-5.
2. Return (raise) the pedal completely back so
the heel is down. The adjustment made with
the RATE knob at this point determines the
minimum RATE value when controlled with
the EV-5.
When Connecting the (Optional) BOSS FS-5U
The tempo can be set with the FS-5U.
Concerning how to make the tempo settings, refer to steps 3
and 4 under ”Setting the Tempo with the PH-3’s Pedal Switch”
(p. 9). Simply substitute“FS-5U” where it says “PH-3’s pedal
switch.”
* The PH-3’s pedal switch switches the eect on and o. When
the eect is on, the CHECK indicator ashes alternately in red
and green.
* If you turn the RATE after setting the tempo with the FS-5U,
the RATE knob value is then adjusted.
* You can also make the tempo settings with the eect o.
* Set the polarity switch of the connected the FS-5U as shown
in the gure below.

Changing the Battery
When the CHECK indicator goes dim or no longer lights while an
eect is on, it means that the battery is nearly dead and must be
replaced. Replace the battery following the steps below.
* The use of an AC adaptor is recommended as the unit’s power
consumption is relatively high.
* A battery was installed in the unit before it left the factory. The life
