7 In 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).

7 New RISE/FALL features give you continuous rising and falling

eects unavailable with previous phasers.

7 You 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.

7 Includes 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.

Panel DescriptionsMain Features

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.
