Rear Panel (Connecting Your Equipment)
* To prevent malfunction and equipment failure, always turn down the
volume, and turn o all the units before making any connections.
A B C D
A INPUT (A/MONO, B) jacks
Connect your guitar, bass, or eect unit here.
Use the A/MONO and B jacks if connecting an eect
unit that has stereo output. Use only the A/MONO jack
if using this unit in mono.
Turning On/O the Power
The INPUT A/MONO jack also operates as the power
switch. The power turns on when you insert a plug into
the INPUT A/MONO jack.
When powering up
Power-up equipment such as your guitar amp last.
When powering down
Power-down equipment such as 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.
B OUTPUT (A/MONO, B) jacks
Connect this jack to your amp or monitor speakers.
Use only the OUTPUT A/MONO jack if using this unit in
mono. Even sound that is input in stereo is output in
mono.
The input/output jacks can be used to utilize the insert
loop function (p. 13).
C CTL 1, 2/EXP jack
Using the jack as CTL 1, 2
You can connect a footswitch (sold separately: FS-5U,
FS-6, FS-7) and use it to tap-input the rate or switch
memories (p. 11).

Panel Descriptions

Using the jack as EXP
You can connect an expression pedal (sold separately:
EV-30, Roland EV-5, etc.) and use it to control the rate or
the volume of the eect sound (p. 13).
* Use only the specied expression pedal. By connecting any other
expression pedals, you risk causing malfunction and/or damage
to the unit.
D DC IN jack
An AC adaptor (sold separately: PSA-S series) can be
connected to this jack.
* Use only the specied AC adaptor (sold separately: PSA-S series)
and plug it into an AC outlet of the correct voltage.
* If the AC adaptor is connected while power is on, the power
supply is drawn from the AC adaptor.
Side Panel (Connecting Your Equipment)
E F
E MIDI jacks
Use a TRS/MIDI connecting cable (sold separately:
BMIDI-5-35) to connect an external MIDI device. You can
use an external MIDI device to switch the memories of
this unit.
* Do not connect an audio device here. Doing so will cause
malfunctions.
F USB port (for program updates only)
Connect your computer using a commercially available
USB cable that supports USB 2.0.
* Do not use a micro USB cable that is designed only for charging a
device. Charge-only cables cannot transmit data.
* This is used only for program updates.

Saving to Memory
Here’s how to save eect settings that you edited.
1. Long-press the [MEMORY] button.
The display indicates “Wrt.”
2. Press the [MEMORY] button to select the save-
destination (MAN, 1–4).
If you decide to cancel, press the [TAP DIVISION]
button.
3. Long-press the [MEMORY] button to conrm
the save-destination.
The memory is saved.
* If you save to MAN, the settings of the panel are applied as the
values for MODE, DEPTH, E.LEVEL, and PARAM 1–3.
Switching Memories
Here’s how to recall a saved memory.
1. Press the [MEMORY] button to select a
memory.
Each time you press the button, you cycle through
the memories in the order of “MAN (manual) 01
02 03 04 0MAN...”
What is “MAN” (manual)?
This unit normally applies the eect according to the
settings that are saved in memory, but if you select MAN
(manual) the eect is applied according to the positions
of the panel knobs. Even in this case, the rate and TAP
DIVISION recall the settings that are written to MAN (this
can be changed).

Installing Batteries
Insert the batteries as shown below, being careful to
orient the batteries correctly.
* Batteries should always be installed or
replaced before connecting any other
devices. This way, you can prevent
malfunction and damage.
* If operating this unit on batteries, please
use alkaline batteries.
* Even if batteries are installed, the unit
will turn o if you connect or disconnect
the power cord from the AC outlet while
the unit is turned on, or if you connect or
disconnect the AC adaptor from the unit.
When this occurs, unsaved data may be
lost. You must turn o the power before
you connect or disconnect the power
cord or AC adaptor.
* When turning the unit over, be careful
so as to protect the buttons and knobs from damage. Also, handle the
unit carefully; do not drop it.
* 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”(leaet “USING THE UNIT SAFELY” ).
* “Lo” will appear on the display if the batteries are low. Replace them
with new ones.
