1 Display
Shows the delay time, etc.
2 [TIME] knob
Species the delay time.
Each time you press the button, the delay time
indication switches between time and tempo (BPM).
Example indications
1 ms = “1”, 100 ms = “100”, 1 s = “1.00”,
Tempo: 120 = “120.”, Tempo: 1000 = “1K.”,
Tempo: 99000 = “99K.”, Tempo: 100000 = “10.K.”
3 [FEEDBACK] knob
Adjusts the amount of feedback (amount of repetition).
* Depending on the sound that’s being input and on the position of
the knob, oscillation might occur.
4 [E.LEVEL] knob
Adjusts the volume of the eect sound.
If the mode is REVERSE, maximizing E.LEVEL cuts the
direct sound.

5 Mode knob
Selects the delay mode.
Mode Explanation
STANDARD Clear digital delay.
ANALOG Mild analog delay.
TAPE Sound with the distinctive waver of a tape
echo unit. Models the Roland RE-201.
DRUM Models the Binson EchoRec2.
SHIMMER Delay that combines a pitch-shifted sound.
TERA ECHO Echo sound that is neither reverb nor delay,
with spaciousness and motion.
PAD ECHO Delay sound with a drifting feel.
PATTERN Sound that combines 16 delays.
LO-FI Fat sound with a sense of distortion.
DUAL Two delays connected in series.
DUCKING
The volume and feedback are automatically
adjusted according to the input. Won’t get in
the way of your performance even if applied
deeply.
REVERSE Delay that plays backward.
6 [PARAM] knob
Adjusts an appropriate parameter for each mode.
Mode Explanation
STANDARD Adjusts the sense of attack for the delay
sound.
ANALOG Adjusts the character of the delay sound and
the sense of distortion.
TAPE
Selects the combination of the three
playback heads.
If a decimal point “.” is shown for the lowest
digit, distortion is added to the sound.
DRUM
Selects the combination of the four playback
heads.
If all of the playback heads are combined,
the display indicates“ALL.”
If a decimal point “.” is shown for the lowest
digit, distortion is added to the sound.
SHIMMER Adjusts the brilliance of the delay sound.
TERA ECHO Adjusts the amount of distinctive character
for the eect sound.
PAD ECHO Adjusts the sense of attack for the eect
sound.
PATTERN Selects the pattern of delays.
LO-FI Adjusts the sense of distortion for the eect
sound.
DUAL
Adjusts the second delay time. This is
specied as a proportion (%) relative to the
rst delay.

Mode Explanation
DUCKING
Adjusts the sensitivity by which the volume
is automatically adjusted according to
the input. Increasing this value makes the
response more sensitive at lower volumes.
REVERSE Adjusts the sense of attack for the delay
sound.
7 [TONE] knob
Adjusts the tonal character of the eect sound.
When the knob is in the center position, the response is
at. Turning the knob toward the right boosts the high-
frequency range, and turning it toward the left cuts the
high-frequency range.
8 [MOD DEPTH] knob
Adjusts the depth at which the eect sound is
modulated.
9 [TAP DIVISION] button
Species the delay time in terms of a note length
relative to the BPM.
Preventing accidental operation (panel lock)
By long-pressing the [TAP DIVISION] button, you can
switch between enabling (unlocking) or disabling
(locking) operation of the knobs and buttons.
If you attempt an operation while the unit is locked, the
display indicates “LCK.”
10 TAP DIVISION indicator
This indicates the delay time as a note value; the
interval at which you press the pedal is considered as a
quarter note (100%)

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 and B jacks if connecting an eect unit that
has stereo output. Use only the A jack if using this unit
in mono.
Turning On/O the Power
The INPUT A jack also operates as the power switch. The
power turns on when you insert a plug into the INPUT
A 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 jack if using this unit in mono.
Even sound that is input in stereo is output in mono.
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 delay time or
switch memories (p. 10).

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 delay
time or the volume of the eect sound (p. 12).
* 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-seriesS) can be
connected to this jack.
* Use only the specied AC adaptor (sold separately: PSA-seriesS) 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
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 delay 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, FEEDBACK, E.LEVEL, PARAM, TONE, and MOD
DEPTH.
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)?
If you select “MAN,” the delay is heard using settings that
reect the actual positions of the knobs. The delay time
and TAP DIVISION use the settings that you wrote into
memory.

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” and Owner’s manual).
* “Lo” will appear on the display if the batteries are low. Replace them
with new ones.
