Getting Ready
Installing the Batteries
Install four alkaline batteries (AA, LR6) in the battery compartment located on the bottom of the
unit.
* 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”(separate sheet “USING THE UNIT SAFELY” and Owner’s manual (p. 26)).
* 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 accidently disconnected from the unit.
* To prevent malfunctions or accidents, install or replace the batteries before connecting the unit
to other equipment.
* “BATTERY LOW” will appear on the display if the batteries are low. Replace them with new ones.
Attaching the Rubber Feet
You can attach the rubber feet (included) if necessary.
Attach them in the locations shown in the illustration.
Connecting the Equipment
* To prevent malfunction and equipment failure, always turn down the volume, and turn o all
the units before making any connections.
* Be sure to minimize the volume of your amp before you connect or disconnect cables.
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.
* Use only the specied AC adaptor (PSA series; sold
separately), and connect it to an AC outlet of the correct
voltage. Do not use any other AC adaptor, since this may
cause malfunction.
* If the AC adaptor is connected while power is on, the power
supply is drawn from the AC adaptor.
USB (O) port
Use a commercially available
USB 2.0 cable to connect this
port to your computer.
You can synchronize with a
DAW via MIDI.
MIDI IN, OUT connectors
Connect an external MIDI
device here.
You can synchronize with
an external MIDI device

Getting Ready
CTL 1 ,2/EXP jack
You can control various parameters by connecting a footswitch (FS-5U, FS-5L, FS-6, FS-7: sold separately) or an expression pedal (such as
the Roland EV-5: sold separately) to the CTL 1, 2/EXP jack (p. 22).
INPUT A/MONO, B jacks
Connect your electric guitar, or another
instrument or eect unit, to these jacks.
* Use the INPUT A/MONO jack and B jack
when connecting a stereo-output eects
unit. Use only the INPUT A/MONO jack if
you’re using a mono source.
* The INPUT A/MONO jack doubles as
the power switch. Power to the unit is
turned on when you plug into the INPUT
A/MONO jack; the power is
turned o when the cable is
unplugged.
OUTPUT A/MONO, B jacks
Connect these jacks to your amp or monitor speakers.
If you’re using a mono setup, use only the OUTPUT A/MONO jack.
* Do not connect headphones to the OUTPUT A/MONO, B jacks.
Doing so may damage the headphones.
When connecting EV-5
EXP
* Use only the specied
expression pedal (EV-5; sold
separately). By connecting any
other expression pedals, you
risk causing malfunction and/
or damage to the unit.

Getting Ready
Turning the Power On
* Once everything is properly connected (p. 2), be sure to follow the procedure below to turn
on their power. If you turn on equipment in the wrong order, you risk causing malfunction or
equipment failure.
1. Insert a plug into the INPUT A/MONO jack.
The DD-500 power turns on.
2. Turn on the power of your guitar amp or other equipment.
* This unit is equipped with a protection circuit. A brief interval (a few seconds) after turning the
unit on is required before it will operate normally.
* 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 turning the power o, do so in the reverse order.

Convenient Functions
Specifying Whether to Carry-Over the Delay Sound
You can specify whether the eect sound is carried-over (ON/OFF) when you switch patches or
turn the delay o.
1. Press the [EDIT] button.
2. Use the [H] [I] buttons to select “PATCH,” and then press the
[EDIT] button.
3. Use the [H] [I] buttons to select “CARRY OVER,”and use the [TIME/
VALUE] knob to select ON / OFF.
4. Press the [EXIT] button to return to the top screen.
Assigning the Functions of the [A], [B], and [TAP/CTL] Switches
1. Press the [EDIT] button.
2. Use the [H] [I] buttons to select “SYSTEM”and then press the
[EDIT] button.
3. Use the [H] [I] buttons to select “FSW MODE,” and use the [TIME/
VALUE] knob to select the mode.
Mode Explanation
NORMAL
Use the [A] and [B] switches to select patch A or patch B, and use the [TAP/CTL]
switch for tap input.
* If you want to use the [TAP/CTL] switch as the CTL, set the “TAP/CTL FUNC”
to “CTL” (p. 8).
A/B/C Use the [TAP/CTL] switch to select patch C.
* In this case, you can't use the [TAP/CTL] switch for the TAP or CTL functions.
A/B SIMUL Patches A and B can be used simultaneously. Press the unlit [A] or [B] switch to
make both light.
SW DN/UP Use the [A] switch to turn delay on/o, and use the [B] switch and [TAP/CTL]
switch to change patches.
4. Press the [EXIT] button to return to the top screen.

Synchronizing with a DAW or External MIDI Device
You can synchronize your DD-500 performance with a computer or an external MIDI device by
sending and receiving MIDI messages.
For example, an external MIDI device or DAW could switch patches on the DD-500 or control its
tempo.
