Thank you, and congratulations on your choice of the BOSS DD-7 Digital Delay.

Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and

“IMPORTANT NOTES” (supplied on a separate sheet). These sections provide important in-

formation concerning the proper operation of the unit.

Additionally, in order to feel assured that you have gained a good grasp of every feature pro-

vided by your new unit, this manual should be read in its entirety. The manual should be

saved and kept on hand as a convenient reference.

A battery is supplied with the unit. The life of this battery may be limited, however, since

its primary purpose was to enable testing.

Main Features

●

Achieves long delay times of up to 6.4 seconds. (*1) What’s more, up to 40 seconds of

loop play—or “sound on sound”—is possible in HOLD mode.

●

Multiple delay modes include “MODULATE,” which adds a chorus effect to the delay

sound, and “ANALOG,” which models the classic BOSS DM-2 analog delay pedal.

●

Features two new stereo modes in addition to 2-in/2-out true stereo connections.

●

Provides stereo effects like “Panning” and “Effect + Direct.”

●

Parameters can be controlled using an optional expression pedal (Roland EV-5).

●

The delay time can be set in realtime by pressing an optional footswitch (FS-5U) or the

built-in pedal to input the tempo.

(*1) The delay time that can be set varies according to the mode.

1. AC Adaptor Jack

Accepts connection of an AC Adaptor (PSA-

series; optional). By using an AC Adaptor,

you can play without being concerned about

how much battery power you have left.

* If there are batteries in the unit while an AC

adaptor is being used, normal operation will

continue should the line voltage be interrupted

(power blackout or power cord disconnection).

* Use only the specified 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

This is a combination indicator, which indi-

cates whether the effect is on or off, indicates

the various functions (p. 12–20), and func-

tions as the battery check indicator.

The indicator lights when an effect is ON.

Panel Description

* If this indicator goes dim or no longer lights

while an effect is ON, or when the functions are

indicated, the battery is near exhaustion and

should be replaced immediately. For instructions

on changing the batteries, refer to “Changing

the Battery” (p. 22).

* The CHECK indicator shows whether the effect

is on or off, and indicates the different functions.

It does not indicate whether the power to the

device is on or not.

3. OUTPUT-A (MONO) Jack

OUTPUT-B Jack

The output jacks are used to connect the unit

to an amplifier or another effects unit.

* The unit’s functions differ according to how it is

connected. Refer to “Setting the Output

Method” (p. 16).

4. INPUT-A (MONO) Jack

INPUT-B Jack

These jacks accept input signals (coming

from a guitar, some other musical instru-

ment, or another effects unit).

* The unit’s functions differ according to how it is

connected. Refer to “Setting the Output

Method” (p. 16).

* The INPUT-A (MONO) and INPUT-B jacks

double as power switches. Power to the unit is

turned on when you plug into the INPUT-A

(MONO) or INPUT-B jack; the power is turned

off when the cable is unplugged. Be sure to

disconnect any cord plugged into the INPUT-A

(MONO) or INPUT-B jack when not using this

effects device.

5. TEMPO/EXP Jack

This jack is for connecting an optional external

footswitch (FS-5U) or an optional expression

pedal (Roland EV-5).

DD-7_e.book 5 ページ２００８年３月７日　金曜日　午前１１時１８分

Panel Description

You can make tempo settings using a foot-

switch or manipulate various parameters us-

ing an expression pedal.

* Refer to “Setting the Tempo Using an External

Footswitch” (p. 13), “Control Using an

Expression Pedal” (p. 20).

6. Pedal Switch

This is used for switching the effect on and

off, and for switching between the different

functions (p. 12–15).

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. 22).

8. E.LEVEL (Effect Level) Knob

This adjusts the volume of the effect sound. Turn

the knob clockwise to increase the effect sound.

When set at the three o’clock position, the effect

is played at the same volume as the direct sound.

* When the E.LEVEL knob is set to MAX while in

REVERSE mode, only the effect sound is

output, with the effect sound at the same level as

the input sound.

9. F.BACK (Feedback) Knob

This adjusts the feedback level. The number

of times the delay sound is repeated increas-

es as the knob is turned to the right.

* This cannot be used in HOLD mode.

* Oscillation may occur when the knob is set at

certain positions.

10.D.TIME (Delay Time) Knob

This adjusts the delay time. Turning the knob

clockwise lengthens the delay time.

* This cannot be used in HOLD mode.

* The delay times that can be set vary according to

the position of the MODE knob.

11. MODE Knob

This switches the delay effect.

●

Ordinary Delay

* The delay time is doubled when the DD-7 is

connected for long delay output. For more infor-

mation, refer to “Long” (p. 17).

Specialized Delays

*1 In HOLD mode, the maximum recording

time is 20 seconds for stereo input or 40

seconds for monaural input.

* The delay time is doubled when the DD-7 is

connected for long delay output. For more infor-

mation, refer to “Long” (p. 17).

HOLD:

This records up to 40 seconds of a perfor-

mance (when using monaural input),

then plays it back repeatedly.

* For details, refer to “Using the HOLD

(Overdubbing) Function” (p. 15).

MODULATE:

This produces a pleasant chorus effect by

adding a small amount of undulations to

the effect sound.

ANALOG:

The sound changes progressively with

each repetition of the repeat sound.

This tone is modeled on the BOSS “DM-2”

Compact Delay.

REVERSE:

This delay produces an effect like playing

back a tape in reverse.

You can adjust the E.LEVEL knob setting

to get two different kinds of effect, “Effect

Sound + Direct Sound” and “Effect Sound

Only.” Turning the E.LEVEL knob com-

pletely to the right switches this to “Effect

Sound Only.”

Connections

* When running the unit on battery power, inserting a plug into the INPUT-A (MONO) or INPUT-B jack

will automatically switch the unit on.

* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required

before the unit will operate normally.

* The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you

prefer to use batteries, please use the alkaline type.

* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and

turn off the power on all devices before making any connections.

* Some connection cables contain resistors. When connection cables with resistors are used, the sound level may be

extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

* If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should

the line voltage be interrupted (power blackout or power cord disconnection).

* Once the connections have been completed (p. 9), turn on power to your various devices in the order

specified. 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 off the power to your guitar amp

first

* 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.
