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.

● 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.
