LEVEL knob
This adjusts the volume of the eect sound. Clockwise rotation raises the volume
and counterclockwise rotation decreases.
7 The DS-2 is a distortion unit that features a turbo circuits.
7 All circuits adopt discrete system, therefore there is very low noisecreated.
7 Two types of distortions are optional by changing the Turbo Modes.
7 The turbo I/II can be controlled by using the footswitch connected to the Remote jack.
OUTPUT jack
Connect an amplier to this jack.
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.
* 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 accidentally disconnected from the unit.
* Use only the specied AC adaptor (PSA-series).
* If the AC adaptor is connected while power is on, the power supply is drawn
from the AC adaptor.
CHECK indicator
This indicator shows whether an eect is ON/OFF, and doubles as the Battery Check indicator.
The indicator lights when an eect is ON.
* If this indicator goes dim or no longer lights while an eect is ON, the battery is near
exhaustion and should be replaced immediately.
TONE knob
This adjusts the tone of the eect sound. As you rotate the knob clockwise,
higher frequencies are emphasized, and counterclockwise cuts them.
Pedal Switch
This switch turns the eects ON/OFF.
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.”

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” (supplied on a separate sheet).

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.

Batteries should always be installed or replaced before connecting
any other devices. This way, you can prevent malfunction and
damage.
