DC BRICK

DESCRIPTION
• Powers eight 9V pedals and two

18V pedals all at once without

sacrificing signal integrity

• Features 8 red LEDs to clearly

indicate short-circuited pedals

• Includes AC adapter and all

necessary cables to connect

pedals to the unit

DIRECTIONS
• Connect included AC adapter

into the DC Brick’s 18V IN jack.

• Plug the AC adapter into a

wall outlet; the blue power
LED will light.

• Connect up to eight pedals

requiring 9V power to the eight
9V OUT jacks using the included
barrel-to-barrel cables.

• Connect up to two pedals

requiring 18V power to the two
18V OUT jacks using the barrel-
to-barrel cables.

POWER

The DC Brick requires an 18V
regulated power supply rated at
2000 mA, with 5.5mm x 2.1mm
positive barrel, negative center
plug. The included power
adapter can utilize a wide range
of wall power, from 100-240V at
47-63Hz. Optional international
wall adapters can be ordered
from your Dunlop dealer.

CONNECTION NOTES
• Included cables use industry

standard 5.5mm x 2.1mm
positive barrel, negative
center polarity plugs.

• Eight 9V outputs can handle

an average of 150 mA each,
or a total of 1200 mA in
any configuration.

• Two 18V outputs can handle

an average of 400 mA each,
or a total of 800 mA in any
configuration.

• All outputs may be used

simultaneously for a total
current output of up to 2000 mA.

• The DC Brick is not compatible

with positive ground pedals.
Use of positive ground pedals
may cause short circuiting.

TROUBLESHOOTING

The power LED fails to light.

• Dead AC outlet. Try plugging into another outlet,

or test the outlet with another device like a lamp.

• Faulty connection. Double check plugs to

make sure they are inserted securely.

• Short circuited output. For 9V outputs

disconnect the cable from the jack whose
red LED is on. If no LEDs are on, disconnect
the cables from the 18V jacks. Wait 5 to 10
seconds for the unit to reset. This will be
indicated by the blue LED turning back on.

Power provided to some effects, but not others.

• Incompatible power plug. Check that the

dimensions and polarity of the pedals are
compatible with the provided cables.

• Faulty cord. Check by swapping the power

cable with another known good cable.

• Faulty jack on DC Brick. Check by plugging the

power cable into a different DC jack.
