DIRECTIONS
• Connect included AC adapter into
the Iso-Brick Power Supply’s 18V
IN jack.
• Plug the AC adapter into a wall
outlet; the white power LED
will light.
• Connect up to six pedals requir-
ing 9V power to the six 9V OUT
jacks using the included barrel-
to-barrel cables. Be sure pedal’s
mA rating does not exceed
output’s indicated mA rating.
• Connect up to two pedals
requiring 18V power to the two
18V OUT jacks using the
included barrel-to-barrel cables.
Be sure pedal’s mA rating does
not exceed output’s indicated
mA rating.
• Two outputs provide controllable
voltage levels, from 6V to 15V.
Use VOLTAGE controls to adjust.

POWER
The Iso-Brick Power Supply
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. Comes with switchable
US/Japan, UK, EU, and
Australian plugs.
CONNECTION NOTES
• Included cables use industry
standard 5.5mm x 2.1mm posi-
tive barrel, negative center
polarity plugs.
• Each output features a blue LED.
When lit, this LED indicates a
good connection. If short-circuit-
ed or overloaded, this LED will
turn off.
• The Iso-Brick Power Supply has
six 9V outputs: two can handle
450mA, two can handle 300mA,
and two can handle 100mA.
• Two 18V outputs can handle
250mA each.
• Two variable 6V–15V outputs can
handle 250mA each.

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. Discon-
nect the cable from the output
whose blue LED is off. Wait 5 to
10 seconds for the unit to reset,
indicated when the blue LED
comes 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 Iso-Brick Power
Supply. Check by plugging the
power cable into a different
DC jack.
• Faulty jack on the pedal.
Test by running the pedal off
battery power.
ing 9V power, VOLTAGE controls
can be used to reduce power and
emulate the effect a dying battery
has on certain pedals. Note: Not
all analog pedals will operate be-
low 9V. Check with manufacturer
for operable voltage range. If your
pedal is sensitive to input volt-
age level, use a voltmeter to set
output voltage before connect-
ing pedal. Be sure pedal’s mA
rating does not exceed output’s
indicated mA rating.
WARNING: Some pedals may
be damaged if powered using
a voltage that exceeds the level
required by the manufacturer, e.g.
powering a 9V pedal with 15V or
18V. We highly recommend stay-
ing at or below manufacturer’s
state voltage requirement. Dunlop
assumes no responsibility or
liability for equipment damage
caused by misuse of the
Iso-Brick Power Supply.
• All outputs may be used simulta-
neously for a total power output
of 31.8 watts.
• Combining Outputs: Any output
may be combined with any other
output when stacked in series.
If combining outputs in parallel,
only outputs of the same voltage
may be used together.
• The Iso-Brick Power Supply’s
foldback current limiting circuit
(FCLC) provides ultimate protec-
tion against power shorts and
overloads. Even at full load, the
Iso-Brick Power Supply operates
coolly and quietly as a fully regu-
lated power supply.
