Basic Operation
Connect included AC adapter into M239’s 18V INPUT jack.
Plug AC adapter into wall outlet; white INPUT LED indicates
good connection.
Connect up to four pedals requiring 9V power to the four 9V
OUT jacks using the included barrel-to-barrel cables.
Connect another pedal to the switchable 9V/18V output. Use
9V/18V slide switch to match pedal voltage (indicated by green
LED).
Included splitter cable can be used to connect two pedals to a
single output. Connect straight end to M239 output and right-
angle ends to pedals’ power inputs.
Whether connecting single pedal or multiple pedals via splitter
cable, always be sure pedal mA ratings do not exceed output
mA ratings.
WARNING: Some pedals may be damaged if powered using
voltage that exceeds level required by the manufacturer, e.g.
powering a 9V pedal with 18V. We highly recommend staying
at or below manufacturer’s stated voltage requirement. Dunlop
assumes no responsibility or liability for equipment damage
caused by misuse of M239.
The Mini 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.
