INTRODUCTION
Thank you for purchasing Applied Research and Technology’s
ISO-8U.Two high power outputs can provide 250mA. All other
outputs are capable of providing up to 100mA. There is one
variable voltage output to simulate worn batteries.
Each output is individually current limited and short circuit
protected. An Output status indicator goes out when there is a
fault (i.e. short, current protection or temp overload).
A USB type A jack can provide high power charging up to
10Watts.
The unit comes with a wide variety of cables to connect your
pedals including battery clip adapters, large and small diameter
power plugs, and “Y” for expanding the number of devices you
can connect and even a polarity reversing cable.
FEATURES
• Eight Isolated DC Outputs
• One Adjustable Output
• Each Output Has a switchable voltage
• USB Power jack for high speed charging
• Comes with multiple adaptor cords
• Runs off a Universal power supply
• Tie wrap slots for clean wire routing
• Perfect for powering guitar pedals, and pedal boards
• Designed and developed in the USA

INSTALLATION and OPERATION

3
Status LED’s
These LED's remain lit as long as there are no electrical faults
with the cabling or the pedal you are supplying power too. If a
particular fault seen at one of the outputs, the LED dim or turn
off and the voltage at that output will diminish. The cable
connection on the output with the fault will have to be removed
and reconnected for the output to be reset.
SAG Voltage
To enable this function on voltage output1 the dip switch will
need to be set to 4-9v. Then the user can vary the voltage from
the pot on the unit face.
APPLICATIONS
The ART ISO-8U is designed so that it can be mounted on a
pedal base using Velcro. The front and sides are recessed to
protect the cables and controls.
The bottom edge of the ISO-8U has slots that allow you to use
cable ties to control the routing of the power cables. Once you
loosely insert the wire ties through the slots you can run the
power cables through the remaining loops. Once all of the
cables are in place, you can tighten down the wire ties.

Powering your Pedals
The first step in using the ART ISO-8U to power your device,
would be to make sure that pedal device you want to use can
be powered by a dc supply. The range on the ART ISO-8U is 9
or 12vdc or combining to outputs to achieve 18 or 24vdc,
remember that there is a max current draw on each output.
Then verifying the polarity of the pedal device you are wanting
to power. Generally, 9V battery powered devices will draw less
that 100mA.
The ART ISO-8U uses the negative center pin configuration.
This will determine if you need to use the polarity
reversal cable or one of the standard cables. This
will allow you to use a pedal that has a positive
center pin. Before you connect the cable from the
unit, make sure you set the dipswitch to the appropriate voltage
(9v or 12v).
If you have a pedal device that does not have a power jack
and is powered by a 9V battery, then you can use the cable
that has the battery tab connector.
There is a limitation on current loading, as this unit is not
meant to run all of the outputs at their maximum current draw.
