Introduction
Pedal Power ISO-5 is an isolated power supply for powering guitar pedal effects
and accessories. Its compact design is perfect for smaller pedalboards, rack
shelves, or even as an additional power supply for larger boards. Pedal Power
ISO-5 features five independent, filtered and regulated output sections, which will
keep even the most sensitive vintage and boutique analog pedals dead quiet.
Pedal Power ISO-5 includes a high-current output which will properly power
modern digital power-hungry effects like those from Eventide, Line 6, and TC
Electronic. There’s also a dedicated 18V output for those pedals which need the
higher voltage for extra headroom.
Designed to meet the needs of professional users, Pedal Power ISO-5 will
provide clean, consistent power, even with the poor AC line conditions often
found on stage. Completely isolated output sections eliminate ground loops and
unwanted interactions between effects, resulting in lower noise and noticeably
improved tone.
All Voodoo Lab products are engineered and handmade in the U.S.A.
Unpacking
Your Voodoo Lab Pedal Power ISO-5 box should contain the following:
Pedal Power ISO-5 unit
Warranty card
AC line cord
DC Power cables:
5.5x2.1mm right angle barrel connectors (4)
5.5x2.1mm right angle to straight barrel connector (1)
5.5x2.5mm right angle “red” barrel (1)
3.5mm right angle mini plug (1)
Connections
Pedal Power ISO-5 is powered directly from mains using the supplied AC line
cord. This is a standard computer-type IEC line cord, so it’s easy to obtain a
replacement or different length.
Important: Pedal Power ISO-5 is manufactured to operate from a specific supply
voltage (100V, 120V or 240V) which is marked on the bottom of the unit.
Attempting to operate at the wrong voltage without the correct step-down
transformer may cause permanent damage.
1) 9V outputs (3). Use for all ordinary pedals which operate from a 9V battery or
require less than 100mA.
2) 9V high-current output. Use for devices which require up to 300mA. These
effects will use multiple 1.5V batteries or a 9V regulated adapter (wall wart). This
output can also power ordinary low current pedals.
3) 12V high-current output. Use for all devices which require 12V at 300mA or
less. Most devices that use a 9V unregulated adapter should be powered from
this output.
Note: The 9V and 12V high-current outputs are not isolated from each other
(their negative terminals are common). It is preferred to use only one. If using
both, combined output should not exceed 300mA.
4) 18V output. Use for 18V pedals which operate from two 9V batteries or require
less than 100mA. Do not power 9V effects at 18V unless recommended by the
manufacturer.
DC Power Cables
The Pedal Power end of each supplied DC power cable has a black barrel
connector. The other end has either another identical barrel connector (center
negative), a 5.5x2.5mm red barrel (center positive) or a 3.5mm mini-plug (tip
positive). Use the standard right-angle black barrel connector cables with most
common 9V battery operated pedals. Occassionally, a right-angle connector will
not properly fit the power jack, so a cable with straight connector is also provided.
Before powering your pedal with a standard black barrel connector, you must
verify that the pedal requires “center negative” polarity to prevent damage. Some
common exceptions with their power jacks wired for “center positive” are the
Fulltone ‘69, SoulBender, and Octafuzz pedals and Moogerfoogers. Reverse
polarity cables are available from Voodoo Lab to properly power these pedals.
Boss Pedals
There are two types of Boss pedals which operate from a 9V battery. These are
identified by the type of power supply specified, either PSA or ACA. Almost all
Boss pedals specify the PSA type adapter and operate at 9V. Boss pedals which
specify the ACA type adapter require a higher voltage and should be powered by
the 12V output.
Boss Twin pedals, such as the DD-20 (which require more than 100mA), should
be powered from the 9V high-current output.
Line 6 Modeling Pedals
Line 6 Tone Core pedals and Pocket POD can be powered from any available 9V
output using a standard black 5.5x2.1mm barrel cable.
You can power Line 6 modeling pedals, like DL4 or MM4, using the 12V highcurrent
output with the red 5.5x2.5mm barrel cable.
Note that PODxt, M13 and JM4 looper cannot be powered by the Pedal Power
ISO-5.
TC Electronic
TC Electronic’s Nova pedals such as the Delay, Modulator and Reverb are
powered from the high-current 12V output using a standard black 5.5x2.1mm
barrel cable. Other TC Electronic pedals which can be powered from a 9V
battery, such as the Classic series, can operate from any of the 9V outputs.
Eventide
The Eventide stompboxes (TimeFactor, ModFactor and PitchFactor) are
powered from the high-current 12V output using the red 5.5x2.5mm barrel cable.
Additional Cables
The DC power cables supplied with your ISO-5 are suitable for most common
pedal effects. If you need additional cables, different lengths, reversed polarity, or
a special connector, these are available from Voodoo Lab.
Isolation
Pedal Power ISO-5 has has five isolated output sections. This is sometimes
referred to as “galvanic isolation” and means that there is no direct electrical
connection between each output. Similarly, when you power your effects with
batteries, they are also isolated because there is no electrical connection
between the batteries.
Most power supplies are not isolated. Their output jacks are simply bussed
together or use a daisy chain cable. This allows unwanted electrical current to
flow between the outputs, commonly called a ground loop. The result is added
noise. The isolated outputs of Pedal Power ISO-5 eliminate this noise.
Another benefit is that you can power both negative ground and positive ground
effects with Pedal Power ISO-5. Negative ground effects are by far the most
common, however the Fuzz Face and Octavia are some well known examples of
positive ground circuits. Attempting to power positive ground pedals together with
negative ground pedals from a non-isolated power supply will not work and may
even damage the supply.
There are a couple of other tricks you can get from an isolated supply like Pedal
Power ISO-5. You can use a special Y-cable which connects two 9V outputs in
series to get an additional isolated 18V out. Occassionally, a pedal requires a
bipolar supply, using two batteries for +9V and -9V. Isolated outputs work fine for
this, non-isolated supplies do not.
