Mounting hardware
We’ve included all the needed hardware to mount the power supply on top or underneath a
Pedaltrain or Temple Audio pedalboard. You can of course also attach it to boards of other
brands. Look on CIOKS web site for more information and mounting guides.
Not included accessories
Mains Link Adapter or Mains link cable
This adapter or cable type allows you to link two or more of the link power supplies together
and power several units using one single mains power cord.
Mains Adapter – universal
This mains adapter is available as a kit incl. mounting hardware to secure the connection. It
converts the IEC C13 mains outlet into two universal wall type mains outlets (one EU/US/UK
type and one EU/US type) allowing you to connect two adapters of the plug-in type or any
other mains powered appliances of your choice to it and power them via the courtesy outlet.
More Flex cables
To power one pedal using one outlet you simply use a single suitable standard Flex cable and
that’s it. In case the plug type or length you need is not included with your unit there’s a big
selection of standard Flex cables to choose from and to be ordered separately. In case of an odd
voltage or current requirement you might need one of the Special Flex cables available. Please
read more about these and how to use them on CIOKS web site. They really open up for even
more versatility and flexibility in terms of what you can power with your unit.

CIOKS Big John link
Power Supply for Effect Pedals
User’s Manual
reversion 1.1 – March 2017
Introduction
Since 1991 the Danish company CIOKS has been providing guitar and bass players with
reliable power supplies dedicated for effect pedals. After our very first product CIOKS Baby
power supply was out in 1991, the Big John and Double Jack were launched in year 1995.
Three more units were introduced in 2007 forming our Standard range of dedicated power
supplies for effect pedals.
To follow our slogan "More power, more features, more design", we have in 2013 launched
CIOKS link range. Three of the Standard range products have been dramatically upgraded and
went through a spectacular face-lift, where the only thing left are their original names. CIOKS
Schizophrenic link, Big John link and AC Rider link were our new babies in year 2013. Small
size, yet very powerful and each model with an individual character and force. The unique
mains link feature allows you to merge two or more power supplies giving you the possibility
to create a power supply bank matching your individual needs. Just one single mains power
cord will power two or three power supplies, where you always have a courtesy AC mains
outlet available on the last unit. You can of course also use them as standalone power supplies,
getting just one to start with and extend with time.
CIOKS Big John link has its 6 outlets configured in 4 isolated sections. The first four outlets
are divided in two isolated sections, which yield 100mA each and offer voltages 9 and 12V.
The last two isolated high current outlets put out a max. current of 400mA each at voltages 9 or
12V.
Features
• 6 outlets configured in 4 isolated sections
• two high current outlets with 400mA each
• short circuit protection of all outlets
• advanced LED monitoring of each section
• 120 or 230V mains voltage operation
• detachable mains power cord
• courtesy AC mains outlet
• CIOKS unique mains link feature
• 9 Flex cables included
• very easy mounting with pedalboards, all needed hardware included
• compatible with Pedaltrain and Temple Audio pedalboards

Overview
Front
On the front of the enclosure you’ll find 6 outlets of the power supply as RCA sockets which
all are centre positive. Correct polarity for the pedal is achieved by using the right Flex cable.
The red settings switch with four white knobs placed just to the right of the outlets should be
used to set the output voltage of outlets 2, 4, 5 and 6. The very left knob is for setting of outlet
2, the second for outlet 4, third for outlet 5 and finally the last knob should be used to set
output voltage of outlet 6.

Top
CIOKS logo has a red LED placed in the middle of the letter ‘O’. When this LED is lit the
power supply is connected to mains and operates.
On top of the enclosure you see the output voltage and max. current rating of each outlet or
section printed just above the outlet sockets. The top figure is the voltage and the DC in the
middle line tells you it’s a direct current outlet. Outlets with two possible voltage settings 9 or
12V have both values stated as 9/12. Bottom figure states the maximum current capability of
each outlet in mA. Isolated sections with two outlets sharing the same GND have one common
figure for maximum total current which can be put out from both outlets in the section.
The status of each isolated section or output is shown by a LED indicator also situated on top
of the enclosure just above the voltage figure. The function of this advanced and unique
monitoring feature is described in detail later on.
Left side
On the left side of the enclosure you’ll find the AC power input connector, which is a C6 type
according to the IEC 60320 standard also used in many laptop adapters. On the same side as
the AC mains input you’ll find the mains voltage selector switch and the fuse.
Mains voltage selector switch should be used for setting the correct mains voltage 115 or
230V. The Japanese version is made only for a 100V nominal mains voltage and has no mains
voltage selector switch.
The fuse is the only part which may be replaced by the user. In case it’s blown, replace with a
5x20mm, T 315mA (slow blow/time lag) type.
Right side
On the right side you’ll find the AC mains courtesy outlet connector, which is a C13 type
according to the IEC 60320 standard. The current drawn from this outlet should not exceed 2A.
Bottom
The four detachable rubber feet are situated on the bottom of the enclosure. On this same
surface you’ll find 5 holes with metric M4 threads, which should be used for easy mounting of
the power supply to a pedalboard. Do not use screws, which would go further than 5mm inside
the unit. Have a look at the mounting guide on CIOKS web site.
Getting started
First make sure that the voltage value chosen on the voltage selector switch matches the mains
voltage in your wall socket. Connect the mains power cord to the power supply and mains.
Using the right Flex cable types connect your pedals to the outlets of power supply making
sure that the voltage and current is correct for every pedal.
Advanced LED Monitoring feature
Each isolated outlet or section has its individual LED status indicator. The indicator is fully lit
in normal operation of a particular outlet. Its light gets dim when you operate just on the edge
of the current limit. If you overload or short circuit an outlet or section, the respective LED
indicator turns off.
The LED indicators of outlets 2, 4, 5 and 6 with selectable output voltages 9 or 12V, also show
you the voltage set by the settings switch. In case a higher voltage than the default 9V setting is
selected for a given outlet, its respective LED indicator will be lit with higher intensity than the
other indicators.
All indicators take into account the actual level of mains voltage when monitoring a possible
overload. The current limits for each outlet or section of the power supply are specified at
nominal level of the mains voltage. In Europe it’s 230V, 120V in e.g. United States and 100V
in Japan. If the mains voltage is higher than nominal, you can draw more current from the
power supply than stated in the specifications. This would never be a problem. A more
common situation though, is when the mains voltage is lower than nominal. In such a case
maximum current ratings for each outlet or section might be diminished.
The advanced LED monitoring of each isolated section or outlet will alert you in case of an
overload or short circuit. If such a situation happens you know where to look to solve the
problem. A glance at the LED status indicators and you have proof of 100% clean power to
your pedals.
