CIOKS DC8
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.
After a long break three more units were introduced in 2007 forming our Standard range of
dedicated power supplies for effect pedals. The big breakthrough came in year 2010 where
we’ve released the first products of the professional range with the DC10 as the most popular
product. CIOKS became global with distributors and dealers worldwide. The DC8 was
launched in 2011 along with AC8 as new members of our professional range just with a bit
smaller size and price tag compared to DC10 –ideal for smaller pedal boards.
Features
•8 outlets configured in 6 isolated sections with a total current of 1.000mA
•2 powerful DC sections with 300mA each, able to power 2 higher current pedals like
Strymon, Eventide or tc electronic
•offers DC voltages 9 and 12V but also 18 and 24V with Stack Flex
•high efficiency toroidal transformer
•short circuit protection of all outlets
•advanced LED monitoring of each section
•compatible with Pedaltrain and Temple Audio pedalboards, mounting hardware incl.
Overview
Front
On the front of the enclosure you’ll find 8 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.
Top
On top of the enclosure you see the output voltage and max. current rating of each outlet
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. The bottom figure states the maximum current
capability of each outlet in mA. Outlets 3 and 4 with two possible voltage settings have both
values stated. 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 output section 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.

Back
In the space on the back of the enclosure you’ll find the AC power input socket, mains voltage
selector switch, fuse and the settings switch.
The AC power input socket is called C6 according to the IEC 60320 standard and it’s the same
type used in many laptop power supplies.
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 can be replaced by the user. In case it’s blown, replace with a
5x20mm, T315mA (slow blow/time lag) type.
The settings switch should be used for changing the operation settings of the power supply.
Bottom
The four detachable rubber feet are situated on the bottom of the enclosure. On this same
surface you’ll find a table showing the different settings of the power supply, which you select
using the settings switch on the back. Also here are the 6 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 wall
outlet. 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. Rock’n’Roll..! ...or JaZz!
Settings
To change the settings of the power supply you use the settings switch on the back of the
enclosure. In the table below you can see the different settings:
No.
Function
Switch OFF (down)
Switch ON (up)

Outlet 3

Voltage settings
Voltage of outlets 3 and 4 can individually be set to 9 or 12V with switch knobs no. 1 and 2,
where the default value is 9V.
Features
Advanced LED Monitoring
Each isolated outlet or section has its individual LED status indicator. The indicator is lit in
normal operation. Its light gets dim when you operate just on the edge of the current limit. If
you overload or short circuit an outlet, the respective LED indicator turns off.
The LED indicators of outlets 3 and 4 with selectable output voltages 9 or 12V, also show you
the voltage chosen with 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. Default setting for outlets 3 and 4 is 9V and the higher value is 12V
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 and 120V in e.g. United States. 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 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.
Included accessories
Flex cables
CIOKS offers a great selection of different Flex cable types for connecting your pedals to the
power supply. Below you see a list of the included Flex cables with your unit:
Type 1 –black with 5,5/2,1mm centre negative DC-plug x5
Type 2 –red with 5,5/2,1mm centre positive DC-plug x1
Type 4 –green with 5,5/2,5mm centre positive DC-plug x1
Type 5 –black with 3,5mm tip positive jack-plug x1
Type 6 –black with 9V battery clip x1
Split Flex type 1 –black with two 5,5/2,1mm centre negative DC-plugs x1
Stack Flex type 1 –black with 5,5/2,1mm centre negative DC-plug x1
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
More Flex cables and Booster Flex
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 order them 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 or in the included Flex guide.
They really open up for even more versatility and flexibility in terms of what you can power
with your unit.
