IT IS YOURS!
Thank you for purchasing Lab12 gordian. Gordian is an advanced power analyzer, conditioner and
distributor dedicated for high-end audio systems.
Keep in mind that gordian is totally handcrafted with perfectly matched parts of the finest selections. OFC
Conductors of large cross section, star ground design, high quality tight sockets and industrial grade
bindings constitute the unshakable electrical network that delivers power to your system.
Before setting up your new gordian, we encourage you to read this manual thoroughly to properly
acquaint yourself with its features.
The information contained in this manual is subject to change without notice. The most current version of
this manual is available on our official website at http://www.lab12.gr
Unpacking
Lab12 gordian removal from its box should be handled with care. You should first remove all the foam
protective pieces of the box and then unpack gordian. Unpack gordian placing your hands on both sides
of the device.
Warnings
No user serviceable parts are included inside. Do not unscrew the cover; high voltages remain after
disconnecting from mains. In case your device requires any kind of service, please ship or take your
equipment directly to Lab12 or to one of our authorized dealers or other qualified personnel.
Installation & Placement
Gordian should be placed on a solid flat surface. You should avoid placing it near a heat source as this
could compromise the performance and reliability. You should never place another component directly
on top of this device. Make sure that your gordian has an adequate flow of air around it. Gordian could be
warm in some points; this is normal and within parts specifications. Take care of the front panel’s glass
blasting anodized finishing using a soft dry cloth.

Menu structure
All the information for your power line and the configuration of gordian's filter is accessible and
updatable through the device's OLED display. You can switch among 11 different menu screens using the
"Navigation" rotary/push knob on the left of the face plate. Rotate the knob to navigate through the
menu and push it to perform any extra action. See below a brief description of the available menu items.

Ground and
polarity check
Checks your socket’s ground and
polarity.
Switch off gordian and invert the direction of
your wall socket plug if you see a "Polarity:
REV!" message. This is the best for the
performance and safe operation of your
devices.
If you see a "Ground: Broken!" or "Ground:
Weak" message this means that gordian has
detected a problematic ground connection.
Check that your socket plug is firmly
connected. If the message remains, then you
may need to refer to qualified personnel to
have your house's electrical network
inspected.
5

Power factor correction configuration
The power factor of your audio system indicates how effectively your system absorbs power from your
main AC line. The higher the power factor, the higher the effectiveness of your system's power
consumption. You can inspect the power factor of your system at the menu item 8.
WARNING! The power factor of your system may be improved by selecting the proper power factor
correction configuration in gordian. However, if the configuration is not the proper one, this may have
negative results in your system’ s power factor. If you are not sure about what is the best option for your
system, set the PF correction mode to 'AUTO' and let gordian adapt the PF correction to the needs of
your system and the variations of your system's load. Note that PF correction is usually profitable for
power loads greater than 250W.
EMI noise filter configuration
EMI noise is a high frequency electrical noise that affects the power line of all houses’electrical networks.
You can see the level of the EMI noise in the input of gordian at the menu item 5.
Gordian, by default, filters a very large percentage of the EMI noise of your line. This noise reduction is
occurred in both the input and the output of your gordian power filter. That means that the noise
indication you see in the OLED display is the result of the filter existence in your house's electrical
network. However, the noise level in gordian's output is always lower than the input's level. EMI
indication is factory set to output measurement.
You can fine-tune the EMI filter by configuring the "Filter Effectiveness" (menu item 9) and "Filter
Topology" (menu item 10) parameters. Feel free to experiment with these options and stuck to the one
that gives you the best sounding result.
In general, "HIGH" Filter effectiveness and "CMF + DMF" filter topology are the more drastic ones. You
can take into account the measured EMI level (menu item 5) and the higher band levels of your system's
current frequency analysis (menu item 7) to decide on the best filtering configuration.
If you are not sure on what configuration to select, choose "AUTO" and let gordian automatically adapt
the filter configuration by mathematically analyzing the frequency content of the signal and the levels of
the EMI noise.

Operation modes
On : Gordian’s processor is always active and you can see the measurements, settings and automatic
adjustments on the OLED display.
Sleep : Gordian’s processor and OLED display are inactive. Power output sockets are active, but no
changes are occurred on filters and other settings.
Auto : Gordian processor goes to active state only when the standby current exceeds the set value.
You can configure the operation of gordian's processor with the rotary switch on the right side of the face
plate. If you want the processor to be always active, switch the knob to the "On" position. If you want the
processor to be in sleep mode (output sockets will stay alive), switch the knob to the "Sleep" position. If
you want the gordian processor to become active only when your audio system is active and
automatically go to sleep when you switch off your system then you have to configure the "stand by"
current of your system and switch the knob to the "Auto" position.
To configure the "stand by" current, shut down all your system's devices and navigate to the standby
current setup (menu item 11). Press and hold the navigation button and gordian will store the current
consumption of your inactive system. Rotate the operation mode switch to the "AUTO" position and the
OLED display will now become active only when your system's current consumption is great enough to
indicate that your system is active.

Connections
Main connections
Connect a high grade 20A power cable to the IEC input and to your wall socket. Make sure that your
wall socket provides a good ground before connecting the power cable. You can supply 230 to 240
Volt AC/ 50Hz (115 to 120 AC Volts / 60Hz). Check the polarity immediately after the first time of
usage and correct the wall plug if needed.
Gordian is tuned and calibrated using the Lab12 Knack mk2 Power Cable. We strongly suggest using
this cable.
Connect devices
You can connect any kind of audio-video devices on the total six power outlets on the back panel
of gordian to exploit the conditioned power. Use low filtered outputs (B) to connect high current
devices (power amplifiers, plasma tv etc.) and high filtered outlets (A) for low consumption devices
(preamplifiers, cd players, DACs etc.). Live (phase) connection is always in the right pin of each
outlet. Never exceed the maximum limits of current for low and high filtered outlets (low filtered
outlets max 15A, high filtered outlets max 4A).
For the safety of your equipment
! Make sure that all your equipment is turned off before any connection.
! Never exceed the maximum limits of current for low and high filtered outlets (low
filtered outlets max 15A, high filtered outlets max 4A).
