Unpacking
LAB12 Gordian should be removed from its box with care. Remove all the polystyrene protective pieces
of the box before you unpack Gordian. Unpack Gordian with 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.
Always use same type of fuse for replacement.
Installation& Placement
LAB12 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
finest luxury finishing using a soft dry cloth.

4
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
EMI noise
Measurement of the EMI noise of your
line (frequencies > 10.000 kHz).
-
6
Voltage FFT
Frequency analysis of your line’s
voltage. Inspect here the frequency
content of you AC voltage signal
(frequency range 50Hz-7kHz).
Push the rotary knob to inspect the frequency
content of your voltage signal. You can see the
gain of each frequency band by rotating the
knob.
Push again to go back to the main menu
navigation.

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 systems power factor. If you are not sure on 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 300W.
EMI noise filter configuration
EMI noise is high frequency electrical noise that affects the power lines of all the 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.
The noise level in Gordian's output it is usually lower than the input's level.
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's 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.

Display modes
You can configure the operation of Gordian's OLED display with the rotary switch on the right side of the
face plate. If you want the OLED display to be always active switch the knob to the "ON" position. If you
want the OLED display to be always inactive switch the knob to the "OFF" position. If you want the display
to become active only when your audio system is active and automatically switch off 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 12). Press and hold the navigation button and Gordian will store the current
consumption of your inactive system. Rotate the display 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 Volts AC (50Hz). Check polarity immediately after first time use and correct wall plug if needed.
Gordian is calibrated and tested connected with a Lab12 Knack 20A power cable. We strongly
suggest to use 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 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 of 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.
