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.
