Connecting Earth
Your Mains Multiplier must be connected to an earthed wall socket, however if you do not
have earth the Mains Multiplier will still function. Even without an earthed wall socket the
Mains Multiplier itself will make a connection between all earth contacts of your
equipment. This will prevent that small currents will run through your interlinks due to
differences between earth potentials at your equipment’s chassis. So even without an
earthed wall socket you should keep using your earthed power cords.
On both the Mains Multiplier 6+ and Mains Multiplier 8+ you will find a tool which is unique
for Essential Audio Tools. It is called the
Ground Bridge
.
It consists of three terminals (one green, two black) which can be connected in two ways
by a bridge. With the Ground Bridge you are able to choose between the earth terminal in
your wall socket or an external earth you supply yourself. This external earth can be an
earth pole which you can have installed by a specialized company. The earth pole
(outside your house, deep in the ground) should have an exclusive connection to the
position where the Mains Multiplier 6+ or Mains Multiplier 8+ is. Nothing else should be
connected to this special earth pole. The Mains Multiplier’s green socket must be used to
connect your external earth.
Do not plug or unplug the Ground Bridge when the Mains Multiplier is powered!

In figure 5
you can see how the Ground Bridge is connecting the earth pin of the
wall socket with the earth connection inside the Mains Multiplier 6+ or
Mains Multiplier 8+.
In figure 6
you can see how the Ground Bridge is placed so the green socket can
be used for the external earth.
Please check the indicators, you should have two green lights. One green light means your
earth connection is not proper.
Tips
For maximum noise reduction, it is best to keep all power and audio cables in your setup
separated by some distance from each other and to avoid routing cables in parallel.
Use high-quality power cords (our Current Conductor for example) to connect your
equipment. The screening will prevent stray-fields to reach your audio cables. Order your
power cords as short as possible, for best results.
Do not connect distribution blocks or mains splitters to the outputs. It will possibly cause
interference.
Feed ALL your equipment from the Mains Multiplier. Having an extra external power feed
to one of your pieces of equipment will possibly cause interference and/or hum.
