Thank you for purchasing this Essential Audio Tools Mains Multiplier!
‘Essential Audio Tools’ is a Square Audio brand name. The name speaks for itself, tools
which are very essential for music reproduction. Better reproduction often means more
involvement.
Our ‘Essential Audio Tools’ are products to improve the sound of your audio equipment
where it all begins: the mains power supply. The power from the mains socket is being
‘abused’ even before it enters your audio equipment. The energy company uses the mains
supply to control government property equipment, like streetlights. Also other equipment is
communicating with each other by use of the mains power supply. But there is more: the
past 25 years switching power supplies have made their way into computers, TV’s and
other home appliances. These devices pollute the mains supply with nasty pulses. This
“Trojan Horse” comes into your equipment without you being aware of it. The pollution has
to be taken out of the mains power supply before it reaches your (analogue) audio
equipment. The Essential Audio Tools cables, distribution boxes, filters and phase indicator
make any audio set perform better.
Essential Audio Tools invests lots of time and effort to make products as good as they can
be. They are all made with use of precision CNC machining. Beautifully shaped,
well-designed and manufactured from top-quality material by experts. Experience the
quality of our products and listen to the results, then you know what we mean.
We wish you lots of pleasure!
Introduction

The Mains Multiplier is not a regular multiple socket but more a work of art made on a CNC
machine that shapes this form out of one piece synthetic material. Yes… synthetic! The
results speak for themselves, optical as well as electrical.
The type of outputs is chosen because of the high contact pressure, which is obvious when
putting in or pulling out an electric plug. More contact pressure and an optimal contact
surface do create a low resistance value. This is very important for good power distribution.
The wiring for phase, neutral and earth is connected by a star principle. Every output has its
own wiring towards the feed cable. Peaks in the current or interference signals that appear
on contacts of one socket will now have less effect on the other sockets.
A ‘Pulse Protector’ is integrated behind the IEC input connector. This prevents peaks and
pulses reaching your audio equipment. Our Pulse Protector is also available as a separate
tool, please check our website.
Where to use
Wherever you need to connect multiple loads to the mains, the Mains Multiplier is the best
choice. Of course you will have to use high performance power cords, else the Mains
Multiplier will not perform at its best. It's a combination of factors, only if you use the Mains
Multiplier in combination with high performance power cords -like our Current Conductor-
you will achieve the maximum results for your audio system.
Of course it is possible to use the Mains Multiplier as an ordinary multiple socket without high
performance power supply cables. Our advice is to buy better power cords, the results will
be rewarding.
What to expect
An improvement in dynamics, a much better sound image and a lower hum level. The
sound character of your audio system remains, fortunately!
By using the Mains Multiplier with integrated Pulse Protector your equipment has less trouble
with electrical failures induced by distortion on your network and it is better protected
against damage through lightning impacts nearby. A guarantee that lightning impacts will
not damage your equipment can not be given because the energy-content of lightning is
too high.

For your protection and safe operation of the unit, please read the following:
Avoid water and other liquids
To avoid risk of fire and electrical shock: do not expose this device to moisture. Use indoors
and in dry locations only. Do not expose to dripping and/or splashing. Do not place objects
filled with liquids -such as vases- on or near the device. Do not operate the unit if any liquid
is spilled on or into the unit; return it to your dealer for servicing.
Don't open the device
To avoid risk of electrical shock: do not open the device. There are no user serviceable
parts inside. Repairs have to be performed by qualified personnel only.
Unplug before cleaning
Always disconnect the unit before cleaning. Only clean the unit with a dry cloth or duster.
Do not use any cleaning solutions, sprays or water.
Connect to mains ground
For safety reasons and to protect connected equipment, this product MUST be connected
to mains with a three conductor power cord which includes a working ground conductor.
The power cord MUST be plugged into a grounded AC power outlet (3-pin). Do not use a
3-to-2-pin adapter to bypass the grounding pin. Failing to plug this product into a
grounded outlet through a ground conductor including mains cord may result in personal
injury or damage to your equipment. Call a licensed electrician if you are unsure if your AC
outlets are properly grounded.
Do not overload individual outputs
Do not connect loads which draw more current than the maximum rating for each
individual outlet. Possible damages due to exceeding these maximum ratings will void
warranty. The MAXIMUM CURRENT rating for each outlet may differ, please look at the
Specifications further on in this manual for maximum loads.
Do not exceed maximum total load
The total current drawn from all outlets together may not exceed 16 Amps. At 230 Volts
mains supply this is equivalent to 3680W.
Check your supply voltage
This device is designed for 220-240V~ @ 50/60 Hz mains supply. Connecting to a different
voltage may damage the device and warranty will be void.
Avoid condensation
If the device is moved from a cold to a warmer area, allow the product to warm up to
room temperature before connecting it to the mains supply. This is to avoid condensation
inside the device.
Connect power cords safely
Power cords should be routed in such a way that they are not likely to be walked on or
pinched by items. Do not route power cords near heat sources. To disconnect the power
cord, pull it out by the plug (wall outlet side first). Do not pull the cable itself, doing so may
result in damage which can lead to fire or electric shock.

Connections
Integrating your new Mains Multiplier 5 / 7 / 8 is as easy as can be.
Just connect the Mains Multiplier 5 or Mains Multiplier 7 to your wall socket. Use a phase
indicator (like our Sound Saver) to test which contact of your mains supply wall socket is
phase. You found it when the LED indicator lights. Essential Audio Tools power cords
(Current Conductors) are marked with a red dot to indicate the phase. Now you know
how to plug the power cord in; red dot mark at the phase of the mains supply wall socket.
For the Mains Multiplier 8 it is not necessary to check the phase of the mains wall socket
because it has a phase indicator integrated which shows the following indications:
no power
power on power on
power on
false phase
phase okno earth connected
If you get a false phase indication by a red light, you should reverse the power cable plug
in the wall socket. You will notice that both indicators will light green which means that the
power is on and phase is ok.
For countries with an earth pin in the middle of the mains supply wall socket (France,
Belgium) it is not possible to reverse the power cord plug in the wall socket. You should ask
a technician to reverse the neutral and phase in your wall socket, NOT in your power cord.
Don’t do this yourself, the mains voltage is dangerous!

The HF filtered outputs are meant for digital and analog sources like cd-players, tuners,
DAC’s and turntables. Power amplifiers should be connected to the direct outputs.
Your Mains Multiplier must be connected to an earthed mains supply wall socket, however
if you do not have earth the Mains Multiplier will still function. 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.
Tips
For maximum noise reduction, it is best to keep power cords and audio cables separated
by some distance from each other, also avoid routing cables in parallel.
Use high-quality power cords (our Current Conductors for example) to connect your
equipment. The screenings will prevent stray-fields reaching 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 device will possibly cause interference and/or hum.

There are no serviceable parts inside. Do not open your Mains Multiplier!
Please check the following before requesting service:
1 – Check the wall socket by plugging in a light or load to check if the power is present.
2 – Check if the power cord from the wall socket to the Mains Multiplier is functioning and
make sure the power cord is plugged deep enough into the Mains Multiplier’s input.
3 – Check your equipment and the power cord by connecting them directly to a wall
socket to test if they work without the Mains Multiplier in between.
Please contact your local dealer if all of the above is tested and working, but the unit is still
not functioning.
