Mains Multiplier 8+

- 'Star-wired' phase, neutral and earth for best performance

- Group I with four high current contacts

- Group II with four individual filtered contacts for medium current loads or digital sources

- Unique Ground-Bridge selector for external 'audio' earth connection

- Clever indicator for proper mains connection

- Protects all eight contacts by the Pulse Protector inside

- IEC C20 input connector gives the freedom to use preferred power cord

Working principle

The Mains Multiplier 8+ is not a regular multiple socket, more a work of art made on a CNC machine that shapes this form out of one piece of synthetic material. Yes… synthetic! The results speak for themselves, optical as well as electrical.

The type of the eight sockets is chosen because of the high contact pressure, which is obvious when putting in or pulling out a power plug. More contact pressure and an optimal contact surface do create a low resistance value which is very important for a good power distribution. 

The wiring from phase, neutral and earth is connected by a star principle. Every output has its own wiring towards the input connector. Peaks in the current or interference signals that appear on the earth contacts of one socket will now have less effect on the other sockets.

Group II filtering

Group II contacts each have their own high frequency Common Mode filter, so in total four filters can be found in this group. Connected loads do not "see" each other and disturbances from the mains supply or disturbances induced by one of the loads will not have a negative effect on the overall audio performance.

The Mains Multiplier 8+ is supplied without a power cord. It will work with every power cord with an IEC plug C19 which is standard for high current equipment.

However to make you benefit from all the Mains Multiplier 8+ qualities you need to connect to the mains supply with a Current Conductor HC

Where to use?

Wherever you need to connect multiple loads to the mains, a Mains Multiplier is a wise choice. Of course you will have to use high performance power cords, else a Mains Multiplier will not perform at its best. It's a combination of factors, only if you use a Mains Multiplier in combination with high performance power cords you will have the maximum results for your audio system.

Of course it is possible to use a Mains Multiplier as an ordinary multiple socket without high performance power cords, but this will not give you optimal results. Our advice is to upgrade to our power cords, the result will be rewarding.

Unique Ground-Bridge selector

The Mains Multiplier 8+ is equipped with our unique Ground-Bridge selector. It offers you the option to connect to an external earth instead the earth from the wall socket which is shared with all other devices in your house.  In most cases this external earth is a special copper electrode placed deep into the ground, outside your house, preferably it is used for your audio only.

With the Ground-Bridge placed between the black and the green connector you have your Mains Multiplier 8+ connected to the wall socket earth. With the Ground-Bridge placed between both black connectors you can feed the external earth to the green connector on your Mains Multiplier 8+.

Clever phase indicator

The Mains Multiplier 8+ has a very clever way to indicate that it is connected to the mains supply the right way. Two LED's will show you if the Mains Multiplier 8+ has an input voltage, if earth is present and if the mains supply's phase is connected properly.

If the Mains Multiplier 8+ is connected the right way, you will see two green lights. If one light is off or one light is red, something is wrong with your connection. Have a look at the figure for an explanation of the different indications.

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 impact nearby. A guarantee that lightning impacts will not damage your devices can not be given because the energy-content is too high.

Just behind the IEC input connector a Pulse Protector is integrated. This prevents peaks and pulses to reach your equipment. For more information, read about the Pulse Protector elsewhere on this site.
