Why use our Ground Box’s ?

You will get an improvement in dynamic’s, a lower noise floor and more natural flow in the sound.

For us a clean and effective ground point is one of the most important factor’s in ensuring the best possible sonic platform for any hifi system!
We normally say 220V 50Hz alternative110 V 60Hz. But in our opinion there are a lot more frequence on the power net. These is caused by the way we connect zero and protective ground together in the main central/fuse boxes.Most things these days run on electricity. Current goes in and current goes out of devices and lighting fixtures of every kind. All of these make the current messy. Not least computers with their switched power units, chargers for e.g., mobile telephones, all the halogen and LED lighting, dimmers etc. all cause a great deal of high-frequency noise and stay voltages. This noise always seeks the easiest path to the earth. And since this can be everything from 50-60 Hz to very high-frequency, but weak, currents, it is not always certain that the path of least resistance is via the protective earth. These currents instead can find dishwashers, laundry machines, counter tops with water pipes, your HiFi rack and your stereo set with all the cables and devices as more attractive paths to the earth. Moreover, these stay voltages often generate very large magnetic fields that absolutely have influence on the sound reproduction.
One big problem is that the protective ground many time are overloaded or not constructed for handle this pollutions. It can handle a real “bang” of 110-220Volt and X Watts without any problems, but when it come to this small currents of some Milli V with very high frequence it dont catch them. So instead these will flow arround in the power system searching for a place to ground. And in fact the protective grond can leak back a lot of pollutions to the power net that instead go to f,ex your HiFi system with all the cables and magnetic fields and load up and rest there in their serch for ground.Our ground boxes / Eartha cables are designed to resemble and work like a bit of Mother Earth in concentrated form and offer the simplest and fastest route for this high-frequency noise to reach a earth point. Since such are very high-frequency weak currents, it is not necessary to have a lot of mass; but it is important that the cables are optimized for these high frequency and the groundbox be a purely attractive earth point.The construction and choice of materials in the earth box has a crucial effect on the result. In part, the minerals and metals involved have an effect, but the relationship of proportion and distance between them also affects the result.

When you connect your system to one of our groundboxes you offer this high frequence stay voltages a ground point where they can find peace instead of flowing arround in the system.

Today we have 2 lines ( Mini and Tellus) of groundboxes and 4 levels in each line, start with our entry level and first released models Tellus/Minimus to our latest released Olympus line,so we think you can find a box that fit your demand.
Since the connection cables have a huge impact on the result, we recomend you to choose Eartha cables with care. We have a wide range of Eartha cables from our entry cable Eartha Cupper to our top line Atlantis with all kind of connectors.
Please red more about Earth cables on our cable site..

The Minimus has only a single dedicated ground point. It’s capacity is generally limited to either a couple of dedicated ground cables, to ground your equipment, or for the use with our own signal cables. This can be with our digital, USB, analogue or speaker cables. Please seek the advise of your retailer – distributor on specific
applications & optimisation of our products.
Weight 2 kg W 17cm – H 8cm – D 19cm

Note : Where possible please ground digital & analogue cables to seperate ground points.
