Olympus Hero GroundBox

Using our unique Athena construction and technology to house five Olympus Infinity T ground boxes as well as incorporating a Cleanus, the Entreq Olympus Hero is exceptionally well suited to high-current applications including negative speaker grounding and power cables.

The Olympus Hero – our pride, our baby, and our statement!

This ground box is built with new materials, new technology, and a new construction that makes it a Swiss army knife of sorts. The Hero contains 5 Olympus Infinity T boxes and 1 Cleanus, providing a level of performance and an almost limitless set of options.

You have the option to use the boxes separately, connecting an Eartha cable to each cell. Or you can bridge connect 2, 3, or 4 cells together with our T-Links for even greater impact. The Hero also contains a Cleanus in the vibration-damped box, meeting all your demands.

When connected to a wall socket, the Hero provides an effect equal to using a Cleanus, ensuring a clean signal path. The five Olympus Infinity T boxes enclosed in the Hero are housed in a vibration-damped Oak box made of the same three-layer material used for the Athena rack and Magma feet, ensuring stability and durability.

Linking cells
Included with the Olympus Hero are four T-Link cables which are used to connect cells within the unit together via the binding posts. This allows you to create grouped cells that can handle much larger components than the individual cells can accommodate. Using all four T-Link cables it is possible to turn the Olympus Hero into one single cell with the ability to ground a single component of 250kg.

Olympus Hero is capable of grounding/draining up to 20 units with a total weight of between 200-250kg. You can connect even more units, but be mindful not to overload the box as you will hear it when you reach its limit. This ground box works well with all kinds of electronics weighing between 8-50kg.

This ground box also works well for grounding all types of power splits and for negative speaker grounding on all amps.

The above guidelines are not set in stone. You will always get an impact when you connect a ground box, but for the best performance, it is important to match the weight of the ground box with the units you connect to.

For the highest quality in all applications, we recommend using Olympus Hero in combination with Eartha Olympus cables. However, you will find that the Eartha Sudoku, Eartha Revelation and Eartha Apollo cables will also provide excellent performance at a lower price point. 

Please note that grounding the negative speaker post on amplifiers can have a significant impact on your sound quality.
