Why earthing is crucial

Electronic devices in the home can generate unwanted high-frequency interference and impair sound quality. However, disruptive hum is often caused by faulty or missing earthing of the hi-fi chain. Terra brings together all necessary earths at one central point and thus prevents hum loops.

Well-conceived design

The star-shaped end-point design reliably prevents hum loops. The housing is filled with special sand that specifically dampens vibrations and electromagnetic interference – for an unadulterated sound experience.

Safe via protective earth

A plug that is connected exclusively to the protective earth ensures that earthing takes place via the socket without establishing a direct connection to the mains supply. This offers additional safety and guarantees the combined discharge of all potentials.

Flexible connections

The rear of the Terra earthing box offers three connections for direct earthing and three further connections with potential difference. This allows the earthing to be individually adapted to different requirements. Three high-quality earthing cables are included in the scope of delivery.
