Tellus

About the Tellus

The Entreq Tellus is a passive ground box designed to improve HiFi system performance by draining high-frequency noise and interference away from your components into a dedicated grounding enclosure. It is part of Entreq's multi-cell ground box range and is intended to be connected to unused terminals on your equipment (such as RCA, XLR, USB, or speaker negative posts) using Entreq's Eartha grounding cables. By providing a separate, low-impedance reference point for signal and chassis grounds, the Tellus lowers the perceived noise floor, which can subjectively enhance detail, spatial definition, and overall clarity. Earlier Tellus models use three ground terminals and are constructed with a mineral-loaded wooden chassis, while later successors like the Tellus II Infinity and Tellus 3 Tungsten refine the same basic concept with updated internal cells and materials. The original Tellus itself is a single-chassis ground box aimed at serving an entire system rather than just one component.
