It is designed to perform well in mainstream and mid-fi systems, offering a straightforward introduction to Entreq's approach to signal grounding without requiring a significant outlay.\u003c\/p\u003e\n\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003cp\u003eAll Eartha ground cables are terminated at one end with a hook connector that connects directly to your Entreq ground box. The other end is specified and hardwired at the time of ordering, which Entreq state gives the best possible performance. If you prefer flexibility, you can specify a 3.5mm male connector (Level 1 or 2) in place of the hardwired termination, allowing use with Entreq's range of Click Adaptors.\u003c\/p\u003e\n\n\u003cp\u003eAdditional lengths are available in 550mm increments beyond the standard 1,650mm.\u003c\/p\u003e\n\n\u003ch2\u003eMaterials\u003c\/h2\u003e\n\u003cp\u003eThe Eartha Copper is built from wood, copper, and cotton — materials chosen as part of Entreq's broader approach to grounding and signal drainage.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Ground Boxes\u003c\/h2\u003e\n\u003cp\u003eThe Eartha Copper works best with the following Entreq ground boxes: Silver Minimus Tungsten, Tellus 3 Tungsten Performance, and Tungsten Performance models.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\ntable\u0026gt;\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e1,650mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterials\u003c\/td\u003e\n\u003ctd\u003eWood, Copper, Cotton\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination (ground box end)\u003c\/td\u003e\n\u003ctd\u003eHook connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination (component end)\u003c\/td\u003e\n\u003ctd\u003eHardwired as standard; 3.5mm male available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdditional lengths\u003c\/td\u003e\n\u003ctd\u003eAvailable in 550mm increments\u003c\/td\u003e\n\u003c\/tr\u003e\n\/table\u0026gt;\n\n\u003ch2\u003eWho Is It For?\u003c\/h2\u003e\n\u003cp\u003eThe Eartha Copper is the sensible starting point if you are new to Entreq's grounding system and want to understand what it does before committing further. It suits mainstream systems where the Silver Minimus Tungsten or Tellus 3 Tungsten is already in place, or is being considered alongside it. If your system sits at a higher level, Entreq's Eartha Silver or Eartha Apollo cables would be the more appropriate choice.\u003c\/p\u003e\n\n\u003ch2\u003eBuying from Martins Hi-Fi\u003c\/h2\u003e\n\u003cp\u003eMartins Hi-Fi has been in Norwich since 1968.
