Eliminate ground loop hum and AC noise with the Nordost Q Line Ground Wire, engineered to connect your QBASE ground post to an external ground rod or grounding box. Built with patented Micro Mono-Filament technology and FEP insulation, this low-resistance conductor features a 10 AWG 99.9999% OFC 231-strand design for optimal signal purity. Standard termination includes a large spade connector (8.5mm) to crimped ferrule (18mm x 3.8mm), with alternative options available. Fully manufactured and terminated in the USA with airtight, waterproof construction, it's available in multiple lengths to suit your installation. Proper grounding delivers enhanced 3D imaging and a dramatically lowered noise floor. Note: Consult a local electrician to verify compliance with local electrical codes before installation.
