Nordost Ground Wire

By Nordost



One of the most incessant problems that plague a hifi system is that annoying hum. Noise is triggered when two circuits carrying different amounts of current overlap each other, or when a loop is created by stray magnetic fields generated by transformers in connected equipment. This problem is only magnified when your system is spread between several connected wall outlets throughout your listening room, as many are. The only solution to this problem: separate the circuits so that no overlaps occur by providing a designated ground. 

QLINE Ground Wire is the most effective method to achieve a solid secondary ground for your hifi audio system. Utilizing Nordost’s patented Micro Mono-Filament technology, combined with extruded FEP insulation, QRT Ground Wire is the missing link needed to complete the circuit —connecting the QBASE ground post to a designated, external ground rod or grounding box through its uniquely low resistance path. Proper grounding will transform your system, offering enhancements in 3D imaging as well as lowering the noise floor.

Nordost’s QRT Ground Wire is available in multiple lengths with air-tight, waterproof terminations in order to accommodate your specific needs: grounding from device to device or running your QRT Ground Wire from your QBASE distribution block to an external ground rod. It is important to recognize, that while installing a designated ground for your hifi system is the most efficient and direct approach to eliminate ground loops and AC hum, there are some states and countries that prohibit the use of a second ground. Please consult a local electrician to ensure that the improvements you make on your sound system remain to code.
