One of the most incessant problems that can 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.
While the easiest way to provide a designated ground for your sound system is achieved by using our QKORE grounding system, homeowners with the ability to install an outdoor ground rod will find Nordost’s QLINE Ground Wire an indispensable tool. Utilizing Nordost’s patented Micro Mono-Filament technology, combined with extruded FEP insulation, the QLINE 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 QLINE is available in multiple lengths with airtight, waterproof terminations in order to accommodate your specific needs. 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.
