QLINE GROUND WIRE
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.
The effectiveness of electrical grounding in a hifi audio system can mean the difference between enjoying your music and falling in love with it. Contamination from RMI/EFI, electrical surges and switch-mode hash from home appliances, lighting, and wireless frequencies have a noticeably damaging effect on the performance of any sound system, making music less engaging and in bad cases, tiring to listen to. The following download will help you better understand why grounding is needed, what improvements can be heard in a properly grounded system, and what artificial grounding solutions can offer you.
