Your AC power lines are contaminated with electrical surges, pulses, and switch-mode hash from home appliances, plug-in chargers, light dimmers, and fluorescent and LED lights. Even the air is polluted by radio frequency interference (RFI) and electromagnetic interference (EMI), levels of which are increasing due to the prevalence of Bluetooth, Wi-Fi, and cellular signals.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"334\" src=\"https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01-1024x334.png\" alt=\"\" class=\"wp-image-5857\" srcset=\"https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01-1024x334.png 1024w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01-300x98.png 300w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01-768x251.png 768w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01-500x163.png 500w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/11\/signal-ground-01.png 1351w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Q: What is signal ground and how can it negatively impact my system?&nbsp;<\/p>\n\n\n\n<p>A:&nbsp;A signal ground is an analog or digital ground that is attached to every signal being transmitted between devices in a system. Since these devices are usually powered separately, it is inevitable that there will be small differences between their potentials, causing small currents to circulate in order to compensate. These currents add to the background noise, obscuring low-level detail in music reproduction.&nbsp;<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Q: What does an &#8220;Artificial Ground&#8221; do?<\/p>\n\n\n\n<p>A: An artificial ground sinks the impedance of a component lower than the house earth ground, so that high-frequency noise on the signal ground will drain away, leaving a clean reference behind.&nbsp;<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Q: What audible improvements can I expect to hear after addressing grounding issues in my system?&nbsp;<\/p>\n\n\n\n<p>A:&nbsp;&nbsp;There are several improvements you can count on by addressing the grounding issues in your system. The image separation will be greatly improved, exposing nuances in dynamics and accent markings that would otherwise have been missed. You\u2019ll also experience a tighter, deeper, and more authoritative bass. However, the most noticeable change will be a dramatic drop in your noise floor which will provide a quieter, \u2018darker\u2019 background, resulting in a wider, more lifelike soundstage.&nbsp;<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"475\" src=\"https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-1024x475.jpg\" alt=\"\" class=\"wp-image-5503\" srcset=\"https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-1024x475.jpg 1024w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-300x139.jpg 300w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-768x356.jpg 768w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-1536x712.jpg 1536w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-2048x949.jpg 2048w, https:\/\/nordost.com\/blog\/wp-content\/uploads\/2020\/05\/QKORE-three-versions_style-1-500x232.jpg 500w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Q: What is Nordost&#8217;s solution to grounding problems?&nbsp;<\/p>\n\n\n\n<p>A: Nordost&#8217;s grounding solutions are&nbsp;<a href=\"https:\/\/www.nordost.com\/qrt\/qkore-ground-unit.php\">QKORE Ground Units<\/a>.&nbsp;QKORE units are parallel grounding devices which provide an artificial, \u201cclean\u201d earth for hifi audio systems using both an electrical and mechanical approach.
