Pairing a headphone with an impedance of 2.5-8 times higher than the source impedance should yield good results. This recommended ratio is commonly known as the ‘rule of eighths’ and contributes to proper driver control (damping factor).

What is the advantage of a low impedance ground versus a high

WebIn a Low-Resistance Ground System (LRGS), it is difficult to detect a high-impedance ground fault (HIGF) using conventional over-current protections because of its low fault current. In this paper, a novel HIGF detection method based on phase current increment ratio is proposed.
