Impedance Tolerant EMI/RFI Filtration
- Author: Andy Benton
A/V gear is more sensitive and complex than it has ever been, and signal-to-noise ratios are at levels once not thought possible. However, electrical disturbances and interference on the powerline continue to be a part of life. Preventing even the smallest clicks, pops and buzzes from getting into an audio chain is, therefore, more critical than at any time in the past. Video systems are not immune to noise on the powerline. An unexpected, brief disruption in the video is likely to be due to a powerline transient. Once inside a piece of equipment, EMI/RFI can sneak its way onto any wiring or into any circuitry. It is vital to stop electrical noise from getting inside equipment enclosures. Almost all A/V equipment now has a microprocessor or a DSP embedded inside it. Anywhere there is a memory chip or a digital
device running code there is a risk of memory loss, a crash, a hang-up or a re-boot. Many of these unexpected occurrences are caused by powerline disturbances: transients or noise.
Only the very best power conditioner with an EMI/RFI filter designed to perform under real-world conditions can prevent these kinds of problems from occurring. SurgeX products include proprietary Series Mode Surge Elimination technology and Impedance Tolerant EMI/RFI filter – a combination that was designed to work seamlessly together to provide the cleanest AC power possible.
