In audio and video systems, establishing reliable signal grounds is critical, as they create a “zero reference” point for both digital and analog devices. Music is comprised from varying waveforms with positive and negative amplitudes oscillating around a zero value. Having a true zero reference point for your system is critical for fidelity and clarity. In digital systems, it is important to recognize that true square waves do not occur in nature or in laboratory settings; rather, they are complex constructs, composed of multiple sine waves. The higher the sample rate and bit depth, the more crucial the zero-value reference point becomes.
Power conditioners are often deemed essential for optimizing audio and video systems, particularly when external noise affects performance. However, their necessity is primarily acknowledged in contexts where noise outside the 50-70 Hz AC power frequency range is a concern. It is crucial to manage this noise before it can adversely impact equipment performance. While power conditioners are effective in filtering out certain types of noise, they do not mitigate AC noise within the utility AC power frequency. In contrast, active power regeneration systems can isolate equipment from utility AC mains. It’s important to note, though, that active solutions utilize some of the input power, which can inadvertently diminish power delivery to your equipment, potentially elevating the noise floor and diminishing the effectiveness against transient disturbances.
Effective chassis grounding significantly reduces electromagnetic interference (EMI) that degrades equipment and cabling. Cables and PCB traces act as unintended antennas—both radiating and receiving. Controlling emissions and susceptibility is essential in high-performance systems. Unfortunately, in many products, the power/earth and chassis grounds are bonded at the power entry and at chassis‑mounted connectors; this layout can couple power‑supply and chassis noise into signal paths, where it reaches speakers or video displays. EnKlein applies technology and decades of experience to engineer and construct power distribution components with integrated chassis‑grounding architectures, substantially nullifying these noise pathways.
EnKlein develops advanced analog and digital signal‑transmission and sensing solutions for commercial and government clients. Our founder, David, holds 30+ patents in applied AI, signal processing, and systems engineering. FAA closed‑air booths operate in inherently high‑power EMI environments. The U.S. Government deployed a highly effective, fully transparent glass solution for this setting, with David serving as the science lead. These results reflect our commitment to delivering innovative solutions for both communications and non‑communications systems. Elevate your audio and video performance with our expertise and cutting‑edge technologies.
