Building on Earthquake’s range of audio problem-solving products, the GLI-200 stands out as the top ground loop isolator available. While standard A/V receiver outputs have an impedance of 600Ω, most current ground loop isolators only provide about 200Ω at best. Using these lower-impedance devices forces your A/V receiver to supply three times more current or accept reduced output levels. The new GLI-200 offers an impedance of 600Ω right from the start, aligning with industry standards. Unlike many alternatives, Earthquake’s GLI-200 is constructed with high-quality components and maintains full low-frequency response without rolling off, thanks to appropriately sized transformers. It effectively eliminates buzz or ground loop noise while preserving audio fidelity.
