Shunyata Research GEMINI Model-4

The GEMINI Model-4 combines premium power conditioning with sophisticated ground noise elimination in a compact, dual-function design. Its proprietary NIC™ noise isolation chamber establishes a unified ground reference across your entire system, effectively mitigating AC noise and inter-chassis voltage discrepancies that can introduce ground loop artifacts. This architecture proves particularly advantageous for audiophile headphone setups, where power line and ground plane contamination significantly impacts sonic performance. Network infrastructure—including switches, routers, servers, and computers—demonstrates marked improvement with optimized power delivery and reduced ground noise. Deploying a GEMINI in your network closet yields substantial system-wide performance gains. Despite its modest dimensions, this high-current device handles amplifiers exceeding 200 watts, making it an elegant solution for refined systems seeking comprehensive noise reduction without spatial compromise.

For larger systems with more than 4 components please refer to the Gemini Model-8.
