The CAD GC3.1 Ground Control is a passive high-frequency noise reduction system designed to improve audio system performance by converting high-frequency energy into heat. It works by connecting to audio component outputs or Earth ground connections, requiring specialized, low-impedance cables to effectively absorb noise from approximately 700kHz up to over 10GHz. The GC3.1 is a more powerful version for the main power earth and chassis, offering substantial noise reduction.
