the system from noise and distortion caused by ground wire or ground loop, reduce interference between ground loops, and reduce system noise ^^ Can be used when there are many USB devices terminated by the computer, which can reduce the mutual crosstalk between devices ^^ Optimized between power and ground loops, with good EMI/RFI blocking and power performance ^^ Improve the stability of USB work, and at the same time have a certain power for the device ^^ For devices with high USB power supply requirements, such as sound cards, connect the USB 3.0 isolator to reduce ground loop noise and make the music output by the sound card clearer ^^ ^^ ^^ ^^ ^^
