Plug the iFi iDefender3.0 Ground Loop Eliminator Right into the USB Audio Source and Eliminate Hum, Reduce the Noise Floor, and Hear Better Clarity: Creates a Clean External Power Supply
A single-purpose accessory that stops ground-loop noise and hum, reduces the noise floor, and disconnects the USB power from your computer by replacing it with a clean external power supply, the iFi iDefender3.0 Ground Loop Eliminator plugs right into the source (such as a PC USB port) and allows data to pass freely. Designed for home and mobile use on DACs with an internally powered USB line, iDefender3.0 literally breaks the ground connection to eliminate earth loops, providing both a comprehensive and electronically proper solution other similar products lack. The result: Significantly improved dynamic contrast, warmth, resolution, and texture. For DACs that require a USB power supply, the iFi iPower 5V can be used to supply iDefender3.0 and attain optimal performance.
