Beat The Buzz Is your audio still plagued by hum and buzz? Using multiple plugs within your audio chain means separate earth/ground points. These multiple earth or ground points cause a ground loop problem. This creates an unwanted chain of noise, buzz and distortion. Struggle no more. the iFi Audio iDefender+ provides the simple, effective solution you need. Break The Loop When plugged into the source device’s USB socket, the iDefender+ from iFi Audio detects whether there is a ground loop problem. It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth and, as well as eradicating audible ground-loop hum, it lowers the system noise floor, improving resolution and dynamic contrast. Using a USB DAC? Are you using the iDefender+ with a DAC that relies on USB power from a computer rather than power from the mains or a built-in battery? Good news. The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C socket on its side, it blocks power from the computer and instead feeds the DAC with ‘clean’ power from the external supply. If a high-quality, low-noise power adapter such as iFi’s iPower X is used, the performance of the USB DAC will be significantly improved. New and Improved iFi Audio has upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold. The iDefender+ now comes in 3 versions and includes the newer USB-C connector. USB-A to USB-A USB-C to USB-A USB-C to USB-C Beat the buzz with the iDefender+.
