iFi iDefender+ USB Ground Loop Isolator (USB-A to USB-A)

Put an End to Annoying Buzz

Individuals who still encounter the annoyance of hum and buzz in their audio system can now find solace in the iDefender+. When multiple plugs are used within the audio chain, distinct earth/ground points are established, often leading to ground loop problems. These ground loops introduce unwanted noise, buzz, and distortion into the audio. Fortunately, the iDefender+ provides a straightforward and highly effective remedy.

Breaking the Loop

Upon plugging into the USB socket of the source device, the iDefender+ is equipped to detect the presence of ground loop issues. It intelligently disconnects the computer's earth, effectively eliminating the audible ground-loop hum. Moreover, this action results in a lower noise floor within the system, ultimately enhancing audio resolution and dynamic contrast.

A Game Changer for USB DAC Users

For those using the iDefender+ in conjunction with a USB DAC that relies on power from the computer rather than mains power or an internal battery, there's good news. This device offers an additional benefit. By connecting an external power supply to the USB-C socket on the side, it prevents power from the computer and instead supplies the DAC with clean power from the external source. Users can experience a significant improvement in the performance of their USB DAC, especially when using a high-quality, low-noise power adapter like iFi's iPower X.

A New and Improved Solution

The iDefender+ has undergone significant enhancements. Circuitry upgrades include the addition of low-ESR tantalum capacitors for improved input and output filtering, with filtering capacitance increased tenfold. Additionally, the iDefender+ is now available in three versions and features the newer USB-C connector.

Say Farewell to Buzz with iDefender+.

Embracing the Future with 'SuperSpeed' USB 3.0 By embracing the 'SuperSpeed' USB 3.0, these devices offer an extensive wiring specification, allowing for increased audio transfer rates while maintaining backward compatibility. Gold-plated connectors ensure optimal signal transfer.

Injecting Clean Power

With a separate USB-C port, users can supply their systems with 5 volts of pristine power. This action isolates the USB power from the PC, replacing it with clean external power. To minimize noise, consider the use of a 5-volt power adapter such as iFi's iPower Elite or iPOWER X.

Eliminating USB Power Noise Effectively

The iDefender+ excels at eliminating USB power noise by correctly breaking earth/ground loops. This results in a substantial reduction in the system's noise floor, offering improved dynamic contrast, warmth, and audio resolution. iDefender+ delivers cleaner, more pristine sound quality to users.
