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 devices USB socket, the iDefender+ from iFi Audio detects whether there is a ground loop problem.

It breaks the ground loop by intelligently disconnecting the computers 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 iFis 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
