iFi Audio iDefender+

Product Overview

Tired of doing battle with buzz, hum and hiss?

• iFi’s iDefender+ is for those battling with noisy audio due to unwanted ground loops in their audio chain.

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. iFi’s iDefender+ provides the simple, effective solution you need.

Break the loop

• When plugged into the source device’s USB socket, the iDefender+ 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

We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering.  Filtering capacitance has been increased 10-fold.
