جهاز iFi audio iDefender+ للحماية ضد ضجيج الحلقات الأرضية وضجيج طاقة اليو اس بي من أي أف أي أوديو

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.

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.

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.

The iDefender+ now comes in 3 versions and includes the newer USB-C connector.
