Say goodbye to buzz and hum!iFi’s iDefender+ is for those battling with noisy audio due to unwanted ground loops in their audio chain. Using multiple plugs within your audio chain means separate earth/ground points, which can lead to a ground loop problem, creating an unwanted chain of noise, buzz and distortion.
iFi’s iDefender+ provides the simple, effective solution you need. 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. The circuitry has also been upgraded; low-ESR tantalum capacitors have been added for improved input and output filtering.

Using a USB DAC?
clean powerIf you're 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, then 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 also be significantly improved.
Amazing Features
‘SuperSpeed’ USB 3.0‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for higher audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
5v/2.5aInject 5 volts of clean power using the ‘separate’ USB-C port. This disconnects the USB power from the PC and replaces it with clean external power. For ultra-low noise, use the 5-volt iPower Elite or iPOWER X. To ‘break’ the earth/ground on USB-powered DACs, adding a separate 5 volt supply is necessary. This isn't required for DACs with an internally-powered USB section.
iso earthKills USB power noise by ‘breaking’ the earth/ground loops in the correct way. It significantly reduces the system noise floor and makes for better dynamic contrast, warmth and resolution.
