Beat the Buzz
Is your audio plagued by hum and buzz? Using multiple plugs within your audio chain means separate, multiple ground points that can cause a ground loop problem. This creates an unwanted chain of noise, buzz, and distortion which causes a significant part of the music signal to be lost. Struggle with hum and buzz no more. iFi’s iDefender+ provides the simple, effective solution you need.
Break the Loop
When plugged into the source devices USB jack, the iDefender+ detects whether there is a ground loop problem. If it finds a problem, it breaks the ground loop by intelligently disconnecting the computers ground and eradicating audible ground-loop hum. It also lowers the system noise floor, improving resolution and dynamic contrast.
Using a USB DAC?
If you are using the iDefender+ with a DAC that relies on USB power from a computer rather than AC power or a built-in battery, weve got good news. The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C jack on its side, it blocks power from the computer and instead feeds the DAC with clean power from the external supply. And 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
The iDefender+ is the latest and greatest version of iFi Audio’s Defender. With the new version, iFi upgraded the circuitry. Low-ESR tantalum capacitors have been added for improved input and output filtering. As a result, filtering capacitance has been increased tenfold.
IsoEarth System
The iDefender+’s IsoEarth circuitry kills 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.
Inject Clean 5V Circuitry
Inject Clean 5V Circuitry inject five volts of clean power clean via the separate micro port. This disconnects the USB power from the PC and replaces it with clean external power. For ultra-low noise, use iFi's 5-volt iPower X. Adding the separate 5 volts to the unit is necessary to break the earth/ground on USB-powered DACs. This is not required for DACs with an internally-powered USB section.
SuperSpeed USB3.0
SuperSpeed USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
