  • iFi Audio iDefender+

    Is your audio still taking a beating from 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. 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.

    Beat the buzz.

    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.

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

    SuperSpeed

    ‘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.
