iFi audio iDefender+ iFi iDefender+ USB Power Isolator Ground Loop Noise PC Hifi Audio Music Noise Canceller USB3.0 High Speed Transmission

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. 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. The iDefender+ now comes in 3 versions and includes the newer USB-C connector. USB-A to USB-A USB-C to USB-A USB-C to USB-C Beat the buzz with the iDefender+. ‘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. Inject 5 volts of clean power via 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 our 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 is not required for DACs with an internally-powered USB section. 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.
