Halloween Special Ifi Audio Idefender+ External Usb Audio Ground Loop Eliminator (type A To Type A) Set [S6wTcEAn]

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 a simple, effective solution you need.

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.

• USB-A to USB-A
• USB-C to USB-A
• USB-C to USB-C

Beat the buzz with the iDefender+.

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 5 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 our 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’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backward compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
