Product details
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.
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+.
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 backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
