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. Add the iPower2 5V to help cacnel out all incoming EMI and RFI noise, you’ll never feel powerless against noise and graininess again. The new iPower2 boasts improved components and a thicker gauge of wiring to deliver improved output/input noise suppression.

Plug in, turn on, and chill out.

iPower2 comes with a set of 5 five differently-sized adapters to suit some 73% of DC plugs including a reverse polarity (white plug) for professional audio products that require a centre negative feed.

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.

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 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.

‘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.
