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
