iFi iDefender 3.0+

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.

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.
