IFI AUDIO iDefender + Type A > Type A

Product description

Audio setups will suffer from an annoying hiss, buzz, or hum when more than one component in the system carries a ground, which creates ground loop feedback. Using multiple plugs with separate earth points, usually identified by three pin connectors like your desktop power cord or laptop charger and the power cable from your studio monitors, or speakers, introduces multiple earths and creates an unwanted chain of noise, buzz and distortion. You need a way to break these multiple grounds in the audio chain to correct your system, and this is how the iDefender+ will help. It plugs directly into your computer or car USB port, auto-detects if there is more than one earth, and intelligently and safely disconnects the earth to remove the background noise for cleaner sound. If you’re unsure about a potential ground issue, you can try placing your hand on the music device (PC, CD player, etc) and listen if the hum stays the same or disappears. If the humming is still present or gets worse, the i Defender + could be the perfect solution. If the noise disappears, it means your system is missing a ground and must have one added. The iDefender also works with USB powered DACs (digital to analog converter) and USB hubs by adding the iFi iPower 5V to inject clean power into the USB C port located on the side of the device. Other 5V power supplies can be used and will benefit from and additional noise filtration from the iDefender+. To make sure a wide range of devices are compatible the iDefender+ is available in 3 connection versions: USB A input to A output, USB C input to C output, USB C input to A output.

Product Description

• iFi was born in 2012 with one goal in mind: to produce ‘ultra-fidelity’ audio products that push the sonic envelope whilst still priced within the mainstream.
• iFi audio is under our parent company, AMR, Abbingdon Music Research, which designs and produces top-end luxurious audio products. AMR saw in 2010 that customer demand for wireless and portable headphones was expanding as the whole audio dynamic was changing. Thus, iFi was launched.
• iFi offers small but prodigious personal audio products thanks to the superior knowledge of AMR’s technology. Today, we are proud of our British (and international) roots. We continue to design and produce over 35 different products. We are headquartered in Southport, UK with distribution including retailers such as B&H and etailz with production overseas.
• We source parts from around the world from manufacturers including AMOS (UK), GE Valves (USA), WIMA (Germany) and TDK (Japan).

iDefender+ A-A

When plugged into the source device’s USB socket, the iDefender+ detects whether there is a ground loop problem, caused by the presence of multiple earths that add noise. It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth; as well as eradicating audible ground-loop hum it lowers the system noise floor, improving resolution and dynamic contrast.
