iFi Audio GND Defender

The optimum configuration for each system is one ground/earth for the entire system. If a system has multiple grounds, unwanted ground loops are often created. These systems will then have an annoying low frequency hum (emitted by the loudspeakers).

Current solutions compromise either (i) both safety and EMI shielding (e.g., the cheater plug), or (ii) EMI shielding. And most are single country (US) uses only.

The GND Defender in the right way, intelligently detects a ground loop and will cut the ground for that component.

AI ground detection

With a GND Defender on the IEC power input, it will intelligently detect and eliminate the ground loop in the component.

Behind this, the GND Defender:

  • Intelligently breaks DC ground loops to eliminate ground loop hum.
  • EMI shielding is maintained.
  • Equipment safety is not affected (it is not a ground lift - so it keeps equipment safety grounded).

If there are several ground loops, more than one GND Defender may be necessary.

The GND Defender is smarter than the average grounding device. By far.

Armored construction.

The GND Defender is not only state-of-the-art in terms of technology, but also in terms of safety:

  • High performance passivated glass semiconductor.
  • High dielectric strength of 1500VRMS with UL certification.
  • X7R capacitor.
  • High temperature stability.
  • IEC flame resistant socket/connector/chassis.
  • UL94-V0 flame retardant polymers.

Remember that the best practice is to always maintain at least one direct power cable connection.

220A overload capacity. With a maximum rating >10A, 7A DC rating, handles all voltages worldwide from 90-240V.

Intelligently blocks DC mains voltages to eliminate transformer hum. Equipment safety is not affected.

EMI shielding is maintained.

  • AI ground detection Each unit will automatically disconnect the ground from that device.
  • Safety grounding Automatic re-establishment of the ground connection to pass current if a fault is detected.
  • Rated voltage 90 - 240 volts.
  • Overload capacity 220A.
  • Continuous current rating 10A (1100W - 2400W).
  • Universal IEC hospital grade connectors.
  • Dimensions 68 x 37 x 32 mm / 2.7' x 1.5' x 1.3'.
  • Weight 61g / 2.2oz.
