FAQ:
Q: What type of noise can this device eliminate?
A: It eliminates humming noise caused by ground loops when the audio source and devices like mixers or home audio systems share the same power supply, resulting in a clearer sound output.

Q: What is ground isolation?
A: Ground isolation is a technique that connects the ground terminals of multiple devices to a single grounding point. This reduces high-frequency noise (such as ground loop noise) on the ground line and improves overall system performance.

Q: Can it eliminate noise that's not caused by shared grounding and power?
A: This product can only eliminate noise and electrical hum caused by shared ground and power sources. It cannot eliminate noise caused by other factors, so users must first identify the source of the noise.

Q: How can I tell if the noise is caused by a ground loop?
A: Methods include:
1. Computer, amplifier, speaker, CD player: Connect passive headphones directly to the computer and check for noise. Then connect the computer to the amplifier and speakers to test again. If neither test alone produces noise, but noise occurs only when all are connected together, the problem is likely due to ground loop interference.
2. If you hear electrical hum between a mixer and an amplifier, you can install this product between them to eliminate it.
3. If connecting a laptop to a projector and amplifier produces noise, try using the laptop on battery or with a power adapter. If disconnecting the amplifier or the projector makes the noise disappear, a ground loop isolator between the laptop's headphone jack and the amplifier may resolve the issue.
4. If you connect a battery-powered phone or MP3 player (not connected to any power source) to a car's central control AUX input using an audio cable and there is no noise while playing music, then the previous noise was likely caused by a ground loop.
