Audio Hum Eliminator Ground Loop Noise Isolator Dual Channel Gold Coating

The MICNAUX Audio Hum Eliminator / Audio Signal Isolator is a passive ground loop noise isolator designed to remove 60Hz buzzing and electrical interference from sound systems without affecting bass response. It works by using built-in isolation transformers to break the physical-electrical ground loops between your audio source and output equipment.

Passive Design: The unit operates fully without requiring any external power source or battery.

Gold-Coated Connections: Features a dual-channel design with gold coating to enhance signal transmission and resist corrosion.

Aluminum Shell: Built with a durable aluminum alloy casing that helps shield the inner components from external electromagnetic interference (EMI).

Compatibility Note: This device is not compatible with 48V phantom-powered studio microphones.

How to Use AUDIO SIGNAL ISOLATOR

Connect the output of your audio source (like a laptop, mixer, or instrument) to the Input side of the MICNAUX box.

Connect the Output side of the box to your target device (such as an amplifier, PA system, or active speakers).

If using an XLR variant with a dedicated switch, toggle the Ground Lift button to find the setting that completely kills the background buzz.
