Sparkfun Ground Loop Isolator

The Ground Loop Isolator effectively eliminates ground loop noise in audio systems. Compact and versatile, it connects between your audio board and the line-in of amplifiers or other equipment. Utilizing magnetic coupling, it transfers audio signals while blocking unwanted DC power supply ground currents.

Perfect for use in home studios, live sound setups, or any audio environment plagued by ground loop issues, this isolator ensures clean and clear sound transmission. Simply plug it in, and enjoy interference-free audio without the hassle of complicated installations or additional equipment.

One of the key benefits of this device is its bi-directional nature, allowing either side to function as the input or output. This flexibility makes it a valuable addition to any audio toolkit, accommodating a wide range of configurations and setups.

For optimal performance, connect the isolator to impedance line-in devices such as amplifiers, mixers, or effects pedals. While it excels in these applications, using it with low impedance devices like headphones or speakers may result in some signal loss, particularly at lower frequencies.
