Ground Loop Isolator

This ground loop isolator is a simple inline fix for unwanted hum and noise caused by ground loops in audio setups. Place it between your audio board and the line-in of an amplifier or other compatible audio equipment.

The unit is bi-directional, so either side can be used as the input or output. Internally, it uses magnetic coupling to pass the audio signal while blocking DC power supply ground currents.

For best results, connect the output to impedance line-in devices such as amplifiers, mixers and effects pedals. Low impedance loads such as headphones or speakers can cause signal loss, especially at lower frequencies.
