PAC-SNI1 PAC RCA Ground Loop Noise Isolator

The PAC SNI-1 RCA Ground Loop Noise Isolator is a plug-and-play audio accessory engineered to eliminate alternator whine, hum, and buzz caused by ground loops in car audio, marine, and home entertainment systems. By physically breaking the electrical ground path between your audio source and amplifier, it stops unwanted DC currents while allowing the audio signal to pass cleanly through.
