Attention audiophiles! We are selling an Earthquake Pro GLI-200 ground loop isolator designed to remove annoying hum, noise, and buzz from your audio system. Simply insert this between your amplifier and source component or subwoofer using the RCA inputs and outputs. Has 600 ohm impedance, so no degradation in sound. This little guy really works! Only selling because we no longer use home theater pass-through from our main system. Was getting a hum in the speakers and tried other products, but this little device reduced the hum by 99% to where it was barely detectable. Asking $20. Thanks for looking!
