Reconnect devices and verify that the ground loop hum has been removed while confirming correct signal level and polarity. If uncertain about wiring, consult device manuals or a qualified technician.

Recommendations

Use the Neutrik NTE1 where audible hum or ground loop interference is present; install at the most convenient accessible point in the signal chain, preferably close to the noisy or ground-referenced device. Avoid placing the unit where it may be exposed to moisture or mechanical strain on the wires.
