Ground loops are one of the most common causes of hum and buzz in sound reinforcement systems and other
audio products. A ground loop usually occurs if the separate pieces of equipment are plugged into different AC
circuits. Also, if the audio wiring is placed too close to the power cords, hums or buzzes can bleed into the system. Still, improperly maintained power and audio cables are yet another cause of bothersome noise. In order to help minimize stray hums and buzzes, here are some helpful hints.
1.Keep all electronics connected to the sound system on the same electrical circuit.
2.Keep audio signal cables away from the AC power cords.
3.Use balanced cables when applicable.
4.Always plug the SRM 6302 / 8302 into a grounded AC electrical outlet.
5.Be sure to use properly maintained cords and cables with the SRM 6302 / 8302.
