GROUNDING AND HUMS 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. Keep all electronics connected to the sound system on the same electrical circuit. [. . . ] Avoid spilling any liquids on the operating surface, grilles, volume and tone controls, switches and line cord inputs. ALWAYS unplug the LTB before cleaning it or approaching it with fluids.
