Ground loop problems can be corrected and avoided. Only after the system is installed can it be determined Neither the manufacturer nor the installer can usually predict whereĪ loop will occur. Usually ground loops are an after-the-fact type of problem in which theĮnd-user blames the installer, the installer blames the manufacturer, and Use of any of today's standard 120-volt or 230-volt single-phase AC systems mean potential problems for audio equipment.Ĭomputer guys have the same problem in their line of work and so forth. With term like ground loops: current running the equipment grounding conductor, metal within the building, and grounding electrode conductor. Sound and video people are referring to the type of noisy ground And the longer the wire the more noise it will pick up.

The reason a ground will not and never be perfectly noise free is that the grounding electrode conductor is nothing more than a long wire from point A to point B. The standard electrical grounding system throughout the building isn't designed to have current constantly flowing through it-and yet it does, you cannot stop it. With the exception of hospital systems, the definition is vague at best. The basics of all noise problems on the grounding system boils down to what is objectionable current. The bottom line is that a perfect "quiet" ground does not exist. Side must isolate the signal and grounds from the other. Loops, all signal grounds need to go to one common pointĪnd when two grounding points cannot be avoided, one Voltages which can cause damage, noise or 50Hz/60Hz Ground through different paths, a ground loop occurs.Ĭurrents flow through these multiple paths and develop

Professional audio systems just doesn't work This has spawned an industry for those who are now specialize in solving noise problems.Ī good power distribution system is essential for proper operation Since it doesn't come up every day, we all have limited practical experience. The dilemma is that solving "noise" problems is an art within itself. GB AUDIO Ground loops DATA SHEET on their web pages (with permission from me).
