Hum/Ground Loop Issues

I suggest creating a separate saloon, a one-stop-shop, to collect questions and solutions regarding hum and ground loop problems. This would allow those with a hum issue to research how others have dealt with the problem and share their own solutions.

These problems crop up fairly often and range from easy to very difficult to diagnose. We've discussed in this forum everything from cable TV induced ground loops to the oddities of having a wind powered generator as part of your electrical system! Just my 2 cents, but I think the collective experience of the Gunslingers on this topic in a single location would help a lot of folks.

This is a pretty interesting idea, AvFan. It could be a good resource.

An excellent idea. Perhaps the outlaws would not only create such a saloon...but..it would be helpful to those with hum if previous posts dealing with it could be moved there.

GL problems can be a nightmare that's for sure. Many use cheater plugs or filters as a quick fix. Not a good idea. Find the source or sources.

For you HT types, your cable tv input could be the source.

All my equipment use balanced ins and outs . I make my own interconnects using Canare bi-wire cable and drop pin 1 at the input of each amp or signal processor (called telescoping interconnects). This is a common practice in recording studio wiring schematics.

Make sure the whole system is plugged into the same power source (outlet). A 20-30 amp dedicated line is great.

If you use balanced lines and do the above your system will be dead silent (depending on the quality of your components).
