There is a constant barrage of electrical noise in this world! Cell phones,
wireless devices, radio/video transmitters, electrical lines, etc.

The thing to do is use shielded speaker wire or shielded Cat 5 wire! Then
just ground the shield at one end to prevent ground loops.

Protect the things which are sensitive to outside interference. That is much
easier.

Hi,

So I've learned that electrical wires can cause 60hz interference if
running along side speaker wire or intercom Cat 5. Are there any good
shielding ideas like using some kind of shielded conduit or wrapping wires
in foil or something like that? Please help point me in the right
direction.

Thanks,

Aaron
