Speaker-level signals are relatively immune from induced noise. Conduit is not necessary, and sometimes bad. Crossing power wires is no problem, even for coax. Just avoid parallel runs within a few inches and for several feet.
Originally posted by nzkiwi71 Another question: In my neck of the words, I have to use conduit (thin-wall) in my basement for the electrical (i.e. no romex allowed). Does this thin-wall conduit limit the amount of interference that is often caused by running HT cables (e.g. audio, video, etc.) too close to electrical wiring? |
