When I say "RCA", I mean the standard connections one might find on the back of a dvd player. RCA connector cable, also referred to as a phono connector or Cinch connector is sold precut at Radio Shack, Fry's, Staples and Target. It comes in 50, 60 and 100 foot lengths. Sometimes it has the type of cable one would find that transfers low voltage from adapters. This is the type I use. The corresponding plug is called an RCA plug or a phono plug. The RCA cable I purchased came with a power cable, a white RCA plug and a yellow RCA plug. I used the yellow RCA plug for the connection. I used the power cable to transfer 9 volts. The white RCA plug was left unused. The signal was very strong and I was more than satisfied. Then one day out of sheer confusion I switched the RCA plug used from yellow to white at the end of the device used. At my end, the opposite end, the yellow RCA plug was still in use. But when I decided to use my apparatus again, I got a signal but it was only 1/3 as strong. This led me to the horrifying discovery that the signal sent down the white RCA plug was now infiltrating to the wire terminationg at the yellow RCA plug!! How is this happening? Is RCA cable sold that prevents this from happening? Does the power cable that lays side by side with the two RCA cables have any influence on this type of phenomenon?
