#1

I am putting together a cable tv box with my amplifier, dvd, and tv. In a diagram made for me, there is an optical line that runs from the cable tv box to the amplifier/receiver. What is this optical line actually do? Hope not to dumb a question.

I believe that you are talking about the fiber optic cable, which transfers your audio (sound), in a high quality format.
