Coaxial & Optical
Both of these connections are for running the Digital soundtrack of the movie into a Digital amplifier or decoder for Digital Surround Sound. If only a short run is required from the DVD to the amp, we'd recommend using coaxial. If a longer cable is required (up to 10m) we'd suggest using optical as it is clearly better over very long distances. All sound information (including ordinary stereo and Pro-Logic sound) will be passed down these cables. See also: Coax versus optical digital debate.
