Differences in sound quality between a rca and a digital audio connection?
Hello,
I have a tv hooked up to my receiver via a RCA connection for surround sound (analog). My question is, if I connect to the receiver via a digital audio connection instead (optical TOSLINK connection, or digital audio coaxial) will I notice a significant difference in the sound?
Yes , but it depends on the show/movie you are watching.
The L/R analog cables can carry stereo or Dolby Pro Logic. This breaks dialog to a center speaker, and BOTH rear speakers get the same sounds with a limited frequency range.
The digital connection can carry true 5.1. Totally separate sound channels to each of 5 speakers.
For a modern movie with 5.1 sound - the difference in surround effects can be dramatic. For generic Broadast television - it may not be so noticeable.
It all depends on how much time they spent creating the 5.1 mix for the show you are watching.
It is recommended you use a digital connection. 5.1 is the current HDTV standard and you are missing out with L/R analog wires.
