What is coaxial audio output ?

Question

Does 1 RCA plug from the DVD Player's COAXIAL DIGITAL AUDIO OUT to the Reciever's COAXIAL DIGITAL AUDIO IN work the same or better than using all 6 RCA Plugs including the SUBWOOFER OUT into the Reciever? And if so how does that work ? Wouldn't 6 be better than 1. And also why would they make the 6 RCA plugs for on the back of DVD Players or Recievers? Why not just have the COXIAL DIGITAL AUDIO?

Answer 1

With one cable (the output is called s/pdif) the Receiver is doing all the work - taking 5.1 channels and decoding it.

With 6 cables, the DVD player is doing all the decoding.  This is for people with no AV receiver.  Since you have an AV receiver, just use the coax output.

Answer 2

just use the single one it will work well the others are for any things that dont  have a single coaxil input

Answer 3

Most of the time the digital coaxial out is a good compromise.  However, if you have a player that plays SACD or DVD-Audio, those formats only output through the analog cables to your receiver.  This is because these formats will play the music uncompressed for higher fidelity.  If you do not have a SACD or DVD-Audion player than use the coaxial digital out or the optical digital out.
