S/PDIF
Short for Sony/Philips Digital Interface, a standard audio file transfer format. S/
PDIF allows the transfer of digital audio signals from one device to another without
having to be converted first to an analog format. Maintaining the viability of a digital
signal prevents the quality of the signal from degrading when it is converted to analog.
Output Sampling Rate
   44.1KHz: This is recommend while playing CD
   48KHz: This is recommended while playing DVD or Dolby.
   96KHz: This is recommended while playing DVD-Audio.
Output Source
   Output digital audio source: The digital audio format (such as .wav, .mp3,.midi
   etc) will come out through S/PDIF-Out.
