Need help in understanding surround sound

10 years ago

I have had a surround sound system for several years and am still confused about all the options available to me on my receiver. I understand that movies may have the extra sound channels encoded and for best results, I should use the same decoding system. But that information is usually not apparent to me. Also, what happens if my source is not encoded, such as for a CD or analog radio. Are TV broadcast movies encoded? Usually, I just switch between the various encodings until it sounds best. My receiver has 17 different DSP programs.

If you are getting HDTV over the air or by cable, it may have surround sound encoded into it. You'd have to consult your cable provider. I'm not sure about broadcast TV these days, I'm more into obsolete technology than current. If you were to Google "Does HDTV have surround sound?" you will find some stuff to read.

Recorded movies (DVDs) should have a logo or other info printed on them indicating whether they have Dolby surround, standard stereo, mono, etc.

Cd and radio are two channel music and should be played that way, IMHO. If you like something other than two channel, like Concert Hall or Jazz Club settings, by all means use them.

Most movies and many TV shows are encoded in Dolby Digital (5.1), personally I don't care for DSP processing so if you're listening to music, use a multi channel stereo mode or Stereo Direct. If a DVD or Blu-ray has DTS option audio track, try that. It uses less compression and more dynamic than DD
