    I recently bought a refurb'd Harman Kardon AVR-525. I've got it connected with 7.1 speakers. The manual is very vague when talking about the different surround modes though.

    I know what DTS and DD is when it comes to DVD's, so no problem there.

    But when listening to music or analog audio/video programs (like VCR tapes or cable TV), the surround modes are kinda confusing.

    All my analog programming defaults to Logic 7, Harman Kardon's own surround sound that reproduces 7.1 channel sound from RCA inputs. Available in both Music and Cinema modes.

    Then there's DTS-NEO 6 which sounds louder than the rest, also available in Music and Cinema modes.

    Then there's good ole Dolby Pro Logic II which doesn't use 7.1 speakers, it only outputs sound to 5.1. Also available in Music and Cinema modes as well as "Emulation" which makes it act like original Pro Logic 4 channel (who would want that anyway?)

    What are the pros and cons of each of these and which one is best to use for music and movies? I've tried flipping between all of them, but I'm having trouble figuring out which is the "best", so I was hoping for some expert analysis of these surround sound modes since their description is vague in the manual.

    Thanks!

    Thanks for the reply.

    What's the technology used though?

    Is DTS-NEO 6 vs. Dolby Pro Logic II in the analog world comparable to DTS vs. Dolby Digital in the digital world? Is Logic 7 anything like DPLII, does it use any of the same methods of surround or is this some new surround method that H/K is using?

    AFAIK, all of these modes are digital. Even with analog sources, no one does surround processing in the analog realm these days.

    As for the differences, I can't claim to have studied the technical specs (to the extent they're even available; remember that these are proprietary methods). I think Dolby has some technical papers on DPL2 at their website. And Lexicon has published at least one technical paper on Logic7.
