dvd-audio is 96 khz, correct?
i bought a dvd-audio player yesterday and have hooked up the analog connections.
when i play a dvd-audio, and press multi channel on my reciever, the suuround sound is not as good as prologic II
i went into my dvd-audio player setup menu and have sellected multichannel.
but for some reason, multi channel on dvd-audio does not sound as good as PLII
i looked in my reciever manual and it says this:
IF 96 KHZ DIGITAL SIGNAL IS IMPUT, THE TONE, SOUND FIELD AND SURROUND PARAMETERS DO NOT FUNCTION
can someone explain that or give me advice.
thanks
player is panasonic f-85

Jeremy: go buy Linkin Park's Reanimation dvd-audio and THEN you'll hear what dvd-audio is capable of.
Each surround music disc is mixed differently: some "gentle" & airy, and some in-your-face and moving all around the room, like that LP disc.

not all DVD-A is 96kHz; the DVD-A standard is PCM at sampling rates of 44.1, 48.0, 88.2, 96.0, 176.4 and 192.0 kHz, with word lengths of 16, 20 or 24 bits. Unless the disc specifically states 96/24 I would imagine most 5.1 DVD-A is at 48/20(?) with hirez stereo at 192/24

i have the linkin park dvd-audio playing right now, and if i press the audio button on my remote, it says this:
48k24b 6ch
now like you said, why would hirez stereo be higher?

Jeremy
I don't have this disc, but you could try out the stereo layer instead of the m/c area and see what the resolution is 
as to why.. my guess is they would have put 6ch of 192/24 if there was enough space on the disc.
post edit: I found this page that says the 2ch hirez is - even less than mc - 44k/24b. This is probably what you see printed on top at the back of the DVD-A package

Jeremy,
Have you done level setting for the analog output of your Panasonic player? If you haven't you likely have channel imbalances that are causing some of your issues.
Also, if you truly are using the multi-channel analog output, this statement
Quote:

is irrelevant, as you are working with an analog signal.
The reason for not providing these functions on 96K digital inputs, would be that there is insufficient DSP horsepower to perform the operations for that sampling rate.
BTW, there is no mandated sampling rate for DVD-Audio. For multi-channel material, the rates can be 44.1K, 48K, 88.2K and 96K. For stereo (or mono) material add 176.4K and 192K.
Delivered sampling rates can depend on existing master tapes. If digital, there is little benefit in modifying the original sampling rates. For analog, it will depend on the quality of those tapes, the mixing and mastering studios utilized and the discretion of the team responsible for the technical aspects of the recording.
Some of my better sounding DVD-A titles are delivered as "only" 48K sampling.
