    I just got a new dvd player, the Marantz DV-12S1 hooked up to my 49TX. As an added bonus, it supports dvd-a. According to the Pioneer manual, if I select the MULTI CH IN ADJUST option, the receiver will apply the settings that I have for the surround sound setup. Will this solve the BM and Time alignment issues? If it does, I am assuming that it converts the analogue output of the player to the digital domain to apply BM and TA. If I choose this option on the receiver, as opposed to the MULTI CH IN DIRECT option, am I losing the benefits of the hi rez tracks? Any opinions?

    Yes it will solve the BM and TA issues.
    Yes it does an a/d then d/a conversion.
    Not necessarily since most dvd-a's are copy protected they are converted to 48/24 when you use the analog outs of your dvd player. If you have a dvd-a that isn't copy protected (rare) then you would lose some quality, but then if they weren't copy protected then you could transfer them digitaly from your player and still get the hi resolution.

    Dan,thanks for the reply. Now I am even more confused. I was under the assumption that the only way to get the 96 or the 192 output of the source material was through the analog outs of the player before it is down converted to 48/24. Are you saying that if I use the MULTI CH ADJ option, all dvd-a source material will be converted to 48/24? If this is true, then I am assuming that I will lose a great deal of the sonic benefit of dvd-a, yes?

    Aaron and Dave, thanks for the replies, but please be patient, I just want to make sure I understand what is going on with my receiver. Am I correct in understanding that once I switch to the MULTI CH ADJ, the analog output of the player(96/24) is converted to a digital signal, manipulated for TA and BM,and down converted to 48/24? Hence losing the high res sonic advantage? Is this what happens when pairing the 49txi and the 47i? If this is the case, then the high res signal should be no better than using the MULTI CH ADJ option on my present receiver. Correct?

    I'm not that familiar with the particulars of the 49TX(I have a 45TX), so I'm not neccessarily saying it downconverts to 24/48 in the Multichannel Adjust mode(you'll have to consult your manual).

    The 49TXi & 47i do what we all wish we could do with our hi-res players--that is, send a digital out from the player, have the reciever do the BM & TA, and convert to analog just once like we do with DVD-V.

    For DVD-A you want to keep the signal path as short as possible without risking degredation by going analog->digital->analog, so the Multichannel Direct would be the way to go.

    Dave, thanks again. The manual does not state if the signal is down converted. In my original post I actually stated verbatium what was in the manual. I was hoping that someone here could give me the definitive answer. It seems to me that dvd-a and sacd were conceived in a half a##ed way. No wonder the general public could care less about these two formats.

    Ron, thanks. This is what I love about this forum:even when you think you know, you find out you don't. In the last year I found myself listening and worrying about the "numbers" and not the music. Thanks again for the reality slap. I should have mentioned that I have NHT2.5's in front, Audio center1, NHT SuperOne's in surround and a Deftech 200 sub. I think I am pretty happy with the way the system sounds......unless someone tells me otherwise!

    With my 49tx I use multi-channel adjust with dvd-a I think it sounds much more open,cleaner and just sounds better than direct, jmo.
