HT gets more and more complicated.


Man this sure gets complicated.

I recently upgraded from my old AVR to a new DENON 3803, and man, there are alot of formats out there.

DD 5.1
DD 5.1EX
DTS
DTS ES
DTS ES Matrix
NEO:6

for crying out loud. My last Thx cert AVR was nowhere near this complicated.

The worst part, is that the DENON 3803's instruction manual totally sucks.
----------------------------------------
Here are some questions

1) Which is better? Dolby Digital 5.1? or DTS? Whats the difference?

2) I have a DVD audio player. Right now i have a coax digital interconnect connecting my DVD-A to the Denon, and i have set the DVD player to allow the Denon to do the decoding. Is this wrong? Will the Denon 3803 be able to properly decode the DVD-A discs, or will it decode the info as straight dvd? would it be better to use the 6 channel out from the dvd to the 6 channel input to the denon and let the panasonic DV-A7 DVD-a player do the decoding?

3) PCM is this Pulse Code Modulation?, is it a form of Time divsion multiplexing?

4) Im curious, my DVD manual says that i need to use BITSTREAM to send the data to the DENON. Then it talks about PCM down conversion where it changes the 96/24b signal to 44/18(i think). Is this degrading the sound quality? Does this actually convert it to a lower resolution signal? my DVD manual says i need to set the down conversion to YES.

5) does anyone who owns a DENON know what the AFDM option in the surround setup is? i cannot find anything in the manual about it.

1 - DD and DTS are competing formats and DTS has the edge on possible fidelity, by nature of higher sampling rates - should the engineer choose to use them. they are both compressed digital signals, but DTS's compression algorithm doesn't lose as much as the signal as DD. what it really comes down to, though, is who mixed it and how mch effort they put into it. they can both sound good when done right.

2 - you MUST use the 6-channel audio analog outputs from your dvd player if you want multichannel dvd-a. the digital connection will only pass standard PCM, DD, or DTS signal - not dvd-a. why? because of copy-protection issues. they won't allow the signat to be transfrered digitally for fear of somebody making perfect digital copies.

3 - yep, it's pulse code modulation. good 'ole PCM, like we use on CD's (and dvd-a)

4 - what you're referring to is specifically meant for 24/96 audio discs. some receivers can not handle the higher bitrate and don't know what to do with it, that is why they give you the option of downcoverting which would, yes, degrade the signal.. your denon has no such limitation, so don't worry about the downcoversion.

5 - i think AFDM stands for American Franco-Demolition-Marauders. this is the coalition of people in the government who have a secret network of citizens who are trying to make all American citizens hate all things French. if you are a REAL american, you will send me all of your french goods (wines, cheeses, uber-expensive audio equipment) for proper disposal and/or storage.

i'm not too sure about that last one, though.
dts neo:6 isn't a format per se - it's dts's version of prologic 2, or just an algorithm to extract multichannel from 2-channel sources.

as such, nothing will be "recorded" or "released" in neo:6

i use it on occasion, but for the most part prologic 2 does a better job on tv broadcasts and the sort. don't ever use either for music. it's not good.
