i was reading some stuff and i read about 6.1 and 7.1 surround sound. now, im pretty sure that in a 6.1 the extra channel is like a center rear right? or am i wrong and how exactly would that work? and what about a 7.1 system? what would that be? any one have any good links that tell all about what different decoders do and such(dolby dts, thx, bla bla bla)? any info would be nice.
You know, this might sound odd, but you might have dual front centers in the 7.1 system. It very well could be 2 centers (one left, one right) for the front, and one for the rear.
I'm not sure... It certainly sounds interesting, though. :)
No...not dual front centers....
It's a different way to get rear sounds....
Whenever these channels are added, generally, it's to get a more immersive rear sound.... with 7.1, you have four speakers roughly behind you, and I believe the ones closer to the center are matrixed from the other two.. with 6.1, you have a speaker directly behind you...
I suggest you ask about this stuff at avsforum, or any of the many home theater forums.
The Game Theater XP theoretically supports this.
isn't 6.1 set up like the 6 on a set of dice? Two front mains, one center, two rears, two more speakers centered between the front and back on the sides of the room(As one channel split between the two), and plus the subwoofer. But No definately not two center channels LOL that wouldn't be a center any more it would be left and right. ;)
if you are the center of the clock, 6.1 is like this...
speakers at 12, 1:30, 4:30, 6, 7:30, 10:30.
7.1 should be like this...
speakers at 12, 1:30, 4, 5, 7, 8, 10:30
Don't quote me on that. I don't know for sure.
A 6.1 setup puts a speaker directly behind you.
Here's a diagram I found of a 7.1 setup.

There's a lot to cover when it comes to decoders and codecs. Here's a quick link on DTS. http://www.home-cinema.de/dts/dtsfaq.htm
hey cool, you guys dont disapoint! thanks alot. if any of you find out anything more just keep posting!
Well, I think that link of mine about THX-EX and DTS-ES helps a lot...
yeah it did. they both did. but what i found interesting was this:Quote:

"When George Lucas decided he wanted a 360-degree pan for the pod race in Star Wars Episode I: The Phantom Menace, he created an add-on to the Dolby Digital format called THX-EX. A center, surround speaker is added to give the user 3 channels in front, and 3 behind. The signal for the center surround is matrixed onto the signals for the right and left surrounds, and derived by a receiver in the same way that a pro-logic receiver derives the front center channel. You can either buy a THX-EX receiver, which at print time is quite expensive, or pre-amp out your surround channels (if your Dolby Digital receiver has pre-amp outs for the surrounds) to a pro-logic receiver to derive the 7th channel."
so that pretty much means that you really dont need a 6.1 or a 7.1 setup? i mean, if they can use an add on to Dolby Digital(THX-EX) to kinda "emulate" the extra channels, then why the hell would we want to pay for all those extra speakers and so on? if they can do it all through decoding.......
:confused: :confused:
Well, supposedly, the emulation helps a LOT with rear imaging...
You know, allowing rear speakers to do both the non-localized ambient stuff (like dipoles do) and localized positional stuff?
What about what they said about DTS-ES??
Regardless... multimedia setups generally are made to localize sounds... so I dunno.
They are compensating for one specific quirck of a home theater setup... what quirk, I don't exactly know. What I do know is that, with these near-field setups, I don't really CARE...
"DTS followed suit, and introduced DTS ES, a 7-channel format. There are 2 varieties of DTS ES. The first is a matrix format, in which the 7th channel is encoded into the left and right surround channels like THX EX. The other format is a discrete 7-channel format. The discrete DTS ES format cannot be decoded in a DIY setup using a pro-logic receiver.Quote:

Both THX EX and DTS ES down-convert perfectly to 5.1, so if you are not interested in upgrading to 6.1 or 7.1 (the surround center channel is sometimes amplified twice to allow for larger rooms), your 5.1 setup will be more than adequate."
thats what it said :D so its pretty much using the decoding software and such to make these "phantom" channels. i find that cool. and it makes me even more suprised why they would want to have 6.1 and 7.1 setups if they can do it all and do it well with encoding. and the funny thing is, it does most of it with the rear channels. so us people with 4.1 systems are left in the dark :p. I think its time to go get Star Wars:Episode 1 from my friend and watch it(especially the pod racing!).
There's not many DVD titles that I know of which support 7.1 or even 6.1 setups -- that is with discrete channels.Quote:

Sure, you could upmix a 5.1 source to 6 or 7 channels or even more but that would pretty much defeat the purpose of owning such a setup. You'd also need a compliant receiver/decoder for doing as such.
Well, assuming someone had enough money to toss around to get a system like that, I'm sure they wouldn't be using a receiver, and more than likely using a pre/power amp dj/theatre (not home theatre) system. :)Quote:

yeah, thats what im kinda baffled about. but if you read my other post i had that quote and it said that you dont need a receiver/decoder to have 6.1/7.1 sound. thats what thx-ex and the like do and it downmixes to the current 5.1. but yet, there are still 6.1 and 7.1 systems out there......Quote:
