Robin,
You are confusing a back center channel (like a 6.1 setup with Dolby EX) with a true 7.1 setup where the back surrounds are separate and distinct.  Not sure why you are using "center" so often in this discussion...it's only relevant in 6.1 setups..something no one on this thread has mentioned or set up.

No I'm not confused, I simply have a 6.1 system. :lol: Even so, I personally would still look at a7.1 system as having 2 rear "center" channel speakers and I feel using the word "center" does an adeguate job at differentiating the 6/7 channels from the actual surround channels 4/5.
I'm sorry you have an issue with the way I look at things Ted but it makes perfect sense to me. :D

Cheers,
Robin

Robin,
I wasn't meaning to have an issue; sorry you took it that way.  All I was saying is that the OP was asking about 7.1 and you were talking rear center speaker(s).  The rear speakers in a true 7.1 setup (or even good 5.1 to 7.1 matrixing algorithms like Logic7 or good DPLIIx) are indeed distinct non-mono info, steered or discrete. 



No problems Ted, I chalk it up to a tomato/tomatoe thingie. My consensus was I'd consider the surround speakers(4/5) as side surrounds on a 7.1 receiver before I'd consider the back surrounds(6/7) as the sides. And I still do. :D

Cheers,
Robin

You mean like this: http://www.dolby.com/consumer/technology/dolby_ex.html

See diagrams

Or this: http://www.dolby.com/consumer/technology/prologic_IIx_faq_1.html

Which is a matrix, made up pseudo "stereo".

No, of course not.  Dolby EX, as per the diagram, is a 6.1 setup, period; that's its definition.  Mono rear center speaker.  If you use dual speakers in back for EX they're mono too. 

True 7.1 sources like TrueHD 7.1 or DTS HD MA 7.1 (or even uncompressed pcm 7.1) the back speakers are being fed unique signals each, and quite noticeable in good soundtracks.  In matrixed codecs like Dolby PLIIx the back speakers are also being fed unique signals but they are derived or matrixed from the surrounds (things like steered effects as they move).  This is especially noticeable in aircrat or spaceship fly-bys, foley effect like bullets whizzing by, thunderstorms, etc.  That's why Dolby recommends, for PLIIX and above (Digital plus, TrueHD, etc.), to place the back surrounds at 135-150 degrees, leaving from 30 to 50 degrees between back l and back r.  They are not mono, they are not centered.

  Back as the sides??   Nobody does.

Robin,

Ted is correct and helped answer the original poster.

Why can't you accept that and move on?

BTW, I love the way BIG BLUE is kicking Dallas' ass all over the field!!

Outside of Eli's mistake, it would be a shutout.

Nice quack of a pass by Bollinger...can you say DOMINATION??

Now c'mon Robin, are you just doing this on purpose!!??  The OP asked, we set him straight (very early on as you might recall) then this back center channel mono thing (which is all about 6.1, NOT 7.1) came up.  I tried to steer it back to a 7.1 discussion, and I quoted Dolby, etc.   Now I'm sorry i got involved.

Thanks for all the input and advice. I made sure my Onkyo knows that I have a 5.1 speaker setup and it seems to work fine. I just wanted to make sure I wasn't missing something.

I rarely watch movies. I do watch concerts. More and more have become available in Blu Ray.

Anyway, didn't mean to start anything.

Peace  :wink:

Hey DR,
You may find an occasional movie that has a "THX Optimizer" in the menu.
If you play these tones, it will tell you if you've got things wires up correctly.

Bob

p.s. If memory serves, Star Wars 4,5,6 have these in the menu.
