Atmos vs 5.1

[stoopid]

Just so if I am understanding this correctly, if I make a 7.1 AVCHD disc using DTSMA with discrete info in each channel and give it to a friend who only has a 5.1 system, he will still hear all the information. Nothing will be lost. Correct?

That's my understanding.

Nothing is thrown away. In DTS HD MA 7.1 the rear information is already in the surround channels. So to play in 5.1 the rears are simply discarded, whereas to play in 7.1 the rears information is subtracted from the surround channels to derive what is played in the surround speakers. Nothing is lost. It's the same kind of scheme that is used by Atmos for the height data.

OK, that's not the way I read your original post, very confusing this stuff.

For example, with DTS HD MA to go from 7.1 to 5.1 the rear channels are discarded because everything has to be in the 5.1 core which includes the surrounds.

I’ll be having my dear old 7701 for sale in a week or so.

I don't see any prices listed?
Anyhow, hope you get a good price, the AV770x have always been great pre-pro's.
I owned a 7701 for a long time till I sold it to buy the 7703, I wanted Atmos and other things.
A friend of mine on another site has my ole 7701 and its still running perfectly.
Well built components!

I was quoted $2879. Undoubtedly plus tax, and I'd be surprised if I get to take it home today. But I'll find out in a couple of hours. First, I have to log down all my settings in my 7701. I've personalized it quite a bit, and I don't want to have to go through all that "try this, try that" again. Hell, it's taken me a decade to get it JUST RIGHT!

That sounds good for a "new in sealed box" unit, be sure.

As to the rest, good luck. So much has changed I doubt much will transfer.
No harm in trying.
