Set the first AVR to 9.1.2 (but don't connect any of the height speakers) and set the second to 5.1.4 (connect only the height speakers).

This whole thread is one of my favorites to read. A long while ago I thought, mistakenly so, that I was the first to think up this solution of using two processors together for an added channel count and was quickly told it would never work by others. Then I found this thread and a big smile rolled across my face after learning others were not only thinking the same thing but actually did it. My question for the ones out there actually doing this is: if you can choose any Marantz equipment can you make 9.1.8 work and actually make it sound right? Which components would you use for which channels (ex: 9.x.2 from one and x.x.4 from the other)?

It makes sense to me that you could possibly make a 9.1.4 and hopefully all the timing is accurate between two processors and the projector and it works. I could even bite off on the thought of 9.1.6 if you use the .2 heights from one processor and the .4 from another processor. But, is there any way to accurately go to 9.1.8? I have not found any portion of setup in my current Marantz 8801 that allows me to play with timing (lip sync) of any speaker. It might be there and maybe I have not seen it. I suppose if you could minimally slow down the one pair of ceiling speakers that might work but only for objects coming to you, not going away from you. I'm curious (and hoping) I have it all wrong and there is a solution out there. I've been waiting one year to upgrade my processor and I'm growing frustrated. My current option is only the Trinnov Altitude and I'm just not sure the juice is worth the squeeze when it comes to spending that much on the one HT item that seems to become obsolete the fastest, at least lately.

Any thoughts for the experts who've done this? Which Marantz items would you buy, maybe two 8802's for the best solution? Is there a solution for 9.1.8 and does it really work? Thanks all.

I think matrixing TM for 9.1.6 is going to be the most accurate for anything over x.x.4. This way the two units won't be fighting themselves for sound positioning, but wait for Scott and some others to chime in.

*Warning* None of my suggestions, ideas or even thoughts have any WAF, in any way!

Here's the thing... I didn't think x.x.6 was the magic number just because I like it. In actual use, it's the most realistic choice for extended surround systems.

All you need is two cheap-ass receiver (preferably identical) to do PL2 decoding. That's easy, cheap and very common.

Attempting to go beyond that.... you're just asking for high prices, hard to find gear and even more complex setup. All with likely little benefit.

I've watched as interest in these extended surround immersive setups gain quite a bit. People want to jump right into it. While it is relatively easy to configure and live with, it IS very much added complexity to an already complex setup. For a lot of people it's hard enough setting up a 7.1 system let alone a "regular" 7.1.4 system. Then tack on not one but TWO more AVR's and dual stereo line outs and then a pair of triple speaker outputs PER secondary AVR. It's quite a configuration. Many people come in here and ask questions they really shouldn't be asking if they are actually thinking they will attempt to install one of these extended immersive systems. These people are NOT ready for these systems, imho.

It's a lot to take on. Not for beginners.

Seriously, live with 7.1.6 audio for a while and then think about even attempting something beyond that. Most likely... you won't.

Hi Scott. Thanks for the info. Although I don't consider myself an expert, after building my current theater (see build thread link below) I'm not sure if I consider myself a "beginner" either. That said, I'll look through the thread for more details so I don't reinvent the wheel since I've only read a portion of the total thread. This thread, as I mentioned before, is great! Keep up the great work as you continue to experiment. Ultimately, I'm still hoping a true solution comes out (like the Trinnov) that doesn't cost an arm and a leg. Take care.

Just go with the Trinnow unless you want to wait 5+ years. And to be fair a Trinnow would match your current HT setup nicely.

No reason to have 2 8802's as the second AVR/Pre-Pro only needs to support 5.1.4. You can pick something pretty basic, as you'll only be powering 4 height channels with it, which don't need a lot of juice.

9.1.8, from what I'm reading - no. First unit is set to 9.12, second unit set at 5.1.4, that only gets you to 9.1.6.

Edit: Looked at your setup. Just get a Trinnov dude!

That will give you 9.1.4, to get .6 you need to use PLII or similar to expand the heights.

musing to myself

so if you put the TFL and TFR thru the same extraction, do you get a TFM, and of course, for the TR's eventually a TRM, only 2 more AVR's,

an equidistanace Octagon, wrt one seater MLP and a much larger space, which I don't have

Yes you can but don't matrix an already matrixed output. Never cascade the processing.

I've thought about trying a single center front height but I just haven't got to that ...yet.

Thanks guys!!! Truly appreciated. The only problem I see with the Trinnov and other similar processors remains the update cycle. I can use my K system for years and my oppo and other gear for years as well, and my Bryston amps for a VERY long time as well.... But how long will the Trinnov's hardware remain compatible and remain the centerpiece of a high end system? I'll be interested to see if anything new comes out in the next few months.

The trinnov is software based running a top of the range Intel processor. Unless they cease trading I don't see them ever become obsolete.

from @Scott Simonian : Yes you can but don't matrix an already matrixed output. Never cascade the processing.

correctamundo , split the TF preouts, 1 set and that AVR to do the TM extraction,
and a 3rd AVR to do the TFC, just don't hook up any other speakers to that AVR

would that 3rd AVR actually be able to provide output for the TFC without a "left and right"

something to think about in this heat . . . .

As you point out, ProLogic II and Dolby-EX cannot be used simultaneously to matrix both a front center channel and a Surround Back channel from a discrete 4-channel input signal. It's one or the other. (Though ProLogic IIx could matrix both speakers from a 2-channel input signal.)

In fact, would PLII ever matrix a front center at all from a 4-channel signal?

That said, would the Dolby Surround Upmixer be able to do this? If you tell an Atmos-capable receiver that you have a 6.1 configuration (3 channels across the front, 2 surrounds, and 1 surround back), and feed it a discrete 4-channel signal through the analog inputs (front left/right, surround left/right), will it matrix both the front center and surround back?

But then it wouldn't be extracting a centre out (mono surround-back out) from discrete channels plugged into the surround jacks of the 5.1/7.1 input. Of the 4 channels plugged into the multi-channel input, only 2 would get processed.
Quote:

It can't. The PLII family of processing (PLII, PLIIx, PLIIz) always "sees" only 2 input channels. When fed a 2-channel input, the upmixer sees 2 main channels and creates up to 9 outputs (depending on speaker configuration). When fed a multi-channel input (like your 4-channel example), it only sees 2 surround channels and creates 3 to 6 outputs (the front channels are never touched).

It won't extract a centre output from a multi-channel source, just surround-backs and heights.

It doesn't surprise me that this wouldn't work. However, I thought the intent of DSU was to take any input signal you feed it (up to 7.1) and spread it to however many speakers you tell the processor you have.

Not quite 'however many'. For example, of the 24 possible floor speakers in the home Atmos spec, only 17 get upmixed signals (the centre rear, two wides and four screen speakers between the L/C/R are never fed by DSU).

Maybe because of their close ties to the movie industry, Dolby tends to be more mindful of original intent when it comes to upmixing, which is why DSU is noticeably less aggressive when feeding heights compared to Neural:X and Auro-Matic. To that end, if the centre channel of a discrete multi-channel mix contains no info (like your 4-channel example), then they figure that was a deliberate choice and therefore make no attempt to change it.

Well, those speakers do get matrixed sounds when the input signal is 2-channel.

I suppose that's logical enough. It's just disappointing for this unconventional exercise we're attempting here.

Not in my experience; at least with wides.

DSU doesn't use the wides at all. That much is known. However, I assume it would pull a center channel, surrounds and surround backs from a 2-channel source. Even ProLogic IIx could do that.

Those aren't the speakers I mentioned.

Aside from not using the two wides, DSU also doesn't use the centre rear and the four screen speakers that are between the L/C/R speakers. Of the 24 speakers on the lower plane, only 17 are used by DSU.

Correct, when you have a 7.1 setup. However, DSU will not simulate audio to a single rear surround (ie. 6.1 setup).

Interesting info, Sanjay and JD. Thanks.

Now, does anyone know what Neo:X or Neural:X would do in this situation?

We already know that both those upmixers support wides. Doubt that either one can simultaneously extract a front centre AND surround-back from a 4-channel source (I'm assuming that's what you meant by "this situation"). But I'll do a little digging and see if I can get a definitive answer either way.

Neither has any such limitation ... both will play to the single rear surround as noted by the missing note *4 I previously posted for DSU.

But can they matrix a front center from a 4-channel source? I assume not, for the same reason Dolby doesn't.
