How can you get 7.1 surround sound on non true hd system?

[belkincp]

If optical and coaxial can only go up to 5.1/6.1 surround sound, how can you carry 7.1 from ps3 to reciever?

Cus many speaker systems have 7.1 surround reciever and speaker system but no hdmi ability to get audio through the hdmi cable and decoded.

you have to use a decoder such as Dolby's Pro Logic IIx or DTS Neo:6. It's not discrete 6.1/7.1, but still sounds good. Besides that, HDMI is the only way the PS3 can output a true 7.1 signal, optical and coaxial don't have the bandwidth to support it, they can only support up to 1.5 mbps.

So toslink cannot carry actual 6.1/7.1 channels?
Just 5.1 and they dupicate or mesh certain channels together to create a virtual 7.1 surround?

 

[GlocksRock]

They can carry 6.1, as in Dolby Digital EX or DTS ES, but nothing above that. The only way to get TrueHD, Dolby Digital +, dts hd, dts-hd ma is with HDMI since they all need more than 1.5 mpbs of bandwidth. The receiver will use the PLIIx decoder to take redirect sounds from the surround channels, to the surround back channels in relation to what you are seeing on the display to create a 7.1 from a 5.1 source.

GlocksRock is the king of 7.1!!!

One of these days I will have to go back to 7.1 and get something for PLIIx just so I can have the same experience.

It really is nice... I was watching National Treasure 2 on blu ray last night, and when they were in the caves and the rocks were falling all around them, I felt like I was right in the middle of it, it was awesome. I wouldn't have had that same experince without the PLIIx, since it's only a 5.1 lossless track. It would still have sounded good, but it woudn't have surrounded me like it did.

Is "National Treasure 2" BD worth buying or just renting?

Yeah, why not do 7.1?

If you can turn every 5.1 movie into 7.1 with PLIIx, why not? More is good.

What about turning 2.0 movies into 7.1? Would you go that far? I mean that's really using some serious DSPs.

PLIIx is just using the side surrounds and turning that into the 4 surround speakers - without messing at all with the very important front 3 channels, which is great.

The second one is ok, it's very much like the first one, I would say it's worth a rent, but the first one is worth buying.

About turning 2.0 movies into 7.1, I would only see movies on tv broadcast in SD as being in 2.0 (stereo) but yes, I uses the PLIIx for all my tv watching wether it be a movie or whatever, I prefer to have the dialogue come from the center channel. Since the audio quality of that stuff isn't all that great to begin with, adding a little PLIIx processing isn't really going to make it sound any worse than it already does... PLIIx only redirects sounds, it does not alter them like DSPs do.
