Axiom Home Page Forums General Discussion Home Theater 7.1 DTS HD Master Audio

I wasn't aware that there were any movies out in this sound format as of yet, so I was surprised when we watched the Golden Compass in Blu-ray tonight and saw that my PS3 was outputting it in 7.1 Dts-HD MA, are there any other recent movies with a 7.1 sountrack?

So how cool was it?

Michael, just curious how you actually saw that. Doesn't the PS3 output HD audio as multichannel PCM?

It shows up on the actual PS3 display when you call it up. It tells you the bitrate of the video, audio, etc, as well as all the codecs playing in those areas.

Okay Steve. Actually what Michael meant then was that the PS3 was playing the 7.1 DTS HD Master Audio track, not that it was outputting it in that bitstream form.

oh no i was responding to you JohnK, I should have specified that yes it does output Multichannel PCM, however you can see it on the PS3's onscreen display which codec it is decoding to Multichannel PCM. it will not bitstream DTS HD MA. I apologize for any confusion/frustration that I may have caused.

I was trying to tell you how he saw the DTS HD MA although it did output as LPCM

Yeah Steve, that's how I understood your first reply, so no problem.

It's finals week, my brain is scrambled, and i get so excited when there is a question I actually know how to answer! thanks for being understanding, and happy playstationing

Exactly John, the PS3 was decoding or playing it and and sending it to the receiver via PCM.
The movie sounded terrific, but I was watching at fairly low volume levels, tommorrow I'll crank it up when no one is home to get a better idea of how it sounds through the six speakers and sub. One question I have is will my Denon 4806 play it as a true 7.1 by PCM via HDMI or is it limited to 6.1

Michael, I'm confident that the Denon manual explains that clearly(hah!), but I'd think that if 7 discrete channels are received, then 7 would be output for a 7.1 speaker setup. The 4306's display should indicate the number of channels that it's actually receiving.

Mine says "7.1 multichannel in" when receiving such signals. If you've got that on the Denon, you're in good shape.

For PCM 7.1, my Denon 3808 also displays '7.1 Muntichannel.' For DTS or DD TrueHD in 7.1 it displays those as DTS 7.1 or DD TrueHD. I love it when all those little speaker indicators for input and output all light up.

New Line encodes some of their discs funny. The PS3 will only output DTS HD MA 5.1 on certain DTS HD MA 7.1 discs. It's not the PS3's fault, but the way the discs are encoded.

here is a link you can use to filter by audio type

just select DTS HD MA 7.1 from the audio drop down and click on filter. It will then show you all movies in that audio format, there are several.

Here is a thread that discusses the New Line encoding issue and which discs are affected:

Thanks!

I can't wait to see the golden compass. The only DTS HD MA 7.1 movie i've seen so far is Mr Woodcock and obviously it did not use the extra channels to their full extent, just like any other comedy movie. By the way, I too have a PS3.

Whoa, calm down, there, vassillios, this is a family forum!

I was able to watch the movie at my preferred listening levels this afternoon and it really sounded good. Who would have thought, 7.1 DTS-HD Master Audio, sweet!

Pan's Labyrinth is also DTS:HD MA 7.1. When the pixies are flying all around (including behind), the effect is pretty amazing.

Home dad, which movie do you speak of? Golden Compass?

Yes, it was also a pretty good movie.
