DolbyTruHD on Pionneer VSX9040TXH

[platinum]

Hi all. When I watch the BD with Dolby TruHD audio track, my Pioneer VSX-9040TXH receiver always shows "HD +PLIIx Movie" audio format. How do i get only real Dolby TruHD?
Note: with DTS DH MA tracks, it shows as is. Why the receiver does not show Dolby TruHD when playing Dolby TruHD disc?

Thanks for your help.

That is weird.....someone else had this same issue and we couldn't figure it out then either...

The only thing I can think of is what blu-ray are you trying to play? Some blu-rays do not default to HD audio, and The Dark Knight is one of them. You would need to select it in the players menu before starting.

I'm not familiar with your receiver so this is just a guess. I think you may have Dolby Pro-Logic IIx activated. You'll need the receiver to be in "auto surround" mode. This allows the receiver to automatically detect whatever format you are sending from your player.

But he can get DTS-HD MA to show up, so his situation doesn't make much sense....nor did it the last time....

The clue is that "PLIIx Movie" is displayed. This could indicate that "Pro Logic IIx Movie" was chosen from the Standard Surround Sound menu (ex. STANDARD button on the remote). I'm suggesting that the OP try the S. DIRECT (this is for AUTO SURR/STREAM DIRECT) button on the remote. AFAIK, the "Pro Logic IIx Movie" setting in the Standard Surround Sound menu does not affect the DTS-HD MA settings which is why he could see that displayed if playing a different BD with DTS-HD MA.

I agree with you ManUtd. Also I have the Pioneer VSX-LX50 (model for Europe and Latin America) and I have to turn off the surround back to get DD True Hd, Otherwise the receiver displayed HD+PLIIx + Movie as Platinum said. Maybe that happens because Dolby True HD and Dolby Pro logic IIx is the same format

Apparently, these models must have been developed differently than American ones, as there is no such issue on any I am familiar with here in the US.

Hi Fors, Yes I think Pioneer LX series is the same as Elite series. Check this link http://www.pioneer.eu/eur/products/4.../overview.html

My receiver is always set for "auto surround". And the surround back is ON, too. Next time when rent a BD with Dolby TruHD, i'll try to turn off the surround back option.
Fortunately, not many BDs have Dolby TruHD. Most of them are DTS HD MA.
Thanks again for your comments.
n.b: the 9040 is nearly same as the Elite 21 model.

Let us know.

Yesterday, I watched "Streisand: Live in Concert 2006" with LPCM 5.1 format. On the display of my receiver, it shows "PCM +PLIIx MV".
I wonder why I always get this extra PLIIx mixed with the original format?

Hi Platinum,
That happens when you have the SBCH ON, set SBCH OFF or AUTO, also you could press twice AUTO SURROUND mode (Strem Direct) three time is (pure direct) the get PCM (only) displayed in your receiver. The next time when you turn on your receiver the SBCH is OFF if you set in off the last time.

In my case when I want to use my surround back I set SBCH ON (PCM + PLIIx MV or True + PLIIx + MV or DTS + PLIIx + MV or DD + PLIIx + MV. Depends of the movie format.

I refer AUTO SURROUND mode (S. Direct button)

TCR Alliance, I forgot to set off the SurrBack function yesterday. Thanks for your reminder

- For my education:
If I watch movies and keep these formats displayed on the receiver - i.e PCM + PLIIx MV or True + PLIIx + MV or DTS + PLIIx + MV or DD + PLIIx + MV - do I still stay with the LOSSLESS audio?

If you have a 6.1 or 7.1 system, there's no problem with using PLIIx or a similar DSP to matrix sound for the rear speaker(s). You still get lossless. But, your receiver uses matrix processing to reroute some of the surround audio to the back channel(s).

If you don't want rear channel audio from 5.1 sources, disengage the DSP in your receiver. The manual will explain how to do that. I would not recommend using Direct or Pure Direct settings since those also bypass bass management and EQ.

If I recall correctly, some (all?) Pioneers will not apply Dolby DSPs to DTS sources. Pioneers are unusual in that way. That would explain why you see Dolby PLIIx for TrueHD and PCM sources, but not for dts-MA sources. You should be able to use DTS Neo:6 or DTS-ES processing to matrix rear channel audio from 5.1 DTS sources.

Here's a quick explanation of how digital audio processing works: the player sends the audio to the receiver as PCM or as an encoded file such as TrueHD or dts-MA. If the audio is encoded, the receiver decodes the file back into PCM. So, you end up with PCM either way. Then, the receiver does whatever added processing the user has told it to do - bass management, timing adjustments when speakers are not all the same distance from the sweet spot, and EQ to compensate for room issues. The AVR also applies any DSPs (digital signal processors) that the user has engaged. PLIIx, DTS Neo:6, and modes such as jazz club and stadium are all DSPs that modify the original PCM in some fashion. Your AVR display tells you the type of source it has received from the player and what DSPs you have engaged for that particular source.

ok :d

I've got the same amplifier but a different question

Is it possible to run 2 subwoofers off this amp?

[platinum]

O'right, O'right, I rewatched yesterday night "Streisand: Live in Concert 2006" but this time I set SurrBch to Auto (and also tried OFF position, too). Wow, the PLIIx is gone, disappeared magically
I stayed with Auto Surround in lieu of Pure Direct mode.

Thanks ALL of you
TCR Alliance, have a good day

- With these DSPs fashionned sources added, the final audio quality what I heard is worse, better or no valuable added value than the natural original lossless source?

I'm not sure what you are asking. DSPs modify the original PCM in some fashion. Whether you like the changes is a matter of personal taste.
