So just to add to the last previous posts, I’m listening to a Film4 flick on TV and this is what the BeoApp is telling me:-

So, crappy stereo 2.0, PCM coming in and the Theatre/True Image is doing its best to distribute the sound across all speakers. I’m guessing it’s trying to emulate 5.1.2 but there’s not enough info for any spacial sound distribution. The sound is weak to say the best on the surrounds.

Evening all - I had my Theatre installed yesterday, wall mounted and a separate lately wall mounted 77 LG G2. Looks pretty neat and tidy.    The rest of the setup comprises my BL50s (as front L/R) and newly added BL17s are surround/rears. Generally everything seems to be working fine, and starting from scratch it only really took me a few hours in the evening to get my head around the settings / app etc. The only issues I am having are :

• if I mute the volume (using the BR1), the tv/theatre will often unmute itself within a few seconds.
• elsewhere, I can lose sound completely (picture remains) when bringing up and then removing the LG menus (or even using a webOS app, and then coming out of it). The sound is restored by pressing the source button again on the BR1.  My dealer has the same issue in his store.
• the BR1 will, under the List button, show the active HDMI source - it shows this second in the List list, underneath Theatre.  However, the BR1 is showing the wrong name as the active HDMI source at times (the associated PUC functions are correct to the active HDMI source).

Elsewhere, most seems all good. Not sure if anyone else has similar (albeit these are small) issues.  

Following up, I also added a new Panasonic 820 UHD blu-ray player, connected to the Theatre. This evening I tried to play some of my current (and 1080P) discs with DTS as their main track (obviously these are not object based DTS)

I wanted to see what results I would get, given the Theatre does not list DTS as a compatible format.

For reference, the Panasonic 820 allows you, in its settings, to send Dolby as Bitstream, and DTS as PCM (i.e no need to switch back and forth)

My findings were a bit odd.

With the player set to Bitstream DTS to the Theatre, when I played a movie, the Theatre had both picture and sound. The B&O app showed the Input Signal as PCM 7.1, even though the layer was set to Bitstream (??)

Changing the player to send DTS as PCM - again, and more understandably, the app showed Input Signal as PCM 7.1.

So it seems as if whatever my player is set to send to the Theatre, the Theatre app is showing PCM 7.1.

More importantly though - caveat being I only did this test with 4 or 5 discs - is that while the Theatre is playing a (seemingly PCM'd) DTS track, the sound was not great.  Most noticeably, the vocals were pretty restrained and not easy to hear. But this weak performance was not just confined to vocals.

Using one of my BR discs with a main Dolby track - the sound was much better, and vocals were prominent and not issue.

Anyway, I will keep tinkering, but it's not clear thus far that playing my existing DTS discs will work with the Theatre.

Would be interested if others have tried and had any observations.

 

 

Ahh Great,

I am looking forward to see if you find the extra speakers worth it.

It is the setup I want to have, when I move. And yes the BL3 is now a very good and cheap option.

And I agree that the BL90 is enough bass, not to compare but I have the same with my BL5, the BL19 will not add anything.

Yea I'm not a fan of the 2.0 to surround upmix. Speech especially sounds tinny. I prefer to run 2.0 content in Direct mode. Either to the BL9 fronts, or just the Theatre alone.

 

Hi everyone,

A link to the Theatre's Technical Sound Guide v.1 is now available at

I hope that this may also help to clear up some of the confusion that I read in this thread... (particularly the comments about an Atmos input stream and the number of output channels, the difference between channels and objects within an Atmos stream, and the behaviours of True Image vs. Direct" vs. "Downmix" spatial processing modes.) IF, after reading the TGS, you don't think that the questions/confusion in the thread are addressed, please reach out here and I'll try to help - and update the TGS accordingly, where appropriate.

Of course, the TGS will go through version updates to reflect changes in future SW releases.

Cheers

Just out of curiosity

• what is your source for the 2.0 content?
• which Sound Mode are you using when it sounds tinny"?
• How are you doing the 2-in-2-out configuration? with a Sound Mode set to Direct in the spatial processing or by having created a 2-output Listening Position?

Thanks -g

CODEC – Dolby TrueHD (Atmos is an extension to DTHD)

This is not really true - it's kind of the opposite.

• Atmos is the method of packaging the audio channels and objects.
• TrueHD is an indication of the audio quality of those signals

This similar to saying 5.1-channel LPCM" or "2-channel MP3" where the first half tells you how many audio channels you have and the second half tells you the COmpression-DECompression (or CODEC) method that's used to encode those audio channels. Cheers -g

Hi everyone, A link to the Theatre’s Technical Sound Guide v.1 is now available at https://support.bang-olufsen.com/hc/en-us/articles/4955893911569 Thank you Geoff, great reading. Kind regards, Yann.  

Thanks Geoff,

I will also add the Technical Sound Guide link to the "sticky" thread that acts as a knowledge base for Theatre users. Grateful for your input as always.

Kind regards, Steve.
