The new Dolby Surround up mixer is better in everyday than previous iterations of Pro Logic. They ran out of letters with Pro Logic IIz and, I guess, decided against Pro Logic IIIa.
It will take 2.0 signals and "up mix" them just as before, BUT, it is now "object based." Without real atmos metadata, it decides which sounds get thrown around the room like a ball. When no height speakers are in use, it also uses an algorithm and makes sounds appear to come from above as best it can after "upmixing" the track provided virtual speakers are set to On with speaker assignments from 2.0 to 7.1.
Different receivers have different limitations when processing Dolby and DTS tracks to this day. Cross upmixing is limited between the two. With every manual available online for all new receivers, one can look up a model they may be interested in purchasing and see exactly what that receiver can do with any given codec. The charts can be confusing at times with asterisks and numbers popping up all over the place with one constantly looking to see what limitations those marks entail. Every imaginable mode applied to every imaginable codec is still not possible today but there are many more options than were possible just a few years ago.
Sadly, as new processes and codecs come along, some processes and settings are left behind and we have all purchased replacement models of varying devices and machines to find that one of our favorite features is gone. As for the new Onkyo models, I can only comment on the new TX-NR6050. I've said a bit and have more to say about it as I've been comparing it to the Denon AVR-S760H and Yamaha RX-V6A in another thread that will be linked at the bottom of this post. . The Onkyo is a slightly altered TX-NR6100 that was meant to update my TX-NR696. There are new features I love about it while I also mourn the loss of a few others.
No, the TX-NR6050 does not have the older "Sound Mode Preset" that many liked in older models. It simply applies the mode last used for the input IF the audio source codec has not changed since last used. There can be frustrating taps to the Movie or Music sound mode buttons when audio codecs change and the mode is no longer the preferred one for the job. Volume levels can be applied for each input source. You can set the level or simply select "Last." Source specific settings can be made for any number of things BUT many of those settings can ONLY be made using the receiver's web setup feature. I still haven't gone through all of them but there are quite a few of them concerning HDMI 2.1 video features.
Dolby 2.0 tracks are such a mixed bag. How well it is processed is all over the place. But, yes, the Dolby Surround and DTS Neural/Virtual:X up mixers can get the dialogue centered BUT Dolby processing can suffer from bleed while DTS does better with a lousy 2.0 track. This has been the case using several different receivers and Dolby 2.0 tracks. Results can and will vary depending on the content and devices used in the setup. Everybody is going to have a slightly different experience.
"You long winded, self important motherf#%ker! "Just tell us how it handles DTS HD Master Audio 2.0!" Ok, ok, for crying' Pete! Concerning DTS HD Master Audio 2.0 tracks using the TX-NR6050, things get interesting. Take "The Greatest Showman." The UHD Blu-ray Disc contains a Dolby TrueHD/Atmos(7.1 lossless core + metadata). It also contains a DTS HD Master Audio 2.0 track. Dolby Surround can be applied to the DTS 2.0 track and all sounds good with dialogue coming from the center channel. Apply DTS Neural:X and things are still very good. BUT, apply DTS Virtual:X to the DTS track in a setup without height speakers and things get much better still. I f#%kin' love it! I'll never play the Dolby track or use the Dolby Surround up mixer ever again on that disc. The DTS 2.0 track using DTS Virtual:X presentation is that good. "Are you out of your f#%kin" mind?!" Nope, just like to get folks' goat is all.
I'll also never listen to the atmos track on "Ready Player One" from now on. DTS Virtual:X applied to the DTS HD Master Audio 5.1 track sounds much better to me than the Atmos track. "WTF!
" Come on guys, I didn't say it IS better, I simply said it sounded better to me on my setup.
Ok, so one last example. I decided to pop in "Snakes On A Plane" DVD. S#%&ty pic on that one and it includes a s#%&ty Dolby 2.0 track. I select it. I apply Dolby Surround to track. It bled like a stuck pig.
I applied DTS Virtual:X processing to the track and there was no bleed at all.
I am using HDMI-CEC. I hit the power button on the TV remote control. Everything turns Off. I wait and then hit the play button on the UBP-X800 remote control. Everything turns back on and the movie starts back up right where it left off and DTS Virtual:X is still doing the processing of the audio. Joy! It's a Christmas Miracle!
"Hey, Mr. Know-it-all, you forgot to mention room correction." Oh, f#%k that noise!
