Dolby Surround & DTS Neural:X "Upmixers" on New Denon X2800 in a 5.1 System

If a DTS/DTS-HD 2.0 96/24 disc is played, DTS Neural:X is not a selectable sound mode. A DTS 5.1/7.1/X 96/24 disc would also be locked out of the Neural:X sound mode. I'm not sure what is going on with those two discs exactly and I do not have them myself or a Denon receiver at the moment to try and replicate the issue. My Onkyo does not have a DTS 96/24 limitation and still has multiple sound modes for all DTS signals while most DTS modes have been dropped from newer Denon and Onkyo models for just DTS or DTS-HD with Denon having up mixer limitations for DTS 96/24 signals.

Well, when I played Christmas Vacation, with a 2.0 Master Audio track (stereo), the X2800 read "DTSHD + Neural:X" -- are you saying if this disc was sampled at 96/24 the upmixer DEFINITELY isn't being applied? Because when I played the film, the audio was placed properly for a stereo track -- dialogue was in the center and some ambient stuff was spread all around.

It's not a 96/24 disc but a DTS HD MA 2.0 48/24 disc. Press the info button on the remote controller. What is the Signal info? What is the Sound(mode) info? Which of the Signal channel boxes are lit up? The Sound(mode) is supposed to display DTS Neural:X for DTS HD MA 2.0 48/24 tracks but if it is displaying DTS-HD + Neural:X as if it was a multichannel track it is no big deal. The up mixer is working properly.

I understand that it is "no big deal" because the track was steered properly -- but I wanted to know WHY it happened in case there was some kind of DISPLAY malfunction. There are others I have spoken to who claim they NEVER see the upmixer illuminate by itself when it's being used -- in other words, the front of the AVR reads "DTHD + DSurr" or "DTSHD + Neural:X" EVERY TIME a track is played that is using the upmixer for that particular signal. So, their AVRs NEVER show just "Dolby Surr" or "DTS Neural:X" by itself on the front. MY unit DOES show this on most content activating the upmixers, so I thought something was wrong.

Going back to the SIGNAL conversation -- I didn't press the info button when watching this disc, but I can. I'm not too familiar with sampling frequencies and the technicalities of the disc mastering, so if you could be a little patient with me with regard to this, I'd appreciate it; can you explain why the Christmas Vacation Blu-ray is a 48/24 disc and how this would affect the way the AVR shows the decoding?

There is more than one version of this movie on blu-ray. Your particular disc has a DTS-HD MA 2.0 48/24 track. I can’t find any information about version of this movie having a DTS 96/24 track. New Denon models have up mixer restrictions for DTS/DTS-HD 96/24 2.0/5.1 tracks but that will not be an issue here.

“So, their AVRs NEVER show just "Dolby Surr" or "DTS Neural:X" by itself on the front. MY unit DOES show this on most content activating the upmixers, so I thought something was wrong.” Your unit should display “DTS Neural:X”when playing a DTS/DTS-HD 2.0 48/24 track because it defaults to the DTS up mixer. It should display “DTS/DTS-HD + Neural:X” when playing DTS/DTS-HD 5.1/7.1 48/24 tracks as that is the default for DTS multichannel tracks.

If the receiver is behaving in a way contrary to the way it should be behaving according to Denon’s manual, contact Denon for help. Before doing so, study the manual. You may find it is doing exactly what it is supposed to be doing regarding a given signal.
