Just wanted to point out for those planning on going through all the steps/costs for the DTS implementation, you should refer to Chapter 18 (Appendix A) in the v2.00 User Manual to see the complete set of available "Listening Rooms Loudspeaker Configurations" which are available for the three operating modes:
18.1 - Dolby Atmos (16ch, up to 9.1.6)
18.2 - Dolby Atmos (24ch, up to 16.1.4)
18.3 - DTS:X (12ch, up to 9.1.2/9.2.2)
18.4 - PCM (16ch, up to 9.1.6 or any custom configuration using up to 16 speakers)
Also, realizing that no matter what PRIR/HPEQ/room/source you create for your presets (for quick and convenient selection in most normal listening situations), obviously you can always temporarily change anything you want starting from a preset in order to meet the special specific needs of any unique situation.
So in contemplating whether or not to create DTS-related presets that added artificial DTS surround objects (i.e. when listening to 5.1/7.1 non-DTS:X movies mastered with either DTS Digital Surround, DTS-HD or DTS-HD MA), I decided that I did NOT want to add artificial ear-level or overhead speakers if the original soundtrack didn't have them present. So for maximum usage benefit and convenience (and "original" sound) from having a preset exist at all I decided to create my own set-of-3 DTS-based presets as follows:
(10) 5.1 (based on DTS room #8, with 5.1 speakers taken from my AIX 5.1 PRIR) to handle the old 5.1 DTS Digital Surround (e.g. on the Eagles "Hell Freezes Over") as well as newer 5.1 DTS-HD Theatrical (e.g. on "Ex Machina", if you choose not to play DTS:X)
which is handled as follows:
(11) 7.1 (based on DTS room #26, with 7.1 speakers taken from my AIX 7.1 PRIR) to handle the old 7.1 DTS-HD and DTS-HD MA (e.g. on "Les Miserables"):
which is handled as follows:
(12) 7.1.4h (based on DTS room #41, with 7.1 speakers taken from my AIX 7.1 PRIR and Lh/Rh and Lhs/Rhs taken from the BBC room) to handle the new DTS:X (which I believe is fundamentally 7.1 DTS-HD MA at ear-level):
which is handled as follows:
NOTES:
(1) Although I do have the 24-channel APM/HDMI hardware upgrade installed, I'm still configured for 16-channels. If/when I ever have an opportunity to get a new personal PRIR created in a genuine Atmos-enabled studio that has more than 16 speakers I will adjust things accordingly.
(2) DTS:X always presents as "Immersive" for the A16 Decode value, rather than a specific speaker arrangment as with Dolby Atmos. Output "object" sound is heard through whatever speakers are configured in the A16 Listen room setup.
(3) Since my AIX 7.1 PRIR represented actual ear-level speakers, I decided to add four "virtual height" speakers (i.e. 7.1.4h) rather than choose 9.1.2h which would have added two virtual ear-level virtual speakers along with two virtual height speakers. I want what I believe is the underlying 7.1 DTS-HD MA delivered only through my 7.1 AIX PRIR real speakers, virtualizing only the four object speakers.
(4) I decided to use "height" speakers (i.e. 7.1.4h) rather than "top" speakers (i.e. 7.1.4t) as my additional DTS:X-fabricated virtual object speakers simply because I thought it might sound "more immersive" (I don't claim this is "objectively valid" reasoning).
