occasionally the so called flagship denon avc-x8500h gets Dolby truehd 7.1 confused with and reverts to Dolby digital 5.1 . something in the hdmi handshake with maybe the oled , projector to avr gets messed up and simple switch avr off wait few seconds and switch back on resolves the issue .

i had to be pushing some acoustical THX watts yesterday and don't usually run the 4k laser projector for myself . projector lamp 90 hrs used and is few years since got it and as max lamp of i think 30k hrs ? surely not . even lamp will be cheap for it now .

top gun 2 , Dolby atmos 15.12.2/6/8 , lucasfilm ltd THX sound system

312024023_10160119580980149_89250606795491723_n.jpg


Denon AVC-X8500H
heights used on top gun 2 is mostly only height 2 middle . disappointing . rarely briefly height 1 is used for few pointless seconds of missile .
there is some bad mixing sound continuity with some random overhead at opening titles for moment on music thought it was going to be great ? oh what let down .
some aircraft taxing on the aircraft carrier on screen then overhead ? made no sense since camera wasn't in a position or for the sound being overhead , just randomly mixers throwing sound up there . also air traffic voice controller is heard but made no sense since i can tell where camera is and voice would have to come from where bridge towr is ? and i see no high pylons for that to even happen ? just random sound mixing for atmos overhead . some scenes where plane takes off on the catapult ? a few brief pointless seconds .

not even by far the best atmos movie of 2021 . just an average atmos with little to go for it .
did it have any anti-phase in the overhead ? not that i can detect on my THX system .
i can still use the side surround ( below surround ) as my below surround is x4 zones of it . i rather play " baby driver " chapter 18 again lol .

i'm not in the habit of buying new movies anymore . i rarely buy new ones now at rate of maybe 1% for whole year now .


screen channels i use the five screen wide . occasional on-screen dialog panning or some of it was fixed to screen left screen right or faintly between left centre right centre .
the flare defence on the aircraft sounded neat in five screen , sort of wowed me .
the height 2 does have a few swirling phase effect .

i do have additional option to possible make height 1 2 3 better that would be with PLIIx using all its outputs as maybe rarely there be some anti-phase and the sound would be steering around channel to channel . it means fitting lot more speakers on the ceiling . but it is only option since no AVR/AVP will even offer any of that . got to add on to get some more surround going on .

there was colour banding noise on main menu ? strange and sort of bothered me ? was there any colour banding on the feature itself ? well i recall the steam on amzon where the " SR-72 darkstar " explodes in the sky and fades to black . on the disc i sort of was looking for it as it was bad on streaming .


was the darkstar scene any good ? i be honest . it was rubbish . worthy of headless panther and the cat litter box . i rather watch , " final approach " 1991 with SR-71 that has legit bass that is uncompressed on PCM Dolby Stereo . top gun 2 sounded compressed . it didn't seem to have real dynamic range , just sounded compressed and total hyped let down . not worth renting or buying and within a month , top gun 2 will be another 4k sat on the bookcase gathering dust until i play a scene from it again ?

x2 onkyo AVR with PLIIx and multi stereo mode function .

so i be expanding on the Dolby atmos or use for regular Dolby Stereo 4.2.4 or Dolby 5.1/7.1 dts and dts-es 6.1 mixes ?

present system at 15.12.2/6/8 . once installed the PLIIx to sort of upgrade over the x2 Dolby CP45 been using for matrix expansion of steering the panned/phantom sounds with newer like extra channel as served well . i think i like to expand it further now .

once finished it be around 21.12.2/6/8 . i can later expand it to 23.12.2/6/8 . i can even expand it further with few x3 more cheap onkyo avr PLIIx and additional matrix PL decoder connected to front L R as often in some discrete mixes there is additional centre phantom which would be better placed ( two ways of doing it ) mixed into an audio mixer with centre discrete and blended back into the centre channel or extra amp and speaker which i can't there no room behind the screen for full-ranger JBL cinema speakers so i have to blend it into centre .
so i can expand that to 24.12.2/6/8

i can even expand the extra surround channels on the PLIIx stereo surrounds and back stereo surrounds with additional expansion/enhancement from 24.12.2/6/8 to 24.22.2/6/8 .

apollo 13 imax or liemax version ? chopped up about 20 mins plus out of the movie as liemax cinemas 70mm can't hold over certain amount film on the cake platters . end credits looked sounded dreadful with solo horn trumpet being cut of the end credits .
some scenes had a bit more dynamic bass impact on the launch scene .
aspect ratio was more like looking at super35 open frame rather than masked for scope with anamorphic stretch for 35mm cinemas during its theatrical release .
the imax version , meh . prefer the theatrical release .

one onkyo avr fitted partly in kitchen amplifier rack . this will be for back surround project x eXpansion of the stereo back surrounds .
the other onkyo will be for side surrounds or the " original surrounds " project x eXpansion .

the Dolby CP45 i see what i can use them for later ? i not yet uninstalled them .

project x2.jpg

project x3.jpg
project x4.jpg


had to shuffle all the amps and SA10 , DCX to fit the onkyo avr in the rack barely fitted . had to remove the feet which reduced height by 1/2 " .
got to redo all the output cables on the DCX for powering the crown anmp as now the cables are too short . simple cheap three core shielded microphone cable .

i use real cinema seating . so how does that compare as this is ASR and its all measurable .
the fronts of the seats are fabric absorbed , hence less so reflective than most home cinema seats that are plastic or use some poor creature animal skin , shame . is going to be reflective .

i tested the backs of my cinemas seats and found them to be predictable reflective and easy to solve . also frequency response , hearing sound behind me is not problem i have exceptionally good horizontal to diagonal hearing behind me as i have trained myself . now then !

matt hooper take on jaws . it was a shark . you'd think the short echo sound is my room ? wrong . its the film mix of what is mixed in should only be the sound heard . my room is totally absorbed , floor carpeted , walls ceiling wedge titles so only the details are heard on the soundtrack . otherwise i be depressed hearing the room with reflections sounding like most typical home cinemas or even some few cinemas 1.5m/s i rather that be way less of under several m/s . i don't want hear high frequencies pinging off the walls and ceiling . only pings should be the speaker/s itself . its the same when listening with headphones .
