if not mistaken, the emulated atmos from true-hd is called "dolby surround"

I never bother on this, Dolby surround, DTS or THX.
For me, getting the first 5.1 channel right will be more important.
If a person can do this right in the first place, adding another pair(s) of speakers won't give good effect on HT enjoyment.

actually is "dolby surround up-mixing".i heard a lot of people saying its doing a very good job up mixing any source to atmos atmosphere.so basically we don't have to rely on dolby atmos title because of this up-mixing.and some of them say its better than dts neo x,dsx and dolby prologic..

AFAIK,

Dolby Atmos codecs in a Bd is a dedicated channel - kinda like 7.1 but for de overhead speakers as well.. so technically - it should sound a lot more discrete [better] than de DSP's from an avr..
But frm my experience, going from 5 to 7 is not tat life-changing so l'd take atmos wif a large ladling of salt..

My 2 cts la .. othrs will differ
D

I agree that it might change much unless you have sensitive ears to hear the difference

From conventional 5.1 setup, by adding another pair of speakers, be it next to rear speakers, let them fire upwards, install it from ceiling firing downward also will have effect.

Any sifu can please explain the sub woofer setting the hz lower or higher make any big different.tq

are you asking bass lfe crossover? 80hz is cinema and thx standard

lower hz will make subwoofer give good impact but your main speaker must have adequete cone size. usually 6.5" or else mid bass missing.
higher hz will blend better with small speaker that lack of mid bass, but the subwoofer may localized one side and resonance boom within room.

In theory is you need to know the lowest frequency your speaker can go and what is the highest frequency your sub can go. The middle point of the speaker and sub is your cross over. If you set it wrong then certain frequency will go missing or hear it.

Thanks bro. that mean setting to 80hz is standard unless as u stated lower hz, have to had bigger size driver.Is it the same for crossover setting for speaker.

But as i can see the avr have individual setting for front, center, surround n sub. So how to get the best hz setting for individual but my sub got setting button for hz too.

80hz is guide line not necessary to follow exactly.
actually not that simple, need to adjust together with channel level.

give u one example, my main spkr use dual 5.5" floorstanding. center and surround are 4" mini bookshelf type. a 10" subwoofer set to bypass all control to avr.

auto calibration give front 60hz, tilt up center 80hz, surround at rear corner 80hz. bass lfe crossover inside receiver is 120hz, not adjusted by auto calibration.
while many foreign forums says leave 120hz as is, to contain full signal from 5.1 movies. the result is shaking boom.
decrease sw channel level helps in movie but music become lean bass no kick.

so i experiment adjusting lfe crossover to 110, 100, 90, 80, 60, 40 by ear using rock music. 80hz was the best until i add acoustic foam, 90hz become more natural to blend in room.
increase sw channel level to match with main spkr.

for front spkr crossover, i tried 80hz voice is over energetic (not realistic). of course it depends on your taste
those frequency that peak in between front 60hz and sw 90hz has been taken care by acoustic foam.

natural roll off

Another question for sub, there is a setting for normal n reverse phase, normally u guys set to normal or reverse phase.tq

I use the default reverse.

I set reverse phase on the sub side n avr normal but when i set avr to to reverse n sub side also reverse no sound from sub. Anything wrong or my setting is incorrect

The first setting should be the right setting.

You don't try to use YPAO first before manually tune? Tune the sub correctly than use YPAO to detect the setting.

Most (if not all) of the current audio mixes for DVD or bluray is based on either Dolby Digital 5.1 or DTS (for Digital Theater Sound) lossy (or compressed mixed), and for bluray mostly DTS-HD or Dolby TrueHD

Unless all of your movie is encoded in PCM 5.1 or LPCM 5.1, you are using the surround audio setup, and THX is not an audio standard.

I already following government's advise on cutting cost of living.
So no DVD5/9, just download
Are those encoded in PCM/LPCM like you say? Nobody will knows
This is like chasing shadow game, getting something that we don't require
