Axiom Home Page Forums General Discussion Home Theater My Atmos thread

My mistake, there has been alot of people upgrading recently i thought you had also added the VP180 at the same time.I understand what your saying, i had Denon 3311 and when i went to the XMC-1 it was whole new ballgame and that was before running Dirac. Hopefully your sub issue is that simple that would be nice,keep us posted.

Yeah hard to keep everyone in check around these parts, lol. I've had the 180 for 3-4 yrs now I think... Watching Sully tonight, based on a true story, good movie..

Can you watch a movie sans ATMOS using traditional true hd. I am still waiting for EMO to release their ATMOS upgrade, they run on a time zone all their own LOL. I also have a 5 Channel amp for my main 5 and also a 3 channel that used to run my front 3 ,not enough for atmos so im trying to sell it and then upgrade to another 4 or 6 channel. Much harder to do with the dollar the way it is plus owning a house. Ne way enjoy the movie .

Trying to understand the question. From what I can tell any prior surround format even pro logic can be accepted they a receiver capable of Atmos. If I watch a movie that shows Dolby 5.1 on the DVD case, the Anthem display will show Dolby 3/2 meaning 3 front and 2 surrounds, same with 7.1 showing 3/4 on the display. Tonight I watched Sully in Bluray and it showed ATMOS, so I am guessing the movie was decoded with ATMOS engineering.

Sorry , sometimes it sounds right in my head but not when other read it. I was hoping you could quantify the improvement the receiver made devoid of the ATMOS upgrade. IE playing back a 7.1 truehd movie without using any of the ATMOS intervention. Truehd is channel based while ATMOS is object based so it is my understanding that you can reauthor the audio with the receiver to take advantage of ATMOS even if the sound track is not ATMOS. Also do you feel you lost anything by going with M22's over the QS8's when watching standard dolby sound tracks.

I follow what you are saying now... I am not sure there is a way to turn ATMOS off/on but can look around in the settings. I can turn ARC off/on to compare room correction or not... I could turn off my ceiling speakers to see what that does. I will try to poke around the next few days...

So your saying that ATMOS is automatically applied even if the source material is not ATMOS enabled?

I don't think that you are understanding the term ATMOS. Think of it like a newer version of Dolby Digital.

My first HT reciever did dolby surround. Then I got an upgrade to Dolby Pro Logic. This went from 3 channel to 4 channel. Two totally different technologies, but based on a method of taking a 2 channel signal and figuring out how to fool our ears and brain into thinking we are getting 4 channels of sound. we now have Pro Logic II, IIx and IIz that take the 2 channel for 5, 7 and 9 channels.

Fast forward to the Dolby Digital era. There was a quantum jump from 2 discreet channel recording to now going digital and giving 5 + .1 low frequency sub. The development continued to give us DD EX 6.1 (5.1 discrete + matrix center rear sound using technology similar to Dolby Pro Logic). those were replaced by Dolby TrueHD that gave us 7.1 discreet channels.

ATMOS fits to the side of TrueHD. To quote from Wikipedia:



So an ATMOS receiver if given a non ATMOS track, it won't be doing anything to convert it to digital objects or anything funky like that.

What each receiver/pre-amp company does it up to them. They have the ability to do the Dolby Pro Logic like matrix conversion to drive all the speakers that are hooked up to their device. For example, Yamaha has their own Matrix 11,1 implementation that is not connected at all to Atmos. They use height speaker instead of overhead. Pioneer have their own maxtrix 7.1.4 that takes one side sound and matrix it with the other side to figure out what it thinks is overhead.

It is NOT ATMOS. It just sounds better to your ears as it makes sounds come from more directions like real life. It is like how Pro Logic sounded better than simple Dolby Suround.

All that said, a well setup 7.1 with speakers like the QS(x) speakers will send as much sound up and around to give the same effect as an GOOD install of a Matrix processed with 7.1.4 speakers. The QS speakers are effectively doing what the matrix sound process is doing in the receiver. Again, THIS IS NOT ATMOS.

Randy, I bought several GLS Audio XLR cables off Amazon based on the reviews there. I haven't used them yet, but they appear to be very good quality for the price...much better than I expected.

Another good option for the XLR cables is any guitar music shop E.G. Tom Lee or a Long and McQuade if you have one local they usually have them for less than 10 or 15 with a pro option.
