hehehehehe in lowyat oso got wat....

for music...sealed sub...i like....

come come come.....mau home demo???

First, go to the ATM and then go to listen to his live demo and become even more convinced. Next... the transaction. And off you go with the SB2000s. 

I already have 2 now, I buy the 2 from you I need to scratch head to see where to put it. Let me plan a bit first.
Stop poison!

not familiar with yamaha avr. perhaps is repeating side surround or just ear illusion.
auro may put additional codec for unsupported receiver.
otherwise ppl buy disc cannot play sound.

AURO-3D and DTS

You did not give any detailed info of your "DTS Demos contains Auro3D tracks". Bluray? MKV file? MP4 file? Not enough info for all your questions so I can only make educated guesses.

Not possible for Auro-3D to be encoded as other formats such as DTS.

DTS from DTS, Inc company.
Dolby Digital from Dolby Laboratories, Inc company.
Auro-3D from Auro Technologies company (Belgium)

Auro-3D recognized as DTS? Really?

Auro can change its own Auro-3D to be recognized as PCM or maybe Auro-2D. But... Auro Tech will have to PAY DTS, Inc licensing fees to include DTS into Auro-3D to allow it to be encoded and "recognized" as DTS. Do you think Auro Tech company will do that? I really do NOT believe Auro Tech will do it !

Same situation for Dolby Digital audio. Do you think Dolby Laboratories will allow its own Dolby True-HD to be encoded and recognized as DTS? NO... its impossible!

If you are playing your "DTS Demos" from a bluray disc, there should be bluray menu that allows you to select either Auro-3D or DTS. So... when you believed that the Auro-3D track was being recognized as DTS, then I suspect your demos are video files (MKV?). If MKV video files, then your "DTS Demos" should have TWO audio tracks... Auro-3D and DTS. If its a DTS DEMO bluray disc released by DTS Inc, I can be 100% percent certain that they will NOT include any Dolby or Auro-3D track inside... so this disc must be a compilation DEMO (not DTS Demo) disc from other companies (not from DTS, Dolby and Auro companies)

When you use any player such as Kodi or others that can "Bitstream", it means the source audio is sent directly out with any decoding to the HT Pre-Amp/AVR. As long as the player can bitstream out the audio type (such DTS, Dolby, Auro-3D), it means the player can support sending raw audio out without decoding. When bitstream happens, its your AVR that received and did the decoding of the audio source. If the player don't support Auro-3D bitstream out, there will be NO sound eventhough the AVR support Auro-3D!

Example, my Oppo 105D bd player support bitstreaming MKV files to my HT Pre-Amp. Due to a bug in its firmware, Dolby True-HD in the MKV file is "bitstream" out as PCM. The latest version BDP10X-83-0715 released in August 2016 restored the ability to bitstream Dolby True-HD out from MKV files.

I assume your HT AVR AND your player (or Kodi) don't support bitstreaming Auro-3D out so what actually comes out depends on your player firmware (or computer plug-in) too. If your player don't support Auro-3D, by right it should "bitstream out" as PCM audio, not DTS. Did you find any info about your player which says that it converts Auro-3D to DTS?

When a MKV file contains both Auro-3D and DTS audio tracks inside, the "default track" can be set to DTS track by the muxing software so the player will auto play DTS, not Auro-3D. That may be why your AVR shows DTS which you assume "Auro-3D recognized as DTS" which is actually playing just the DTS track inside.



Kodi is a open source (GPL) XMBC software media center for the pc. I am not familiar on Kodi. Does it need to have the correct plugin to support Auro-3D bitstreaming? If Kodi don't support bitstream Auro-3D, I think Kodi will NOT convert Auro-3D to DTS (any conversion is actually NOT bitstreaming). IF Kodi support Auro-3D, then DTS will not appear.

If your HT AVR don't support Auro-3D and when such audio is received, then should be no sound. Yes, its possible for the AVR to receive Auro-3D and then convert to DTS but I don't know whether any HT Pre-Amp/AVR can convert Auro-3D to DTS loh. Mmm... so far I have not seen it. Yes, my HT Pre-Amp CAN change DTS-HD Master Audio/Dolby True-HD to emulate/convert to Auro-2D and is NOT the actual audio track inside the video file itself.



Original 5.1 Audio but Yamaha AVR showing 7.1 Audio

I have many years ago owned Yamaha RX-V1900 and Aventage RX-A3020 previously. If you use "Pure Direct", your amp will bypass all its own "sound modes" (such as Concert Hall) and tweaks to preserve the audio as near as original so it will not change 5.1 audio to 7.1 audio. If an audio is bitstreamed to your AVR, the audio is untouched so your player won't change 5.1 to 7.1. When you set your Yamaha to "Pure Direct", your Yamaha will also NOT change 5.1 to 7.1.

An AVR can be set to identify 7.1 as 5.1 by ignoring 2 channels BUT when the audio signal is just 5.1, your AVR can "increase" it to 7.1 by setting to "Multi CH Stereo" so your AVR will show 7.1 on its display panel. What this happens is that your AVR is taking the original 5.1 audio and changing it by select only 2 channels from the Left And Right Front channels and resends it out to the other speakers so the original Centre and all the Surround channels are ignored.

For example, I have 5.1.2 speakers and my HT Pre-Amp is also set the same way. When I play a CD, my HT Pre-Amp will only display 2 channels nut when I pressed my remote Green button, I can change it to "Multi CH Stereo" sound mode and all the 5.1.2 channels will be displayed. When I changed to Pure Direct, the 2 channels will be shown again.



I believe that you have already tried changing the AVR to "Pure Direct" so the original 5.1 will be used, no longer using any sound modes anymore. IF still appear as 7.1... then I suspect that your Kodi player have already changed the original 5.1 audio and sent out to your AVR as 7.1 so check the player that it is not changing anything. When Kodi player is bitstreaming, it will NOT "convert" 5.1 to 7.1

I didn't know that the "expand surround" is locked to "enabled" for the current crop of Yamahas as I no longer have any Yamaha now.

Yes, I do agree that pure direct is not a good suggestion to use. I also don't use Pure Direct for my Pre-Amp too (except for my external DAC input and turntable). Your clarification on this will help people who didn't know and may have misunderstood my suggestion of using Pure Direct.

I believe you already know why I suggested Pure Direct so my following recap is NOT directed at you. Teop's  question or rather "problem" was that his Yamaha was showing 7.1 audio on its display panel indicating 7.1 eventhough (according to him) the source audio was actually 5.1.

My primary reason to suggest Pure Direct was to ensure as far as possible that his Yamaha did NOT do any alteration or changes to the input source audio. So... using Pure Direct as a method of elimination of possible causes that "changed" the audio to 7.1 channels will at least tell me that his Yamaha was NOT the culprit.

After testing with Yamaha on Pure Direct and IF 7.1 still remained then it will indicate to me that the audio was already 7.1 when received so I can assume by pointing my finger to other possible causes... as explained in my earlier reply.

Hehe.. its never easy to pinpoint the reason for the change from 5.1 to 7.1 channels. For Teop's situation, its just like giving directions by phone to a blind person who don't actually know where he/she is.

Regards.

Your answer with "Let me plan a bit first" already tells me that you are already poisoned, in the process of figuring out a strategy and merely waiting for the right moment to pounce on it.

Remember... the early bird catches the worm! I think you will regret it when someone else took it away from you... so near yet so far, hehehe.

Mmm... is it possible to stack one sub above another?

Ben sifu....one unit almost sold....but its unit #2.....unit#1 still available

SSJBen 3 subs is better than 2....

2 in front and 1 for the rear....sibeh sui....the ambiance and feel is way different!

its not about loudness.....but the airiness and realism feel is hell out of this world

i've listened to such setup....man...even for music...the elevation is totally different

unfortunately I don't hv the budget right now...if not i would have kept my sb2000 and play something different in the setup....

put the 2 sb2000 to my rear part of the room.....LPF to 50Hz.....let it play the very low subtle frequency....or perhaps maybe try out of phase setting

I thought so at first, but double checked by sticking my ears to the back speakers.
The Auro track is coded in DTS just as the instruction on the video
The 'Demo Disc' is BluRay ISO and it is suppose to be from DTS but I can't confirm that. The name of the disc is 'DTS Bluray Music Demo 14', could be a 3rd party compilation for all I know. The track is actually encoded in DTS just like the instructions says in the video.

Even here http://www.demo-world.eu/download-2d-trail...ation_video.jpg provided 2 tracks, Auro/DTS. Not sure if it is still in the original form. Guess it is produced using the Auro processes but encoded in DTS (logically possible since in the end it is just sound output to speakers). Granted you will not get the full effect since I have no height level speakers.

As for the 5.1 -> 7.1, I did confirm that Kodi is bitstreaming in 5.1 as my Yamaha input page shows 5.1 but the output speakers shows all 7.1 is active. I further confirm this by placing my ears to the speakers. The strange thing is that in Straight mode, I would assumed that it would output as 5.1, same as the source. This should be the closest mode that still have PEQ. But then even in PureDirect, output is still 7.1. Guessed it is really locked or it is a firmware bug...
Ya you are right about PureDirect being not a good alternative and I did understand that it is really for testing purposes. But if Yamaha did actually lock the 'expand surround', even in PureDirect mode, I would definitely not be happy as what PureDirect is suppose to do. Can anyone confirm that there is no settings for this?

Since we are on PureDirect, for stereo sources it would still have some use, right?

Thanks for all you guys for the input. Cheers.

I just spent quite a bit on the pair of Ascend Sierra 2 towers and horizon center... haha. Remaining budget tied up for a new display too, so not sure where I'm gonna squeeze out for another sub.
I know bro. 3 is better than 2, and 4 is better than 3. Budget quite tight now and your deal is very tempting. But on the hindsight, I'm also waiting for the SB16U. I'll let you know!

No, the "expand surround" setting cannot be changed anymore. Again, all DTS tracks be it 5.1 in DTS-MA, DTS, or even DTS:X (where in it would be downconverted into 7.1) will be played at 7.1 if you have 7 channels connected and enabled on your receiver. It's been a "complaint" for many years now. Yamaha has not done anything to address this for whatever reasons and don't expect them to either in the future.

"Straight" is not straight for Yamaha. Straight simply means the receiver does not employ any DSPs or upmixers.

It depends. Some rooms really just can't do PureDirect because of too many issues within the room itself. People can harp about all the "turn off all the digital stuff! let is sound pureeeee!", really what matters is what sounds best to your ears at the end of the day.

Where did you get your Sierra 2? I love ascend acoustics speakers.

Buy online directly from their website. Needed to exchange a few emails and a single call to get the delivery plan proper though.

I've only had time set it up yesterday though, but got it 2 weeks ago. Hopefully can do some proper listening over this weekend.
