whats the deal with 9.2??

[Joeteck]

Ok, a few receivers can do 9.2, 11.2...etc... does the amp make the presence audio, or is that part of the Blue ray DVD?

um none that I know of. Sounds gimmicky to me.

9.2 might be nice, but the fronts are still the most important.

 

[Joeteck]

Yeah, it adds another two front speakers higher.. Don't understand it. MAybe someone can shed some light on it who has set it up... I hope its not gimmicky, its on their RX-Z11 flagship receiver too..

Really. Now that's a great idea.

Time for an upgrade?

It's a gimmick. The new ProLogic II simulates 9.2 with the last two channels matrixed from the front mains. These are not dedicated channels. Much like when you derive 7.1 sound from 5.1 sources. Yes it's nice but definatly not needed and in some cases the sound is worse than just using the dedicated 5.1 I assume some speaker company go together with ProLogic and said, "hey, we'll give you a percentage of all speakers sold, if you include this new codec in your recievers. Now tons of uninformed buyers will shell out money on simulated 9.2 from Blurays 7.1 movies. Let's not forget that 1 out of every 10 Blurays is still in 5.1 and not 7.1 I an't imagine the matrixing going on listening to 9.2 from a 5.1 or stereo source.

It reminds me of this nimrod I know who lives overseas who matrixes all his speakers in this "Whole Overhead sound" thing, where he is running 12.1 or some hooey like that from a 5.1 source, by downmixing his dedicated channels via prologic decoders.

It'll be a long time before I even move past 5.1 or maybe 5.2, but two subs are better than one

7.1 requires a decent sized room to make it worth wild and 9.2 with "height" speakers sounds like it might be worth wild if your room was 12 or 15 feet high. Next to that I think it would just be more of an annoyance.

lol If you have good enough mains you won't need 9.2

Unless you place the lower speakers closer to the floor I guess.....

 

[jostenmeat]

How "good" will depend on the quality of the DSP/algorithm. I personally would have decent hopes, unlike some others.

To me, it's not so much that it's gimmicky, but that it's a lot of time and money for AV effects that will be sparse. Video, you always see. Dialogue, you almost always hear. But, for the rarer movie with a lot of surround effects, you have to buy more speakers, get more amp, run more wire, get some mounts, perhaps ugly up the room . . . I find myself asking if the implementation would be worth it, more than I question how good the DSP might work. My thoughts anyways.

My understanding is the 9.2 is supposed to "lift" the center dialog up if it is too low. In the end, it sounds like a gimmick to me.. How about just angling the center channel a little? I think you can buy some black felt at Home Depot for about .25, angle the Center channel up and Voila... You don't need 9.2..

Ok, I just saved a bunch of people a lot of money...

9.2, 11.2, unless you have a movie theater in your house, why on earth would you need this? Good speakers are supposed to create a sound field, right? Do you really need to have 9 or 11 speakers to do this? I'm on the fence about 7.1 and I have a pretty large room to begin with. I've never felt the need.

I say, put your money toward better speakers if you feel something is lacking, as opposed to this gear with these gimmicky 9.2, etc. surround modes. But that's just my opinion...

The 9.2 sounds like a Yamaha presence speaker thing.

My receiver has 7 channels of amplification and you can set it up as 7.1 or 5.1 plus two front presence channels. It sounds like the receiver has 9 channels of amplification with the standard being 7.1 and the option to add two up front presence channels.

One of the Yamaha higher end receivers has 11.2 which is probably 7.2 plus two presence channels up front and two in the back.

I have my setup 5.1 plus two presence channels up front, mostly because I don't have a room layout to support 7.1. I figured I had two extra amplifier channels going to waste so I might as well try out the presence channels. There are mixed reports as to whether the presence channels are a positive or negative addition to the sound. I tend to experiment with them on movies more than music. For music I pretty much stick to stereo or direct modes without any DSP alteration.

There are more threads on presence channels on the AVS Forum below:

There are also probably threads in the Audioholics forum but my search came up with this result.

Have you thought about bi-amping your front speakers with the extra 2 channels, rather than using those amps for the presence speakers? The bi-amping will give you much better sound quality, that is if you have speakers that are bi-ampible.

One day soon, we'll see a receiver that will do 13.3.

And then I'll just have a good laugh again.

I don't think one needs felt. Just get a PJ. And you can usually put the speakers right at ear level and still watch comfortably.

Though some prefer to sit at screen height.

It just strange that they keep adding speakers to receivers when there are only 5.1 and 7.1 audio. Just strange to me... So I guess anything higher than this would be matrix...

 

[Hipnotic4]

lol like i said in another post..how many surround sound modes does one reallllly even use? More doesnt equal better..

For the newbeez, stick with 5.1 or 5.2

I'm hardly a noob. A noob to this sight, yes. Been doing HT for may years. Just budget systems. No need to spend be bucks to get what works..

Agreed. Aside from the Center Channel locking dialogue to the screen when you sit off axis, one doesn't need more than 4.1 or 4.2. with good imaging speakers.

all these other modes are just marketing hype for electronic companies to get you to upgrade!!!

You dont need to spend "big bucks" to get great sound quality. Especially with the internet..

Dont take offense to the noob thing..i should of said, If your new to this hobby, keep it simple..

 

[Highbar]

I can't wait for 10.5 or maybe 14.7 Come on Height channels all around with subs at every spot Even Mike wouldn't complain about that
