So Jeremy, are you really targeting a gamma of 1.0? Or are you after something like 2.2? Or a more reference film-like gamma like 2.5 particularly with the JVC 4k unit that has the CR to support it better?

If Jeffrey says he has 8.8 he is referring to output channels, THIS IS THE CORRECT NOMENCLATURE FOR IT even in Dolby Labs 22.2 experimental system.

Bull$hit Peter ,you or I can call it anything we want but if the source output has only one discrete channel then irrespective of the EQ ,software, or voodoo it is .1. Sorry ,I didn't make that up it is simply what's so.

I agree with you to a point Art, but it isn't so clear-cut IMO. How does one go about describing 5.1 over a 7.1 array via PLIIx or THX Ultra2? It's not discrete 7.1, but it isn't fair to describe that as just 5.1 either. How does one describe DD EX? It isn't 5.1. It isn't discrete 6.1. It's matrixed 6.1, do you call it something other than 6.1 in a passing description? The source is delivering more than 5.1 channels of audio, yet the discrete channels is only 5.1. What about DTS-ES discrete? That isn't quite fully discrete 6.1 either. I just think that the numerical descriptions aren't as clear-cut as you make them out to be, and if they used in a way where they only describe discrete source channels, then they aren't really the most useful either since such a descriptor is incapable of distinguishing between a 5.1 mix and an EX "6.1" source, or between a stereo source and a surround-encoded source.

You are hard headed as a Spanish bull in mating season. When you get a 2 channel signal in directv are you watching 2 in your system or 7.1? You consider your system a 7.1 right?

I am telling you that Roger Dressler reviewed my plans for a steered 12 channel system and said "this is exactly what we do in our 22.2 channel system in the large laboratory room". Roger Dressler head of research at Dolby.

My screenshot of the tact audio shows INPUT CHANNELS and OUTPUT CHANNELS, you are saying that input channels is what counts, fine but how do you discuss system employing more channels of output, either with just low pass information or the more complex ambiance extraction steered matrixes, or the even more complex height extraction matrixes?

We that work with such complex signal manipulations DEMAND THE RIGHT TO USE NUMBER OF OUTPUT CHANNELS as the channel designation, I am willing to compromise with a more descriptive nomenclature like I/O 7.1/10.2 but I am sure not going to let some overworked orthodontist telling me how to run my business because we need to communicate what the system is doing and 7.1 does not cut it.

Can't you Relax? Come down to Prometheus and have a Pina Colada by the pool.

No no I'm not disagreeing with this but at the same time there simply isn't any real convention. It is true however that the matrixed 6.1 is still by convention (and generally it is understood what one is getting) while the things in this thread get into some pretty unbelievable almost voodoo like hyperbole . Personally ,I'm particularly skeptical regarding the use of .8 designation with a single subwoofer channel.

If you're interested in the AIR25, you should check out the Munro series of professional monitors (Dynaudio drivers).

So are you guys saying that there is sufficient discrete information extracted from a single subwoofer channel at say 80 to 20Hz that warrants one calling the designation .1 now .8 ? I mean ,why not .27 ? And even if so could anyone tell it was occurring in a film sound track.

Interesting ,where did this designation come from and why isn't it designated separately from the primary channel rather within it ?

You should ask someone at Dolby, but the convention is used in pro gear, and at EHX that is exactly what Ps audio and Thiel did each speaker had it's own sub, the logic behind it is that home speakers seldom go down to 15hz where there is signal, so they call each of those subs a .1

In addition if you take the 4 surround signals and low pass them you can actually hear a Rear Sub that explodes at different times than the front subs and the .1 do.

The tact processor has a whole screen dedicated to multiple subs something called diversity subs that accounts for the position of all the subs in such a .3-5-8 config.

In helene where we had the rotary sub I thought the correct denomination was 7.1.1

I think that the ".1" designation originally implied that the sub channel had 1/10 the bandwidth of the full L-R channels.
