View Full Version : Dolby Pro Logic II vs. DTS Neo:6
01-09-2003, 02:03 PM
This is my first post here at this board :)~:-)~:smile:
well I just wonder when I should use DPL2 and when to use Neo:6
Or more like it, will Neo:6 work just as good as DPL2 when a movie on tv is broadcasted with dolby surround/dolby pro logic?
I wanna use Neo:6 because the extra back speaker, but if it is not meant to be used with tv broadcasts with dolby surround then I will just stick with the DPL2 (When IS it meant to use Neo:6 btw? :)~:-)~:smile: )
Please sort this out for me :)~:-)~:smile:

Welcome to AV Talk MrTwo :)~:-)~:smile:
Neo:6 is really just the DTS rival to DPLII, something they probably felt they had to offer rather than felt any great desire to offer.
I personally use DPLII for non 5.1/6.1 sources, sometimes engaging the two rear channels if it's a show that I think might benefit.
From reading plenty of forum posts on the subject before now, it would seem that the general consensus is that DPLII is the slightly better performer of the two in terms of more realistic steering.
That said, there's no harm in experimenting and simply using whichever flavour of processing you find best to your ears :nod:

As juboy said, it is just a matter of personal choice.
DPL2 is to Neo:6 as DD is to DTS. Just different companies trying to do basically the same thing. Some people prefer DD & some DTS.
I personnaly always use DPL2. I did try Neo:6 but prefered DPL2

Slightly OT, but I keep hearing Meridian owners saying just how great Logic 7 is. I'm not doubting it is I just wonder why the Denon/Pioneer/Yamaha's etc don't incorporate it into their own products. Is it a Meridian proprietry DSP (or whatever the correct terminology is)?
Also why is everyone so down on 5/7 channel stereo - it's excellent for non critical especially radio, IMO.

Lexicon Dazed, Lexicon.
Whilst you might hear a Meridian owner say how great Logic 7 is, they will then proceed to shout the roof off about Trifield, Music and SuperStereo processing.
Logic 7 is like Audio crack, you know it's bad, but it is so addictive. Properly setup it will make you think you're there.

Okey, thanks guys :thumbup:
So you are saying that Neo:6 "understands" the dolby surround/dolby pro logic sound that is embedded in the tv stereosound just as good as DPL2 does? and sends the right signals to each speaker..? :)~:-)~:smile:

Neo is what get's used when DTS ES is engaged. That's how DTS license their ES format.
DPL, DPL2 and Neo6 all understand the basic encoding of Dolby Surround. Anything that is the 100% identical in the stereo pair get's sent to the centre. Anything 100% in level, but 180 degrees out of phase goes to the rear. What's not the same is anything that doesn't fall into these neat categories. DPL doesn't do anything with them, just leaves them in the stereo pair. DPL2 and Neo6 use their own DSP trickery to create stereo surrounds, using complex relationships between phase and level.
So the basic stuff that get's deliberately encoded for Dolby Surround is there in both, it's what else get's added that's different.

well if i dont notice any difference in sound and surround quality then i will probably go for neo6 so i can use the center rear speaker..
big thanks to you again :)~:-)~:smile:

Ok then Mudge :bow: Lexicon it is. Lexicon and Meridian both filed in my brain as stuff I can't afford, or choose not to afford, priorities dear boy, priorities. Actually I'm kidding myself can't afford is correct
Still the question remains why don't the mid-end manufacturers purchase the rights to use Logic 7 in a similar way the must have to pay Dolby Labs and DTS or is it proprietry to Lexicon?

I believe Logic 7 is proprietary to Lexicon's parent company, Harman Specialty Group - Logic 7 in a simpler form can also be found on Harman-Kardon equipment. Trifield is not proprietary to Meridian, though - they license it from somebody else.

Nic, not sure if I'm right so don't take this the wrong way, but isn't Trifield proprietary to Meridian, and Ambisonics is licensed by them?
Why don't more manufacturers license the top end DSPs? If anything this has more to do with them having to pay huge licensing fees to the developers.
Writing a DSP mode that interprets phase and level information in a 2 channel mix and produces five (or more) different channels is not too hard. Writing one that sounds good, is a lot harder. :)~:-)~:smile: Just ask Yamaha, pioneers of the 1001 DSP modes that all do different things and nearly all sound awful.

Who are these guys, then?

You are quite right, Meridian license both Trifield and Ambisonics from third parties. I also found a Trifield mastering processor for creating multichannel mixes from stereo recordings.
