6.1 og THX....?


Anbefalte innlegg

Haisann...

har to ting jeg lurer litt på: THX! hva er det? er det bare en standard for å vise at det er sjekele god lyd? hva er forskjellen på THX og de andre "standard" merkene der ute?

 

Og hvordan fungerer egentlig 6.1 lyd? 5.1 er jo greit, da er det 2 front, 2 bak, en senter og en sub. men når du har 6!?! finnes det dvd'er osv, som har 6.1 lydformat? åssn funker det?

 

håper noen gidder å forklare!

Ja.... THX er bare en standart som er satt for at lyden skal bli så og så god.

 

Når du har 6.1 har du en center bak i tilleg!

 

7.1 er med 2 centere framme i tillet til fronthøytalerne.

 

Har ikke sett noen filmer med 6.1 eller 7.1 men jeg har heller ikke sjekket...

 

Mvh.

Nå har jeg bare 5.1 selv, men er ganske sikker på at 7.1 er med fire satelitter bak, 1 center og to fronter.

Ja, men du glemte subwooferen. :D

 

THX er litt mer en det som er sagt tidligere her.

Her er noe jeg stjal fra en på avforums.com

"Here are a few facts regarding THX.

 

1982: After extensive research, Lucasfilm engineers develop the ideal environment for mixing rooms, from which the THX system is developed. First THX mixing room opens at Lucasfilm.

 

And Jumping forward a few years.

 

1994: THX Audio System demonstrates a 5.1 digital format at CES.

 

Jumping through time again.

 

1999: THX develops Surround EX in conjunction with Dolby Labs.

 

This is just a very brief history of some of the key developments

THX has made in the last twenty years, their are many more!

 

Here are just three of the problems that are common in the translation from the cinema to the home.

 

Exessive high freqencies.

 

Incorrect frequency response.

 

poor dynamic range.

 

I'm sure some of you already know what THX post processing is,

but for you who don't here is just a very simple and brief summary.

 

Re-Equalization - Corrects over-bright front channels.

 

Bass Management - Improves Bass dynamic range.

 

Timbre Matching - Smoothes front to surround pans.

 

Decorrelation - Enhanced surround spaciousness and envelopment.

 

 

 

Now a few facts regarding THX Ultra2.

 

But wait!

 

How many people out their are listening to non-surround EX encoded DVD's in the surround EX mode? Quite a few i think.

 

The problem with this of course is when monaural surround information is played in the THX Surround EX mode, all of the surround information is sent only to the rear surround speakers.

 

Thats where THX Ultra2 comes into play.

 

Firstly THX Ultra2 is designed to improve Multi-channel film and music playback when using a 5.1 or 6.1 channel system, remember their is no 7.1 channel format, THX enables us to use 7 speakers although it is possible to have up to 8 channels for DVDA.

 

In THX Ultra2 cinema mode the EX flag is detected (if present) and the system is auto configured.

 

But what if there is no flag, or it's non-Surround EX material?

 

In THX Ultra2 cinema mode, ASA (advanced speaker array)

technology is applied to the surround tracks such that the ambient information is reproduced by the left and right surrounds and directional cues are provided by the two surround back speakers placed centrally behind the listeners.

 

For monaural surround tracks the signal is fed both directly to the back surround speakers and after decorrelation to the left and right surround speakers.

 

With discreet surround tracks (films or music),

the surround signals are fed unprocessed to the left and right surround speakers and, after further processing,

to the surround back speakers.

 

This gives an enveloping rear surround field over a very wide listening area.

 

You can still benefit from THX post processing even if you do not have a THX certified speaker system.

 

 

These are just a few facts regarding THX, hope they are useful."

 

Håper du kan engelsk :)
