-
- THX has ABSOLULTY NOTHING to do with technology or decoding. It had
- NOTHING to do with Dolby Surround or Pro Logic. What it is is a
- certification for a minimal level of quality in a sound reproduction
- system.
-
- It was started as a method to bring the audio side of theater (or home
- theater) up to film standards. A great many theater still exist using
- 50-60's sound systems.
-
- The THX people have a list of 'accepted' components which meet this goal.
- The theater owner can use other compoments but these must first be
- accepted as meeting the level of quality. Surround Sound systems often
- use use the Dolby method but they are NOT required to do so.
-
- Theater must get sound checked for accoustical properties also. The
- world's best equipment may still sounds bad so acoustical treatments may
- be required. This process must be re-certified on a annual(?) basis.
-
- Home THX is the consumer version of the theater certification. The
- difference being that the equipment mnaufacturer can tag their gear as
- meeting the approved equipment list as such.
-
- No THX police will not regularly inspect your home but the intent of the
- professional certification is up to the owner. You can this have a THX
- approved decoder and a pair $2 speakers. A theater owner cannot get away
- with this but the consumer can.

-
-
- NO NO NO! There is no THX decoding. The decoding IS Dolby Pro logic.
- That's is what, in this case, THX has approved!

-
- Unless Fisher decides to raise their standard I would agree with you. I
- also tend to aggree that THX is mostly marketing but it also conveys a
- level of quality involved which is strickly R&D.
-
- No where is a THX component REQUIRED to be expensive it just have to be
- good.

-
- This is exactly the point of the THX certification.
