THX have done much for the cinemas. When THX was first introduced it gave the visitor a possibility to find the cinemas with the highest standards.What credibility does THX have as a brand when the chain of cinemas have their own THX certified technician employed? The reason for me asking this is that I think that THX has lost it credibility when no independent person is controlling the quality on a regular basis. It seems as though when getting a cinema THX certified, the quest to withhold and increase the quality of the cinema is brought to a standstill by the owner. How do you feel about the system with THX certifiers employed at the chain of cinemas? Wouldn’t it be preferable if an independent person from THX together with the local technician would check the quality of the set-up and come to an agreement with the management how to update and maintain the system to be able to keep the THX certification. This to prevent an internal conflict between the management and the local technician. Even if a cinema is well equipped it all comes down to the projectionist to keep the presentation at the promised level of quality. It is important to maintain a high and good standard of the projectionist considering that he or she becomes more and more of a technical engineer for the cinema. BTW, is it by any chance possible to THX certify scriptwriters to keep them from making bad sequels?

We've discussed this before... My own feeling is: It is better to have THX around than not. Since you must submit your architect's theater plans before construction, at least there was *some* quality control while the theater was designed and constructed. THe THX monitor is good, but I feel the setup software (DOS only) is "not finished." Yes, it does the job, but for being a state of the art peice of equipment, the software is lacking. The R2 unit was the same; A good unit, but (again) the software was not finished. It's better now, but still a little rough around the edges.

Joe, You would be surprised to know that most of the world runs on DOS. Windows and other OS's account for a far smaller number than does DOS. Almost all industrial computers are DOS based. DOS is extremely reliable and ultra stable, easy to learn, and far more easy to adapt to a given job than any other system.......Adam, I think we have been trusting Microsoft with our THX systems since the begginning. DOS is a microsoft product, thats how they started in buisness. Almost all large light boards run on DOS as well. Microsoft however did not develop it, they bought the system. You can run an R-2 from a pocket HP computer. Gord and I both carry one as backup to our main laptops. When you travel great distances it pays to ahve it available. Mark @ GTS

I way I feel about the re-cert is the theatres is paying good money for this service, I treat my re-cert as though I work for THX (inwhich I don't), the customers expect a THX theatre, so give it to them, I had a couple of theatres that did not pass the AC NC-30 test, I could have easly alter the test to pass but I did not, if the theatre has a problem, FIX it !! I have found the high freq. was not aim correctly, I will re-aim the speaker to get the result need for even coverage, my last theatre install in December, the speakers in the THX house had a db reading from the front row seating to the rear seating of 8db diffence, it took all day to get right but we ended up with a 4db diffence on all front channel speakers in a 5-channel front screen speakers (Sony house), much moving & tilting the speakers to get this result in a 600 seat house...this was the best we can do, we had even coverage thoughout the seating area....what THX should do is do a surprise check at random to see if the in house techs is doing the job correctly, if not than take away their re-cert..I say do it right or don't do it at all, I once had a faint nosie in a aud. by ear the noise was so faint you had to really listen for the noise, but the mics picked it up, it took a while but we found the source & corrected it, again I could have alter the test, but I was there to test & correct the problem not to alter, either do it as design or don't do it at all, the theatre pay good money for a perfect theatre, then give them a perfect theatre, what ever it takes to get it....there's my two cents worth of information !!

My two euros' worth on this is that the benefits of THX are more in the design consultancy than in the recertification. All the THX houses I've visited have had reasonable sightlines even from the last seats to be sold (e.g. right at the front and to one side) and the dialogue has always been intelligible, which is more than can be said for many other auditoria, especially the hastily converted 1970s 'twins' and 'triples' of the town centre cinemas over here. So I'd say that their design people tend to get it right.However the annual 'inspection', IMHO, is more a marketing exercise than a serious attempt to enforce standards. In the one inspection process I ever witnessed, the inspector was purely concerned with the sound setup and didn't even look at a picture on the screen at any point during the inspection! I was told by front-of-house staff that he did sit in on the last reel of the last film of the evening before he started on the inspection, but even so he would only have seen one projector working in one ratio. I know of other venues where annual reinspections have been late, not happened at all or have been undertaken by a company's own engineer. This could well be because of the logistical problems of getting inspectors over from the US, but I think it would be fair to say that as a general rule, 'THX' guarantees a well-designed auditorium but not picture or sound quality. In terms of what it actually assesses, Kodak Screencheck strikes me as being a far more rounded set of tests to actually determine the overall quality of presentation, though I was not given confidence when I once got sent an advertising brochure for this programme which included a photo of an inspector gazing into an open lamphouse without wearing a safety visor.
