I have just been looking at the photographs, looks a nice setup, but I have a few questions:
1. How big is the auditorium, it's difficult to judge from the pictures.
2. Any chance of some close-ups of the CDS processor? I've seen one of the readers, but never the processor. Is there any film to play through it?
3. Why two aux units for the CP-200, what options are installed in them?
4. Are there four power supplies for the CP-200, or am I mistaking them for something else? Most CP-200 instalations I have seen have two PSUs, one in use and one on standby, but I have never seen four.
5. What is an 'HTPC'?
6. What screen surface does it have?
7. Was it created within an existing building, or built new from the ground up?

Is the F-T screening room available for functions like private screenings for critics or anything like that?
How often is it used?
Have you given any thought to conducting projectionist training seminars there? ![[Smile]](smile.gif)
What a great place to learn Film Done Right!

Is the popcorn made with canola or coconut oil?

I understand that security for the screening room is provided by Cordell Walker Texas Ranger. Is there any truth to that rumor.

Yeah Brad, 4 PSU-1s? Even I'm inclined to think that's overkill. Or are you somehow wiring the outputs in parallel, i.e., two pairs of two?

On CP200's it can be made a lot quieter if the MPU runs of a seperate PS than the main processor

The auditorium is approximately 24 x 26.
I'll post some pictures of the CDS system.
The Aux units are a coveted item for CP200s. There weren't many made and they are extremely hard to come by. For awhile I was going to use it as a modified EX decoder, but ended up with an SA10. Currently it is a backup and also serves to hold a spare set of cat64B cards in the event someone wants to come in and rent the room who wants to do their own tuning. (Got that handy trick from John F. Allen.) Since all of the wiring comes into the rack right behind the spare Aux unit, there really isn't any other piece of equipment that could've been mounted there anyway. It's either store it there, or put up a blank panel. The same goes for the other racks, as I am adamant about spooling up an extra 10-15 feet of speaker leads at the bottom of the racks in the event I ever need a little bit longer stretch for a future upgrade.
Yes there are 4 power supplies. Two run the CP200, the third runs the MPU, the fourth is a spare. If anything goes wrong on a show, I can be back up in 15 seconds.
An HTPC is commonly called a "home theater personal computer". It processes and upconverts video images for the DLP. It also has a DVD drive in it so I can play DVDs straight off of it if desired.
The screen is a Harkness Microperf Spectral 2000. It is the best screen surface I have ever seen anywhere. Highly recommended.
New building construction.
If critics wanted to make the drive outside of Dallas, they are certainly welcome. Some studio people have been over to do some film inspections before they charged a theater for damaged film.
It is used less and less with my schedule, but a few times a month assuming you are just talking about me.
Projectionist training seminars would probably be best suited at an actual multiplex where more of a "real world" scenario could be had.
There is no popper, but when the time comes it is added, there will be no stinkin' canola oil.
There is no such person as Cordell Walker Texas Ranger, although we have kicked Chuck Norris out of the screening room before. He tried to fight, but he is just too much of a wimp.

Be still my heart. Brad said:

I bet the next thing he will tell me that Hayes Cooper
wasn't one of the original Texas Rangers.
Why even our film-tech friends in Europe and Great Britain know of the exploits of the revered"H.C."
Matter of fact, Phil Hill had a crush on Alex Cahill note the similarities in the name. ![[Eek!]](eek.gif)

Brad,
Awesome auditorium and booth you have there! But I wonder why so much speaker power? You probably chose JBL4675 to have a THX-compliant installation (plus the huge subwoofers) but for such a small auditorium, wouldn't the THX-certified JBL3678 screen system have been sufficient?

Hi Brad,
This screening room it's absolutly terryfic ! I'm really impressed.
Just some questions:
-I'm surprised that the wall between the both and the auditorium is so thin. I mean only two layers of "fibro-cement" (sorry I dont know the right term in English) and one layer of wollrock are suffiscent in case of fire.
For example in Switzerland and most European countries, the wall must be 20 cm ±0,7 feets tickness. And the wall muss resist fo 90 minutes if is exposed to the fire.
What are the local requirements in United States for this part of an screening room ?
I was surprised too that the wall carpet is installed before cutting the wall to instalt the port window. How did you to not be disturbed by the dust ?
A verry nice equipement, and a nice auditorium. Congratulations !
If you don't seal Pop-Corn, may I take a KFC fried chicken to eat during the show ? ![[Big Grin]](biggrin.gif)

Jean-Michel Grin,
The Film-Tech screening room is in Brad Miller's home. There are no codes written for home screening rooms. Brad has complied with all he knows about building codes for commercial installations, but no enforcement officer is going to look at his screening room. That is unless he is a neighbor and invited over to watch a film.
I believe on his house plans that room was listed as a second garage or a hobby room.

I know that Brad made the room as absolutely flammable as possible just to spite real theater fire codes which drive him nuts.

Brad's screening room is indeed fantastic!!! It sure beats his last setup with projector and sound racks in the kitchen. I can't figure out is where the IMAX projector will be installed. Also, how could any screening room be complete without 8mm and 16mm projectors?

The 3678 is not a great speaker...it's response is actually rather poor since it's horn can't go low enough in frequency range.
For a "high-end" THX approved speaker of "appropriate" size, the JBL 5671 would be the preferred choice.
If you want a two-way version, use the JBL 4670D-HF combined with the 5671's LF cabinet (I think it is called the 5641)...then you will have a small 2-way system with proper drivers and response. However, with the small horn you should shift the crossover up to 800Hz since the small horn has no pattern control. So for better pattern control you would get the JBL 4675C-HF (large horn) and put it on the 5641 LF (single 15" cabinet). But...you will loose about 5Hz of LF response as compared to the 4675....so you are back to the 4675!
If it were me...I'd probably use the 5671 but there isn't a damn thing wrong with the 4675.

Great points given..............ah.......now only to see the photos.

Lionel, I chose the 4675 because it is the best sounding speaker on the market that would possibly fit in the room. (The 5674 just wouldn't fit! ![[Wink]](wink.gif)
) I've never cared for the 3000 line. They just don't sound as good and the LF is lacking with only the one woofer. Even in a small commercial theater I will put in the 4675s. I don't like to strain for output and the 4675 fits the bill for just about everything with a 40 foot or smaller screen. Couple that with a bunch of QSC amps overspec'd for the room and the end result is a nice system that never, ever has to work hard to be able to take people's heads off when the need arises.
Jean-Michel, as Ian said the screening room is in my home. I drove the builders nuts with all of my requirements for the room and I was able to achieve *most* of them, but city code and what the builders were willing to do prevented a few things (including my preferred booth wall). In regards to the electrical, it will pass under any commercial building requirement. I figure if I wired it for commercial code, no one would complain.
Steve, the 5671? If we're going to go 3 way, don't pass up the 5674!

Brad's screening room is indeed very impressive. Not only is it well thought-out and engineered, it's located in a separate "wing" of his house so as not to disturb the other living areas. I must confess, I am guilty of violating one of the 10 commandments... the one about not coveting thy neighbor's goods...
Oh, and Bob, W(ho)TF is Alex Cahill? I mean I have left a trail of many broken hearts in my time, but I don't recognize that one.
