I recently spoke with a friend of mine that handles the construction for a theatre chain where they tried boothless. What they found was that by the time you put in a lift/elevator system and sound proof enclosure, ventilation...etc...the cost savings just weren't there to justify it. The "booth" or whatever you want to call the mezzanine floor...which need not be connected, just didn't add any significant amount over making a bunch of boothless systems. Then, when it comes to servicing the equipment, it was a slam dunk on it being a bunch cheaper (less time) to have a projector one can get to.

I'm in a new plex with such (all BARCOS): hatches in the ceiling above the VIP entrances containing the 32B units.

In the screen server room of one house, 16ft above this equipment on a platform sits a DP2K-15C unit-takes a ladder to get up to it.

Next house over, the BARCO sits on a sliding platform that comes out of the wall (I have three houses like this.

Two on elevator riser platforms that rises into its own enclosure, and two in actual closets on the upstairs VIP section which is the easiest to work on.

Rest of them located in the VIP section in the middle of the lower row completely enclosed and sound proof with seats on eith side. To work on these units entails lifting the top of the enclosure, and operating a hydraulic motorcycle work platform to raise and lower the unit that sits on this platform.

Definitely have my work cut out for maintenance sessions.

Oh, doing the modules for the 23B and 32B units takes two of us - me on top pulling the module out while on a ladder, then inching down on the ladder and handing the module down to my helper. Task in reverse on reinstalling the module.

As I said...the alleged savings diminish with each and every day of ownership.

Monte, just you wait until you have to change a backplane in one of those ridiculous boothless "booths". Let us know how long it took, how many shows were lost, how many people had to get involved, etc.

That really is the bottom line here.

And it needs to be repeated.

Remember that it takes - perversely - more power to cool a small enclosure than a large one (within limits).
I am by no means an HVAC specialist, but I am definitely confused. Please explain.

A large room takes much longer to warm up and probably has more natural heat dissipation.

I don't know if you will need that much more HVAC, but in case of a failure, you will definitely run into problems much sooner in a smaller room.

Put an oven in a small closet at 70 degrees. Open the door to the oven. Crank it to broil. How long did it take to heat the closet to 90 degrees?

Now put the oven in a typical sized projection room. Open the door to the oven. Crank it to broil. Now long long did it take to heat the booth from 70 to 90 degrees?

Tiny projector boxes are a really foolish idea.

Luckily, a smart design was created with ours: a big hole was cut below the units, which happens to be the ceiling in the same server rooms for the units above and an exhaust fan at the end of the room pulling out the air from both - the racks and the BARCOS over these holes.

Even still, ever felt all of the hot air that boils out of the back of a "C" series BARCOS? Their wasn't any design factor in the exhaust system to aid in pulling out this added hot air, which could have easily engineered and constructed since most of these units have rear end exhaust stacks instead of the traditional top exhaust.

I know, Brad - waiting for when I have to replace the rectifier units in some of these BARCOS where the entire unit have to be lifted up to get to the back ... but, it's not my problem-my hands are clean of this..it's what the building designer ordered and has no idea on this stuff.

A typical case of a boardroom decision where the technicians were not invited in the final say.

The only version of this that I have seen is in a hotel, of all places. There is an existing fully equipped 35mm projection booth in that venue (which, in a previous incarnation, was a full-time movie theatre), but the hotel wanted to be able to divide the space in half by means of a curtain and still use the D-cinema video projector in the front half of the space. As a result, they ended up with a custom-built wooden box suspended from the ceiling, with a Christie CP2210 inside of it and a custom-built exhaust system for the heat.

The setup sort of works (the Christie touch panel and Doremi server are in the projection booth, along with the 35mm equipment), except that the box is not particularly soundproof, and replacing a lamp or doing any other maintenance requires rolling in a man-lift, which could never be done with an audience in the theatre (it would block an exit).

This was probably the right thing to do for this special-venue location, but it really is not the sort of thing that would ever make sense in a commercial cinema. The only exception that I could imagine would be if the existing booth is very cramped and there is a need to keep the film projectors in place, but, even then, it would be a bad compromise.

Not being able to service the machine easily in the event of trouble will someday result in lost shows and unhapy patrons, which is something that no theatre owner wants.

What's the current state of "boothless cinema," remote control rooms (including servers, sound processors, etc.), and behind-the-screen amplifiers?

In general, is the distance between the sound processor and the amplifiers becoming significantly larger than the typical few meters?

If so, what percentage of screens currently have a significant distance between the sound processor and the power amplifiers?

Is this percentage increasing?

THANKS!

Harold

Along with Monte, the theatre I manage is basically boothless too..I do have 6 out of 13 Barcos in what used to be the old booth from the original six screen, but, the floor has been raised (to get more ceiling height in the hallway below) So there is approx 4-ft room height w/ all the electrical conduits, & ductwork running rampant through it! So I have to crawl upwards of 200 feet to get to the farthest projector! If I try and duck-walk, I get too many cuts on the head from overhead piping! (I'm 6'4"!) The rest of my projectors are in soundproof boxes that the projector is lowered down by a hand winch that takes two people to do, one to get on a ladder and pull safety pins, the other to lower / raise the platform with the winch that is located behind the screen! Then when the projector is down a few feet the exhaust, power, Cat 6 & BNC connections have to be pulled so they can be lowered far enough down to service!(not enough service loop) Then the opposite is in store when returning the machine to operating position!! Plus, they don't register the same in the box every time so we have to reset the lens files after every service! My one and only 32B is located in a doghouse on the mall roof! Accessible only by a hatch in the wall about 8ft above the last row! Try placing a ladder and climbing in there when there is an issue with the projector and there is a full house! Been there, done that!! Not fun! I built a spacer out of 2x4s so I could pull the lowered projector out from the wall far enough to be able to replace power supplies! (Done this 3 times now on different machines!) Needless to say, I am am very opposed to any 'boothless' type installation!!! To address the issue of sound...most of my systems are running 200-300 feet of speaker line from the amps !! They did install twisted 2 pair #10 jacketed plenum wire so we don't have any crosstalk issues, but the power loss and sound delay was another interesting factor, as well as the installers had to install wifi so the EQ could be done as most of the Dolby CP-750s are hundreds of feet away from their respective theatres!! Plus, I have a 200ft plus run of analog sound from a cable box to the CP-750!! for our special events!! I used the best Belden shielded cable I could get, and it actually sounds pretty good!!

Is Carmike Cinemas going the boothless route in their new theaters? I was doing some image searching through Google related to premium priced theaters and found a few like the image below at new Carmike theaters:

 -

This image was reduced in size according to forum limits, but the original high resolution image can be found pretty quickly through Google Images.

Obviously Carmike is copying a visual I've seen at a few film-based IMAX theaters (dome screen theaters in particular) where a bunch of the booth gear is on the ground level behind glass windows for the movie-goers to see. In this case it's all the servers, cinema processors and amplifiers. Numerous pipes and conduits rise from those racks leading to the projectors, speakers, etc. But are the projectors in a traditional booth or are they hanging from the ceiling in the auditoriums or crammed into some other hard to access compartment? Either way it looks like a real pain in the ass to keep all that wiring organized during installation.

One thing I do like about that approach of putting the booth racks behind windows for customers to see is it gives the theater another way to market sound and projection presentation to the movie-goers. The average person can see that isn't the kind of hardware you could pick up at Best Buy. Of note: this must be the AV rack room at the Carmike 13 in Champaign, IL. It's the only theater Carmike has that is equipped with Dolby Atmos. The nearest three or four racks in that image hold the Dolby Atmos related gear (most of it being amps). I like the visual touch of them adding Big D Experience and Dolby Atmos lighted signs above those racks.

One downside to this approach: if Edith Hinklebottom comes out to complain to the manager about the sound being too loud, she might stand outside that booth rack room to make sure the manager turns down that sound fader.

I can't help but wonder if boothless cinema is really a ploy to further reduce theater staff. If the projectors are stuffed in the auditorium ceilings or other little cubby holes and the booth racks are all concentrated into one room then maybe the manager's office can be built downstairs in the lobby. There's no need to have an upstairs area at all where the GM or any assistants could hide and potentially goof off. They can stay downstairs popping popcorn, selling tickets, counting drink cups and other inventory related stuff and lessen the need for all those high school kid workers bloating those payroll numbers.

The best of the booth less cinemas I have seen yet is the Aksarben Cinema in Omaha. I believe it's ten or twelve screens.

They built a large-central glass enclosed room just past the ticketing stand that houses all the support equipment, minus projectors of course. They also did long speaker runs from the amplifiers to the auditoriums and all the cabling is running all over the ceiling in cable trays that are perfectly visible to the folks attending the place, sort of as though they tried to make the cable trays part of the open ceiling design. The longest run there is just over 400'! Some of the cable trays are lit up with blue LED's so it looks kinda cool.

When it came to the projectors, they did it the right way. No booth or mezzanine but there is an individual closet at the back of each auditorium that houses the projector and the port is in the door itself. Each projector was mounted in a slide out tray with a lazy susan turntable on it. So you slide the projector out and then rotate it to change the lamp or to work on the projector. Strong custom built the slide out trays for the chain. These slide out trays were uber heavy duty and had pins to relocate their exact position. No after the fact re- adjustments are necessary.

I have many pictures of the Aksarben Cinema and I will post as time permits.

As for the ceiling lift devices. It's probably the dumbest thing anyone ever came up with. In the majority of theaters the ceiling is the dirtiest place in the entire building. Just the necessary frequent cleaning of the Barko air flters has to be a nightmare. I'd be coming up with some sort of retrofit Heppa filters for those projectors in a hurry!!

I grabbed this picture of the Omaha location off the net and lowered the contrast a bit so you can see the long cable tray on one side. They actually sent the dual HDSDI over 400'.

That looks more like an airport car rental area than a movie theater.
