Kodak used to have a excellent machine made in germany called the SAE or SAV machine
We had several hundred of them for years here at ont place running multiimage slide shows and outside of lubing blowers there all metal construction was great
Regretably they all got sold as a job lot years ago

Sara,

If done right a slide presentation could be neat in your case. Use fades between slides. Get the art/photo people to make your slides, and give em' credit. (free slides and good PR for your theater)

If you were running a commerical for profit moive theater....NO SLIDES!! I love to hate going to my local mutli and seing these puke presentations of slides. Dim,dumb,and dull-but dollars!! The all-mighty dollar....

We have the same model Kodak's Brad mentioned and every problem he mentioned as common in his experience is also in mine.

Yes I too have used those machines before and they are a constant bitch to deal with. That model should be discontinued as it is destroying the Kodak name.

We have two types of slide projectors, both made by Kodak. One is a "Medalist AT" and the other is a "Ektagraphic III A." I suspect they are pretty much the same. They use a EXY bulb which is 250 watts. The "EXY" is a standard "number" for these types of bulbs, and are avaiable from several companies (ours are from Osram.) They project an apx. 12ft by 12ft image about 50-60 feet away with an "OK" brightness (but there are no lights on or near the screen.)

I don't know if this is the same lens that came with the projector. Most of the lenses that come with slide projectors have a zoom feature to fit it to your screen. But, they are usually not meant for the larger size screens used in theaters. You should find out what lens will fit your theater before you buy.

As I said, we get about 3 weeks out of a bulb. That's from about 1.5 hours on Monday-Friday, 3.5 hours on Sat & Sun for a total of about 43.5 hours of bulb life. Note that the filliment in the bulb becomes very brittle after the first time it's lit, so it's very important not to move or jiggle the projector. Otherwise it will break, and have to be replaced. If you were thinking of setting the projector up, then removing it to store somewhere after each night, you will have to replace the bulb much more often.

There is a fader unit with our projectors. It is made by a company called, "Entré." It is a model "D100 Single Projector Fader / Dissolve." It plugs in the back of the projector.

Apx Prices:

From: http://www.cambridgeworld.com/projector_viewer.htm

I don't know if these people are good or what; I just wanted to get some idea of prices.


Kodak Ektagraphic IIIA $339.95
KODAK CAROUSEL MEDALIST $266.95
ENTRE DISSOLVE D100 $138.95

Maybe I'm the only one, but these projectors have worked OK for us. I find that, out of 10 new projectors, maybe one will develop problems shortly after use. Usually, the tray feeder jams up. Also, the socket for the bulb gets messed-up (from bulbs being changed so often.) Usually, with a little TLC you can get them running again. My suggestion is that if you buy one, turn it on right away and make it step through slides (with and without the bulb on) to find out right away if it's going to last. I mean, don't leave it on for a week constantly, but maybe for 5 hours one day, another 5 the next, so if it dies, it's within the warrenttee period.

The Kodak Ektagraphic slide projectors (at least the III-AMT model, anyway) come with the 300-watt EXR lamp as standard, a lamp with a 35-hour rated lifespan. Since the EXY is rated for 200 hours (IIRC), I think that's the reason for its use in projectors for slide advertising. I guess reduced lamp changing frequency is more important than image brightness.

Sara,
I own a three screen theatre and after much consideration, installed slide advertising. The boost to my gross income was incredible. I use Kodak projectors, I have a timer for them that shows the slide for 13 seconds, which research showed was the time needed to grasp the patron's attention. I use an FHS bulb, get about two weeks out of it, and make a nice profit. Any other theatre owners may agree that it all boils down to what it takes to keep a quality presentation, and pay the bills.
Email me if you would like detailed information on what I do here, it isn't hard to get up and running.

oh, I have it tied into Gord Mcleod's automation and it is fool proof

Lance, do you have any focusing problems with your slides set to 13 second intervals? I was told never to set them higher than 10 seconds, or it will emboss the slides to the point when new ones are loaded, the older ones will project significantly out of focus. I've never personally tested it. I just set the timer to 9 seconds and forgot about it...but I'm curious as to the validity of that precise "10 second maximum" rule. Of course, even at 9 seconds, I still had focusing problems between the new and old. Perhaps that is just the "acceptable" point?

Brad,
No, I do not seem to have a focus problem. But, the throw is only in the area of 56 feet. I purchased these projectors from a firm that does screen advertising, but did not want to come into my market because of limited population. This company had done research on attention span( or so they told me) and sold me the timers based on the research. They claim that if it is shorter than 13 seconds the slide is not effective as an ad. I do change out the slides on a regular basis so that we have good quality ads on the screen.
Of course this company also told me to take the heat obsorbing glass out of the lamp unit if I wanted more light on the screen, which I didn't do. I have had these projectors for 4 years, had to replace one lamp holder which Kodak sent me right away, and that is the extent of the problems. Oh, and they are ektagraphic III's. I justify it that these babies allowed me to have Gord come down and install a Panestereo with DTS, And I never hear complaints about the ads, just good comments about the sound!!!

Glad to hear you haven't had any problems...and kudos to you for actually taking some profit and putting it BACK into your presentation!!!

Very few people today seem to do that, Ian and Ky are the only exceptions that come to mind.

I'd tend to think that any focus problems would be more of a result of the kind of slide mounts in use than of the duration that the slide sits in the gate, unless you have a xenon-modified Ektagraphic or something similar.

For this sort of application, you really need proper "glass mounts," which sandwich the slide between two thin pieces of glass in order to keep the film flat in spite of its natural tendency to curl with heat. Glass slide mounts are available from any decent camera store for about $.25-.50 each (usually in boxes of 25 or so).

My business has 25 Kodak Ektagraphic AMT machines, and 5 Kodak 4600's that I got for pennies at a school auction. They are used almost daily by knowing operators, and idiots. The only problems I ever have are lamps being installed wrong, the lens being installed wrong, or the carousel tray being broken because the operator tried to force it off of the unit.

The AMT units, for some reason, seem to be louder running than the 4600's. Must be a different fan assembly in the AMT's?

I use my 4600's at Biltmore Estate functions mostly. Their gatherings seem to be more upscale. The black housing on the 4600 vs.the grey housing on the AMT looks better with all my black stands, drapes, and equipment.

Our AMT's are 12 years old and only a couple have been opened for repairs--usually because of operator errors, or something being jammed into the fan. The lamp sockets are getting rough on a few of the machines. I have bright-light modules for most of them, but I really dont notice a big difference in the brightness.

Who knows how much use the 4600's have had? I got them because of the auto-slide focus feature that seems to work really well. They were nasty looking until I took a small brush to the slide changer area.

We use Apollo EXR lamps that are more inexpensive (cheaper) than GE's. I dont replace them very often, but I do always include a spare in the carrying case.

If the projetor jams, 9 times out of 10, it is a bad slide tray that is warped, or bent. I've never had the constant change problem that was mentioned above.

I like using the Ektagraphic, and 4600's. I dont love them, but I do like them.

I dont like the TORX screws. Who's idea was that? Trying to keep me out of it, I bet! (smiley face goes here)
