"I think removing the changeover douser completely is a terrible idea."
Wes, if you think it is a terrible idea, please give us reasons as to why you think this is such a terrible thing to do. Otherwise your post will be completely useless to the readers. This is actually a fantastic idea. Imagine you are running a multiplex and you need to be able to rely on start timers...but oh no the dousers don't open on their own because you have the older style! What about those older dousers that melt and you have to physically fight them to open/close? Douser solonoids that have died are just another problem. Then there are the occasional dousers that like to fall down during a show. Yes, your patrons will love you for that. Putting the xenon on the exciter circuit completely eliminates this problem and gives your patrons the EXACT same show on screen. Plus you will never again change out a douser blade or solonoid. That's money, labor and anguish saved. Manuel, it only requires moving 2 wires.

I think that when you remove a changeover you are disabling an important part of a projector. It may be good to solve a problem temporarily, but the ORIGINAL problem (sticking blades) should be addressed and corrected. Altering the basic design of the machine seems ridiculous to me, even if the original design was terrible to start. Little things could be an issue...like what if you don't have the appropriate opaque leader on hand to properly set this up? Seems silly, but it certainly would eventually happen in a real world mega-plex booth. Then you have someone using the hand douser or putting their hand in front of the lens....or, doing nothing at all using a clear leader. And, you have effectively "redesigned" the automation...and that is assuming that one even has automation capable of being rewired to control the lamphouse. I would be SLIGHTLY more inclined to agree with you if the machines being crippled of their dousers had working fire dousers, but many newer machines do not. I am, however, a slight bit of a traditionalist, and I am partial to Century and Simplex (older) equipment. I do not have any problems of note with my changeover blades, or with my zipper and kelmar solenoid units. I have the luxury of being able to choose the equipment that we operate...I know many of you do not and have to work with what you've got. So one reason I think it is a bad idea is simply because I have no issues with what I operate. In the end I just want something more than a hand douser to control the light in my machines. I could probably think of more reasons if I thought long enough... I might like this idea more if I was exposed to it in a real operating situation...but right now with my machines, the dousers stay for certain.

[sarcastic] Great philosophy! We should all just conform! Manufacturers know best. Us people who actually use the equipment every single day aren't too bright and should just rely on the manufacturers to solve problems. [/sarcastic] Most significant design changes come from the field. Read the review on the Speco LP280 Digital Platter in the Reviews section of this site.
