quote: Brad Miller a complex will have 2 or 3 shows starting at the same time and the projectionist cannot be by each projector.
..but, there is a system to all of this:
When I was Booth MGR at a 21 plex, we would often have on the avg 3 to 5 shows that would start at the same time. Thus, the operator would start the first one, 4 min early, then run to the other one and start that one 3 min early, next one was 2 min early, one would be on time and to where the last one would be a minute or two late..esp if it was on the other side of the building...but he learned to hustle fast enough to do all of this.
NOW, being in a company where floor staff does booth starts and are needed downstairs with show starts 5 min apart (horrible starting sequences...) they start a pair of shows together-one house would be 2 min late while the other house be 2 min early, this gives them 7 minutes to be downstairs to do whatever til the next pairs are started using the same system above. Hectic in the long run but it works..(until a snafu hits and then the system is all but messed up good..). - Monte

I fell in love with X10 devices decades ago and use them all over the place in a number of theatres. Variants of them can be configured to control almost anything you can think of. We use them in our booths so that at the door, by replacing the single wall switch with an X10 module, we can shut off everything in the booth from one location, preventing people from leaving lights on in the storage room or winky lights in the work areas, or the Mr. Coffee machine (ESPECIALLY the Mr. Coffee) in the rewind room, etc.
The units can be controlled by telephone, they can control contacts for switching, they can be controlled by sunrise/sunset, they can be controlled thru walls by a little transmitter on a key fob, and as in Brad's tip, they can controlled by a timer.
The only caveat is, depending on the electrical environment, they can be irratic. In 90% of where we have used them, they have been reliable for years and years, never once being erroniously triggered. In one booth, however, they were not 100% reliable....most importantly, some receivers would go on randomly by noise on the AC lines. We have installed boosters, blockers, and amplifiers (at considerable added expense) and although in this one booth we have been able to reduce random triggers to a minimum, they do still happen.
In one system where a telephone responder is used so that the house manager can call in and turn on a camera & related equipemtn in one of the control rooms so an image can be seen on monitors in the lobby, occassionally the camera would turn on for no reason and left on for days. After trying in vain to filter devices that might be putting noise on the AC line and adding filters, we eventually gave up and just installed a module that let us send OFF signals every hour between 1am and 10am (kind of a curfew safety). I was thinking, using an X10 timer on a projector could theoretically make the system susceptible to a random ON pulse of noise on the AC line -- not a good thing. In fact, I believe someplace in the X10 manuals I recall them saying NOT to use X10 modules on dangerous and unattended devices like motors or heaters, etc.
This might be something to consider. Before I would get the timers and Universal Modules installed on the all the START switches, I would first get a single receiver module and hook it up to a light; leave it in the same circuit as the automation for a few weeks, just as test to see if it is ever erroniously triggered ON. You want to be are sure that your electrical environment is not going to cause X10 receivers to trigger. You don't want to find out after the fact that when you strike any arc, all the projectors turn on!
BTW, switching the transmitters and receivers to different system codes or set to different unit codes (there are 16 available unit codes and 16 system codes) does NOT improve limiting random triggers.

With the preshow being delivered digitally, and automatically, most places, the option of starting 3-5 minutes early isn't there anymore- you cut off the ads closest to the show, which are the most expensive ones.
NCM actually delivers a report to theaters (usually home office) detailing ALL early starts over 20 seconds. So late's not an option- now if you've got 4 or 5 starting at once, you either have to use timers or face the possibility of a show starting 5-8 minutes late, which is noticeable.
I'm dead set against timers, because all sorts of things can go wrong. Simply put, you've gotta check everything. Otherwise, inevitable something's out of frame, in the wrong sound format, or worse, getting damaged due to a misthread or bad equipment.
