What is the absolute minimum amount of equipment needed to project 35 mm film?
I'm guessing one platter and one projector
or two (modestly) priced projectors using
the old single-reel changeover method.
Splicer
Rewind
Amp
Make-up table
Some extra reels
what else?

Having only used carbon-arc lamphouses, do
Xenon lamphouses need to be vented as well?

I've got the auditorium, seats, screen and two high-quality floor-standing stereo speakers. The throw is short-about 50 ft.
Need advice on best platters/projectors.
Have never used a platter-only two Simplex
projectors in tandem, so I know nothing about
platters. Not adverse to using two in tandem again-if the price is cheap enough,
although I'm willing to move out of the 19th
Century and use Xenon lamphouses.

One last inquiry: Do Xenon lamphouses operate on A/C or D/C current? Have some
old extra-heavy copper rectifiers but don't know if I'll need them.

Any of you guys with equipment to fill the bill, let me know.

Thanks much.:confused

DC Rectified Usually converted from 3 phase AC but there are single phase out there.

I don't know if carbon arc rectifiers would do the job. ( I am not up to speed on carbon arc)

Mucho ventilation unless you like hot quartz splattered all over.

need some sort of preamp

lenses

my favroites

Simplex projectors
Speeco Platters

You left out:

Soundhead

Sound processor/preamp

Exciter lamp power supply

xenon lamphouses need a power supply

Automation unit

Sim: you're almost there. Get someone to start hooking it all up and they'll show you the rest. Get a platter. Get ventilated: a bulb gives off +/- 10 zillion degrees: try that in a closet in the summer time.

Is this for a theatre, or a personal screening room? Lots of good used equipment on the market. Platter is a good choice for multiple showings, changeover with two projectors if you have few showings of a feature or don't really need automation. You can start with the basics: platter, make-up table, splicer, lamphouse, projector, analog sound, screen, speaker(s) and move up from there. Arc lamps should be vented!
