Hi Folks,
We're having two NC1600C's and a NC2500S installed in a month or so.
Does anyone have any experience with these beasts and if so, any pointers on their use?

All I can say is that the 2500 is a rats nest inside... like it was just thrown together. A local chain has quite a few 2500's and they've been pretty reliable and the picture is very good. They however do not have the light output the current crop of Christie projectors has.

We use both the 2500 and 1600 where I work.

First off. I don't see much of a need for the 2500 anymore. In our location, we had it installed for the release of Journey 3D. Since the 2500 uses the 1.2" DLP chip, it couldn't handle the full resolution 3D. ( I hear that the new 2500's have a new board that can handle the full resolution) So we basically paid extra money for a projector that can support a 6k bulb instead of the 4.5k bulbs in the 1600. But since we have to scale, we are losing light & resolution. We also had a problem with one of our units detecting the main internal fan. The fan was indeed working fine, but NEC sent us a newer mounting bracket for the fan switch. It has worked great ever since.

If the 2500 still cant support the full 2k 3D resolution I would go with the 1600.

On the 1600, we (and other independent theaters we know) have had problems (notice the plural) with the fan above the light engine. It collects oil which can drop onto the light engine and cause a very large "spot" on the screen. NEC is insisting that it is caused by popcorn oil. We think that is a bunch of bologna. Our 1600s were installed in December, and all 8 of them, including those furthest from the concession stand) had a large build-up of oil on the fans. We therefore think that the oil is coming from the bearings inside the fan. Other independents that we have talked to received a new style of fan from NEC, and they have had no oil build up since.

I also like the 1600s more because the power supply is built into the projector.

One more downfall. Neither model is HDCP complaint, so no Blu Ray.

The 1600 is HDCP compliant...you MUST use the MM2000, with the HDCP compliant DVI module though. Note, this is the built-in version, not the stand-alone.

It most likely IS popcprn oil. I fond this all the time in lots of different projection equipment. If your popper is not exhausted(properly) to the outside then the equipment will suffer!! Note too that some types of popcorn oil migrate much worse than others do.

What's the deal with popcorn oil getting into the projector compartment anyways.

The only avenue for air to enter into the engine compartment on a Christie projector is through the "operator side" intake, and that has a hepa filter installed. (im only referring to the CP2000 split body, not the ZX or M)

I would expect the same filtration on NEC projectors, is this not the case? Is outside air forced into the compartment unfiltered?

Not having used the kit....the Manual clearly states that inadequate ventilation will cause problems with the cooling....popcorn oil may be a clue?
