Yes Digital Cinema is happening...

But I'm hoping I have a least 5-8 years to use these 35mm projectors and I want digital sound.

Canada seems kinda slow on this digital thing, I think they only have about 6-10 digital screens in the whole country.

AMC is building a huge new complex at Younge and Dundas in Toronto I wonder if they will be digital cinemas....

One final question can the DA20 run with two projectors? most of time it will be a plattered film...but flicks we only play one or two nights will be change over on 2000ft reels

anyway thanks for the info... I guess i'm on a hunt for a CAT 441

Then what's the problem? 99.9% of people think CDs sound better than LPs, which is why CDs are now the dominant music media even though many people SWEAR that LPs sound better. The same is happening (or will happen) when digital replaces film across the board.

The DA20 can handle 2-projectors just fine. You will need motor-start logic lines to feed the DA20 so it knows which projector to look at and when. These can be of the form of a relay whose coil is across the motor windings or a double pole switch (one pole is for the motor, the other is for the DA20...don't cross them).

The problem with LP's is that to get the most out of them requires an expensive setup... SACD's or DVD Audio discs will typically blow the pants off the same title LP. CD's have gotten better and better all these years for sure but it seems that some Mastering places never learned to produce decent Masters.

Just like film prints...it definately seems to be all over the place. I have some LPs that just dance all over their CD counterparts...then again, there are some pretty incredible CDs, SACD, DVDs out there. I don't think you could come up with a hard and fast rule that says an LP of the same recording as a CD will guarantee you a superior result. Sound is so subjective anyway and there are MANY MANY permutations that go into how something sounds either digitally or analog...you will always be comparing the setup as well as the media.

With all the screens that are ripping out film projectors to install D-Cinema, I'm surprised there isn't a large supply of film sound equipment on the used market.

2. Because Digital media is compressed in any way you see it. You can compress and reach to a high level but NOT film standard although today the difference to a customers' eye is not noticable.
A little off-topic, but I see this coming up time and time again. Remember- over 85% of films, and nearly 95% of films with digital effects, are scanned and color corrected digitally. Used to be nearly entirely 2k, but is now increasingly 4k, though 4k is expensive and therefore post houses have been slow to adopt. Then they're printed back on film via a DI (digital intermediate) process that creates the internegative. This started recently, with O BROTHER WHERE ART THOU being the first film to go through to process (at 2K res), but it's quickly become industry standard.

So virtually every film you run now is already maxed out at 4k, and often 2k. There's additional compression to get it to D-Cinema, but increasingly not enough to really notice. You can occasionally even see digital artifacts in 35mm prints (KILL BILL comes to mind).

But don't get me wrong, I still think D-Cinema generally tends to look like canned crap.
