I really like to have experience with every kind of digital sound in cinema’s as long as it is possible with the upcoming D-cinema…

---

From my very limited experience with digital cinema the sound doesn't seem to use any of these systems; it's uncompressed pcm in up to eight channels; only six normally in use. I don't know the sampling frequency, or size (number of bits). This is carried from the server to the sound system as four AES pairs, all on a single cable with 25 pin 'd' connectors. We are also using a CP-65, with a Dolby DMA8 Plus to interface the AES streams to the six channel analogue inputs on the CP65.

I don't know how you would add SDDS to your system; I've only ever heard SDDS once, as I understand it, the unit is not an add-on adapter to an existing processor, like a DA-20 or DTS-6, but a complete processsor in its own right.

Just out of interest; what would be the going rate for a secondhand DA-10 or DA-20, and a pair of readers, preferably the original ones (Cat. 699 I think). It would be quite nice to set up a system using the original readers as when the system was introduced, in the home cinema where I put four-track mag in a couple of years ago. They still show one or two films a year in it.

My question was not about d-cinema... I know d-cinema has 8 channels that will be used and 16 channels waiting to be used in the future. My bad, I'm Dutch... I must read the things I write before I post them.

As long as I can work with 35mm prints I want to have worked with SDDS, Dolby, DTS, etc... because it is going to be replaced soon by d-cinema... (yes uncompressed PCM sound). I really am a sucker for good digital sound in cinema's.

For a second hand DA-20 you really have to look hard. No cinema would depart from it easily. A second hand DA-20 isn't cheap... +/- 5000 Euro's (6,583.14 USD, 3407.5 GBP) for the lot (penthouse reader, unit, etc. ) isn't an exception (in the Netherlands).

One and possibly the only "selling point" of SDDS is that it can be easily added onto any sound processor. Theoretically, you could drop a DFP D-2000 onto a Kelmar mono if you wanted too, or run it without an analog processor (highly not recommended as SDDS has shown to be unreliable). The 2000 series decoder "hangs on the end" of your existing cinema sound processor. The outputs of your processor L, C, R, S, Lfe are connected to the inputs of the DFP D-2000 and the output is connected to the inputs of your amplifiers. The "2000" carries its own B-Chain settings accessed through a PC with the set-up software that is used when it is playing digital. In bypass operation the analog signal from your CP passes through the "2000" untouched and into your amplifiers. It can be confusing for some operators because there are separate faders for analog volume and digital volume. If I remember correctly the "3000" series has a built in analog processor. Sonys analog processor that could be added to the "2000" series or used as a stand alone unit was the DCP-1000.

Ideally, you should look for a DFP-D2500. That's *in principle* the same as the DFP-D2000 described above, but a newer unit and it also uses the DFP-R3000 reader which is much better and more reliable than the old DFP-R2000. The DFP-D2000 processor is not the most reliable either. There is a certain risk involved in installing these. Installation as such is not very difficult at all if you know audio cabling and alignment, not any more difficult than installing a regular processor (and quicker).
I have no idea where you might find used systems in general or a DFP-D/R2500 system in particular these days in Europe, and how much you would have to pay for them. I have a few contacts and have to see what they say.

What type of projector do you use?

I picked up 2 DFP-2000's and 1 DFP -3000 on eBay a about 2-3 years ago. One DFP-2000 came with 2 readers (whoever had it had used a 2 proj setup). I paid $500 for it. The other one had no reader, which obviously didn't matter since I had an extra reader at the time. I paid about $150 for it. The DFP-3000 came with no reader. Coudn't find the paper work on it but if I remember right I paid about $750 for it and then ordered a reader from Sony about 2-3 months before they announced that they were discontinuing SDDS. All units work fine, although I did have to replace the LED's in the DFR-2000 readers, which weren't all that expensive. I have another DFP-2000 that was installed back in 1994 that has had zero problems except for replacing its LED's.
