Does all this humor mean that the list of Cat. Numbers is complete? [Razz]

Are all the cards from the CP50 there? Which one is the one that flips around and actually has two Cat. Numbers?

I had an original Cat 69, but a Cinemeccanica V5 ate it. [Frown]

The Cat. 116L is the one that flips around to do dual duty. The Cat. 115 only fit on one slot (where the Cat. 160 or 560 currently resides)

I can add another one, though not a very interesting card:-

Cat. 134 Link card used in MPU-1 when Cat. 93 12 kHz. surround channel switch card not installed.

Steve, what is the function of this card, and whiich units is it used in?

Looking at the prices listed above, no doubt long out of date, but comparisons are probably still valid, and certainly were at the tiime that the Cat. 222SR/A was introduced:-

Cat. 222SR/A 1315

Cat. 222A 565

Cat. 350T 595

1x Cat. 222A + 2x Cat. 350T = 1355

If these figures are correct, what's the point of using the Cat. 222SR/A in a CP-65? For an older unit you would also have to spend another 50 on a Cat. 565 backplane adapter card.

The Cat 116L was used in the CP-50 once it started to ship with the Cat. 150 rather than a 110 an 116 combination. The 116L was the equivalent of a 115 and a bypass for the 150 as well. I saw one poor CP50 where the owner cut the 116L in half and bypassed both the 160 and the 150.

As for the 222SR/A....there is never any good reason for using it. It is not a very good SR decoder. In a CP65, the Cat 300/350 was always a much better choice. The Cat. 222SR/A only sold in CP65s, when new, since a theatre owner could save money. As an upgrade, you are correct, a pair of Cat. 350s is the cheaper and better solution.

Actually, the bypass card was a Cat. No. 110L, not a 116L. I remeber things from 20 years ago better than from yesterday.

As I recall, the airplane/marine analogy for the cell leads (red=left; green=right) is correct. Ioan Allen was once in the british Navy and this dates back to the 1976 era. Cheers!

Steve, am I missing somethiing here? The cost diifference between the 222SR/A Vs. 2x 350 + 222A cards is only 40; not sure whether this list is in Pounds or Dollars, but it tends not to make much difference, the higher prices of most things here tend to make the fgures similar. Anyway, it's a very small amount. I can see that the 222SR/A would be more attractive price wise in a new processor than in an upgrade where a 222A was already available, but even in this case the difference is so small as to hardly be significant. Add to this the better sound quality with the Cat.350, and the possibility of being able to continue to run in stereo (A type) if a 350 fails until it can be repaired or replaced, and the 222SR/A does not look very attractive for a CP-65. Of course, if a Cat. 222 SR/A does fail in such a way as to be beyond repair, then the replacement cost will also be high, as would the cost of keeping a spare card in stock, much more so than a Cat. 350.

All this assumes that the difference in price of the cards was reflected in the price of new processors fitted wiith them. If Dolby fixed their prices in such a way that the 222SR/A option was much cheaper when purchased in a new processor then it would become more attractiive, but I can't see why they would want to do this. The 222SR/A is a very expensive card; if it had been much cheaper, say half the price that it is, then it could be an attractiive way for a cinema on a small budget to install SR, and I could see the point in it, but not at this price.

Am I correct in thinking that the 222SR/A is decode only? The 350 is encode/decode, albeit with encode disabled in the 'T' version. If this is the case, then surely it should have made the 222SR/A significantly cheaper; it just seems like a very overpriced card to me, even leaving out any difference in sound qualiity. I've only ever seen one, and only heard it through the monitor speaker in the box, so I can't really judge this. In what way does it sound different?

What is the Cat. No. 222B Two-channel IC based SR upgrade module?

The silk screening inside the front panel of the CP-65 says that the slots which normally hold the Cat. 350 cards can also take Cat. 300 for SR/A or Cat. 450 'A' type. I know about the Cat. 300 option for four channels of 'A' type for certain magnetic formats, but what is the 450 opton for? It would seem to give you four channels of 'A' type, but no SR. Given that SR already existed when the CP-65 was introduced, and quite rapidly became standard on new productons, it's diifficult to see why anybody would want this option.

Welcome to the weird world of Dolby

The First CP65s (no suffix) had a pair of Cat. 350s and a Cat 222 for 2 channels of A and 2 channels of SR.

When the Cat. 222SR/A card came out, Dolby offered the option of the CP65/222. The US list price for that unit was $6,250.00. You could still get what was called the CP65 but now renamed the CP65/350 and it carried a list price of $7,260.00 or nearlly $1000 more (list). How did Dolby lower the price? Simple, there was now just the Cat. 222SR/A doing the job of the three former cards of Cat 222, and two Cat. 350s.

As an upgrade, you don't get the cost savings since upon installing a Cat. 222SR/A you now have a Cat. 222 that you can only use as a spare or try to sell (with virtually no market).

The Cat. 300 is a single channel A and SR encoder and Decoder.

The Cat. 350 is a single channel SR only encoder/decoder.

The Cat. 450 is a single channel A only encoder/decoder.

There never was a "T" version of the Cat 300 series cards, only for the Cat. 280.

Logic would seem to suggest that the 222SR/A should be significantly cheaper to produce than the alternative three cards, and the prices you quote for the two versons of the processor seems to confirm thiis.

If Dolby were able to offer $1000 difference in the price of the processors, but only a small diifference in the price of the cards on their own, and the rest of the processor is the same, then it sounds like they are charging a greatly inflated price for the Cat. 222SR/A card.

I still like the '65, it's a nice processor.

You can't really equate things that easily. The Cat. 300 series of NR cards have application in all forms of NR, including recording studios, dubbers...you name it...in fact, they were not developed for Cinema, initially.

The Cat. 222SR/A has a much smaller market to choose from...just cinema and only from the low-end. As a result, it is a more expensive card to handle and support. Do I think the price is inflated on the CAt. 222SR/A? Sure, but that is business. They charged what they did because they could and many were sold to cinemas world-wide. I only fault them for pawning off a cascaded "S" circuit as "SR" when it doesn't measure nor sound like the real thing.
