You could hoop up an SRA-5 box or do some creative wiring to the Aux rack (provided you have one) to run 35mm in A or SR without swapping cards, but 70mm would require the swapping.

Here is another solution with a cp200 and it would require 3 or the SMART SR1+ adapters and the DOLBY 280T cards
Connect the outputs of the MPU to both the L prein and the Laux in terminals and the same for right channel.
Set the aux pots to max
by grounding the SR enable line with a new format number you would pass the signal through the 280T cards ( the new format would have to turn the 22's off)
If the SR enable is left high the cards are bypassed for regular A type

Okay, here's a related question, this coming from someone that's just gotten a CP-200 and has not before had any sound processing equipment (Hence, all these Cat #'s have been pretty meaningless to me at this point.). Brad recommended the 280T SR cards for the CP-200. Well, I was able to get some 350's on the very cheap (although I had ordered through a friend some 280s). Will they not work with the CP-200? I can't say that I've even tried to install them yet. If not, anyone care to trade for some 280T's?

Bump.

Do _all_ CP65s accept the cat. 222 "SR"/A card or will it work only in newer models (built after the 222 "SR"/A card was designed)?

I'll be doing a show in a couple of weeks in a venue which is equipped with a CP65 that is set up for mono and A-type NR (with cat. 222) only. Since the film will be SR, can I just take the evil cat. 222 "SR"/A card out of my CP65 at home and bring it to the venue and expect it to work? Even though the sound will be mono, I would at least like to make sure that it sounds as good as it possibly can.

Scott, the older CP-65 processors need to be modified to work with the Cat. 222 SR/A. From memory I think it's a small extra card that's mounted on the backplane. The CP-65 will then work with Cat. 350s + a Cat. 222, or a Cat 222 SR/A. If both Cat. 350s and a Cat. 222 SR/A are fitted, then the Cat. 350s will be used for SR; if you remove them, then the unit will revert to using the Cat. 222 SR/A for SR.

Full details are in the Cat. 222 SR/A manual, available in the Film-Tech manuals section.

Ahh..thanks. It didn't occur to me that there would be a whole manual just for the card. Hopefully the CP65 in question has a "REV 3" backplane (post-s/n 504989) and will take the fake-SR card without modification (which I am not going to do for a one-off show).

Otherwise, the director of a Big Upcoming Pixar Film will just have to deal with hearing his film played with the wrong NR.

Scott, II don't know what would happen if you tried to use a Cat. 222 SR/A in a processor that hadn't been modiified.

I've only just got in from doing some progection this evening, after my daytime job, 14 hours total, I had to work late Monday and yesterday, 12 hours each. At the weekend I'm doing something qute insane; I'm flying over there on Saturday morning, and then flying back on Sunday evening, landing at London Gatwick at about 8:30 on Monday, then going in to work, 12 hour shifts on both Monday and Tuesday. I can't keep doing this at my age! I'll only be back for about two weeks, then I'm flying over there again.

I've got some more projection work lined up for November - February.

It's midnght, I'm going to bed, got to be up early n the morning.
