Author Topic: SR 70mm magnetic playback on CP 65 Fredrik A Thulin Film Handler Posts: 17 From: Gothenburg, västra götaland, sweden Registered: Oct 2015 posted 10-29-2015 12:20 PM                        hi everybody. I have just installed a pair of 70/35mm projectors at a new arthouse cinema. I am using a CP 65 for the magnetic sound, and a cat 222SR/A card with two cat 300 cards. The CP 65 are of a later date, all prepared for the cat 222 SR/A card. But how do I configure the processor so it can use the SR magnetic playback. Is there a manual for this somewhere?  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 10-29-2015 01:58 PM                     Have to point out that the cat 222 sr/a do not have the headroom in sr to handle magnetic tracts. The sr on those cards are sr lite.  |  IP: Logged Fredrik A Thulin Film Handler Posts: 17 From: Gothenburg, västra götaland, sweden Registered: Oct 2015 posted 10-29-2015 02:31 PM                        I was afraid of that. I am aware of the problems with cat 222 sr/a as it is not really dolby SR. How do you recommend that I proceed? A cp 200 and switch cards ? Or I could divert the audio signal through an SR A5 unit? But that would require som tinkering.  |  IP: Logged Sam D.

The CP200 with Cat. 280T's SR cards fitted is the ideal way. You could also use outboard SR in 363 frames and then into the CP65. They are fairly cheap on EBay.  |  IP: Logged Fredrik A Thulin Film Handler Posts: 17 From: Gothenburg, västra götaland, sweden Registered: Oct 2015 posted 10-29-2015 03:15 PM                        Would I benefit from installing an external cat 363 for the LE and RE screen channels also? Did any old 5 front prints use dolby A or even SR?  |  IP: Logged Sam D.
