Equipment: Christie with FM35 Failsafe and 3Q automation. CAT-701 penthouse reader.Problem: Upon signalling end cue (outboard), the system randomly fails to properly switch to non-sync. Sometime it does. Initial observations: Upon receipt of the end cue, the system switched from Mode 10 (Digital) to Mode 05 (Stereo SR) and then switched back to Mode 10 again because of tail still in reader and reading good data. Tail falls through system and projector stops normally, but processor stays in Mode 05. Upon either pressing the end feature console button or flashing a piece of cue tape in front of the reader, the system pulses fine over to Mode 60 (Non-Sync). I am thinking of adding a second end show piece of tape closer to the end of the tail but wanted your thoughts. Thanks Paul

Hi Paul Have you tryed cleaning the cue detectors??? I know in the past the detectors can get very dirty and are often ignored on the daily cleaning of the Projectors, after that replace the cue. Adding another cue dosen't work ,also make sure the cue is long enoght some times I have seen the LED light up but not trigger the relay becase the signal was not long enoght.------------------

I don't think it has to do with dirty detectors as it doesn't use any visible or led light to detect the foil.I have tried using a full length cue instead of a single frame thinking that the pulse wasn't long enough and that didn't help either. Scott, no the processors are not stacked at the theatre, either Dolby or DTS but not both. Brad, if it was a source, wouldn't there be a 's' in the display indicating that. I will check though. Thanks to all, even you Bill.

Another cause for this on some processors is the fact that when the change over closes and pulses the processor to format 60 (non-sync), the films with dolby digital and sdds have code until just befor tail out, so whats happening is the processor gets the non sync pulse, then the digital processor says ummm no, theres still code, and then pulses back into 10 until it loses code then reverts to 05. If it does this with the dolby digital unit, then simply wire the plug where the cat 700 or 701 plugs in to go dead when the change over closes, if its the older sdds processor, this is normal, although neither usually do it on the 500.

If you are running v1.61 on your CP-500 then this is a "known" bug...I have confirmed in on different CP-500s using completely different automations. A quick "downgrade" to V1.5 or the preferred 1.31 will make your problem go away. If you are using surround-EX you will need to say with the last version of 1.5 ( I think it is 1.52 or 1.51) Steve ------------------ "Old projectionists never die, they just changeover!"
