Reader Delay Setting
This reader uses the same delay setting as the Dolby
perforation. There are a number of methods to set the delay: a dedicated sync loop,
the SR.D Jiffy test film and setup menu in the CP500 and CP650.
Installing the Video Cable and Flywheel
Note: Turn off Dolby processor power before attaching
cable to reader or cinema processor. Do not hot-plug
this cable as you may destroy the reader CCD card,
Dolby video board, or both.
Run the video cable through the hole provided in the back of the reader and plug
it into the CCD board connector. A separate ground lug is provided to bond the
cable to the reader chassis. Tighten wire clamp around the cable. Plug the other
end of cable into the Dolby processor.
Please confirm the cable is plugged into reader
connector, pin for pin. Misaligned pins will cause
damage to sensor board or Dolby Processor.
Remove the protective boot from sound drum shaft and attach flywheel taking care
to line up the set screw with the slot in the Sound Drum Shaft. Be careful not to
lose the thrust spring.
Replace the back cover. Restore AC power to Dolby processor.
Thread and run a film loop or reel with a Dolby
error rate displayed on the Dolby
previews typically run at error rates 3 and below. The video status light should go
green with film is running. This indicates an adequate video level (2 Volts or more)
for correct operation. The light will turn red for a number of reasons including low
LED output or a dirty lens.
The alignment of the reader is set at the factory and should not require further
adjustment.
Reader video alignment can be checked if necessary using the instruction below.
