Bi Phase Generator FDL 60




Status: Optional

Purpose: To provide 100% accurate 240Hz bi phase.
 
 

An External 240 Hz Bi-phase tach generator may be installed into the FDL 60. To provide 100% accurate 240Hz bi phase in all mode of operation. This outputs 240Hz-10 pulse per frame in 35mm film only! In 16mm the output is 5 pulse per frame. In most Evertz Time code units this is not a problem. Most Evertz units can be set to 5 pulse per frame, software updates for this setting may be avlible. (If you need only 16mm to be 240Hz/10pulse per frame substitute the 40 in the part numbers to 80. Then 16mm will be correct and not 35mm.)
