Menu 300 is used to set the Biphase Frame Rate. In most applications in the USA the film frame rate will
be set to 24 fps (the default setting). For some European applications this may need to be set for 25 fps,
and for specialized film for video applications there is also the 30 fps rate available.
Menu 301is used to set the Biphase Pulse Rate. The number of pulses per frame is determined by the model
of film transport or dubber that is being used with the MMR-8. See Table 5.1 for a list of transport types
and the pulses per frame they use. If the model that will be connected to the MMR-8 is not listed consult the
film transport manual for the specification. It is normally listed under the specifications as the ppf for
nominal play speed. If this setting is incorrect then all time code and feet & frame calculations made by the
MMR-8 will be off since they are derived from the pulse rate.
Menu 302 is used to choose the Biphase I/O setting. In the majority of applications biphase control will
be used so Menu 302 is normally left at the default setting of biphase.
Menu 320is used to set the Biphase acceleration. Normally this setting does not need to be changed since
it will be set automatically according to the pulse rate setting in Menu 301. If it does need to be changed
do so only after Menu 301 is set.
Menu 321is used to set the maximum Biphase wind speed. This setting is also automatically changed
according to the pulse rate setting in Menu 301. In most cases this will only need to be changed if you are
dealing with fragile film stock or if it is desired to slow wind the film when changing reels.
