Audio insert editing function with 23.98 Hz VTR system and 30 Hz
external operating environments
As shown in the above diagram of the system connections, this function enables audio insert editing on the
23.98P tape of the model HD3700B even in an environment with a 30 Hz external device, and by so doing, the
efficiency of the editing work is improved.
Refer to the information provided later for details on the VTR menu settings.
OEditing accuracyN
With the model HD3700B, the IN/OUT point accuracy falls into one of the following three patterns since the
signals are recorded with the video and input audio phases aligned (there is no misalignment between the
audio and video phases) on the tape. (Bear in mind that, as shown in patterns 2 and 3, the IN and/or OUT
points may shift.)
