Recording Format and Input/Output Signals
(This unit and other equipment for professional use may be functionally extended. For details, see the notes below
the table.)
1) The unit cannot record 4-channel sound in HDV format.
2) There are two modes for audio signal recording: Lock mode and Unlock mode. In Lock mode, the sampling frequencies of
audio and video are synchronized. In Unlock mode, adopted by the consumer DV format, the two sampling frequencies are
independent. Lock mode maintains high compatibility with higher formats and offers better digital processing and smoother
transition than Unlock mode when you edit audio.
3) The unit cannot record in DV format with 16 bit: 32 kHz or 44.1 kHz.
4) The unit has been functionally extended with a function for switching between Lock mode and Unlock mode.
5) The unit has been functionally extended with a function to enable selecting DF/NDF for 60i (including 24p and 30p) with
HDV or DV (SP) format.
6) The unit is not equipped with user bit setting function.
