Adjustments and settings for recording
Tape continuity with the user’s bit
Selecting REGEN for the UB MODE item on the <TC/UB>
screen by performing menu operations will call up the user’s
bit recorded on the tape, making it possible to continue
recording from that value. However, it is not possible to record
the contents that were set.
<Note>
The time code/user’s bit are also recorded in the VIDEO AUX
area of the unit’s memory. The time code (VITC) is the same
value as the sub code area’s time code (LTC).
Special information such as the camera’s frame rate is
recorded in the user’s bit (VITC’s user’s bit).
4-5 Setting the time data
The time code setting range extends from 00:00:00:00 to
23:59:59:29.
4-5-1 Setting the user’s bit
Memos and other information with up to 8 digits (dates, times)
in hexadecimal notation can be recorded on the sub code
track by setting the user’s bit.
1Set the DISPLAY switch to UB.
2Set the TCG switch to SET.
4Set the TCG switch to F-RUN or R-RUN.
5Open the <TC/UB> screen from the VTR MENU page
and select USER as the UB MODE item setting by
performing menu operations.
3Set the user’s bit using the SHIFT button, UP (+) button
and DOWN (–) button.
SHIFT button: This is used to cause the digit that is
to be set to flash. Each time it is
pressed, the flashing digit moves to
the right.
UP (+) button: This increments the numerical value
of the flashing digit by 1.
DOWN (–) button: This decrements the numerical value
of the flashing digit by 1.

CH3 and CH4 recording levels
When the unit is going to be used in the DVCPRO50 format,
audio signals can be recorded separately for four audio
channels. Perform menu operations to open the <MIC/
AUDIO1> screen from the VTR MENU page to change the
settings for the AUTO LEVEL CH3 and AUTO LEVEL CH4.
Depending on the setting conditions and input level for these
items, recording levels for audio tracks CH3 and CH4 change
as shown in the table below. Note that adjustments cannot be
performed manually.

<Note>
When the DVCPRO format (25 Mbps) has been set, the audio
signals will be recorded on two channels (CH1 and CH2) only.
The same signals as for CH1 and CH2 are also output to the
SDI output CH3 and CH4 channels.
