C12 : REC CH CONDITION
In this menu, the error condition for each channel is displayed in three steps (GRN, YEL, and RED) when
the tape recorded based on a Betacam SX format is played back using the advance PB heads (A1, A2, B1,
and B2) by tracking in the insert REC mode, and played back using the confidence PB heads (A3 and B3)
in the crash REC mode.
C12 checks using the PB signal from the PB heads (A1, A2, A3, B1, B2, and B3) in the REC mode.
m
.
Display the channel condition of the A3 and B3 heads in the CH CONDITION area on the sub LCD
display when selecting the CONFIDENCE PB MODE to ON in the crash REC mode.
. During normal operation, the tape is played back by non-tracking. Therefore, the condition for each
channel cannot be confirmed using a CH CONDITION indicator.
. If abnormality exists in the servo system of a VTR, each menu of C1 : RF CHECK does not function
normally.
