7 CHROMA (chrominance) PHASE knob and
PRESET/MANUAL switch
The switch makes the selection described immediately
below. When it is set to MANUAL, you can use the
knob to adjust the chrominance phase (the phase
difference from a burst signal).
8 SYNC knob
This adjusts the output signal sync phase with respect
to the input reference signal to this unit, in a range of
±15 µs.
Use this adjustment when the output phase of this unit
is not accurately aligned with the reference signal
phase, or when carrying out special effects editing with
this unit and other VTRs connected to a switcher or
other equipment.
9 SC (subcarrier) knob
This adjusts the output signal subcarrier phase with
respect to the input reference signal to this unit, in a
range of ±200 ns.
For playback of composite signals, use this adjustment
when the output phase of this unit with respect to the
phase of the reference signal is not accurately aligned
with the subcarrier phase. This adjustment does not
affect the output SCH (subcarrier - sync) phase, which
remains constant.
!º GOOD SHOT switch
When this switch is in the REC INHIBIT position, the
GOOD SHOT REC INHIBIT indicator in the lower
