System switching
z Some of the system menu and setup menu items each have
different settings for different operation modes [59/60 Hz, 50 Hz,
23/24 Hz, 25 Hz (HD or SD) and 50 Hz (HD or SD)]. These
settings are saved separately.
(This concerns those items whose settings were described for
each operation mode on the system menu and setup menu
tables.)
z For further details, refer to <Menu management accompanying
switching the system frequency> on page 113.
z Since this VTR becomes a playback-only unit when the 23/24
Hz, 25 Hz (HD or SD) or 50 Hz (HD or SD) mode has been
selected, the functions relating to EE, recording and editing
are all set to the inhibited status. Neither is it possible to
select CTL in such a case.
(The related menus and function buttons are not displayed,
and operation is prohibited.)
For the instant when the tape begins to run at the 1k speed
such as when it starts playing from the STOP status, the
image is disrupted and the sound is muted for several
frames because the tape is being synchronized with the REF
input.
The underlining (__) denotes the factory setting mode.

AV PHASE
For adjusting the phase of the AUDIO output
with the VIDEO output
20.8 microsecond steps
The phase of audio output advances with
respect to image output.
The phase of audio output delays with
respect to image output.

SYSTEM
FREQ*
1
For selecting the system frequency.
0000 59/60
The 59.94 Hz or 60 Hz system frequency is
selected.
0001 50i/25P*
2
The 50 Hz or 25 PsF system frequency is
selected.
At this setting, the 1080/25 PsF format signals
can be recorded and played back in the same
way as with the 1080/50i format.
0002 23/24
The 23.98 Hz or 24 Hz system frequency is
selected.
0003 25(HD)
The 25 Hz system frequency is selected.
However, SD SDI output and analog composite
output are delayed with respect to HD SDI output
by about one field.
0004 25(SD)
The 25 Hz system frequency is selected.
However, the black signal is output from HD SDI
output.
0005 50(HD)
The 50 Hz system frequency is selected.
However, SD SDI output and analog composite
output are delayed with respect to HD SDI output
by about one field.
0006 50(SD)
The 50 Hz system frequency is selected.
However, the black signal is output from HD SDI
output.
59/60Hz mode A state selecting 0 (59/60)
50Hz mode A state selecting 1 (50i/25P)
23/24Hz mode A state selecting 2 (23/24)
25Hz(HD) mode A state selecting 3 (25 (HD))
25Hz(SD) mode A state selecting 4 (25 (SD))
50Hz(HD) mode A state selecting 5 (50 (HD))
50Hz(SD) mode A state selecting 6 (50 (SD))

HD SYS H ADV
For selecting the output whose HD output
phase is to be advanced by 90H in relation to
the SD output.
0000 0H
Both the HD and SD signals are output in phase
with the HD and SD REF output signals.
0001 90H
The HD signals are output at a phase advanced
by 90H from the SD output signals.
When the SD REF signal is input, the REF input
and SD output are in-phase, and when the HD
REF signal is input, the REF input and HD output
are inphase.
<Notes>
z The audio signals and TC signal are output in
phase with the HD output.
z With the 720p format, there is a phase difference
of 120H between them.

MENU LOCK
For selecting whether to set or release the
system file lock mode.
0000 OFF
Lock released (changes enabled)
0001 ON
Lock set (changes prohibited)
<Notes>
Even if [ON] is selected, the file is overwritten when
the system file is retrieved from an SD memory
card.
