Specifying a Reference Clock
You can specify a clock to which operation of the V-800HD MK II is
referenced (a reference clock).
NOTE
Video output from the SD OUT connector is referenced to the
V-800HD MK II’s internal clock irrespective of the reference-clock
setting.
1.
Select the [MENU] button
g
“System”
g
“Reference.”
2.
Use the [VALUE] knob to specify the reference clock.
Value
Explanation
Internal
The V-800HD MK II’s internal clock is used as the reference
clock.
External
A synchronizing signal input via the REFERENCE IN
connector is used as the reference clock.
Black-burst (frame synchronization), bi-level, and tri-level
synchronizing signals are supported.
Input SDI 1–4
A signal input via one of the SDI IN 1–4 connectors is
used as the reference clock.
The VSYNC (vertical synchronizing) signal output from
the V-800HD MK II is synchronized to the VSYNC signal
input via SDI.

When Set to “External” or “Input SDI 1–4”
Adjust the following System menu items as needed.
MENU item
Explanation
Clock Adjust
This adjusts the phase horizontally.
Adjust this when output is horizontally out of sync with
the operation of other devices using the same clock.
Line Adjust
This adjusts the phase vertically.
Adjust this when output is vertically out of sync with or
field-shifted from the operation of other devices using
the same clock.
Field Sync
Processing
This is a feature that automatically aligns the fields in
interlaced input and output.
Setting this to “ON” lengthens processing time between
video input and output, but the fields are automatically
synchronized.
3.
Press the [MENU] button to quit the menu.
MEMO
You can use the REFERENCE indicator to check the status of
synchronization.
INTERNAL
This lights up when synchronized to the V-800HD MK II’s
internal clock.
EXTERNAL
This lights up when synchronized to an external source.
It flashes when synchronization to an external source is not
in effect.
