Selecting the Effect Applied When Switching Buses (SD)
The effect applied when switching the video is selected by pressing
the TRANSITION buttons (SD).
Selecting the Bus Input
The video used on the A-BUS is selected by pressing the A-BUS
channel buttons (SD) 1–4. In the same manner, the video used on the
B-BUS is selected by pressing the B-BUS channel buttons (SD) 1–4.
When video is switched using the A-BUS channel buttons (SD)
or B-BUS channel buttons (SD), a period of time corresponding
to several frames is required to switch the video in each bus.
This is due to the time required to lock the video signals when
the formats for the video input in each channel are switched. To
reduce the length of time taken, adjust the following items from
the menu.
* When you want to switch channels rapidly, use the video

Depending on the settings for the following menu items,
noise may be generated when the video is switched. Set the
values to provide ample leeway to avoid this problem.

Keep the time setting somewhat short. The unit of time is the

As programmed at the factory, the V-440HD’s A-BUS channel
buttons (B-BUS channel buttons) light yellow for PGM output
and green for preview output. You can change these colors with
the “15. InputSw LED Color” setting under “13. SYSTEM” in
the menu.
Holding down one A-BUS channel button and pressing a
different A-BUS channel button switches the video for the
A-BUS channel button pressed second. When you release the
A-BUS channel button that was pressed second, the video for
the A-BUS channel button held down first is displayed. This
same function applies to the B-BUS channel buttons as well.
You can disable the operation of any desired button by setting
“6. SD Sw Enable” under “7. SD Input” in the menu.
