Configuration and Operation
(continued)
Video Formats
The KD-VA5 supports only the following, most popular analog interlaced and progressive video
formats, like HDTV, NTSC, and PAL:
1080i (60 & 50 Hz)
720p (60 & 50 Hz)
480p (60 Hz)
576p (50 Hz)
576i (50 Hz, SCART only)
Auto Sensing
The KD-VA5 senses the appropriate Mode of operation, using Intelligent Auto Sensing ™ :
Component-to-RGBHV
Mode
If the Component Video input is connected with active
sync on Y, the Intelligent Auto Sensing
™ automatically forces
the KD-VA5 to the Component-to-RGBHV Video Mode by
sensing active sync on the “Y” Component Video signal.
RGBHV-to-Component
Mode
If there is no YPbPr input (in particular, no sync on the “Y”
channel), the unit automatically selects the RGBHV-to-
Component Video Mode.
See the Application Examples earlier in this Operating Manual. In each mode (RGBHV-to-
Component Video or Component-to-RGBHV Video) the corresponding Red LED should be lit.
Active sync on the “Y” Component Video input forces the KD-VA5 to operate in the Component-
to-RGBHV Video mode. To override this mode, you must turn off the Component Video source.
However, you may also need to disconnect the “Y” cable in some cases, in the event the
Component Video source continues to provide sync on the Y channel even when power is not
supplied to the Component Video source (this may happen in some instances with e.g. a Set
Top Box).

Slide Switch Sync Settings
Locate the block with the three (3) small Slide Switches labeled “1” “2” “3” on the side of the
unit, near the Pb Y Pr Input connector. The “Up” position is the “default” position (most typical
applications use these settings) that corresponds to the Green LEDs being lit on the face of the
unit. The “Down” position selects the corresponding Yellow LEDs active.

Switch 2 RGB Video Out: Sync is on the
Green channel (RGsB)
RGBHV Video Output, with separate
H & V sync
