One method to determine the correct system timing phase is to select a
source on the AUX1 bus and then adjust the switcher’s phase to center the
source in the timing window. Record this phase setting. Repeat this process
for all external video sources.
Note Internal video sources cannot be measured and do not show up in the mea-
surement window when selected.
Find the average Phase value by adding the highest and lowest Phase
numbers together and then divide by two. Now recheck all sources with
the new average Phase number. Fine tune the
Phase adjustment if neces-
sary.
There may be some sources that still do not fall within the legal timing
window. For these sources you will have to go back to the video source
itself and change its timing with respect to reference until it appears within
the legal timing window.
To adjust the Internal System Timing on the Kayenne XL:
1.
Observe the vertical black cursor in the timing window to see how the
source you have selected compares with the internal system timing.
2.
Now adjust the internal system timing by physically turning Genlock
Phase . This adjusts the switcher sync in relation to the Reference you
have selected.
3. Turn the Genlock Phase to position the vertical black cursor as close as
possible to the middle of the green legal timing window. The vertical
black cursor must be in the green and not moving.
4. Position the black cursor (representing the timing for the video source
you have selected for AUX 1) near the center of the legal timing
window. Green indicates that the source is within legal timing and
yellow means that the source is outside legal timing window limits.
5.
Write down the Phase number for each source to help determine the
average Phase number for all sources.
6.
Once you have checked the timing for the first video source you
selected from the AUX1 bus, you must repeat the process for every
other video source on the AUX1 bus. Select all video sources and record
their Phase number.
7.
Find the average Phase value by adding the highest and the lower
Phase numbers together and then divide by two.
8.
Now set the Phase as close as possible to the average number.
9. Recheck all video sources on AUX1 for timing. Fine tune the Phase
adjustments if necessary.
