7.6.1 GENLOCK ADJUSTMENT
The mixers include the possibility to perform the genlock adjustment of the individ-
ual input sources in Install E-Box menu.
When adjusting the genlock phase, all sources have to be successively checked
for their timing by switching up on the bus Aux1. To adjust the genlock phase, select
the softkey in the Install E-Box menu and select the index card Timing. The follow-
ing display is represented:
With Genlock Phase, the phase relation of the mixer can be shifted +12/-12 lines
in comparison with the genlock reference signal.
The display TIMING serves for checking the timing of the sources.
The bar diagram displays the timing of the source to the mixer that is selected on
bus Aux1.
The display can give the following informations:
Aux1: Shows the selected source on the Aux1 Bus witch is used
for timing measurement.
Vert: Shows how many lines the source is off in comparison
to the switcher timing.
Hor: Shows how many us the source is off in comparison
to the switcher timing (only if Vert=0).
External Reference:
Shows the standard of the external reference signal
at the genlock input.
The bar diagram shows the timing of the input source relatively to the autophasing
range. All sources should be timed between the two marker lines in the middle area
of the bar. The right line (with the respective switcher type name) marks the earliest
mixer input (latest timing of the sources).
