Setting gain and black level

Press F2 from the home menu to display the top Level menu providing the following
functions:

•

 

Luminance gain and black level

•

 

Chrominance gain

The gain and offset adjustments are independent for Composite and Y/C modes. For
example, if the unit is set up in composite mode and subsequently adjusted in Y/C mode,
the composite adjustments are maintained and will be restored when composite operation
is resumed.

There are two sets of independent gain and offset adjustments; composite and Y/C.

 Level menu structure

Description

Use F1 to select Luminance menu and F3 to select
Chrominance menu

F1 allows ADJ shaft encoder to set luminance gain
F3 allows ADJ shaft encoder to set offset (black level)
CAL sets gain and black level to unity values

F1 allows ADJ shaft encoder to set chroma gain
CAL sets chroma gain to unity value

Note:

The displayed number varies as the shaft encoder is rotated to give an indication of the
setting relative to the factory default

Setting luminance gain and black level

Select the 'LUMA' menu to allow the luminance gain and offset (black level) for the
current mode to be adjusted.

Press the 'F1' button to allow the shaft encoder to adjust the luminance gain. The shaft
encoder LED will illuminate and an asterisk will appear on the display next to 'Y GAIN'.
Use the shaft encoder to adjust the luminance gain from 0 to 200%.

Press the 'F3' button to allow the shaft encoder to adjust the black level. The shaft encoder
LED will illuminate and an asterisk will appear on the display next to 'Y OFFSET'. Use
the shaft encoder to adjust the black level from –30 to +385mV.

Press the 'CAL' button at any time while in this menu to set gain and offset to their default
values (100% and 0mV).
