Controlling The Aspect Ratio Of The Box; Centring The Box On The Raster; Controlling The Box White Level; Controlling The Box Size - evertz 9590 Instruction Manual

4.7.2. Controlling the Aspect Ratio of the Box

Auto Aspect ratio Off
The AUTO ASPECT button is used to control the aspect ratio of the mask, the boxes and the circle
objects, and whether they are centred or not. The auto aspect ratio mode forces the box objects to be
centred and their size to follow one of the following fixed aspect ratios: 1:1, 4:3(1.33), 14:9 (1.55), 16:9
(1.78), 1.67, 1.85, 2.35. When the auto aspect ratio mode is set to Off the box dimensions are not
constrained to follow a fixed aspect ratio and the setup menu force centre item determines whether they
will be forced to the centre of the raster. See section 4.3.1 for more information about auto aspect ratio
mode.

4.7.3. Centring the Box on the Raster

When auto aspect ratio mode is On the boxes will always be centred on the raster. When auto aspect
ratio mode is Off the SETUP menu item force centre controls whether the boxes will be centred or not (see
section 4.2.9.) When the force centre item is Off it is possible to independently position and size the whole
box, using the SIZE and POS buttons and turning one of the shaft encoders as outlined in the following
sections.

4.7.4. Controlling the Box White Level

Press the LEVEL button to adjust the box white level. The white level can be adjusted in the range of "0"
through "14", in single digit increments, using either shaft encoder with "0" corresponding to "black" and
"14" corresponding to "white".

4.7.5. Controlling the Box Size

Press the SIZE button, when the box its button is blinking, to adjust the box size. The size of the box can
be adjusted in one of four modes, depending on the setting of the Setup menu Force Centre item and the
Auto aspect ratio mode. The remote panel display will show the box size while the SIZE button is brightly
illuminated. The size adjust function will be deselected after 3 minutes of panel activity, or when the
another button is pressed.
