The Source Selection Bus allows you to choose the sources that are routed into PIPs and
keys. Please note:
• Use the SHIFT button to access sources 9 through 16.
• The SDI 1 and SDI 2 buttons are only active when a ScreenPRO-II is configured
to use
internal routing. The buttons are disabled when external routing is used.
 Use the following steps to switch sources into a PIP or a Key:
1. Press LAYER A or LAYER B in the Layer Control Section. Note:
~ The button blinks to indicate that it is available for modification.
~ The associated layer’s raster box blinks on Preview.
~ If a PIP or Key is assigned to the layer, its source can now be changed.
2. Press the desired button on the Source Selection Bus to assign that source to
the PIP or Key. The button blinks to indicate that it is active for modification.
Please note the following important points regarding sources:
• When the Red LED above a source button is lit, the source is on Program —
provided that its associated Destination button is active.
• When a source button is lit solid, the source is on Preview — but it is not active for
manipulation. Only blinking source buttons are active for modification.
• When the Red LED above a source button is blinking, the mixer is set to Mix
Mode
(the Split button is off). The blinking Red LED indicates the layer that is on
Program, and the
alternate layer is enabled for modification.
• Multiple sources can appear on Program and Preview simultaneously, but only
one button can be blinking and active for modification on Preview.
