Section 4— Switcher Operations
Effects Send Operations (Option)
The Effects Send option (purchased separately) allows video/key
signals in an M/E to be routed outside the switcher for processing
by an external device such as a DPM (Digital Picture
Manipulator), and then brought back into the same crosspoint
(Looping mode), or another crosspoint (Non-Looping mode) for
mixing and output. The switcher Aux Buses are used to output the
video/key signals to the external device.
There are two ways to use Effects Send: Looping Mode and Non-
Looping Mode. Both methods are described and demonstrated
below. Refer to your
Operator’s Reference , Section 2, Preview/
Aux Bus Source Select and Delegate Subpanel , for more
information.
NOTE: The ‘A’ and ‘B’ Keyers ( BKGD A and BKGD B buttons selected
on the Keyer Subpanel) are only available for Effects Send when the
M/E is in Layered Mode.
