7th Step: Effects Configuration
DVE Configuration
The DVE option allows one background bus (audio and video) and its
selected upstream keys to be in a squeeze window with another back-
ground bus and its selected upstream keys serving as the background. The
Aux bus is utilized with DVE for selecting the second source.
A DVE effect is entered by selecting the preferred effect and pressing Take .
While the DVE effect is active, a variety of audio/video transitions may be
performed (also by pressing
Take ). A DVE effect is exited by selecting one
of the available exit modes and pressing Take .
When a DVE effect is active, the content of the squeeze window is the Pgm
bus. The content of the background is the Aux bus. An example of this
effect is shown in
Figure 139 .

Transition type (cut, fade, or wipe) and transition speed are selected using
the control panel. Transitions to DVE effects and exits from DVE effects take
place at the selected rate and type.
The DVE hardware consists of a mezzanine board that mounts on the main
processor board (see
Figure 140 ), and, in some cases, an AES-to-MADI con-
verter.
Note If the optional DVE mezzanine board is not installed, DVE effects are not avail-
able in Maestro. An optional DVE mezzanine board must be installed on each
channel (Maestro processor) on which DVE is desirable.
