The buttons labeled ZOOM 1-4 select one of the first four Zoom Presets for the currently delegated M/Es. Add
the SHIFT button to access presets 5-8. The ANIM ZOOM button toggles the CUT (Duration) option for
delegated M/Es. When ANIM ZOOM is enabled, pressing an unselected zoom preset button initiates a smooth
zoom from the current level to the new level. Preset selection applies directly to all delegated M/Es.
If you push a zoom preset button a second time at any point, the animated zoom will ease-out and stop. Press
it again to re-commence the zoom and complete it.
The duration of animated zooms is determined by the ZOOM RATE setting. Rotate the knob to modify the
duration of the effect, or push it to jump to a preset duration (Slow, Medium or Fast).

P OSITIONER D ELEGATE
The Positioner section allows you to adjust position attributes for different overlays and video layers using
the Joystick. The DELEGATE group includes seven buttons. In some cases, the scope of application for a
DELEGATE selection is further modified by button selections in other sections of the control surface.
For example:
 The M/E A and B buttons delegate Joystick operations to Input A and Input B of the M/Es currently
selected in the M/E DELEGATE group.
 Similarly, the M/E KEY button assigns the Joystick to control position attributes for the KEY layer of
currently delegated M/Es.
 Again, selecting VIRTUAL ZOOM tells the Joystick to control the zoom level of the currently delegated
M/Es. The joystick mode buttons (such as POS/SCALE, discussed shortly) are not lit when the
POSITIONER DELEGATE selection is VIRTUAL ZOOM.
Use the joystick to control Virtual Zoom as follows:
