WolfVision VZ-C12 User Manual - Handbuch (Seite 8)

Use the calculation program on WolfVision's internet homepage to calculate the exact
position and image sizes :
The distance is measured from
the bottom of the Ceiling
Visualizer to the working
surface. These figures may
vary a little in reality, because
the position of the focus
influences the size. Masking of
the monitor or projector should
also be taken into
consideration (i.e. some units
cut off the edges of the picture).
Theoretically larger distances
than 4000mm (approx. 160")
are possible, but the pick-up
size would be too large and the
light output too low.
Please read first the Installation Manual before fixing the assembly to the room ceiling.
The size of the smallest and largest image that the unit can pick up is not fixed. It depends
on the distance between the working surface and the bottom of the Visualizer. The tables in
the installation manual show the relationship between mounting height and pick-up sizes:

In extremely high rooms the smallest image the unit can pick-up may not be small enough.
In such cases a standard ceiling mount or projector-lift can be used to suspend the Ceiling
Visualizer further from the ceiling.
Before deinstallation the
unit please read first the
Installation Manual!
