WolfVision VZ-C32 3 User Manual - Handbuch (Seite 8)

Use the calculation program on WolfVision's internet homepage to calculate the exact position and image
sizes:
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 5000mm (approx. 196") are possible, but the pick-up size
would be too large and the light output too low.

Audience
Please read first the Installation Manual before fixing the assembly to the ceiling.
The size of the smallest and largest image that the unit can pick up is not fixed. This is depending on the
distance between the working surface and the bottom of the Visualizer. The tables in the installation manual
show the pick-up sizes in relation to the mounting height:
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.
