WolfVision VZ-C32 Installation - Handbuch (Seite 5)

A difference between Ceiling- and "Desktop-"Visualizers is that the size of the smallest and
largest image the unit can pick up is not fixed. This depends on how high above the working
surface the Visualizer is mounted. It is very important to know which image sizes you would
like to pick up with the Ceiling Visualizer before installing the unit, in order to decide in
which distance to the working surface the Ceiling Visualizer will be mounted to the ceiling.
The relationship between the mounting height and image sizes can be checked with the
calculation program on WolfVision's homepage (see below).
The following table shows the distance which
is called "x" in the illustration on the right side:

x mm = distance * tan 18° - 291mm
x" = distance * tan 18° - 11.45"
(tan 18° = 0.3249)
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.
IMPORTANT:
The center of the image is offset 87.5 mm (3.5 ")
to the right, from the middle of the Visualizer
housing !
