Digital Projection POWER 2v, Руководство пользователя

Страница: 30 / 174

For optimum viewing, the screen should be a flat surface perpendicular to the floor.
The bottom of the screen should be 1.2m (4 feet) above the floor and the front row
of the audience should not have to look up more than 30° to see the top of the
screen (see opposite).
The distance between the front row of the audience and the screen should be at least
twice the screen height and the distance between the back row and the screen should
be a maximum of 8 times the screen height. The screen viewing area should be
within a 60° range from the face of the screen.
If you intend to use a rear projection screen you must ensure you have sufficient
distance behind the screen for the projector to be correctly located (see B—4). Rear
projection has the advantage that the projector cannot be seen and higher ambient
light levels can be tolerated. Although the image can be flipped to rear projection
using the Image Mode Menu (see system operation, C—28) and displayed without
the need for extra mirrors or equipment, it makes the installation more complicated
and advice should be sought from your local dealer before attempting an installation
in this way.
