HT202 Throw Distance
hank you for choosing Knöll projectors! he H 202 projectors use digital light processing chips to give
bright clear images. heir lens allow for a limited amount of zooming (1:1.25). When ceiling mounting the
H 202 the Knöll CM23 mount kit is easy to install and swivels for exact placement. It drops the projector
about 3" and the projector lens is about 6" from the ceiling. If more of a drop is needed, the CM20+6 extender
adds an extra 6" drop. As many CM20+6 can be added as needed.
he most frequently asked questions concerning DLP projectors are:
How much can the projector be tilted up or down (when ceiling mounted or floor mounted)?
About 10 degrees. he H 202 projector features adjustable keystone. Ideally the projector should be as near
to level as possible with the screen drop as shown below.
Is the width of the 4:3 image the same as the 16:9 image?
Yes. When changing from a 4:3 to a 16:9 image the width stays the same, just the 16:9 image is on the 4:3
image with black rectangular boxes above and below the 16:9 image.
Projection throw distances are the maximum and minimum horizontal distances from the
projector lens to the screen. If the projector is mounted level (this is strongly
recommended) the image will drop (ceiling mounted projector) or rise (floor mounted
projector). he drop or rise is the vertical distance from the projector lens to the bottom
(floor mounted projector) of the image or the top (ceiling mounted projector) of the image.
