HT200 and HT210 Throw Distance
Thank you for choosing Knöll projectors! The HT200 and HT210 projectors use digital light processing chips
to give bright clear images. Their lens allow for a limited amount of zooming. If a longer or shorter throw
than the projector zoom limits allow is required a telephoto 1.6 times and wideangle 0.78 x lens can be
ordered.
When ceiling mounting the HT200 or HT210 the Knöll C 20 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 C 20+6 extender adds an extra 6" drop. As many C 20+6 can be added as needed.
The most frequently asked questions concerning DLP projectors are:
How much can the projector be tilted down (when ceiling mounting) or up (when floor mounted)?
Almost none. The HT200 and HT210 do not have adjustable keystone, so for best overall use, the projector
should ideally be level if the screen is vertical (which is usually the case).
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). The 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.
