There are a number of factors to consider when determining where to set up the projector,
including the size and shape of your screen, the location of your power outlets, and the distance
between the projector and the rest of your equipment. But here are some general guidelines.

NOTE: To ensure adequate cable access, do not place the

projector within 6 inches (.15m) of a wall or other object.

Position the projector on a flat surface at a right angle to the screen.

The projector should be within 10 feet (3 m) of your power source and within 6 feet (1.8 m) of
your video source(s), unless good quality extension cables are to be used.

When installing the projector on the ceiling, refer to the installation guide that comes with the
Ceiling Mount Kit for more information. Knöll recommends use of an authorized Knöll CM25
ceiling mount. The addition of a CM20+6 extension bar lowers the projector 6” per bar as
required. The ceiling mount kit may be sold separately.

Position the projector the desired distance from the screen.

The projector must be at least 5.6 feet (1.7 m) from the projection screen.

The distance from the lens of the projector to the screen, the zoom setting, and the video format
determine the size of the
projected image.

Projector Positioning

The projected image becomes
larger as the distance between
the unit and screen increases.

The HD272 manual zoom allows
the distance from the screen to
be within a minimum and
maximum range. See the chart
on the next page for details. The
example on the right shows a
very large image 10’ high by
17.8’ wide. Note the bottom of
the image starts about 1.6’ above
the lens center with a horizontally
or flat mounted projector.
