12-volt DC output

The 3.5mm mini-jack trigger provides a 12-volt, 0.25 amp DC output. It provides a constant output while the projector is on. It has numerous uses. For example, if you connect your projection screen to the 12-volt DC output with the cable that came with your screen, when you turn on the projector the screen will move down; when you turn the projector off, the screen will return to the storage position.

Setting up the Projector

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 (0.15 m) of a wall or other object.

Position the projector on a flat surface (either on a table or ceiling mounted) 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 or baluns 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. Knoll recommends use of the mount shipped with the projector or the deluxe swivel Knoll CM26 ceiling mount. The addition of a CM20+6 extension bar lowers the projector 6” per bar as required. The CM25EX is an adjustable extender that can lower the projector 6.75” to 11” (17-28 cm). The ceiling mount kit may be sold separately.
