About Manfrotto 851

Manfrotto's motorized EXPAN system is based on the well known manual EXPAN device, a fast and efficient paper background drive set designed to easily and rapidly roll and unroll all types of backgrounds (using a similar technique to that used on window blinds).

The 851 EXPAN background unit builds on the practicality of the original concept and adds motorized remote controlled practicality and ease of use to perfectly control the deployment of up to 10 backgrounds.

Remote controller and control box are both programmable for operation on one of seven different channels therefore if two control box systems are used in the same room, they can be set to different channels to avoid interference. In this case, it is not possible to control both main control boxes with one remote IR controller - Communication protocol IRUP Infra Red over UPSEC Protocol - Advanced IR receiver is very sensitive to remote controller signal but extremely disruption-proof.

Each channel has independent, programmable background stop levels for max and min extension positions. Positions are remembered even after power off. - Manual mode background positioning - Overload sensor automatically stops motor to protect equipment in case of overloading.

All backgrounds up function automatically rolls all backgrounds with a single touch of a button - Background Start-up function for easy background positioning in manual mode - Fast stop function stops the background immediately, also reduces motor inertia after power off - Advanced background rolling modes, which speed-up system operation i.e. rolling up unused backgrounds.
