SI’s new Zero-G offers an “extended maximum drop” to solve the problem that integrators often have when specifying a motorized screen where extremely tall ceilings make it all but impossible. Zero-G has no black mask above the viewing surface. Instead, the Zero-G screen is housed in a two-piece tube that is suspended from Ultra-High Molecular Weight Polyethylene (UHMwPE) cables, where it deploys at a pre-set location and unrolls itself, displaying the viewing surface with up to 15.8-feet of drop.
SI’s ambient light rejecting (ALR) screen materials such as Slate, which are also available on Zero-G. An added benefit is that the area above the Zero-G viewing surface is acoustically transparent and does not negatively impact the viewing experience like a standard motorized screen with black masking material would. Because it’s completely open above, art-deco walls, large windows like what you will find in a house of worship, speakers or even lighting systems all remain visible, not covered by a large black mask such as you would find in traditional motorized screen systems.
In addition to the newly added long drop option, SI says it has also re-engineered many of the internals of the Zero-G chassis including mechanics such as a new end-cap design that is milled entirely from one block of aluminum and improved consistencies for internal mounting points by using barrel mounts instead of a pulley system.
