About your ABT-EM Trapdoor ElectriMask Electriscreen
Your ABT-EM ElectriMask Electriscreen offers the most technologically
advanced trapdoor roller screen in the world. The hingeless door is
powered by its own motor. Sound dampers ensure quiet operation.
The ElectriMask system is designed to integrate with the latest multi-format
video projectors, which are capable of variable sizes and aspect ratios for
viewing standard broadcast television and the wide format seen in
commercial theaters. The term aspect ratio refers to the format (width to
height) in which your home cinema sources are produced.
Your screen is equipped with either a vertical masking system to achieve a
16:9 aspect ratio (see Figure 1) or a horizontal masking system to achieve a
2.35:1 aspect ratio (see Figure 2).
