CRYSTAL 4SH 25-28
The reference in the home theater
Crystal 4SH 25-28 is the the reference in the home theater market thanks to new high-precision lens, latest laser-hybrid light source and a perfect HDR image management. Crystal 4SH 25-28 is the best choice for living room, multipurpose room, and medium or large Home Cinema.
Crystal 4 SH 25-28 sports a perfect white point color and an expanded color space, achieving the DCI standard.
Crystal 4 SH 25-28 presents an elegant and minimalist crystal glass-based cabinet for a sleek look when installed in the ceiling or over a bookshelf or furniture.
Crystal 4 SH 25-28 comes in either a white or black glass finish, in order to easily fit with modern or classic environments. An invisible crystal glass back door hides all the inputs, cables, and connectors.
Excellent colorimetry
The brightness of Crystal 4SH 25-28 is extremely performant: 3.800 lumens.
Crystal 4 Sh 25-28 comes with the LCC 4.0 (Live Color Calibration), a special PC software developed by SIM2 that allows accurate automatic color calibration.
Brightness is the key factor in experiencing all the benefits of the HDR processing in image quality
That said, brightness without dynamics and proper management is not enough to create an extraordinary picture. HDR processing is THE real revolution in video imaging and home cinema performance. The result of this accurate HDR processing is to make visible all image details either in the dark and/or bright parts of the image: an impressive cinematic achievement and quite an experience!
The Crystal 4 Sh 25-28 uses 2 color wheels: one with phosphors and one with dichroic filters. The first with its latest generation green and yellow phosphors offers constant emissions over time and as the temperature changes. The second purifies the colors, with which SIM2, with its long experience in the field of colorimetric reproduction, has reached an unusual degree of colorimetric reproduction accuracy in the Crystal 4 SH 25-28.
Perfect HDR
SIM2 is the company with one of the longest and most qualified experiences in the field of HDR, both in flat monitors and in video projection, having started to work on HDR more than 13 years ago.
HDR processing is THE real revolution in video imaging and home cinema performance.
