C4 Series

  • The C4 Series carries a range of 3000 to 8000:1 contrast ratios, for vivid image quality and clear details on projected images.
  • Each projector is furnished with a low-maintenance, replaceable dust filter that effectively reduces smoke and dust from entering the projector. The cooling system is optimized for powerful heat dispersion, even at high altitudes.
  • Automatic or Manual Keystone correction makes sure that the projected image is ideal, despite projector placement. Automatic image reversal can be done without a menu setting when installed from the ceiling.
  • With a wired connection via RJ45, control or monitor all projectors through corresponding IP. Turn the projectors on/off, check configurations, view lamp times and operational status through the network.
  • The lamp cover is conveniently located on the top of the projector for easy replacement, even when the projector is installed on the ceiling.
  • Horizontal and vertical digital keystone correction fixes image distortion created when a projector’s lens is not perpendicular to the screen. Corner keystone correction allows the adjustment of all four angles of the image. These are ideal tools for when the projection environment is less than ideal.
  • The C4 Series projectors feature a 1.2x zoom lens for better image quality through the enlarged pixels. This allows the projector to be placed in various areas to meet installation requirements with the larger projected picture.
  • The edge-blending feature provides a seamless wide-screen presentation with multiple side-by-side projectors. Images can be perfectly matched for brightness and color correction.
