Lumagen Radiance Pro UltraHD Series

Lumagen Radiance Pro processing power, SD - Ultra HD in and out, 17x17x17 CMS, DARBEE DVP

This series of video processors enhances the award-winning family by adding support for 4k60 inputs and outputs, including HDCP 2.2. Winner of a CEPro Best of 2015 award, the RadiancePro offers up to eight inputs, and four outputs, plus a multitude of essential setup and calibration features. More than just an HDMI switcher, the Pro is considered by many experts to be an essential part of any quality home theatre.

Scaling quality again comes to the forefront with the advent of 4k projectors and televisions. Lumagen’s NoRing scaling provides the best quality scaling for 1080, 720, and SD, sources for 4k projectors and TVs. Unlike other scaling technology Lumagen’s NoRing scaling does not add “halos” around edges caused by the ringing in other scaling algorithms.

Reference quality colourimetry is an often-overlooked part of a quality home theatre. Automated audio room equalisation has become commonplace. In a trained calibrator’s hands the processor can provide automated video equalisation using third party calibration software, with more accuracy than the non-3D LUT based calibration employed by television and projector manufacturers. With the comprehensive 4913-point 3D LUT based colour management system you see what the director intended.

Other important features include the best quality anamorphic screen support for HD and 4k UHD sources without the need for an expensive anamorphic lens. Precise geometry adjustment including size, masking, and vertical keystone correction are also available. The processor’s Non-Linear-Stretch (NLS) feature allows the user to modify HD 16:9 sources in a user customizable way to fill an anamorphic screen. For 16:9 screens and TVs, an anamorphic image can be placed anywhere in the active screen area. Multiple output configuration memories allow for features such as day and night optimisation, and multiple displays or projectors in a single system.

The adaptability of the Lumagen Radiance Pro is second to none. Using Field Programmable Gate Array (FPGA) technology, the scaler can add hardware image processing and setup features long after installation with a simple software update. Just as 3D video support was added to earlier models years after introduction, the RadiancePro will be adding new features over time. One example is High-Dynamic-Range (HDR). The processor will allow features like HDR, and Rec 2020 colour space, to be viewed on older displays and projectors, to the best of the display or projector’s ability. The processor can even split the video and audio so current 1080p audio processors can be used with 4k sources.
