The Radiance Pro™ series improves on the award-winning Radiance video processor family by adding support for 4k60 inputs, and outputs, including HDCP 2.2, HDR10, and HLG. Winner of a Home Cinema Choice™ Best of 2021 award, and a Best Video Product award in Australia in 2021, the Radiance Pro is not standing still. Lumagen is adding to its 20-year legacy of video processor development by continuing to enhance features and algorithms.

The Radiance Pro family offers up to ten inputs, four outputs, and a multitude of processing, setup, and calibration features. Much more than an HDMI switcher, the Radiance Pro has a host of features to improve the image on your screen. It is considered by many experts to be an essential part of any quality home theater.

Optimizing HDR content has perhaps become the most important video processing feature. The Radiance Pro Dynamic Tone Mapping (DTM) analyzes every frame of content for multiple regions of each frame, detects scene changes, and optimizes the “transfer function” for each frame of content. Jon Thompson, a movie producer who is responsible for post-production image quality at a major studio, recently evaluated the Radiance Pro DTM versus the other DTM options. He said that “the other DTM options are not even in the same league as the Radiance Pro.”

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. Scaling is also essential for aspect-ratio control, especially when using an anamorphic lens. In addition, the Radiance Pro has a edge-sharpening feature that helps restore detail lost during compression of the digital content.

Minimizing signal jitter is an extremely important criteria for HDMI. The current 18 GHz 4XXX HDMI output card has a measured data jitter of about 80 pS. This is well below HDMI requirement of ≤102 pS for 18 GHz, and dramatically lower than competitive devices which have been measured at up to 450 pS of data jitter. The Radiance Pro 5348 further reduces data-jitter to about 45 pS. More importantly for audio, the HDMI output clock jitter has been measured at about 10 pS. This is an ideal clock to send to the audio processor to minimize jitter at the DACs. Lumagen has many reports of the 5348 significantly improving audio due to this ultra-low jitter HDMI clock.

Reference quality colorimetry is often overlooked as part of a high-end home theater. The Radiance Pro can provide automated video equalization, using third party calibration software, with more accuracy than calibration without a 3D LUT. Using the Radiance Pro’s Color Management System, you can See what the director intended™.

Other features include anamorphic screen support for HD, 3D, and 4k UHD and HDR sources, with or without an anamorphic lens. Image based auto-aspect selection, plus precise geometry adjustments including size, and masking, are available. The Radiance Pro’s Non-Linear-Stretch (NLS) feature allows the user to stretch 16:9 content to fill an anamorphic screen using their preferred settings. For 16:9 screens and TVs, an anamorphic image can be placed anywhere in the active screen area, or with some zoom, and/or cropping, can fill a larger portion of the screen. Multiple configuration memories allow for multiple independent configurations, such as day, night, sports, and black-and-white. For 4XXX models, dual-port I/O cards can be upgraded from 9 GHz to 18 GHz in the field. The Radiance Pro 5348 has a fixed I/O configuration.

The adaptability of the Radiance Pro is second to none. Using Field Programmable Gate Array (FPGA) technology, the Radiance Pro can add hardware image processing and setup features long after installation. The Radiance Pro is adding new features over time. One example is HDR video, which did not even exist at introduction. DTM was added four years after product introduction and is available to all Radiance Pro owners by simply updating to the latest release. Your Radiance Pro’s feature-set and performance are “only as old as its most recent software release.”
