See What the Director Intended ™

The Radiance Pro™ series supports 4k60 inputs, and outputs, including HDCP 2.3, HDR10, and HLG, and is compatible with Dolby® LLDV™ sources. 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 22-year legacy of video processor development by continuing to enhance features and algorithms, and adding a single-input, single-output model for those who would like to place the Radiance Pro after the AV switching.

The Radiance Pro series of video processors offers up to ten inputs, four outputs, and a multitude of video 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 cinema.

Optimizing HDR content has perhaps become the most important video processing feature. The Radiance Pro Dynamic Tone Mapping (DTM) analyzes multiple regions of every frame of content, detects scene changes, and optimizes the image 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 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 4k projectors and televisions. It should be intuitively obvious that home cinema scaling must be evaluated at viewing distance using actual moving image video content. The Tektronix PQA600C quantitative image analysis program is used by major studios and broadcast networks and includes 30 years of development by perception physicists. It includes viewing distance in its evaluation of scaling. The Radiance Pro has the industry’s best motion picture scaling and scores more than 20% higher than the competition using the Tektronix analysis software. Lumagen’s 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 an 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 Radiance Pro 5XXX series 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. Reduced jitter at the DAC reduces distortion. Lumagen has many reports of the 5XXX significantly improving audio due to this ultra-low jitter HDMI output.

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 DTM, and Color Management System, you can See what the director intended™.

Other features include image-based instant-auto-aspect detection and selection for HD, 3D, and 4k UHD and HDR sources. Anamorphic support 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 zoom, and/or cropping, can fill a larger portion of the screen. Multiple configuration memories allow for different independent configurations, such as day, night, sports, and black-and-white.

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 Dynamic Tone Mapping was added four years after product introduction and is available to all Radiance Pro owners by simply updating to the latest free release.

"Reference status picture processing with a wealth of controls and futureproofing potential. Worth the outlay for high-end systems, but installation isn't for the AV novice.:

A Magical Start to an Epic Series
Format: Paperback
I read Amulet: The Stonekeeper with my class, and the students couldn’t get enough of it! The artwork is absolutely stunning, and the story grabbed their attention right away. Even reluctant readers were eager to see what happened next. The mix of fantasy, adventure, and relatable characters makes it the perfect series to hook middle-grade readers. As soon as we finished, they were already asking for the next book in the series!

I thought of it as a fantastical family adventure. Great artwork Wonderful Story
Format: Kindle
First thought You killed someone in the first few pages of a kids book! Wait Disney movies kill people off too. Okay, shock over. I likes how the mother helped keep the kids upbeat when the moved into the old home and had to clean it and on the way there she was understanding of their feelings and was encouraging them to like their new home. Even encouraging Emily to learn more about her great grandfather. Just not be like him. Emily was super brave for a kid who watched her father die and her mother get snatched by a monster. She took responsibility of her brother and the amulet and decided to help save her mother and the world that they were in. I liked the Emily has choices not just that she has to do something because she was given the amulet but she had the choice to. She also had the choice to seriously hurt someone but she made the choice to let him live even though he wasn't the nicest of beings. I like that she lets her younger brother help out and notices when he might be better suited for the situation because of his past favorite past time ( like my son, most kids and some adults...its gaming) The story was great. A little dark but you get the whole light at the end of the tunnel feeling. That the characters will achieve what the set out to do. I also enjoyed the whole family thing. The illustrations were wonderful. I even slowed down and went back to look at the artwork. I look forward to reading this series and being able to talk about it with my son. It was a great start to a fantastical adventure. Now that I think about it I'd recommend this to kids around middle grade but like I said my son has been reading the series for awhile so, maybe use caution it does have monsters and evil doers and its a little dark but not so much that I wouldn't say you shouldn't read this with a younger kid. I'm actually thinking about starting it with my youngest soon. Great characters, Wonderful story and artwork, a quick read ( at least for me, an adult), fantastical adventure. I'll continue to recommend it to others and look forward to reading it with my youngest and continuing the series.

A perfect start
Format: Kindle
This is exactly the kind of graphic novel I was looking for. Full of sweetness with a little bit of bite. Reminds me of the great comic series bone. Great story, great art, I can’t wait to get into the next chapter.

Draws You in to the Series
Format: Paperback
The Stonekeeper is the first volume in Kazu Kibuishi's graphic novel series. Although aimed at middle school, it is good for upper elementary school children, and is enjoyable for adults as well. 2 years after the death of Emily and Navin's father in a tragic car crash, Karen moves her children to the family's old house in a dense forest. Built by Karen's grandfather Silas who then disappeared, it has been abandoned for years. During the first night, they hear a strange noise, and Karen is captured by an Arachnopod, a creature from a parallel world, Alledia. Emily and Navin follow their mother into the parallel world where they find their ailing great-grandfather Silas. He tells Emily about the power of the amulet she found in his house. It is the key to ruling Alledia. Silas expires, but not before instructing his robot and animal minions to aid Emily and Navin. This first volume, besides setting the story arc, narrates the rescue of Karen. Unfortunately, she is poisoned setting up the next volume for finding the antidote. Besides an engaging story with compelling characters, Kibuishi is a fantastic illustrator. As with many exemplar graphic novels the spare text is amplified and much of the story told through his illustrations. The creatures of Alledia are strange enough to pique our imagination, but not so much that they are totally alien in form. After reading Stonekeeper, I am eager to see what happens next with Emily and Navin, and their company.

wow
Format: Paperback
I remember when I read in reviews that kids had gotten sucked into this story and had become fans of this series so quickly.... Well, my daughter resisted till page 13 or 14... but since then she's in it... She's very picky when it is about books and even that she's 9, she started to read in English only a few months ago ( we lived abroad,she reads other language) so she still prefers books that is easy to read. Anyway, get ready, this series is addicted... gooooood :) that is what we need :) I mean, you can complain that this is a comic book but still, at least the child has the book in his/her hand and not a tablet... and at least he/she reads... I'm really happy that I got this book for her.
