Let us know your thoughts on any improvement @wooferocau Hi Mark, Initial impressions are very positive! Audio......a definite improvement in dynamics . Video..... the already "clean" image from the Lumagen is improved a step further......cleaner image with improvements to fine detail. There will be many sceptics that will dismiss the idea of a Linear PSU bringing any improvements , but i DO NOT care .........i am very very happy with the outlay/results on the Linear PSU... For interest sake...... Jim Peterson himself acknowledged the "Possible" benefits of an "Analogue" ( Linear) PSU when used with the Radiance Pro... 2 Link to comment Share on other sites More sharing options...
TP1 Posted October 28, 2020 Share Posted October 28, 2020 Although the video source and processing is all digital, the actual electrical signal that travels to the projector and audio processor is still analog. That is to say that digital signals transmitted electrically are a series of analog electrical voltage pulses. A cleaner electrical signal will ordinarily result in less potential for errors and jitter that would otherwise be caused from electrical noise being transmitted from the SMPS. Lumagen is very good at cleaning up the video signal anyway but the improvements from a decent LPSU are there . Link to comment Share on other sites More sharing options...
hifiman Posted October 30, 2020 Share Posted October 30, 2020 Anyone here have any electronic masking solutions setup with their lumagen? I'm due to get a lumagen (deposit paid) and my CIH scoped screen has electronic masking with a remote & sensor. So far I've been told it should work with Control4 system or perhaps via a scripted program using a raspberry Pi4 using IR control. I'm more interested in the latter but happy to know of other possible solutions. Or maybe just have the screen setup as always 2.35:1 and get the lumagen to scale 16:9/Imax material to scoped. Anyone doing this, if so how does it look? Note: I have a ISCO IIIL anamorphic lens in this setup. Link to comment Share on other sites More sharing options...

While it does work and some love it, I still prefer the standard 16x9 with black bars at the sides. Also with a number of TV shows streaming in 1.85:1 and sometimes larger, I get good results by automating different zoom positions to maximise the picture size on the screen.

Yup since i already have the electric horizontal masking working I think I'm already halfway there, just need to work out a way to automate it for scoped vs 16:9 content.

It's an LP Morgan Novares fixed frame screen that came with their own custom side masking solution (LP Morgan Galleria Eclipse). Works pretty well. I think it's a unity gain screen but I'll be swapping the material with a studiotek G4 material soon. Link to comment Share on other sites More sharing options...

Administrator Marc Posted November 17, 2020 Administrator Share Posted November 17, 2020 I assume you used auto-translate subtitles? The translation is not great. Such a shame it's not in ENG. Link to comment Share on other sites More sharing options...
xPLAYRZx Posted November 17, 2020 Share Posted November 17, 2020 Correct. The auto translate on this one isn't the best, you're right. What I liked about this video is it's refreshing to actually see footage of the Lumagen at work, with on/off comparisons, something I feel is missing from Lumagen own marketing material.

wooferocau Posted December 10, 2020 Share Posted December 10, 2020 Currently in Beta , BUT official release VERY shortly.... https://www.avsforum.com/threads/new-lumagen-radiance-pro-series.2172017/post-60318325 jrp Registered Joined Jan 7, 2003 1,670 Posts #9,778 • 7 h ago Concerning the next update with even more improvement for the already spectacular DTM: We are close to the next big release. This release improves the "back and forth" scenes cuts which were difficult. Pat said the second time the same scene shows in a number of the cases actually does have different levels. The DTM was over emphasizing the difference, but Pat has found ways to adjust the DTM algorithm to keep the back and forth scenes as close as possible. There were also a few scenes that had other issues. One type of scene I know about had enough areas with bright objects to fool our zone-based analysis. Pat redesigned the zone analysis, which improved these scenes. I just discussed timeframe for the next release with Patrick. He said he is working on a couple additional scenes and thinks we can post the next release this weekend. ====== Usage comment for the upcoming release: As we have seen in the past changing the algorithms can also change the recommended defaults. Let me first say that the current recommendations (Max Light = 4 to 6 times measured light in nits, Dyn Pad = 2, Low-ratio = 31) still work well. That said, I am planning to change my settings slightly based on viewing the results of DTM for this upcoming release. Max Light: I have been at 5x (400 for a measured max of 78 nits) for our Lumagen Demo Theater RS4500. With the new release I prefer setting Max Light 6x measured max. This helped with some bright details (e.g. Mad Max: Fury Road sand storm scene explosions). Dyn Pad: We changed to a recommendation of 2 (from 5 to 6) a while back. This was due to changes in the algorithm allowing the scene headroom to be reduced. The effect of Dyn Pad changes slightly in the upcoming release. In my viewing, IMO the Dyn Pad of 2 seems to reduce the headroom slightly from the previous release. Patrick said there were not intentional changes to the Dyn Pad headroom, but he said he did change the MaxCLL effect on calculations He said this could affect Dyn Pad. Dyn Pad of 2 still looks great for most scenes but one scene I found where I wanted a higher Dyn Pad was "The Meg" in the "Hatch scene" with the red haze in the hatch (this is in teh first couple minutes of the movie). For this scene I ended up preferring Dyn Pad = 5. I also found I preferred Dyn Pad = 5 for Mad Max, and for several other title. The difference in scene brightness between 2 nd 5 seems less to me, and I saw more bright detail changing Dyn Pad to 5. I should note that I already have discussed this with Pro owners using the current release and suggested Dyn Pad = 5 in some cases. So this is not entirely new. Dyn Pad remains a trade-off between higher scene brightness (=2) and more detail in very bright objects (=5). This has not changed, but my preference has. I am currently thinking I will set Dyn Pad = 5 for the upcoming release. So, my recommendation is try 2, 3, 4, and 5 for Dyn Pad over a lot of material and then select your preference. I am not changing Low Ratio or DeSat settings for this new release. I hope this is helpful to everyone and that I have not opened a can of worms as my posts sometimes do. Jim Peterson Lumagen, Inc.

wooferocau Posted January 25, 2021 Share Posted January 25, 2021 jrp Registered Joined Jan 7, 2003 1,717 Posts #10,645 • Lumagen, Inc. is excited to announce the latest addition to the Radiance Pro family of 4k video processors, the Radiance Pro 5348. The Radiance Pro 5348 takes the ultimate video processor to the next level by minimizing output-jitter and electrical noise. The Radiance Pro 5348 has ten 18 GHz inputs, two 18 GHz outputs, and one audio-only output, in a 1U case. This is a fixed configuration. Rather than go into details here, I have written a white-paper on the new Radiance Pro 5348 and it is attached to this post. I am sure there will be questions, but I tried to over the most likely ones in the FAQ in this introduction paper. Please feel free to post questions, or email them to support at Lumagen (.com).

cwt Posted January 26, 2021 Share Posted January 26, 2021 A unique solution for the poor integration of video clocks controlling audio with tmds in the regular hdmi "standard" not to mention the different interpretations of ce's as to what their hdmi ports interact with properly. Much better having a high precision clock timing things locally . Hopefully the full gamut of 2.1 features like VRR/QFT for gaming will get a firmware upgrade ; the higher resolutions like 4k 120hz can wait.. Very clever differentiating this model from the competition ; some of the jitter figures on ASR dont inspire confidence in design Link to comment Share on other sites More sharing options...
TP1 Posted January 28, 2021 Share Posted January 28, 2021 It seems there is still development happening with this unit particularly in relation to LAN interface. Ultimately it would be great to see netwok based control via an APP. I'd also be interested to see how the picture differs with the current model that uses a Linear power supply.

wooferocau Posted February 3, 2021 Share Posted February 3, 2021 Just some initial feedback on the New 5348... So far i am very very much liking what i see......YES what i see...... The current 4*** series ( mine being a 4242) has provided the "Cleanest" most "Natural" looking image that i have ever had in my theatre.........and i have owned and used VP,s such as madVR HTPC , madVR Envy Extreme ........and Envy PRO. The NEW 5348 for me just set the bar again !! I am noticing and improvement even over the superb 4**** series in slightly less image noise AND increased detail ...particularly "Fine" "intricate" detail !! I assure you it is real and NOT just "wishful thinking" or "Hype". I haven't as yet assessed the AUDIO side of the 5348 as i have been to engrossed in the video analysis . Audio is next on the list... At this moment in time IMO....... "IF" you want the a absolute pinnacle in image performance via a video processor ......the 5348 is it..... More to come...... 7 Link to comment Share on other sites More sharing options...
