Lumagen Radiance Pro 4140 Update

September 3, 2024

Press Release

Some important additional info on the Radiance processor(s):

1. The new 4140 as well as all Lumagen Radiance Pro processors can now directly control the Seymour-Screen Excellence motorized masking systems.

From Lumagen president Jim Petersen: We are working with Seymour to allow customers without a control system to have the Radiance Pro directly control the masking system. One way to think about this is putting the extra cost for the Seymour masking screen into the budget, while avoid the large cost of a Crestron, or other, control system where the cost of the programming far exceeds the controller hardware cost.

The Lumagen Radiance Pro auto-aspect sends the detected aspect ratio to the Seymour screen mask controller as an aspect selection when a new source aspect is detected. The installer programs the Seymour mask controller so that the various aspect selections position the mask at the proper location.

The Radiance Pro sends commands to the Seymour screen masking for 4:3, 16:9, 1.85, 1.90, 2.00, 2.10, 2.20, 2.35, 2.40, 2.55, and 2.76. Each of these positions is programmed into the masking controller so that when the Radiance Pro sends the command selecting an aspect ratio the mask will be positioned in the correct location.

2. Additionally, between now and end of September, Lumagen is upgrading the output on the 4140 from 9G to 18G. 

Here is some tech on that from Jim on what 18G out gets the purchaser/user:
A 9-GHz output handles 12-bit 4:2:2 at 4k24, but is limited to 8-bit 4:2:0 for 4k60. The Radiance Pro output dither mitigates this difference, but for those that want no compromises, the 18 GHz output allows 12-bit 4:2:2. - Jim Peterson
