Designed to eliminate the extra step of finishing the screen with trim, the 220V 21804EBLSI Tensioned Advantage Electrol 50 x 80" Ceiling-Recessed Motorized Screen from Da-Lite is designed with ceiling trim already in place. Once the screen is installed, the screen's trim conceals the rough opening eliminating the need to complete additional trim work. Sliding installation brackets are included to make it easy to attach the screen housing to the structure above the drop ceiling.

The Advantage Electrol screen features simple in-ceiling installation that can be done in two stages. The screen case can be installed during the rough-in construction stage and the fabric assembly can be completed during the finishing stage.

Note: This box is part of a system. To complete the system you will also require the fabric, roller, and motor assembly. Purchasing the box first allows the box to be installed during the "rough-in" phase of construction. The screen and other components can then be installed once construction is complete. Please be sure to select the fabric, roller, and motor assembly with the exact size and features as designated by this box. The fabric, roller, and motor that goes with this model number is: 21804EFLSI.

Q: 6. Will this adapter work directly with 77mm Rokinon Cine lenses? The outside diameter at the front of my cine lenses appear to be approximately 80-83mm, where the lens hood would mount. Does this adapter clamp onto the outside of the lens thread where a lens hood would sit?

A: For my understanding, this particular Genustech Clamp On adapter 80 mm ring is a 'stand alone' clamp on adapter that will only work with a modified lens type or those Duclos Lens, in which I never had used one before. It will not work with any type of screw in adapters or screw on lens. I had ordered this adapter once before and hope that it would work on both my Canon lens and Samyang (Tokinon South east asia title?) with a screw on adapter lens for various size. But it doesn't work. So i had to order screw on adapter ring instead to be able to fit on my Genus Tech matt box.Hope this help.

A: No, the Bluetooth feature on the Track E is only for syncing and it does not carry an audio signal for headphones, just status. Perhaps they may add that type of option in the future. For now, the only way to listen to the audio for monitoring is through the wired headphone jack on the Track E.
