The room.

Fortunately  I was able to splitt of a part of our living room for the beoliving installation. The new room is 4m x 3,60m and seperated form the sitting area by two sliding doors. I took the opportunity to discuss my project with a acustic engineer and he provided a detailed plan how to build the sliding door and the two small walls with acustic treatment.

The acustic expert provided a plan for all walls including the ceiling to gurantee the perfect sound....however, I decided to do this step by step so I painted the front wall in dark grey to rise the contrast and avoid a "light" frame around the screen provided by the JVC HD1. This is a drawback of the D-ILA technology, so you need to paint the wall in a dark color. But at the end of the day it looks pretty nice! Hopefully by the end of this year I will have the full acustic treatment, allmost all parts are alreday purchased....

Great project Karsten, and thanks for the pictures.
I think your cinema is screaming out for a Beo5, do you have one?

Please show us more pictures of your project...😁

Regards Rasmus

Very interesting project and its good to know your using the JVC projector instaed of the outdated samsung offerings.

Should be  a great setup at a fraction of the cost.

Andy T.

Thanks Andy!

No, I don't have a Beo5. After I saw and touched the prototype in Struer I orderd one, however, with all the problems in the beginning with the software I am quite happy that I still have my Beo4 Cinema!

But one reason for the Beo5 could be it's native support for Busch&Jäger IR light control (at least an training doc from B&O stated that)

The Screen

Selecting the right screen was a little bit harder than I had thought in the beginning. As an B&O fan I asked for the best solution first, and the experts tell you Stewart Filmscreens are the best. So first, I checked out the different surfaces they offer, quite a difficult task....so Studiotek, or Firehawk or Greyhawk??? However, this question was answered very quickly when I got the first quote.....for a multi masking motorized system it was north of 10k Euro...so sorry, not in my budget!

I checked out different vendors, but in summary, I really have to say, the Stewart is by far the best. Anyway, I ended up with a Davision 4D Multiformat 2,44m. The cool thing with this one is the possibility to change the format from any 4:3 to 21:9 or whatever and store them 4 different memory places.

Unfortunately build quality and the way it is operated is not to great. After the first installation of the screen I realized that the viewing distance of 3,60m is to short for a 2,44m screen! Hmmm.... @#%&.

A friend of mine now is pleased with the 2,44m screen and I bought a new 2,24m one (lucky me, only 100 Euro extra in total).

And the worst thing of this screen is that the fine tuning of the format can only be done with a RF control and not with IR....and you have to enter a programming mode to do so. Not sure what the developer had smoked during the design process. Because every movie is different and for the prefect viewing expirience the masking bars need some fine tuning. OK, for the fifth of the stwart....

So the challenge is how to control this thing? With the multiformat option there is no trigger for on/off, the screen needs to know the right size to get down. The basic idea of the BS3 with the cinema trigger and a relay for up/down of the screen does not work.

In this case the Lintronic box can do the job, Micheal from Lintronic was so kind to implement the IR codes for 3 formats and the off-signal to the Lintronic box. So I can can control for example the 16:9 format and the off-signal with the Beo4. Cool, that works! Also switching to other formats is possible (e.g. from 16:9 to 21:9).

With the digital input of the Lintronic box it is now possible to lower the screen to 16:9 after hitting the cinema button (FORMAT 0) on the Beo4. I wired the cinema trigger output of the BS3 with the trigger input of the Lintronic box. Within the customer service menu it is quite easy to adjust the timings when the screen comes down, the projector should switched on and the image is switched from the plasma to the projector after FORMAT 0.

For all who try to do the same, the B&O docs are crab, Pin 5 is GND, Pin 6 is Cinema 1 and Pin 7 Cinema 2....it took a a couple of hours to figure this out.

 At the end, the ugly sreen case will be hided and two downlights on the left and right will underline a nice cinema expirience.

Nice job so far Karsten!  Likely to put some installers out of business!  

 As for lighting, have you looked at Lutron?  Their Grafik Eye 3100 series is available with a secret 'GBO' prefix part number that you might find useful. 

Interesting post here! I really look forward to the time that I can plan and afford my own project, this is right up my street.

Karsten, thanks for sharing all this info and I wish you good luck with the rest of your creation. Some photos as you get along would be great.
