    Im in the process of buying a 808S here on the forum :thumbsup: i currently use a little LCD mounted on the ceiling. I want to do the same with the Barco and need to know how much clearance between the ceiling and the 808 I will need. My screen starts about 10cm down from the ceiling. Also will I need the proper Barco ceiling mount bracket or can I build my own fixings? If its just a question of the correct size bolts then Im sure I can make something myself. Also In all honesty how hard are CRTs to install? Do you definately need a professional installer or with some home work and good DIY skills can it be accomplished myself? As Im experienced with all sorts of AV gear but a relative newbie to CRT any advice would be very welcome :confused: :hiya:

    Hi Thunder,

    Can't advise on the specific Barco Qs, but I'm sure you'll be able to manage without a professional install. :smashin: Not knocking the pros at all, but if you have basic DIY skills and some electronics knowledge (mainly for the terminology) you'll do OK. Oh - and you need tons of TIME and PATIENCE! If you don't - then go for a pro install.

    You'll be learning as you go, and you'll need to see it as something of a "hobby". If you just want it up there and working ASAP you WILL be frustrated. You'll need to be referring to this forum (and others) a lot.

    I have the characteristics mentioned above, and after a month or so had a first-time PJ on the ceiling that I'm VERY happy with. It's a NEC 6PG, which is by all accounts a difficult PJ for a noob to set-up compared to a Barco. You'll probably be much quicker with a Barco.

    So go for it! :thumbsup: If I can do it I'm sure you can. You've already taken the first step in the right direction by seeking help on here.

    Good luck!

    Have you ued the Barco Lens Windows program to calculate the distance and drop etc...that should tell you the drop required.

    You can download it either from the Barco site or from www.crtprojectors.co.uk.

    Cheers, Lee

    Have used it for calculation of projector distance but didnt quite understand what figures I needed to enter to calculate drop? :confused: Also it has a option for angle? As far as I knew the projector has to be placed as horizontal as poss?

    Well from what I understand the drop of the PJ is indicated by the value of A which is often negative.

    So for an 80"x45" 16:9 ratio screen you should get the following results:

    [​IMG]

    The program assumes that the top of the screen is level with the ceiling so this gives you a PJ drop of -8.1".

    So if you wanted a 12" drop at the top of the screen you would need a 3.9" gap between the ceiling and the PJ.

    I should pint out that this is all just theory as I went for a DLP PJ in the end but spend many hours trying to mentally fit a Cine 7LT into my room.

    Hope that helps.

    Cheers, Lee
