    HI,

    am undertaking an outdoor showing in Speyember on a 10 metre wide screen...

    Want to stack two or more projectors to get brighter picture...

    So question is:

    Can I get a composite or s-video signal splitter to send the signal from one player to two or more projectors?

    Any help gratefully recieved....


    Regards,

    Martin.

    PS Before anyone asks,....yes this is a properly licenced public showing.!

    The answer is yes - though there are several ways of doing it.

    Probably the best option is a Video Distribution Amplifier. One signal Input sent to 5 or more Outputs each of equivalent quality. You can get VDAs in various forms including Composite, S-Video or Component. They are available to hire as well.

    The other ways is a DVD player with dual composite outputs, or projectors with a Loop Through feature. This is where the projector has an output to feed a signal to a second display.

    A note on the projectors - I'm sure you know you will need projectors capable of stacking. This is where one projector sits on top of the other so allowing the images to overlap. The images are are aligned using Lens Shift and then fine adjustment on the stacking bracket. You can't use keystone, the pixels won't line up properly.

    Good luck

    Go on RGB's website and have a look at the Extron stuff, there's loads of ways to do this.

    The hardest part is choosing the right projector or distortion box to allow you to double stack. I do this all the time with pre-polarised projectors to achieve stereo viewing, make sure your layout is thought through carefully otherwise the display will be a bugger to get looking right. If the PJ has a manual zoom, use the mid zoom to get a bit of tolerance on throw and minimise possible lens errors, barrelling can be an issue on 'cheap' PJ's.

    Should look good though, good luck.
