Hi,
I would add audio cables to the mix as well.
If you're not too clued up on cables, I want to clarfiy the previous post:
- Only power goes to the projection screen
- All the rest will go to the projector's location (including 1 x power)
Projection screen-wise, if you are making a false wall, maybe you can add a bit of false ceiling for the projection screen too. This will allow you to get an in-ceiling screen.
This will get you a very clean looking cinema. You can go to
www.beamax.com to see some examples of these sort of installations.
www.homecinemagallery.com has some nice inspirational material as well.
Good luck with the works.
