This document summarizes different types of technical stage projectors: - Long throw projectors project from a distance and enlarge the image, while short throw projectors use mirrors to project from closer. - QLab is software that can control multiple projectors showing different images simultaneously. - A matrox is a device that controls 3 projectors/screens at once, allowing different images on each for effects like split screens.

Can be HD
Can be connected to a PC, DVD, Camera
Has ports for VGA cables, USB, Kettle
Lead, Phono Cables
The further away it is the bigger it gets
The image can be inverted to accommodate its
use for the back of the stage

The projector uses a mirror to project.
The image can be inverted to accommodate its use
for the back of the stage
This type of projector is usually used at a shorter
distance.
For example if there was no space to rig a long throw
projector in front of a screen but there was a short
space behind the screen a short throw would be used

5. Matrox



A matrox is the device which controls three
different projectors or screens at once.
Each projector can show a different image
A matrox would be useful when a split screen
is trying to be shown on stage; for example on
the left of the stage it could show the inside of
a church but on the right it could show a grave
yard and then the third projector could show
the sky.
