This document provides information about different types of projectors and how to use the Qlab software on Macs. It describes long throw and short throw projectors, noting that long throw projectors can project to larger, more distant screens while short throw projectors are better for closer screens. It also explains that Qlab allows playing multiple videos and audio on Macs when used with a Matrox device, and provides basic steps for using Qlab including adding audio, connecting to a Matrox, and starting playback.

2. Long Throw Projector
• Can be HD and can connect
computers, DVD and live feed from
video camera.
• Has a VGA cable.
• Long throw can hit further away
screens.
• Has a focuser and built in speaker
• Used in front but can invert and
project from behind to avoid
performers blocking the picture.
• You would use a Long Throw if you
had a larger space and wanted the
projector to be discreet as unlike a
Short Throw it doesn’t have a flip
down lenses, therefore it is easier to
be hid and more aesthetically
pleasing. For example you would use
a Long Throw in a hall to do a
presentation to a large amount of
people.

3. Short Throw Projector
• Can be HD and can connect
computers, DVD and live feed
from video camera.
• Has a VGA cable.
• Short Throw would be used for
closer proximity screens.
• Has a focuser and built in speaker
• Used in front but can invert and
project from behind to avoid
performers blocking the picture.
• You would use a Short Throw if
space is short as it creates a better
picture from a closer projection.
For example you would use a
Short Throw in a performance if
the projector and screen was
within a close proximity.

4. Qlab and Matrox
MAC- QLAB
MATROX
Can have 1 image stretched
across 3 projectors.
Projectors don’t need to be used
one of the outputs could be to a
TV.

5. How to use Qlab..
• Only works on MAC’s.

Step by Step
• Press GO.
• Drop MP3 into Qlab (you can change name to sound queue).
• Click on preferences and connect Patch 1 to USB Audio
Codec.

loaded.
