26 Setting Up the Projector
Playing Sound Through the Projector
You can play sound through the projector’s speaker system.
1. Locate the appropriate cable and connect it to the Audio jacks on
the projector.
2. Connect the other end of the cable to the audio output
connector(s) on your computer or video equipment.
Turning the Projector On and Off
Turn on any connected computer or video equipment before starting
the projector so it can automatically detect and display the image
source. If you turn on the projector first, or have multiple pieces of
connected equipment, you may have to select the image source
manually (see page 32).
