28 Setting Up the Projector
For Stereo Mini-Jack Audio Output Ports
Some video devices, especially camcorders, may have a stereo
mini-jack audio output port. In this case, use a commercially-available
stereo mini jack audio cable to connect to the projector, as shown
below:
1. Connect one end of the audio cable to the Audio jack
corresponding to your video source. For example, if you’ve
connected your video device to the projector’s
S-Video port,
connect the adapter to the Audio jack next to it.
2. Connect the other end to your video device’s audio output port.
If you don’t need to make any other connections, you can plug in
your projector and turn it on. See page 30 for instructions.
note
Each input port has its own
dedicated audio output jack.
To play sound from a source,
you must connect the audio
cable to the correct audio
output jack.
When you switch the video
source, the projector
automatically plays sound
from the new source.
