30 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
audio adapter cable (3.5-mm stereo miniplug to two male RCA plugs)
to connect to the projector:
1. Connect the red and white plugs on the audio adapter cable to the
L-Audio-R jacks on the projector.
2. Connect the other end of the audio adapter cable 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 32 for instructions.
