Setting Up the Projector 23
Playing Sound Through the Projector
You can connect a commercially available audio adapter cable to take
advantage of the projector’s built-in speaker. You can obtain an audio
adapter cable (3.5-mm stereo miniplug to two male RCA plugs) from
a computer or electronics dealer.
1. Connect the RCA plugs on the audio adapter cable to the
L-Audio-R jacks on the projector.
2. Connect the other end of the audio cable to your laptop’s
headphone jack or audio-out jack, or your desktop’s
speaker or audio-out 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.
