Connecting External Speakers
You can output sound to external speakers with built-in amplifiers.
When you play sound through external speakers, the projector's
built-in speaker is disabled.
1. First connect your video and audio input cables as necessary.
2. Locate the appropriate cable to connect your external speakers.
Depending on your speakers, you may be able to use a
commercially available audio cable with a stereo mini-jack
connector on one end and pin jacks on the other end. For some
speakers, you may have to purchase a special cable or use an
adapter.
3. Connect the stereo mini-jack end of the audio cable to the
port on the projector.
Audio Out
4. Connect the other end of the cable to your speakers.
The projector's internal speaker is disabled while sound is output to
external speakers, but you can use the remote control to adjust the
volume.
