Using the audio
Using the projector’s speaker
To use the projector’s speaker, connect your source to the Audio In connec-
tors (L and/or R) on the projector’s composite connectors.
To adjust the volume, press the Vol u me buttons on the keypad.
Troubleshooting Audio
If you aren’t hearing the audio, check the following:
• Make sure the audio cable is connected.
• Make sure the volume is turned up enough. Press the Volum e button
on the keypad or remote.
• Make sure the correct source is active.
• Make sure that you are connected to an “audio out” connector on the
source as opposed to a “line-in” or “microphone” connector.
• Adjust the audio source.
• If playing a video, make sure the playback has not been paused.
Connecting external speakers
The projector can be attached to external amplified speakers by connecting a
3.5mm stereo audio cable from the Audio Out connector on the projector to
the amplified speakers. Alternatively, you can bypass the projector’s audio
system and connect the audio directly from your source to a stereo or home
theater system.
