Using the audio
Using the projector’s speakers
Connect the audio source to the Audio In connectors to hear audio through the 
projector speakers.  
Amplified speakers may also be connected to the projector using the Audio Out 
connector.
To adjust the volume, press the Volume buttons on the remote.
Troubleshooting Audio
If you aren’t hearing the audio, check the following:
Make sure the audio cable is connected to the Audio In connector on the 
projector, and that the other end of the cable is connected to an Audio Out 
connector on the source (not a “line-in” or “microphone” connector).
Make sure the volume is turned up enough. Press the Volume button on the 
remote.
Make sure the correct source is active.
Adjust the audio source.
If playing a video, make sure the playback has not been paused.
