Using the audio
To play sound from the projector, connect your source to the Audio In con-
nector on the projector.
To adjust the volume, mute, or loudness, use the Audio menu (see page29).

Troubleshooting audio

If there is no sound, check the following:
• Make sure the audio cable is connected.
• Make sure mute isn’t active.
• Make sure the volume is turned up enough.
• Make sure you are connected to the corresponding audio in for your
source. Audio 1 corresponds to Computer 1, Audio 2 corresponds to
Computer 2, Audio 3 corresponds to Video 2 and 3, and Audio 4 cor-
responds to Video 1.
• 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 speakers that have their own
power source by plugging a speaker cable into the projector’s Audio Out
connector.
