Using the audio

Using the projector’s speakers

Connect the audio source to either the Audio 1 or Audio 2 connectors to hear audio through the projector speakers.

To assign the audio to a particular source, go to the Setup menu and choose the Audio Inputs feature. Defaults are as follows: Audio 1 is set to VGA 1 and VGA 2 with microphone, and Audio 2 is set to Composite with audio. See page 33 for details.

Amplified speakers may also be connected to the projector using the audio-out connector.

To adjust the volume, press the Volume buttons on the keypad or remote.

Troubleshooting Audio

If you aren’t hearing the audio, check the following:

•Make sure the audio cable is connected to the Audio 1 or 2 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 keypad or remote.

•Make sure the correct source is active.

•Adjust the audio source.

•If playing a video, make sure the playback has not been paused.
