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, use the buttons on the keypad or remote.

To adjust the bass, treble, balance, or loudness, use the Audio menu (see page 33).

To mute the sound, press the Mute button.

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. Press the volume button on the keypad or remote.

Make sure you are connected to the corresponding audio in for your source. Computer 1 and 2 share a single audio input, as do Video 2 and 3.

Adjust the audio source.

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