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.
Connecting external speakers
The projector can be attached to external speakers that have their own
power source by plugging speaker cables into the projector’s left and right
Audio Out connectors.
