When the computer is using the DisplayLink or HDMI connectors, both audio and 
video are sent over the respective cable to the projector and audio will play from the 
projector's speakers.

For inputs other than DisplayLink and HDMI, connect the audio source to the 
associated audio connectors in order to use the projector's speakers.

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:

•

If your computer is using the projector's DisplayLink connector, see the 
InFocus DisplayLink Software User's Guide on the website at 
www.infocus.com/displaylink for audio troubleshooting information.

•

Make sure the audio cable is connected to the correct audio in connector, 
Computer or Video.

•

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. 

•

Make sure that you are connected to an audio out connector on the source as 
opposed to a line in or microphone connector.

•

Adjust the audio source.

•

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

The projector can be attached to external amplified speakers by connecting a 3.5mm 
stereo audio cable from the Audio Out connector on the projector to the amplified 
speakers. Alternatively, you can bypass the projector’s audio system and connect 
the audio directly from your source to a stereo or home theater system. 

NOTE: DisplayLink and HDMI audio is passed to the Audio Out connector.
