When the computer is using the DisplayLink connector, both audio and 

video are sent over the USB cable to the projector and audio will play from 

the projector's speakers.

For inputs other than DisplayLink, to use the projector's speakers, connect 

the audio source to the Audio In Computer or Video connectors.

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 Manager User's Guide 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 the correct source is active.

•

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.
