Using the audio

Using the projector’s speakers

When the computer is using the DisplayLink or HDMI connector, both 

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

from the projector's speakers.
For inputs other than DisplayLink and HDMI, 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 or HDMI 

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. By default, audio in VGA 1/2 corresponds to VGA 1, VGA 2 

and LitePort, audio in composite s-video corresponds to S-video and 

Composite. You can changes these assignments (on page 35).

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.

Connecting external speakers

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 are passed to the Audio Out 

connector.
