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 USB 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
spe
akers, connect the audio source to the Audio In Computer or Video
connectors.
To adjust the volume, press the Vol
ume 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
conn
ector, 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
conn
ector, Computer or Video.
• Make sure the volume is turned up enough. Press the Vo
lume 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, see page 36.
• Make sure that you are connected to an “audio out” connector on the
s
ource 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 is passed to the Audio Out connector.
