Using the audio
Using the projector’s speakers
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. By default,
Audio 1
corresponds to
VGA 1
,
Audio 2
corresponds
to
VGA 2
,
Audio 3
corresponds to
Component
,
Audio 4
corresponds to
S-
video
and
Composite
, and
Audio 5
corresponds to
RGBHV/YPbPr
. You
can change these assignments, see page 32
.
•
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.
