Connecting a composite video source device
Examine your video source device to determine if it has a set of unused composite
video output sockets available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the
device.
To connect the projector to a composite video source device:
1. Take a video cable and connect one end to the composite video output socket
of the video source device.
2. Connect the other end of the video cable to the VIDEO socket on the
projector.
3. If you wish to make use of the projector (mixed mono) speaker in your
presentations, take a suitable audio cable and connect one end of the cable to
the audio output socket of the device, and the other end to the AUDIO IN
socket of the projector.
4. If you wish, you can use another suitable audio cable and connect one end of
the cable to the AUDIO OUT jack of the projector, and the other end to your
external speakers (not supplied).
Once connected, the audio can be controlled by the projector On-Screen
Display (OSD) menus. See "Adjusting the sound" on page 35 for details.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 16 for details.
• If the selected video image is not displayed after the projector is turned on and the correct
video source has been selected, check that the video source device is turned on and
operating correctly. Also check that the signal cables have been connected correctly.
• You need only connect to this device using a composite video connection if Component
video and S-Video inputs are unavailable for use. See "Connecting video source devices"
on page 16 for details.
