Connecting an S-Video or a composite Video source device
Examine your Video source device to determine if it has an unused S-Video or Video output socket available:
•
•
If it has both sockets, use the S-Video output socket for connection as the S-Video terminal provides better
picture quality than the Video terminal. See
picture quality than the Video terminal. See
for details.
•
If it has either of the output socket, you can also continue with this procedure.
•
If not, you will need to reassess which method you can use to connect to the device.
If you have already made a Component Video connection between the projector and the video source
device, you need not connect to this device again using an S-Video or composite Video connection as this
makes an unnecessary second connection of poorer picture quality. You need only connect using a
composite Video connection if both Component Video and S-Video are not supplied on the video source
device (for example, with some analog video cameras).

To connect the projector to an S-Video/Video source device:
1.
Take an S-Video/Video cable and connect one end to the S-Video/Video output socket of the Video source
device.
device.
2.
Connect the other end of the S-Video/Video cable to the S-VIDEO/VIDEO socket on the projector.
3.
If you wish to make use of the projector (mixed mono) speakers 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 socket of the projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See
