S-Video Connection
Some video devices can generate S-VHS video, or
S-Video (Y/C). The MP8650 will accept this signal
through the S-VIDEO1 or S-VIDEO2 connectors.
The S-VHS cable has identical round four-pin
connectors on either end (Figure 3-6). Connect one
end to the S-Video jack on the input source device,
and the other end to the S-VIDEO1 or S-VIDEO2
terminal on the MP8650. Remember to connect the
audio cables for sound output.Four-Pin Connector S-VHS Cable
Figure 3-6. S-Video Input
Video/Audio Connection
Find the small, circular connector on your camcorder, laserdisc player, VCR, or other video source marked
VIDEO OUT, TO MONITOR, or something similar.
Use the 3-conductor video/audio cable and insert the video (white) connector into the video output jack of
your video source device.  Connect the other end into the MP8650 VIDEO1 or VIDEO2 connector.
Next, find the AUDIO OUT terminals on your VCR or other audio source. Insert the left and right audio cable
connectors (Figure 3-7) to the input source. Connect the other end to the AUDIO-L and AUDIO-R terminals
on the MP8650.
Figure 3-7. 3-Conductor Video/Audio Input Cable Note
The MP8650 projector is a stereo device. However,
the projectors built-in speaker is monophonic.
Stereo sound played through the speaker becomes
monophonic due to an internal sound mixer that
converts stereo to mono.
If you are giving a multimedia presentation with stereo sound, you may want to consider connecting the
MP8650 audio-out L/R jacks to a  high-quality stereo system.

3-2. Projector Set Up
The meeting room is your operating environment and any stray light hitting the projection screen will become
glare. It is best to use a meeting room without wide-open windows. If there are ªlight stripesº from venetian
blinds, try to find a viewing area thats away from them ± and remember, the light stripes will move as the
hour changes.
Ambient Light
Whenever you have a choice, light the room from the rear, away from the projection screen. The MP8650 has
a brightness adjustment to achieve the best image possible.
Distance to Viewing Screen
The MP8650 can be used in a small or large meeting room to project a quality image from 51 cm (20 inches)
to 762 cm (300 inches) in size. The distance between the projector and the viewing screen and the zoom lense
setting (minimum to maximum) will determine the size of the projected image. Refer to the table in Section
9-3 to determine how far away from the viewing screen you need to place the projector to fill the screen with
the projected image.
Remember that increasing the projector-to-screen distance also decreases the images brightness dramatically.
In other words, as the image grows larger, it also grows dimmer.
For best results, experiment to find the right combination of projector-to-screen distance and room lighting.
Carrying Handle
The MP8650 has a carrying handle that folds into the top of the projector housing.  To raise the handle, push
up on the back end of the handle (Figure 3-10) and then lift upward.
Figure 3-10. Unfolding Handle
Ceiling Mount Considerations
An optional ceiling mount bracket (Figure 3-11) is
required to install the MP8650 from the ceiling.  For
this type of installation, the image must be inverted.
Refer to section 4-6 Inverting the Image for more
details.
See section 10-1 to order the ceiling mount kit.

Adjusting the Projector Elevation
The elevation can be adjusted by turning the foot adjuster (Figure 3-12) to raise or lower the angle of the
projector.
Figure 3-12. Foot Adjuster
 Note
Both adjusting feet must be raised or lowered the
same amount to project a level image on the
viewing screen.  The elevation can be adjusted up
to seven degrees.
Rear Projection
A semi-transparent screen (Figure 3-13) can be used to project an image and view it from the backside of the
viewing screen.  For this type of installation, the image must be inverted.  Refer to section 4-6 Inverting the
Image for more details.
