							Connecting to a Video Source
53
You can connect the projector to an S-Video source, a composite video 
source, and a component video source at the same time. However, the 
projector automatically selects the S-Video as the video source. To 
display composite or component video, first disconnect the S-Video 
source.
The projector supports HDTV, NTSC, PAL, and SECAM video 
formats, and automatically detects and identifies the video format. 
However, you can specify that a single broadcast format be detected. 
(See Chapter 3.) Note that the projector will then be able to detect 
only one type of video signal.
The type of cable you use to connect the video source to the projector 
depends on whether you have composite video, S-Video, or 
component video. For composite video, use the audio/video (A/V) 
cable supplied with the projector. For S-Video, use the S-Video cable 
supplied with your video device or obtain one from your computer or 
video equipment dealer. For component video, use the BNC type 
cable that came with your video source. The illustration below shows 
the S-Video, component, and composite connectors.

To connect a video source to the projector:
1. Turn off the projector and video source if they are on.
2. If your video source uses a small, round, one-prong composite 
(RCA) video connector, you’ll need the audio/video cable that 
comes with the projector. If your video source uses a large, round, 
four-prong S-Video connector or a BNC type connector, you will 
need to purchase the appropriate cable or use the cable that came 
with your video source.
3. For composite video, connect the yellow RCA plug on one end of 
the audio/video cable to the projector’s Video jack. Connect the 
other yellow RCA plug to the video-out jack of your video source.

4. Connect the other plugs on the audio/video cable to the Audio 
jacks of the projector: insert the white plug into the L jack and the 
red plug into the R jack. Connect the plug at the other end of the 
audio/video cable to the audio output jacks of the video source. 
5. For S-Video, insert one end of an S-Video cable into the 
projector’s S-Video connector. Insert the other end into the 
S-video-out jack of your video source.
6. For component video, insert three ends of a BNC cable into the 
projector’s R/R-Y, G/Y and B/B-Y jacks. Insert the opposite ends 
of the cable into the Y/Video, C/R-Y, and B-Y jacks on your 
component video source. (Don’t insert any of the cable ends into 
the HD/Sync and VD jacks.)
7. Make sure the Computer 2/BNC switch is set to BNC.
Note: 
❐When the Computer 2/BNC switch is set to BNC, the projector is 
unable to project the Computer 2 image signal.
❐Use a standard BNC cable, which you can purchase from any 
computer store. The Computer 2/BNC video cable supplied by 
EPSON as an optional accessory does not work with component 
video.

Connecting to an External Speaker or 
PA System 
  
Although the projector’s internal speakers are enough for most small- 
or medium-size rooms, you can connect the projector to an external 
speaker or public address (PA) system for large rooms or to gain 
maximum benefit from the projector’s built-in 3D sound function.
To connect the projector to an external sound system, you need to 
obtain an RCA-to-3.5 mm stereo audio cable. You can get one from 
your computer dealer.
1. Turn off the projector and speaker or PA system if they are on.
2. Connect the cable’s 3.5 mm stereo miniplug to the projector’s 
Audio Out jack.

Note: EPSON offers the Mediaphile PAS (personal audio system) and 
the Mediaphile CVS (clean voice system) for external amplification. 
See page 5 for the part number and ordering information.
3. Connect the RCA plugs to the external amplified speaker or PA 
system. Insert the cable’s red plug into the Audio R jack, and the 
white plug into the Audio L jack.
Note: The internal speakers are disabled when an external audio 
system is used.
Turning the Equipment On and Off
It’s best to turn on the projector and its attached equipment in the 
following order:
1. Video source (such as a VCR), if your video source is not your 
computer
2. Audio source (if different from computer or video source)
3. Computer
4. External amplified speaker or PA system (if necessary)
5. Projector (follow the steps in the next section)
When you are ready to turn off the equipment, turn them off in the 
reverse order.

Turning the Projector On and Off
Follow these steps to turn on the projector:
1. Connect one end of the power cord to the projector’s power inlet. 
2. Connect the other end to a grounded electrical outlet. The power 
light on the projector’s control panel turns orange, indicating that 
the projector is in sleep mode. (The projector is not turned on 
yet.)
3. Remove the projector lens cap. 
4. Press the Power button on the remote control or control panel to 
turn on the projector. The power light flashes green as the 
projector warms up.
If computer or video equipment is attached, the computer or video 
signal is projected. Allow about 30 seconds for full illumination.

Warning: Never look into the lens when the lamp is on. This can damage 
your eyes. It is especially important that children not look into the lens.
When you want to stop projecting images, press the Power button 
again. The fan remains on and the projection lamp light flashes orange 
for about 60 seconds as the projector cools down.When the projector 
has cooled down, flashing stops. The power light remains orange. 
Note: If you press the Power button to turn the projector back on while 
the power light is orange, there may be a delay before a projected image 
appears.
When you are done using the projector, unplug the power cord.
Never unplug the power cord when the power light is green; this may 
damage the lamp.
