Playing Sound Through the Projector
Your computer probably has its own sound system; however, it may 
not be adequate for your presentation. If you need more volume, you 
can connect a computer audio cable to take advantage of the 
projector’s built-in speaker. You can obtain a computer audio cable 
(3.5-mm stereo miniplug cable) from a computer or electronics dealer.
1. Connect one end of the audio cable to the 
Audio1 jack on the 
projector.
2. Connect the other end of the audio cable to your notebook’s
 headphone jack or   audio-out jack, or your desktop’s 
speaker or audio-out port.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 30 for instructions.note
If you’ve connected two 
computers to the projector, 
you can play sound from 
both. Connect the audio 
cable for the computer 
connected to the 
Computer 2/Component 
Video 2
 connector to the 
Audio 2 jack on the 
projector. Connect the other 
end of the cable to the second 
computer. 
When you switch sources, 
the projector automatically 
plays sound from the new 
source.

Connecting to Video Sources
You can connect a DVD player, VCR, camcorder, laser disc player, 
digital camera, gaming console—such as Microsoft Xbox, Sony 
PlayStation 2, or Nintendo GameCube—or any other compatible 
video source to your projector. You can connect up to four video 
devices at one time. 
The projector supports HDTV, SDTV, NTSC, PAL, and SECAM, 
and automatically detects the video format. It can receive composite 
video, S-video, RGB video, and component video. The type of cable 
you need depends on the video source: 
■For composite video, use a commercially-available RCA A/V 
cable. See page 23. 
■For S-video, use the S-video cable supplied with your video device 
or order one from Epson. See page 24.
■For RGB video, use the VGA computer cable included with the 
projector. See page 25.
■For component video, you’ll need a component video cable. You 
can purchase one from Epson; see page 26.
After connecting your video device to the projector, you may want to 
connect an audio cable to play sound from your video equipment 
through the projector’s built-in speaker. See page 27 for instructions.
note
The projector does not 
support TV antenna cable 
F connectors. However, you 
can project TV images if you 
use a VCR as a tuner.

Playing Sound Through the Projector
The projector has a built-in speaker with a maximum output of 5 W. 
You can play sound from your video equipment through the 
projector’s speaker if your video device has an audio output port.
For RCA-Style Audio Output Ports
Most video devices have an RCA-style audio output port. In this case, 
use the audio adapter supplied with the projector to connect the 
projector to a commercially-available A/V cable, as shown below:
1. Locate the audio adapter that came with your projector.
2. Connect the black audio plug on one end of the adapter to the 
Audio jack corresponding to your video source. For example, if 
you’ve connected your video device to the projector’s 
Video port, 
connect the adapter to the 
Audio jack next to it.
3. Connect the red and white plugs on the other end of the adapter 
to the red and white plugs on the A/V cable.
4. Connect the red or white plug on the other end of the A/V cable 
to the corresponding color-coded audio output port on your 
video source.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 30 for instructions.

Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1. Then turn on your 
projector, as described below.
If you turn on your connected computer or video equipment before 
starting the projector, the projector automatically detects and displays 
the image source. If you turn on the projector first, or have multiple 
pieces of connected equipment, you may have to select the image 
source manually. See page 32.
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Push in the tabs and remove the lens cap.
2. Connect one end of the power cord to the projector’s power inlet. 
caution
Do not use the projector with 
the lens cap in place. The 
heat generated by the lamp 
can damage it.
