Setting up the LitePro 580
This chapter describes how to position the LitePro for optimum 
viewing, how to connect computers and video equipment to the 
LitePro, and how to power up the projector.
Getting started
1.Choose a location where you can dim the lighting.
• To use the LitePro in a well-lit room, use a special high gain 
screen, which you can obtain from your In Focus dealer.
2.Place the LitePro on a flat surface. 
3.Orient the LitePro so that its lens is at a right angle to the projec-
tion screen.
• If you want to use the LitePro’s Rear Project feature, set it up 
behind a translucent screen. See “Rear Proj” on page 28. 
4.Remove the lens cover. 
5.Plug the power cord into the LitePro, then plug it into your elec-
trical outlet.
Always use the power cord that was shipped with your 
LitePro. The LitePro accepts power from 110-120 VAC and 220-
240 VAC, 50 or 60 Hz, three-wire type grounded sources. When 
you disconnect the LitePro, always remove the power cord 
from the electrical outlet first, then from the LitePro.
It is recommended that you connect a power strip 
between the LitePro and your electrical outlet to 
protect against a power surge.

Positioning the projector
The distance from the LitePro 580 to the screen determines the size of 
the projected image. Use of the LitePro’s X1.4 zoom lens also affects 
screen size. The table below indicates the size of the screen image 
when using the maximum or minimum zoom at various distances.
Connections to the projector
The connection ports of the LitePro 580 are located on the right side of 
the projector, just below the handle. Push lightly on the panel labeled 
“Push” to reveal them. Cables from your computer or video source as 
well as cables to speakers, control devices, and low voltage powered 
equipment connect to the projector here.

Connecting a computer
Different computers require different connections. Connections to a 
Macintosh differ slightly from those to an IBM-compatible computer. 
Connections to a desktop unit differ from those to a laptop. 
The LitePro 580 works with IBM, IBM-compatible, and Macintosh 
computers that have a video RGB output port.
To connect your computer, you need the Y-shaped VGA cable. If you 
have a Macintosh, you also need the Macintosh adapters. We 
recommend that you turn off your computer, monitor and projector 
whenever you connect or disconnect cables.

Connecting an IBM-compatible laptop computer 
1.Plug the LCD connector on the VGA cable into the projector ’s 
Computer port.
2.Plug the VGA connector on the VGA cable into the laptop’s 
graphics port.
3.Tighten the thumb screws on the connectors to ensure proper 
grounding.
4.Turn on the projector and the laptop.
5.If necessary, activate the external display port. (Refer to the 
appendix of this manual for a list of activation commands.)
Many laptop computers do not automatically turn on 
their external video port when a secondary display 
device such as the LitePro is connected. Refer to your 
computer manual for the command that activates 
the external video port. Activation commands for 
some laptop computers are listed in the Appendix on 
page 67.

Connecting video equipment
When connecting your VCR, camcorder, laser disc player, or other 
video source, use the A/V cable included with the projector and the 
LitePro 580’s ports marked “Video.”
The projector also accommodates higher quality S-Video signals. A 
round, four-pin connector S-Video cable is not included with the 
projector but is usually supplied with your video equipment. If both 
video inputs are connected, the S-video input has priority. Use S-
Video connections when your video equipment is within a few feet of 
the projector. With the S-Video connection, the greater the distance 
between the video source and the projector, the more the signal will 
degrade.
The projector automatically detects the broadcast signal of the video 
input and accommodates the major broadcast systems: NTSC, PAL 
and SECAM. The projector also allows you to lock the projector to a 
specific broadcast system signal. (See “Video Mode” on page 27.) 
However, if the video signal does not match the locked broadcasting 
system, the projector won’t reproduce the video image properly.
Connect your video equipment’s audio output to the “Audio In” 
ports of either the Video source or the Computer source. If two audio 
inputs are connected at the same time, you can use the Audio menu 
to lock the projector to either of the two inputs. (See “Audio Source” 
on page 29.)

Connecting audio/video equipment
1.Plug the yellow connector of the audio/video cable into the 
“Video Out” or “To Monitor” port on your video equipment. To 
use the S-Video connection, plug the S-Video cable into the 
“S-Video Out” port. 
Your video source may also have a “Video Out” port 
for a coaxial cable connection. Do not use this to 
connect to the LitePro 580.
2.Plug the white connector of the audio/video cable into the 
“Audio Out/L” port and the red connector into the “Audio 
Out/R” port on the video equipment.
To connect a monaural signal, use only the “Audio 
In/L” and “Audio Out/L” ports and the white 
connector on the A/V cable.
3.Plug the other yellow connector of the audio/video cable into the 
“Video In” port on the projector. If you are using S-Video, plug 
the other end of the S-Video cable into the projector ’s “S-Video” 
port and unplug the yellow connector of the A/V cable.
4.Plug the other white connector of the audio/video cable into the 
“Audio In/L” port and the other red connector into the “Audio 
In/R” port on the projector.

Connecting an external sound system 
You can use an external public address system or an external self-
amplified speaker system for presentations in large halls or lecture 
rooms.
To connect the LitePro 580 to an external sound system, use an audio 
cable (3.5mm stereo mini plug), an optional accessory available from 
your In Focus dealer.
1.Plug one end of the audio cable into the “Audio Out” port on the 
projector.
2.Plug the other end of the cable into the corresponding “Audio In” 
jack on the external speaker(s).
3.Use the “Fade” feature on the Audio menu to adjust the audio 
output. (See “Fade” on page 29.)
