Installing the projector
Choosing cables
If you are permanently installing the projector or using it with long cables, consider the
following suggestions when planning the installation:
• Use high-quality cables. Use only video cables that are made with 75-ohm coaxial cable
and connectors. For high-resolution video, use low-loss video cables. For standard audio,
use audio cables that are shielded. For digital audio, use 75-ohm coaxial cables.
• Minimize cable length as much as possible. For video cables longer than 6 m (20 ft), use
low-loss coaxial cables. For standard audio cables longer than 6 m (20 ft), use 12-gauge
wire.
• Do not run audio or video cables next to power or network cables. If they must cross, cross
them at 90 degrees.
• If you are installing cables in walls, use cables with necessary approvals, such as
Underwriters Laboratories (UL) approval.
• If you are running cables above a dropped ceiling, you must use plenum-rated cables if the
space above the ceiling is open to the space above other rooms. You must use plenum-
rated cables if you are running cables in a duct.
• Before installing cables permanently, check the setup with the final cables in the open.
