Using a Switch Box
You can use a switch box or control box to connect various video inputs to the projector. However, the primary
computer should always be connected directly to the projector with a USB cable for interactivity and another
cable for video output (VGA, HDMI, or Ethernet). This allows maximum interactivity and dual pen support
(using Easy Interactive Tools software) for the computer. The projector's built-in toolbar will be available for
images from equipment connected through the switch box.

Connecting Video Equipment

You can connect various video devices, such as DVD players, satellite/cable systems, VCRs, or game systems.
Depending on the connectors available on the equipment, you can use any of the projector ports in the
following list. The projector ports are listed in order from highest to lowest quality; if your equipment has
multiple connectors, choose the one that provides the best quality image.

Connecting Audio

A variety of audio connections are available:
•
You can connect a dynamic microphone to the Mic port and output the sound through the projector.

You can also output computer audio. If you connected the computer using a VGA cable, you need to
connect an optional 3.5 mm stereo mini-jack audio cable for sound. If you are using more than one audio
connection, label the cables Audio1 or Audio2.
•
If you connected the computer using an HDMI or Ethernet cable, you can output both video and audio
through the cable.
•
To enhance the sound from your presentation, you can connect the projector to external speakers with
built-in amplifiers. The volume can be controlled using the projector's remote control.
