Connecting several video sources
If you have several video sources, connect them to an audio/video receiver or
switch box, then connect the video output from the receiver or switch box to the
projector using the highest quality connection available. Also connect the audio
outputs from all sources to the receiver, switch box, or sound system.
✎
Connect the projector’s digital audio output or stereo audio output to the
receiver, switch box, or sound system. This sends the audio from the
internal DVD player to the sound system.
