Connecting to External Speakers
To add sound, you can connect your video source and speakers to an audio video receiver, then
connect the receiver to the projector using one of the receiver's compatible video outputs (an HDMI
connection provides the best image quality, if available). You can also connect speakers to any video
source that has its own speaker connections.

Connecting to a Trigger Out Port
You can connect your projector to external devices such as motorized screens that support a trigger
signal. When active, a 12V signal is sent to the connected device while the projector is powered on.
1. Connect a 3.5 mm stereo mini-jack cable to the external device's trigger port. See your device's
documentation for details.
