Component video (YUV) output — Connect a cable from these three BNC
connectors to the projector for component output.
Composite video (Video) and S-video outputs — Connect a cable from the
top BNC connector for composite video output to the projector. Connect a
cable from the lower two BNC connectors to the projector for S-video output.
Mono Amplified Output (MLS 506MA only) — Cable speakers to this
output for 30 watt amplified mono audio output. This output provides a
mono signal even if the input is a stereo signal. The Audio Out captive screw
connectors ( ) can output stereo audio.
