Connecting to a Video Source for Sound

You can play sound through the projector's speaker system if your video source has audio output ports (Pro L1100U/L1200U/L1300U). Just connect an optional stereo mini-jack audio cable as described here.
Note: If your projector does not have an internal speaker system (Pro L1405U/L1500U/L1505U), you can play sound by connecting external speakers to the projector.

Note: If you connected your video source to the projector using an HDMI cable, the audio signal is transferred with the video signal; you do not need an additional cable for sound. If you connected your video source to the projector's SDI port (Pro L1405U/L1500U/L1505U), audio output is not supported.
  1. Connect the audio cable to your video source's audio-out ports.
  2. Connect the other end of the cable to the projector's Audio port that corresponds to the Computer or BNC port you are using for video.
