Connecting to a Video Source for Sound

If you connected external speakers to the projector, you can connect your video source to the projector with an audio cable to play sound.
Note: If you connected your video source to the projector's SDI port (Pro L1490U/L1490UNL/L1495U/L1495UNL/L1500UH/L1500UHNL/L1505UH/L1505UHNL/L1750UNL/L1755UNL), audio output is not supported.
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 have problems hearing audio through the HDMI connection, you can play sound through an audio cable instead by following the steps described here.
  1. Connect one end of a 3.5 mm stereo mini-jack audio cable to your video source's audio-out port.
  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. If you are projecting video through the projector's HDMI port, connect the end of your audio cable to the Audio3 port.


Note: If you connected to the Audio3 port, select Audio3 for the HDMI Audio Output setting in the Extended menu.
