Does my product support external audio?

• Yes. The projector has an input for a stereo mini-jack cable (if your video source is connected to either the Computer or DVI port) and an input for an RCA-style audio cable (if your video source is connected to the Video or S-Video port or to the BNC ports).
  
  You can play sound through the projector's internal speaker, or you can attach an external speaker system.
