Connecting to External Speakers
To enhance the sound from your video source, you can connect the projector to external self-powered
speakers. You can control the projector's output volume using the projector's remote control.
You can also connect the projector to an amplifier with speakers. This bypasses the internal speakers.
1. Make sure your computer or video source is connected to the projector with both audio and video
cables as necessary.
2. Locate the appropriate cable to connect your external speakers, such as a stereo mini-jack-to-pin-
jack cable, or another type of cable or adapter.
3. Connect one end of the cable to your external speakers as necessary.
