Using the audio

Using the projector’s speakers

Connect the audio source to the Audio 1, Audio 2, or Audio L/R connectors to hear

audio through the projector speakers. You may use the projector’s speakers by

connecting a microphone to the Microphone input connector.

Amplified speakers may also be connected to the projector

using the Audio Out

connector.

To adjust the volume, press the Vo

lume buttons on the remote.

Troubleshooting Audio

If you aren’t hearing the audio, check the following:

• Make sure the audio cable is connected to the

Audio In or Audio L/R

connectors on the projector, and that the other end of the cable is connected to

an Audio Out connector on the source (not a “line-in” or “microphone”

connector).

• Make sure the volume is turned up enough. Press the Vo

lume button on the

remote.

• Make sure the correct source is active.

• Adjust the audio source.

• If playing a video, make sure the

playback has not been paused.
