To
enhance the sound from your video source, you can connect the
projector to external self-powered speakers using the optical
digital audio out port. You can also connect the projector to an
amplifier with speakers.
Note: The
projector's speakers are not disabled when you connect speakers to
the Optical Out port, but you
cannot control the volume of the speakers connected to the
Optical Out port from the
projector's remote control. If you want to output higher quality
audio, set Sound Output as
Speaker/Optical (Auto) in the
projector's Sound menu.
