Connection 26
Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also
connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output
of your Video source device to that sound system, instead of to the mono audio projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)
menus.
The table below describes the connection methods for different devices, and where the
sound is from.

The selected input signal determines which sound will be played by the projector speaker, and
which sound will be output from the projector when AUDIO OUT is connected. If you select the
PC signal, the projector can play the sound received from AUDIO IN mini jack. If you select the
COMPONENT/VIDEO signal, the projector can play the sound received from AUDIO
(L/R).
