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.
You can also use a microphone to output the sound through the projector speaker.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)
menus. See
"Audio Settings" on page 63
for details.
The table below describes the connection methods for different devices, and where the
sound is from.
The projector can play sound if the connected RJ45 cable or USB cable carries audio signal.
There is no need to connect the audio cable when the USB Display or Network Display source
is selected.
About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
• You can use a wireless microphone as long as a wireless module is attached to the
projector’s microphone input jack and it works well with the associated devices. To
ensure a quality use of the wireless microphone, it is recommended that your
microphone conforms to the specifications listed in the table below.
• There are two ways to adjust microphone volumes.
•
Directly set microphone volume levels in the SYSTEM SETUP: Advanced >
Audio Settings > Microphone Volume menu.
•
Press MIC/VOL keys (+/-) on the remote control.
• To make the microphone input available when the projector is in standby mode, turn on
the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
• If the microphone is not working, check the volume setting and cable connection.

AUDIO OUT
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 COMPUTER 1/YPbPr 1 signal, the projector can play the sound received from
AUDIO IN 1/MIC. If you select the COMPUTER 2/YPbPr 2 signal, the projector can play the
sound received from AUDIO IN 2/MIC.
