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
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 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.
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.
