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 Video/Audio > Audio Setting >
Microphone Volume menu.
• Set projector volume levels in the Video/Audio > Audio Setting > Volume
menu, or press Volume keys (+, -) on the remote control. (The projector volume
setting will affect the microphone volume.)
• To make the microphone input available when the projector is in standby mode, turn
on the Video/Audio > Audio Setting > Active Audio Out menu.
• If the microphone is not working, check the volume setting and cable connection.
• You might get feedback noise from the microphone when you are too close to the
speaker of the projector. Move the microphone away from the speaker of the
projector. The greater volume you require, the greater distance you need to be
away from the Speaker to prevent the noise.
