About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
• There are two ways to adjust microphone volumes.
• Directly set microphone volume levels in the SYSTEM SETTING: ADVANCED
> Audio Settings > Microphone Volume menu.
• Set projector volume levels in the SYSTEM SETTING: ADVANCED > Audio
Settings > Audio 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 SYSTEM SETTING: ADVANCED > Audio Settings > 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.
