About the microphone input

Microphone to the projector.

• You can use a wireless microphone as long as a wireless module is attached

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.

• Adjust the microphone volume level in the Setup > Mic Volume menu.

•Press the Volume key on the keypad or remote to adjust the volume of the

projector speaker and audio out signal.

• 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

spe

aker 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 feedback noise.
