About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable Dynamic
Microphone to the projector.
• You can use a wireless microphone as long as a wireless mo
dule 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.
Signal Parameter Min Max
Microphone Transducer Principle Dynamic
Impedance 300 1K ohm
Frequency response 600 16k Hz
• There are two ways to adjust
the microphone volume.
• 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.
• The microphone will work regardless of whether the projector is turned on or
soft-powered off, if the Always-On function “Microphone” is set to On.
• 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 feedback noise.
NOTE: Only Dynamic Microphones should be used. Do not use active (phantom-
powered) microp
hones as projector damage may occur.
