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 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.
Signal Parameter Min Max
Microphone Transducer Principle Dynamic
Impedance 300 1K ohm
Frequency response 600 16k Hz
• There are two ways to adju
st the microphone volume.
• Adjust the microphone volume level in the Setup > Mic Volume menu.
• Press the Vol ume 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 micr
ophone 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) microphones as projector damage may occur.
