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. Signal Parameter Min Type Max Transducer Principle Microphone Impedance 300 Frequency response 600 Dynamic 1K ohm 16k Hz • 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 Settings > Audio Volume menu, or press (Volume) on the remote control. (The projector volume setting will affect the microphone volume.) • 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. Using the cable management cover This cable management cover helps you to conceal and organize the cables connected to the back of the projector. It is especially useful when the projector is ceiling-mounted or wallmounted. 1. Make sure that all the cables are properly connected to the projector. 2. Attach the cable management cover to the back of the projector. 3. Tighten the screws that secure the cable management cover. 22
