26 Playing sound through the projector This projector is equipped with a 20-watt stereo speaker system, a dedicated microphone input, and advanced audio proc essing for superb audio performance. External amplified speakers may also be connected using the audio out connector on the projector. This system has assignable audio. Audio 1, Audio 2 and/or the microphone can be assigned in any combination through the A udio Inputs feature described on page 33. Note: This system allows the mixing of the microphone audio and other audio inputs. Refer to Mic Volume in the Setup menu to adjust the mix. By default, Audio 1 plus microphone is as sociated with VGA 1 and VGA 2. Audio 2 plus microphone is associat ed with the Composite Video. 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 th e wireless microphone, it is recommended that your microphone conforms to the specifications listed in the table below. Signal Parameter MinMax Microphone Transducer Principle Dynamic Impedance 3001Kohm Frequency response 60016kHz • There are two ways to adju st the microphone volume. • Adjust the microphone volume level in the Setup > Mic Volume menu. • Press the Vo l u m e 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, th e 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.
