1 microphones use correct method:

1 microphones to 48V power supply， if there is no sound， check the power supply power supply switch is turned on， the power indicator light is on and themicrophone， or may be power supply problems， should as soon as possiblerepair; the microphone when not in use， please send the microphone volume toa minimum， and then the power supply or words power switch to the "OFF"， so as to avoid vibration impact sound damaged reproducing equipment.

The 2 microphone "howling" in use， may be due to hand over the microphoneor microphone head too close to the speaker is caused， the answer is: reduce the volume first， open the same speaker distances， try to avoid the microphonepickup direction and speaker relative， then adjust to the appropriate volume，suggestions it is best to use headphones.

3 microphones connected with equipment， pay attention to the inserted in place， so as not to contact the voice interrupted or silent.

4 adjust the volume when remember to adjust， do not suddenly make thevolume is very large， so as not to damage the microphone.

5 play a recorded voice or music on the computer， the microphone volumeknob to adjust to a minimum， to avoid the introduction of outside sound， playingsound effects or disturbances

The 2 microphone maintenance and maintenance:

1 the correct installation and disassembly connecting line and the microphone.The XLR plug (commonly known as chuck) into the microphone， until thefastening key localization; microphone and cable separately， can hold the plug，while holding down the button pressing keys， and then pull the plug from the microphone. Do not access and separated from the operating force withoutalignment or press the button pressing key case.

The 2 microphone sensitivity， handle with care to avoid light， dropping from a height. The impact may result in reduced or even damage the microphone sensitivity.

3 don't audition for microphone forced blowing or hand flapping its head， the correct test method is aligned to speak into the microphone in a normal tone.

4 do not use the microphone should be shut down power supply.

5 do not use long-term microphone should allocate the microphone for safekeeping. The microphone should be stored in dry and clean place， avoid storage and use in high humidity areas， so as not to affect the sensitivity of the microphone and microphone sound， causing damage or loss of life.

The 6 microphone head and filter sponge not contaminated dust， dust may change the frequency response of microphone. Suggestions on themicrophone windproof sponge can play the role of dust.
