Nowadays people have a lot of opportunities to use the microphone, but not many people can really use the microphone. The so-called "useful" is nothing more than a good pickup effect, long service life and no harm to health. Let's talk about the big mistakes we often see, which are also contraindicated in our use. 1. Avoid tapping the microphone and blowing into the microphone during the test. Because the pickup part of the microphone is more precise and the parts are very delicate, it is easy to cause damage or component displacement when the microphone is blown or blown to the microphone head, which ultimately affects the sound quality. 2. Avoid the microphone leaving the sound source too far. The best distance when the microphone is picked up is about 10 cm. Some "leadership" speeches are far away from the microphone. Some singers stick to the microphone, and the sound of the pickup is too small. If the volume fader is pushed up, it will easily cause whistling; if it is too close, it will be spoken. The sound of the air is also picked up, causing a "beep" noise. 3. Avoid pulling the microphone lead when you submit the microphone to the microphone. Since the microphone has a certain weight and often pulls the lead wire, it is easy to cause the lead wire to be broken, and the plug contact is not good, resulting in a pickup failure. 4. Do not turn off the microphone power after using it. When the meeting is finished or after the singing is finished, the microphone switch should be turned off in time. At this time, the sound controller does not turn off the mixer volume fader in time: on the other hand, other noises are also picked up. Go in, and on the other hand, play some unnecessary speeches. President Bush has had such an experience and caused embarrassment. 5. Avoid sticking to the microphone and use some people to pay attention to or pursue a close-up effect. Often the mouth sticks to the microphone, but it does not know that this not only destroys the normal frequency response of the microphone, but also poses a great hidden danger to health. There are many germs on the microphone net cover. 6. Avoid using the microphone for a long time, do not exit the battery. Now the general wireless microphone or conference microphone needs battery power. If the microphone is not used for a long period of time, the battery should be removed to prevent the battery from leaking and corroding the microphone. 7. Avoid placing the microphone at random. It is a precision equipment. It should be placed in a clean, dry, non-corrosive gas or dust. It should also be handled gently. It must be avoided on the ground, otherwise it will be damaged in all likelihood. 8. For condenser microphones, avoid blind and phantom voltage. Since the capacitance of the condenser microphone needs polarization, it can work normally. Therefore, when using a condenser microphone, phantom voltage must be added. We must open the phantom power switch on the mixer, and pay attention to the voltage value and polarity. Otherwise, it will not be used normally and may cause damage.
