7 techniques used by microphone

　　1. Don't be too close to the microphone

　　Too close to the microphone is a common habit of many people. It feels so well and can enlarge the sound. In fact, too close to the microphone will destroy the normal frequency of the microphone, and there may be a lot of bacteria on the microphone's net cover, which will threaten the body's health.

　　2. Do not pat the microphone or blow it in the microphone

　　Is it surprising? Intersection Will this action be seen on many occasions, this small action is the habit of many people. The pickup part of the microphone is more precise and more expensive. Taking a microphone or blowing the microphone can cause the displacement and damage of the microphone component.

　　3. Do not place the microphone at will

　　Although the microphone is small, the parts inside are very precise. The microphone should be placed in a place where it is dry, clean, no corrosive gases or dust, and pay attention to it. You must put it lightly. Therefore, the microphone placed in the KTV private room is in the dark environment for a long time, it is easy to "ill". It is necessary to take out the microphone out of time "breathe fresh air".

　　4. For capacitive microphones, do not blindly add illusion voltage

　　The capacitance of the capacitance microphone needs to be polarized to work normally. Therefore, when using a capacitor microphone, an illusion voltage must be added. We must turn on the phantom power switch on the tuber, and pay attention to the voltage value and polarity at the same time. Otherwise, not only cannot be used normally, it may cause damage.

　　5. Do not leave the sound source too long or too close

　　The best distance at the microphone is about 10 cm. Some "leadership" speaking is far from the microphone, some singers are stuck in the microphone, and the sound of picking up is too small. The sound of the air flow also picked up, and the sound of "噗" was made.

　　6. When the microphone is not used for a long time, please remove the battery

　　Nowadays, wireless microphone or meeting microphone requires battery supply. If it is not used for a long time, the battery should be removed to prevent the battery from leakage and corrodes the microphone.

　　7. After use, please turn off the microphone

　　At the meeting or after the singing, the microphone switch should be turned off in time. At this time, if the sound controller also did not turn off the tuning tabletop push in time: on the one hand, the other noise was picked up, and on the other hand, it was easy to play private voice. President Bush once had such an experience, which caused embarrassment.
