Haman told you eight microphone using taboo

There are many opportunities for people to use microphones, but not many people actually use them. The so-called "good" is nothing more than a good sound effect, long life and good health. Here are some of the major errors that we often see, and that is what we use to avoid them.

1 try to avoid beating the microphone and microphone to the microphone sound

Because the microphone pickup part is more precise, and the component is very delicate, tapping the microphone or microphone insufflation is extremely easy to damage or component displacement, ultimately affect the quality.

2 avoid microphone far away from the sound source too far

Microphone pick up the best distance of about 10 cm. Some of the "leaders" speech so far from the microphone, some singers with a microphone, causing the pickup sound too far too small, then if the volume fader to push up easily cause howling in the air; sound speech also picked up in a "noise pop".

3 avoid pulling the microphone lead

When the microphone to avoid pulling the microphone lead. As the microphone has a certain weight, often pull the lead, it is easy to lead to broken wire, plug contact is not good, resulting in pickup fault.

4 do not turn off the microphone power supply

In a speech or singing after, should promptly turn off the microphone switch, this time as sound engineer also failed to close the mixer volume fader: on the one hand, the other is to pick up noise inside, on the other hand also bring you some unnecessary voice broadcast. President Bush had such an experience, causing embarrassment.

5 mouth stick using microphone

Some people do not pay attention to the use or pursuit of a close effect. Often the mouth stuck to the microphone, I do not know this will not only destroy the normal frequency response of the microphone, on the health also caused a great deal of trouble, the microphone network cover is a lot of bacteria.

6 avoid long-term use without the microphone, do not exit the battery

Now most of the wireless microphone or conference microphone are battery powered. If a long time without a microphone, the battery should be pulled out, so as to avoid battery leakage, corrosion microphone.

7 avoid microphone placement

Microphone is a precision equipment, should be placed in a clean, dry, non corrosive gas or dust, should also be handled with care, be sure to avoid falling on the ground, or ten to one will be damaged.

8 for condenser microphone, avoid blindly adding phantom voltage

Since the capacitance of the condenser microphone needs to be polarized to work properly, it is necessary to apply a voltage to the capacitor microphone. We must open the power switch in the mixer, and pay attention to the voltage value and polarity, otherwise, not only can not be used properly, it may cause damage.
