Do not use on the network head of the wireless microphone:

The way many performers hold the wireless microphone mesh with their palms is a bad posture that seriously damages the sound quality and directivity of the microphone. Using the microphone in this posture, even if you choose an expensive microphone, will produce factory owned characteristics and thus lose modulation! The result of holding the net with the palm is tantamount to cutting off the sound circuit around the penis chamber, or changing the resonant frequency of the cabin. The frontal frequency response characteristics of the microphone and the degree of separation of the directivity characteristics will be seriously deteriorated. In addition, since the collective sound of the palm needs to resonate at a certain frequency, the reproduced sound will be enhanced. The wireless microphone has no online entanglement, it is convenient and safe to use, but users tend to inadvertently study the correct posture to grab the microphone, and grab the microphone's net at will. This use posture will make the microphone lose its original superiority. If a singer wants to use a microphone to reproduce the original sound of a beautiful singing voice, he must first learn the correct posture to grasp the microphone. The posture of holding the microphone is very simple. Just remember the important rule: whatever you take, don't get caught in Mike's net.

Grabbing two wireless mics in one hand is the wrong way to go:

In TV broadcasts, it is often found that some politicians hold two or even three wireless microphones in one hand and use them at the same time, which is surprising. This is a very wrong way to use, I don't know if this is the request of the user or the "creation" of the audio engineering company. As long as it is an electronic instruction, it can be followed. The latter expert made such an arrangement to whip three large plates!

When two transmitters with different frequencies are used, harmonic interference of internal adjustment distortion will occur, so the closer or the more frequencies, the more serious the interference, and the system using multiple channels at the same time may interfere with each other and the problem of unstable reception will be more serious .

In addition to the problem that two or more wireless microphones close together may cause high-frequency waveform interference, there will also be audio phase and directivity interference of the microphones, which will destroy the original normal sound quality characteristics of the microphones. If the audio from the microphones is in phase, the outputs of the two microphones are summed and the loudspeaker volume is raised, making the resent sound. Instead, the phase is reversed, so if you subtract the output of the mic, the volume of the amplifier will be underpowered. The directivity of the microphones also interferes with each other due to the proximity of the two microphones, exacerbating the original excellent directivity characteristics, and the decline of these characteristics is proportional to the distance between the two microphones, so users should avoid holding more than two wireless devices in one hand Microphones are used simultaneously. Volume, frequency response and directivity degradation should be avoided. Some people may think that if you take a few more, one microphone is broken during use, and the other can be used. In fact, in order to prevent abnormalities in the use of wireless microphones, it is not possible to use this "two-legged boat" method to solve the problem. This wrong use may cause more serious characteristic changes. Therefore, only This omission can be avoided by replacing "synchronize" with "replace". If you need to use multiple microphones at the same time, you need to increase the distance between the multiple microphones by more than 30 cm to reduce the change of microphone characteristics.
