The Best Sound Presentation Method of Wireless Microphone

We often find that many users hold the wireless microphone in the wrong way. For a valuable microphone, not only can it not take advantage of the superior characteristics of the original factory, but also bury the original sound quality. The result is better than using a cheap microphone. The sound effect shown is not good.

Wireless microphones are used in many fields such as wireless microphone desktop. How to use the wireless microphone to show the excellent characteristics of the original factory, first of all, pay attention to the following basic usage methods:

1. Do not use it on the net cover of the wireless microphone

Many performers use the method of holding the microphone mesh head with their palms, which is the worst posture that seriously damages the microphone's sound quality and directivity. Using the microphone in this posture, even if the most expensive microphone is selected, it will make the original factory unique. Good characteristics, and thus lose the tone change. The result of holding the net cover with the palm of the hand is equal to isolating the sound circuit around the capsule air chamber or changing the resonance frequency of the air chamber, which will cause serious degradation of the microphone's front frequency response characteristics and the separation of the pointing characteristics, and the focus of the palm. The effect causes resonance at a certain frequency and enhances the feedback sound.

2. Grasping two wireless microphones with one hand is the most serious mistake

When two transmitters with different frequencies are used close together, it will produce harmonic interference of internal modulation distortion. The closer or the more the frequency, the more serious the interference. A system that uses multiple channels at the same time will cause mutual interference and poor reception. The problem of stability is more serious.

In addition to the problem of high-frequency harmonic interference when two or more wireless microphones are close together, the more serious is the audio phase and directional interference of the microphone, which destroys the original normal sound quality of the microphone. When the audio phases of the microphones are the same, the outputs of the two microphones will be added, causing the volume of the amplifier to increase and generate feedback sound.

3. Pay attention to adjusting the distance between the wireless microphone and the mouth

When using a directional wireless microphone, pay attention to the posture of holding the microphone, because the distance between the microphone and the mouth will change the sensitivity and sound quality significantly, especially because the sensitivity of the microphone is inversely proportional to the square of the distance between the mouth.
