How does a wireless microphone work? A wireless microphone consists of multiple pocket transmitters (which fit inside a pocket with an output power of about 0.01 w) and a centralized receiver. Each pocket transmitter has a different operating frequency, and the centralized receiver can receive sound signals from each pocket transmitter at the same time with a different operating frequency. The following booklet describes the proper use of the wireless microphone method.conference speaker with mic: A Must-Have for Meeting Rooms
Do not use on the wireless microphone head;
Many performers, with the palm of the hand grasping the microphone head of the use of management, is a serious impact on the destruction of the microphone sound quality and directionality of the most undesirable behavior posture, in such a posture to use based on the microphone, even if we choose the most expensive microphone, will make the loess factory has the best characteristics, and therefore the loss of corporate tuning! The result of holding the mesh head with the palm of the hand can be equal to the social isolation of the sound system circuit around the air chamber of the sound head or change the resonant working frequency of the air chamber, which will lead to a serious deterioration of the frontal appearance of this microphone frequency change response time characteristics and pointing to different characteristics of the separation, and the analysis of the polyphonic effect of the palm of the hand caused by the resonance of a section of the student’s frequency and enhance the development of the back teaching sound generated. Although through the wireless microphone because they do not have the network on-line entanglement, the use of more convenient information security, but for the user needs often do not learn to study the correct posture of holding the microphone, arbitrarily grasping on the microphone’s mesh head, such use of various postures, will certainly gradually lose the superior environmental characteristics of the microphone loess. A singer needs to use the microphone to reproduce the beautiful voice of the loess, you must first learn to hold the microphone in the correct position. The posture of holding a microphone is very simple, as long as you can remember yourself a very important guideline: no matter how you hold it, people should not grasp on the microphone’s mesh; the correct posture during use should be held on the microphone’s tube body.
Holding two wireless microphones with one hand is the worst practice:
On TV shows, it is common to find politicians who are very surprised to hold two or even three wireless microphones in one hand to use the camera. This is a very wrong way to use the camera. I don’t know if this is the request of the user or the creation of the sound engineering company. If the former instruction is justifiable, if the latter professionals have made such an arrangement, they should be whipped three boards.
Because will be two aspects of different operating frequencies of the transmitter close to use, will produce internal tuning distortion harmonic interference, the closer or more and more frequencies, the more serious interference, in multiple channels can be used simultaneously through the system, will make the students affect each other interference and unstable reception ability of the problem more serious.
Two or more wireless microphones together will not only produce high-frequency harmonic interference, but also produce microphone audio phase and direction interference, destroying the normal sound quality of the microphone loess.
