The next is the difference between a wireless microphone and a wired wireless microphone! And wireless microphones certainly better than wired!
Second: the working principle of the best wireless microphone for singers classification (1) Dynamic Wireless Microphone This is a familiar noun. Basically, everyone at home are moving coil wireless microphones. The basic structure contains the coil, diaphragm, permanent magnet three parts. When the sound waves into the wireless microphone, the diaphragm is vibrated by the pressure of the sound wave, and the coil connected with the diaphragm starts to move in the magnetic field, generating sound signals according to the moving magnetism.
Dynamic wireless microphone because it contains a coil and magnet. You see a thin film attached to itself hundreds of times more than the magnet, the sensitivity will certainly not be too high, low frequency response poor performance. But the advantage is that the price is cheaper, the sound is more gentle, suitable for recording human voice. And it does not support the special equipment requirements, is the first choice for home wireless microphones.
Condenser Wireless microphone capacitive Just look at the picture, you can find the capacitive is much simpler. The condenser wireless microphone does not have coil and magnet, rely on the change of the distance between the two plates of the capacitor to produce the voltage change. When the sound waves enter the wireless microphone, the vibrating membrane vibrates because the substrate is fixed so that the distance between the vibrating membrane and the substrate changes with vibration and the capacitance value changes. For popular science articles, each introduction of a formula will drive away half of the readers. But to explain the Phantom Power behind, I had to introduce a formula: Q = C * V (Q: battery, C: capacitor, V: voltage)
As mentioned above, the condenser wireless microphone changes the capacitance C due to sound vibrations, so if we want the voltage V to reflect the change of C and produce an electrical signal, we have to maintain Q (charge) unchanged.
Well, I’m really sorry, should not introduce a formula. In fact, we do not need to know this. All we have to keep in mind is that in order to maintain this power (Q) constant, all condenser wireless microphones require an additional phantom power, which is usually +48 V.
Some condenser wireless microphones come equipped with Phantom Power, but most condenser wireless microphones require +48 V phantom power through the XLR cable. The power to produce fantasy Mic Preamp can also be a Mixer with Mic Preamp. XLR line length this way:
condenser tube wireless microphone Condenser Tube Wireless microphone audio tube, southerner called “gall.” So vacuum tube amplifier is also called “tube amplifier.” The Tube Preamp feels the warmth of the sound with its gentle, moderately distorted distortion. Foreigners only use one word to describe: warm. I use the image of a word to describe: Tsai Chin.
In the studio-class high-end products, there are condenser tube Wireless Microphone Condenser. This type of wireless microphone is actually the “tube amplifier” to go inside the wireless microphone. This is a “tube” called the Mallard 12AT7 So for this type of wireless microphone, the + 48V phantom power is not enough. So a separate power supply is needed to power the condenser vacuum tube wireless microphones separately. This power supply is called Steady Power Supply. The wireless microphone is connected to the XLR 7pin, which is 7 holes instead of 3 holes. But in the power, there is a 3-hole output, you can put the wireless microphone signal through the 3-hole connection, the output to the Mixer.
This Power Supply Is Usually Bundled With A Condenser Vacuum Tube Wireless Microphone.
The difference between the “Large Diaphragm” condenser wireless microphone and the “Small Diaphragm” condenser wireless microphone. Large Diaphragm refers to a larger condenser wireless microphone with a sensing membrane. This type of wireless microphone is suitable for Vocal as well as for normal instruments, while “Small Diaphragm” condenser wireless microphones are often used for recording instrument performance. A number of “Small Diaphragm” wireless microphones are sold in pairs for the purpose of separating left and right channels for the recording of stereo effects.
You should be careful not to think that buying a pair of stereo “Small Diaphragm” wireless microphones will pick up the sound as two wireless microphones, which will be less effective than a large diaphragm wireless microphone. And “Small Diaphragm” (Small Diaphragm) is usually used for recording instruments.

Three: Wireless microphone an important indicator: Responsiveness (frequency response) Frequency response refers to the wireless microphone to accept different frequency sound, the output signal will occur as the frequency change amplification or attenuation. The ideal frequency response curve is a horizontal line, representing the output signal can be straight to show the original sound characteristics, but this ideal situation is not easy to achieve. In general, the frequency response of condenser wireless microphones will be smoother than the moving coil. Common wireless microphone frequency response curves are mostly high and low frequency attenuation, while the high-frequency slightly enlarged; low-frequency attenuation can reduce the recording environment around the low-frequency noise interference. As can be seen in the figure, the frequency response of the condenser wireless microphone (upper) is better than that of the moving coil (lower)
This figure is the response of a high-quality condenser tube wireless microphone. The frequency response has been quite perfect.
Of course, there are other working wireless microphones, there are some technical indicators such as resistance, but if we discuss these 108 kinds of purely fennel beans to eat, to show off the knowledge of people in addition to the brick or brick.
So in the final analysis, moving coil with capacitance, which kind of better? There is an old saying when choosing a spouse: it’s best for you. The same applies to you to marry a wireless microphone: what occasion to do with what, is the best.
Children at home who have a tendency to violate the wireless microphone may not be able to withstand the squeamish capacitance of his / her tossing; rock musicians who like to kiss their wireless microphones up close, the dynamics may be more saliva. If the home environment is noisy, just want K song fun, then the dynamic is still your first choice. Do not know is not true, Shure SM 58 wireless microphone is said to be the most able to withstand the frustration of the world’s wireless microphone.
If you want to create a studio with a higher definition then a condenser wireless microphone is a must; consider the condenser tube wireless microphone if you are passionate about recording quality and less budget-conscious.
Well, finally, talk about wireless microphones and wired wireless microphones. Many people say: “My home karaoke OK upscale, and is wireless!” This is not your fault, this is the fault of business hawkers. Ninety-nine percent of small video stores are selling karaoke machines, and their knowledge of the wireless microphones is limited to the distinction between wired and wireless, then advertised at low prices for wireless microphones.
