How Does a Wireless Microphone Work?

  Microphones, one of the most important devices in professional stage recording equipment, have become almost the most technically representative products in the field of professional audio since the advent of Wireless microphone. After years of technological evolution, the area between wireless and cable is also almost clear. Because of its innate advantages, wireless microphones are widely used by professional singers for indoor performances, and the price of their high-end products is also staggering. The wired microphone is still stable because of sound quality recording market. As technology advances, the development of microphones today places more emphasis on the classification and multipurpose options of different locations, and the definition of wireless and wireline is increasingly blurred.

  With the development of wireless audio technology, wireless microphone has become one of the most prominent and dazzling microphone families ever since the end of last century. Professional wireless microphone high technology content, high prices and its excellent convenience makes it the highest indoor show in the lead. However, due to its harsh environmental requirements and many other factors such as price, application problems in other specialized fields such as recording and outdoor performances have been difficult to be solved. The wired microphone because of its inherent sound transmission advantages, has remained stable in half, even in recent years due to its price advantage, occupies a considerable share of indoor occasions.

  Wireless microphone portability, wired microphone excellent sound quality and stability are the biggest advantages of both. In recent years, with the development of wireless switching equipment, some manufacturers began to try to produce dual-purpose microphones, but the technical and stability needs to be improved. I believe in the near future, combined with wired and wireless dual microphones will become the trend.

  Many performers use the hand gripping the way the microphone is used, which is the most bad gesture that seriously damages the sound quality and directivity of the microphone. Using the microphone in such a posture, even if the most expensive microphone is selected, the original Good features lose tone.

How to Connect a Wireless Microphone | BOYA-MIC.COM

  Often go to KTV singing friends should have encountered such a situation: turn on the karaoke machine, pick up the Wireless microphone, immediately hear the super shrill creaking sound, and sometimes make an astonishing noise loud noise. Such a voice can not be accepted by anyone's ears. Here to introduce wireless microphone by KTV karaoke machines related issues.

  First, the problem analysis

  Encounter such a situation, some people suspect that there is a problem with the wireless microphone, in fact, not. This is because the current KTV karaoke machine or DVD radiation noise is too high, interfere with the wireless microphone receiver caused the trouble.

 

  General wireless microphone receiver at the factory, put the mute control start voltage (SquelchLevel) preset at a lower level to increase the sensitivity and increase the receiving distance, so in use it is susceptible to noise and noise output loud noise.

  Because the use of wireless microphone even at close range, its emission intensity will change with the user's mobile or environmental changes, whenever the wireless microphone to move a little distance or change some angle, the emission signal strength once low In the noise intensity, noise immediately replace the wireless microphone signal, an instant noise from the receiver output noise.

  In order to avoid noise interference, the mute control level is raised, so that the noise signal can not start the receiver. However, the sensitivity of the receiver will also become very low, so the use of wireless microphone becomes very short.

  Operators should carefully check the wireless microphone before the performance, connect the system correctly, and set up the antenna reasonably to ensure that the microphone is in normal working state. Pay attention to the following points. So as to avoid wireless microphone noiseless phenomenon during the performance.

How to Choose a Wireless Microphone System | boya-mic.com

  Wireless microphone has a variety of names: wireless microphone, wireless microphone, wireless handheld, wireless headset, wireless chest, wireless microphone system, generally will not cause any misunderstanding.

  With the development of electronic technology and the growing use of wireless microphone technology, market, applications have made great strides, the price is gradually approachable, all kinds of brands, various types of wireless microphone after another. Especially in recent years, domestic wireless microphone emergently in the middle and low-end market occupy half of the country.

  Wireless microphone from the initial simple one wireless FM transmitter and wireless FM receiver to the current use of dedicated PLL (Frequency Locked Loop) technology, has gone through about three stages.

 

  In general use, such as not far from (twenty meters within), used in meeting rooms, function rooms and other occasions, the case of small movements, you can choose quartz oscillating class, single receiver wireless microphone , Microphone optional moving coil, electret and other types, conditions permit, but also choose PLL type wireless microphone.

  In the performing arts clubs and theaters, due to the large moving range and complex receiving conditions, it is suggested to use a PLL type and a diversity receiving wireless microphone, and at the same time, a microphone or an optional condenser or moving coil ordinary microphone may be selected, As for the special requirements, but also the choice of musical instruments microphones, chorus microphone.

  In large theaters, studios and other professional requirements of higher occasions, I recommend the selection of well-known brands, the use of PLL receiver diversity wireless technology. These occasions, the number of microphones, receiving a complex environment, a wide range, should also configure the antenna amplifier, splitter, antenna and other ancillary equipment to improve the use of results.

How to Connect a Wireless Microphone

  In the past, the object of the microphone was only a singer. This part of the crowd who is in charge of the microphone will pay attention. Nowadays, many microphones are also used by those who work in the anchor industry. Therefore, many brand microphones are also more common people.

  In the microphone, the so-called "moving coil" refers to the wire coil is closely connected with the diaphragm, according to changes in sound pressure, continuous movement in the magnetic field generated in proportion to the amplitude of the sound wave current, so that the acoustic signal into electric signal.

  Since dynamic microphone can generate electric current by coil cutting magnetic field, dynamic microphones do not need to be powered, which is the biggest advantage of such microphones.

  The disadvantage of moving-coil microphones is that the diaphragm responds slowly to rapidly changing sound waves due to the influence of the wire coil.

f:id:sevenoak:20180305173102p:plain

  Dynamic microphone are often used to record the sound of electric guitar speakers and vocal recordings, which seems to have become a "tradition."

  Although many condenser microphone are designed to record live vocals, the unit price of condenser microphones tends to be high, and everyone prefers to use dynamic microphones for their work.

  The design of the Condenser microphone is based on the principle of electrostatics. The diaphragm of the microphone and the backplane form a complete capacitor unit. The vibration of the diaphragm with the sound wave causes the potential difference between the microphone and the backplane to change, so that the acoustic signal is converted For the electrical signal.

  In general, capacitive microphones have built-in amplifiers due to the weak output of the capacitor unit, and require an external 48V phantom power supply or battery to power the unit.

How to Choose a condenser Microphone for Your video?

  The other is dynamic microphone, the sound clear, weaker pickup, used for stage performances more

  Personal home, do not have to choose a professional microphone so expensive, just choose a high cost, the price of condenser microphone within 1000, different price options and contrast

  Two main options:  condenser microphone

  So, if the environment is not good, the use of dynamic microphones rather than condenser microphone is more appropriate, or even headphone electret more appropriate. In addition, dynamic microphone near effect characteristics are relatively obvious, this may be an advantage in some areas, such as "very close feeling." Some people's voices, but with dynamic microphone recording more Naiting, perhaps the dynamic performance of the microphone has a more unique characteristics.

  (1) If you are singing, in order to get the professional quality of the recording effect, of course, you can choose professional large diaphragm and medium diaphragm condenser microphone. However, the premise is that your room decoration must meet some of the recording acoustics requirements, such as can not have background noise, can not have obvious echo and so on. If the above conditions are not met, please give up the choice of professional condenser microphone. If your room does not meet the conditions, you have to choose a condenser microphone, then prepare a bit of money to renovate your room to dig.

  BY-VM01 Condenser Mini Microphone

  The BOYA BY-VM01 mini condenser Microphone is designed for recording audio while making videos, along with this mic your camera can create higher-quality audio. It designed for use with a digital SLR cameras and camcorder with a 3.5 mm (diameter) stereo mini-pin jack, and fits into compatible camera shoes, and connects to the camera via the 3.5mm mini-plug. Equipped with a cable stop which holds the cable in place to prevent noise from being recorded with accidental. Reduces vibration noise during autofocus

  (2) If you are recording voice (radio, dubbing, podcast ...), if you have a choice, you can select the voice-only gun-type small diaphragm condenser microphones, which are generally super-directional, can easily record your voice and can not be recorded easily Under the background noise. However, the effect of recording their songs is slightly inferior to that of the above-mentioned large-diaphragm condenser microphone

  (3) I suggest you choose a dynamic microphone if the condition of the room can not reach the acoustic environment in the front and the condition of the room is improved at the same time. Dynamic microphone sensitivity to environmental noise and echo is much lower than the condenser microphone. Normally, I recommend that home users choose dynamic microphones for recording, after all, not all families can easily achieve the appropriate recording acoustics. Dynamic microphone with good sound quality is not bad at all.

What does a shotgun microphone do ?

  There has always been a saying that the short gun Mike is not suitable for use in indoor recording. So I recently started to study this issue, trying to find the exact answer, to do some testing, see below:

  Shotgun microphone: The purpose of using these devices is to enhance the ability to pick up axially while attenuating side-annoying noise. In other words, let the microphone play its directivity as much as possible, in order to avoid unwanted noise and ambient sounds.

  To do this, the system must block signals in unwanted directions and postpone the input of these signals. So its operating principle is based on the phase offset effect. First of all, the system has series interference tubes of different sizes, allowing the signals in the axial direction to arrive at the same time, and forcing the signal in the non-axial direction to reach the delay time. He has many inventions, but also joined the current gun-type Mike R & D team.

  BY-VM600 Shotgun Microphone

  The BOYA BY-VM600 is a new designed directional shotgun microphone which can maximizes the sound quality.

  In the original design, in order to maintain good directivity, it is necessary to add more interference tubes to make the microphone powerful enough to cope with the work. The volume is very large and very inconvenient. Later, in order to solve this problem, the design changed to a multi-slot interference tube to replace the old-fashioned interference tube. These slots allow the sound beyond the axial reach to the diaphragm, so when it comes into contact with the sound source, the noise is greatly attenuated.

f:id:sevenoak:20180305163830p:plain

  On the other hand, the longer the microphone can be designed to make the pickup angle more narrow, so the more directivity of the microphone, more importantly, the correct axial arrangement. If we do not understand the axial.

  In an echoed space there will be diffuse, especially early reflections, the color of the signal part. Ideally, the microphone depends on the angle of the transform, if the sound is a correlated signal or just a noise. When both the signal and the noise are reflected on the nearby surface, it is an "unnatural" angle for them to enter the microphone (if we consider the sound track in the natural direction).

How to provide power to a lavalier microphone?

  Many users see TV programs that use the Lavalier Microphone to sound very well and have also used the microphone to amplify the sound in the field with less than satisfactory results. This is not the Lavalier Microphone itself quality problems, but because the microphone is worn too far away from the mouth, the microphone in the field when the microphone with the speaker system speakers produce feedback sound physics, can not arbitrarily increase the volume, so the PA not effectively.

  Reduce the distance between the microphone and your mouth to improve the sound amplification of the microphone:

  As the Lavalier Microphone worn on the chest, away from the mouth, the output volume will be greatly reduced, if the amplifier volume is large, it is easy to produce audible feedback, which is generally the microphone user often encountered problems. If you want to enhance the microphone volume, but also produce no feedback, the only way is to use the "microphone volume and the source inverse square inverse distance" principle, the microphone and the mouth of the distance closer to the microphone can be greatly louder The promotion.

  BY-LM400 Dual-Lavalier Microphone

  The BOYA BY-LM400 is a dual-lavalier microphone is designed for recording interviews. With 3.5mm(1/8") TRRS connector, it works for iPhone, Ipad and most of Android devices.

  It uses a TRRS connector to connect into your smartphone or tablet's headphone input

  And With 4m (13') Cable, the BOYA BY-LM300 can be used for presentations, podcasts, webcasts, or any situation where more than one subject needs to be recorded.

  Adjusting the position of wearing the microphone and adjusting the sound head at the position of "near both the left and right of the mouth" can reduce the noise of the gas explosion and obtain the desired sound volume and normal sound quality.

  Headphones used in the headset are: omnidirectional and unidirectional two, the former, because the first non-directional head, when worn as long as the "tune the sound on both sides of the mouth, from the mouth about a finger distance, And close to the mouth perpendicular to the direction of ", you can obviously avoid gas explosion noise, to achieve the clearest sound.

   After the actual test, "the microphone head and mouth to keep the front of a finger about the distance between the mouth and keep a 45-degree horizontal direction" is the ideal position to wear, to avoid the destruction of gas explosions, but also to show Optimum sensitivity and sound quality, if the sound head position than the front corner of the mouth, by the impact of the sound of the explosion will be greater, although the use of windshields such as sponge, you can slightly reduce the impact of air noise and wind noise, but how much Will also undermine the face of view and attenuation of the high-frequency response of the microphone.
