How are condenser microphones used

  What is the difference between ordinary microphone and professional microphone?

  What's the difference between the types of microphones?

  The common microphones can be divided into dynamic Microphone, condenser microphone (Condenser Microphone) and Ribbon Microphone depending on the working principle.

  Non-professional occasions to see is the most dynamic microphone, and you go to KTV singing is basically a dynamic microphone.

  The principle of dynamic microphone: The diaphragm in the microphone head drives the coil to vibrate and cut the magnetic line to generate electrical signal, which is transmitted to the next device through the microphone line.

  The advantages of dynamic microphone: the structure is simple, durable, lower prices, the use of the environment is not demanding.

  However, compared with the condenser microphone sensitivity is not high enough (is a disadvantage, but also advantages, as will be mentioned later), high-frequency response is not enough, the sound is not delicate enough.

  BY-PVM50 Condenser Microphone

  The BOYA BY-PVM50 is a stereo X/Y condenser microphone with compact body and lightweight for easy use, which specially designed for DSLR cameras, Camcorders, Audio recorders etc.

  Condenser microphone is the most widely used professional recording area, you hear the song in the album, 99% are condenser microphone recording.

  Condenser microphone principle: with a very thin metal diaphragm as a capacitor level, another close to the metal backplane (about a few millimeters) as the other pole, so the diaphragm vibration will cause the capacitor capacity Changes in the formation of electrical signals.

  Condenser microphone advantages: Because the diaphragm is very thin, so a very small voice can make it vibrate, so condenser microphone is very sensitive.

The Best Condenser Microphones for Pro & Home Studio

  The microphone is a very personal item to the musician, and there are often many factors to consider when making the selection. In a wide range of microphones, there is no such thing as "a microphone is the best." Each type of microphone has their own unique properties and uses, resulting in different sound quality.

  Dynamic microphone

  The meaning of "moving coil" is that the coil of the coil, which is closely connected with the diaphragm, moves continuously in the magnetic field according to the change of sound pressure to generate a current that varies proportionally with the amplitude of the acoustic wave, so that the acoustic signal is converted into an electrical signal.

  Dynamic microphone cutting coil magnetic field directly to the current, so dynamic coil wheat does not need power supply. Dynamic microphone's advantage is its simplicity and skin. The disadvantage is that because of being "dragged down" by the wire coil, the diaphragm does not respond as rapidly to changing sound waves as other types of microphones.

  Moving the Microphone to Pick up Elaborately-charged, high-frequency components can be tough, but dynamic microphones can provide satisfying performance when picking up the bottom drum or snare sound. Dynamic microphones are also often used to record the sound of guitar amps.

  Dynamic microphone is often used for vocal recording, which is largely a "traditional custom." As the previous condenser microphone was stupid and fragile. But even though condenser microphones are now designed for live vocals everywhere, their more expensive, uniform prices tend to make people more inclined to choose dynamic microphones that work equally well.

  Small diaphragm condenser microphone

  Condenser microphone is based on the principle of electrostatic design, the diaphragm and the back plate to form a capacitor unit, the diaphragm vibration with the sound caused by the potential difference between the backplane and change, so that the acoustic signal into electrical signals. condenser microphone usually built-in amplifier, the output of the capacitor unit is very weak. condenser microphone Requires 48 V phantom power supply or battery.

Why and When to Use a Stereo Mic on a Camera

Stereo microphone is a process of recording multiple soundtrack tracks during film production. The signal-to-noise ratio, dynamic range, bandwidth, distortion, and crosstalk and phase shift of the main soundtrack material of the movie stereo are all stricter than those of the mono video. Recording system that digital video camera audio system. Most of the digital camera recording system for the PCM stereo digital recording system, optional 12-bit (recording frequency of 32KHz, two-channel) and 16-bit (recording frequency of 48KHz, two-channel) two different modes of recording. Let's take a look at the recording technology of a digital recorder.

Stereo recording on a digital recorder has a cross-shaped microphone shape that is much more complex than we thought to be with mono recording.

Recording dual-channel stereo, the main difference between time and sound pressure to create a three-dimensional sense of space, the time difference is the sound source to reach the left and right ears of different time and produce three-dimensional sense of sound pressure is different from the ear to receive the sound intensity and produce three-dimensional.

  BY-V02 Stereo Condenser Microphone

  BOYA BY-V02 is a stereo condenser microphone,for use with DSLR cameras, camcorders, and audio recorders, it features cost effective is an ideal for video use. The BY-V02 measures 5.94" (151mm) in length and includes a dead kitten windscreen, camera hot-shoe mount, and replaceable rubber O-rings suspend the microphone on the shock mount and protect against noise due to movement and handling.

For stereo recording, there is another important factor is the phase. When using speakers or mixing left and right channels into mono, the same phase of the left and right channels increases the volume, but decreases the volume. Active noise reduction devices used in aircraft and some cars reduce noise by outputting sounds of opposite phases.

Stereo microphone placement (also known as standard) is very complicated, commonly used are the following:

A / B mode: two microphone pulled apart, parallel or at a certain angle toward the sound source. Simple but easy to produce sound field and phase problems.

All of the songs and pure music we hear are recorded by a microphone. Simply speaking a microphone represents a mono. General recording with multi-track vocals and various instruments, the resulting music is stereo.

What wireless microphone setups work with SlingStudio?

  The directivity of a microphone means that the microphone picks up sound from different directions. In the field setting, the most important thing is to confirm the type of microphone you are using, thereby reducing the feedback of the sound and the use of directivity where it is the best place to place the monitor. In the studio, you can make changes using sensors with different characteristics. It's like arranging certain decorations when recording or near the effect.

  BY-VM190P Super-Cardioid Microphone

  The BOYA BY-VM190P has a super-cardioid pickup pattern to capture audio from the front, while minimizing pickup from the sides and rear. It’s compact and lightweight design with a rugged construction that's ideal for use with HDSLR cameras, camcorders, and audio recorders.

  Cardioid: Only picks this direction facing the microphone

  This is the type of microphone most often seen by singers. Often described as having a cardioid pattern, it is often used in studio recording vocals. In situations where you do not want to pick up the audience's voice or the sound that comes out of your monitor, a heart-shaped microphone works well in this situation (with a heart-shaped microphone the monitor should be placed opposite you and you are 180 degrees ).

  Super-Cardioid Microphone

  Such directional microphones are becoming more popular on the spot, such as the Shure Beta 58 or the TC-Helicon MP75, which are better at capturing vocals on stage and blocking the sound of the surrounding band. The downside is that it also contains some of the sound behind the microphone. This means that you should not put your monitor in front of you (usually 120 or 240 degrees is best) or you will hear an echo. Super-heart-shaped microphones are usually used in the studio, when you need to maximize the isolation of other voices, rarely used to record voice.

  This type of pointing is very similar to that of heart-shaped pointing and is often confused, however, and the general orientation of supercardioid types is slightly less than that of heart-shaped ones, and their sensitivity to the sound coming from the rear of the microphone is also small Much more.

How to find the right wireless microphone?

KTV's microphone quality affects the consumer's most direct consumer experience, the microphone quality is good, consumers are willing to sing often to put pressure on the record, but if the microphone is often a problem, people came once again will not want to come. There are many KTV owners are complaining about the damage rate of private room microphones too high.

In fact, as long as the correct choice and use of Wireless microphone can extend the life of the microphone, we use the microphone in everyday life to avoid some taboos, but also can be well maintained microphone.

①, bogey and microphone "kissing"

And the microphone "kissing" is the habit of many people, some people think holding the microphone intimate close to the mouth singing singing handsome. In fact, sticking to the microphone with his mouth destroyed the normal frequency response of the microphone, the health of their own body is not good, there are a lot of germs microphone grille.

②, avoid tapping the microphone or blow into the microphone

To see this, I believe many people are staggered, this little trick is too many people's habits. Microphone pickup part of the more sophisticated, and not quite see the more expensive, patting the microphone or the microphone blowing are likely to cause displacement of microphone components or damage.

 

 

Since the capacity of the condenser microphone requires polarization to work properly, the phantom voltage must be applied when using the condenser microphone. We must open the phantom power switch in phantom, at the same time pay attention to voltage and polarity, otherwise, not only can not be used normally, may cause damage.

Best Shotgun Microphones for DSLR Video Cameras

  According to the internal structure of the microphone can be divided into two kinds of dynamic microphone and Condenser microphone, the former principle is to use sound waves to promote the diaphragm, and then shock film driven coil, the use of changes in magnetic lines have a weak voltage. This microphone is the most common microphone on the market, the general arena or hand-held microphone is the majority of this, it does not need external power supply can be inserted directly into the speaker system pronunciation, because this microphone is more portable , The frequency response is not bad, so the popularity is high;

   So you will see that some wired microphones require a battery pack and others have to rely on the virtual power supply on the mixer so if you buy a condenser microphone, remember to check if your mixer is supported it. Often recording studios tend to use condenser microphones for radio reception because of their high sensitivity and generally better dynamic and frequency response than moving coils. However, if the studio soundproofing is not good enough, you will find that Condenser microphone instead is a bother.

  Condenser microphone outperforms moving-coil microphones in terms of sensitivity and extended high-frequency (and sometimes low-frequency) response.

  This is related to the working principle that the condenser microphone needs to convert a sound signal into a current first. In general, condenser microphones are very thin and easily vibrated by sound pressure, causing a corresponding change in voltage between diaphragm and diaphragm back panel. And this voltage change will be followed by preamplifier multiples of amplification, and then converted into sound signal output.

  BY-VM600 Shotgun Microphone

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

f:id:sevenoak:20180301164833p:plain

  The "preamplifier" used here refers to an amplifier built into a microphone, not what we commonly refer to as "pre-amp", the preamplifier that comes with the console or interface. Due to the very small area of ​​the condenser microphone diaphragm, its response to low-frequency or high-frequency sound signals is very sensitive. Most condenser microphone are capable of accurately capturing the sound signals that many people can not hear at all.

  In contrast, moving coil microphone works much simpler. It produces sound signals primarily through the movement of conductors in a magnetic field. In fact, the dynamic microphone microphone sound signal generated, mainly through the coil is closely connected to the wire coil according to changes in sound pressure in the magnetic field to complete the movement. Due to the relatively large volume of the moving part, the dynamic microphone is inferior to the condenser microphone in response to the frequency range (mainly the high frequency part), sensitivity and instantaneous response capability.

How to choose a good wireless microphone?

  A,Why Wireless microphone frequency

  One reason: the launch power is less than 50 milliwatts (state regulations), while the radio is more than ten thousand watts.

  Two reasons: the external signal interference and its own signal reflection signal interference, as shown: wireless microphone direct signal is A, when he is reflected by the signal B and outside interference signal C, will be out of frequency.

  Second, to solve the frequency of the method:

  1, choose to launch a larger power, as long as no more than 50 milliwatts is not illegal.

  2, the choice of dual-antenna above the receiving method: an antenna interference and there is another antenna to receive, that diversity reception technology.

  Third, how to choose a good diversity receiver wireless microphone.

  1, diversity reception and non-diversity reception of the discrimination method:

  Open the dual-channel receiver, if you unplug the left antenna, holding the left channel microphone to five meters away there is no signal is non-diversity; the contrary is diversity.

  2, the type of diversity reception: antenna diversity reception and true diversity reception.

  (1) Antenna Diversity Reception: The antenna signal is strong, and the antenna receives the signal. However, there will be a short period of antenna frequency conversion, such as the issue of "pop" "pop" noise.

  (2) true diversity reception: two antennas are to receive and demodulate the signal, then select a good audio signal to use.

  So, the most stable receiving system is: true diversity receiver wireless microphone !!!
