A good monitoring system is indispensable for the studio, and the sound transmission of almost all studios is not related to the monitoring. How to choose a good monitoring system is a very important thing. This article is a brief introduction to the monitoring speakers.
The first difference is the difference between the monitor speaker and the general speaker. As mentioned above, the monitor speaker is used to check and confirm the quality of the sound, so the pursuit is not a so-called good sound, but the ability to accurately locate the sound field and accurately reflect the true frequency response. The audio speakers that are generally listened to and listened to are designed to gain or attenuate for certain frequencies, or the structure of the speakers is prone to resonance and excessive reverberation when broadcasting. This phenomenon will make the sound not completely correct, but It is possible to make the sound better and more spatial.
However, in the case of listening to the horn to pursue the concept of true original reproduction, it is actually difficult to achieve it. Subjectively, the human ear feels different degrees of frequency, and the frequency of the human ear is different at different frequencies. Each person's ear structure is slightly different, even through uniform specifications. After the weighted average operation of the sound, there will be no same sound experience in each person's ear; in terms of objectivity, the frequency response of the horn cannot reach the point where the original sound is reproduced. Further, the sound is transmitted. In the process of our ears, whether through the microphone or how high-fidelity equipment, the vibration that originally produced the sound has changed or is attenuated. Can it be called the original sound reproduction?
In fact, such problems also occur in the process of choosing a horn. It is to choose the full low frequency of Genelec or the high-frequency performance of YAMAHA and Adam. For each studio engineer, as long as you select a professional level of monitor speakers and are familiar with its frequency response, such distortion problems can be ignored in the music production process. Each speaker has its own characteristics, familiar with the advantages and disadvantages of the speaker, and to supplement the horn with technical knowledge and experience, this is a good engineer to do.
Comprehensive index of monitor speakers
1. RF anti-magnetic general household speakers when using electronic products, such as mobile phones, will cause noise and signal interference, and RF anti-magnetic means to prevent electromagnetic interference.
2. Sound Wave Guidance Technology (DCW-DirectivityControl Waveguide Technology)
It refers to the special enhancement of the directivity of the horn, controlling the range and direction of the sound wave transmission, reducing the extra reflection, so that the sound can directly enter the listener's ear for undistorted transmission. Such a technique sometimes works with the structure of the horn to reduce the diffraction, scattering and mutual interference of the sound in order to achieve the best performance. For example, the Genelec 8000 series of monitor speakers, its curved curve allows the sound to reflect to the horn, so that the sound is not directly reflected, but becomes diffuse, just like the principle of the diffuser, the rough blasting on the surface is also This is the truth. Different speaker brands use different speaker correction techniques. Some speakers use the internal loop of the speaker to correct distortion and compensate for the interference caused by reflection.
3. The demand is in the listening environment, and the monitor speakers must meet the needs of the listener. For engineers, the different characteristics of the monitor speakers are not so important, but rather the familiarity of the sound performance of the monitor speakers (this is the speaker must be the speaker of the studio monitor level), and must be ensured during the production process. The music produced by the group of monitor speakers can have high-quality performance in the general playback system and listening environment; for producers and customers, it is necessary to clearly hear the sound field positioning and music when listening to the work. The dynamic fluctuations, so you must be listening to the Sweet Spot when listening to it, whether the sound pressure of the monitor is large enough. In summary, the monitoring of the studio will be adjusted due to the different needs of the listener. Therefore, when selecting the monitor speaker, it is also necessary to consider the location of the speaker and the spatial acoustics, and consider the different needs of the user.
4. Acoustic Treatment and Frequency Response
A good monitoring system must achieve a flat frequency response as much as possible, but in fact, it is impossible to achieve a completely flat frequency response. There are too many things in the acoustic space that affect the frequency response, so the monitor speakers do not need to be like The microphone is almost as close to a flat frequency response, as long as there is not too much fluctuation in the spectrum, it can be considered a good listening environment.
To achieve an almost completely flat acoustic space on a spectrum analyzer, such acoustic space processing is quite expensive in terms of studio design. The simplest alternative is to add an EQ to the speaker to make room. Acoustics have to deal with things, but this does not solve all the problems. The adjusted EQ will produce phase shift (Phase Shift), which will cause some audio to be offset, or some audio to be enhanced and weakened. Therefore, in the absence of sufficient budget to deal with the acoustic space, the monitoring can only be made as accurate as possible through the correct monitoring and positioning and supplemented by the software and hardware of the sound field correction.
5. The distance between the speaker and the monitor refers to the distance from the speaker's pronunciation position to the human ear, and is divided into Near Field, Mid Field and Far Field Monitor according to the distance of the monitor speaker. Field, Long Through). Nowadays, the personal studio is popular. Therefore, the monitor speakers are mainly used for near-field monitoring. The advantage is that the relative sound pressure is relatively small, and the neighbors are less likely to be noisy when broadcasting, and the price is higher than the mid-field monitoring and far-field monitoring. That is, the main monitor is cheaper, which is the price that the general studio bears, but compared to mid-field monitoring or far-field monitoring, his sweet spot is relatively small, and the acoustic adjustment in the listening environment is relatively small. It will be more difficult. In the past, the studio will use midfield or far-field monitoring as the main monitor. The speaker's single unit and power are larger than the near-field monitor. Therefore, the frequency response is wider than the near-field monitor and can be played lower. The frequency, but because far-field monitoring is mostly in-wall, it needs to be set up with the studio. At present, in Taiwan's music production industry, there are few such large-scale studios. In foreign countries, many studios have gradually abandoned large and power-hungry wall-mounted monitor speakers, and changed to a smaller midfield or near-field monitor as the main monitor. On the one hand, because the near-field monitor is more suitable for the general audience. Play system.
6. There are many types of inputs for considering the monitor speakers, which can be roughly divided into analog transmission and digital transmission. Analog transmissions are mostly XLR and coaxial transmissions, and some lower-level speakers will also be transmitted using Phone Jack. Digital signal transmission includes AES/EBU, Cat5 network cable and fiber. Since digital transmission is the transmission of sound by means of a compiled code, it is less likely to be attenuated by long-distance transmission, and a program with built-in digital performs spatial sound field correction.
7.Dynamic Range
The dynamic response of the monitor speaker is larger, and it can express the dynamic response of the sound more than the general household speaker. The single and single rubber washers can also make the details of the speaker perform better. The unit of the household speaker is often too large. This results in excessive bass.
8. Expanding the expansion system of the technical horn is also an important factor affecting the sound. The general sound is usually a passive horn, and an additional amplifier must be needed to make the horn sound. The monitor speakers are divided into active monitor and passive monitor. The active monitor is the loop amplification inside the speaker. The amplifier used for passive monitor also needs to match the speaker. The impedance, tone, power, etc. need special selection. Otherwise, It will affect the frequency response of the speaker.
Automotive Connector
Automobile connector is a kind of component that electronic engineers often contact. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The form and structure of automobile connector are ever-changing. It is mainly composed of four basic structural components: contact parts, shell (depending on the type), insulator.
