Eight elements for choosing a professional audio system!.Audio brand bar

　　Professional audio and civil audio both aim to continuously pursue the best sound effect, but due to the difference in service areas, service objects and functions, the two also have similarities and differences. The professional audio service area is large and the number of people is large, so there are 8 elements to pay attention to in the selection:

　　1. The stage performance of the sound field

　　The spatial sense of the sound field has a great relationship with the placement of the speakers: the three-dimensional height, width, and depth of the sound field extend to the wall, and the height, width, and depth will form a front convex and a back concave, or a relatively flat, square, rectangular, or oval shape. , that is, the shape of the overall sound field space that extends up, down, left, right, front, and back. This sound field shape is a sense of space in various shapes. The best sense of space with titanium sound membranes is the feeling of space that permeates the entire listening room, which is relaxed and transparent in all directions. The sound field has a good sense of space, and even has the performance of penetrating the surrounding walls. Basically, in addition to good equipment, there must be an appropriate space size. It is difficult to achieve a perfect sense of space in a too small space.

　　The level and sense of localization of musical instruments and vocals in the sound field. The level refers to the three-dimensionality of the sounding bodies such as musical instruments in the sound field and the changes in depth or distance. The sense of localization refers to the left and right and up and down of the three-dimensional sound field of the sound field. s position. The sense of hierarchy and positioning is good, and various musical instruments and vocals have a three-dimensional sense of shape. If the sound system equipment is not good enough or the speaker placement is not good, you will not hear the sense of shape, especially if there is a deep sense of shape. The overall sound field should be formed on the stage behind the left and right speakers. If the sound rushes forward, it will be wrong, especially when the low-frequency performance rushes forward, it will feel like a heavy blow to the chest. Very uncomfortable and incorrect performance.

　　The density and weight of sound

　　In the overall sound field shape, the density and weight of the sound are related to the details of the sound and the stability of the sound field. The sound field has high stability and a strong sense of weight. . The high density of the sound is a manifestation of more details and a fuller sense of sound. The higher the density, the better the feeling of encircling or hugging the ears or the body, and it will feel as if you are on the scene.

　　3. Transparency and clarity of sound

　　The transparency of the sound field is related to the sound itself and the cleanliness of the background, and is related to the S+N/N contrast in terms of instrumentation. Good transparency, good sense of space, good clarity, sound mixing, sound paste such as interlayer fog or hazy yarn, the sound field must be relatively flat without depth, the sound image is large or even a lump, the common bass of titanium sound film is hypertrophy This is an example, or the bass is a mess. Some people think that the low frequency is powerful and self-satisfied. This is actually wrong. Listening to a live music concert should be compared.

　　Clarity is often confused with the phenomenon that the medium and high volume is too bright. The middle and high frequencies are too bright, too many, and the overall low frequency ratio is reduced, which makes the listening experience unnatural. Low frequency clarity is difficult to do well, and it can be determined from the degree of identification of the tail rhyme of the kick drum or the micro-vibration of the Double Bass string.

　　Fourth, the balance of high, medium and low frequency bands

　　The high, medium and low frequency bands of the sound can be balanced to be pleasant to the ear. Too bright (too much high frequency), especially labiodental sounds, is uncomfortable. Too dark (too little high frequency) will not be vivid, and low frequency expansion (too much) will overwhelm the theme. , and the lack of low frequency will appear as if there is something missing from the bottom plate, lack of integrity, or the mid frequency is not too strong enough, it will lack the warm and rich sweetness, and become dry.

　　5. The beauty of sound quality

　　The requirements are not only pleasing to the ear, but the music can also infect the conveyance of all emotions, such as the poetic suppleness of the spring breeze or the surging and surging heroic feelings, while the sound quality is not beautiful, it will produce a feeling of raw, cold, hard, thin and thin.

　　6. Resolution and detail of sound

　　With strong resolution, more details are possible. Generally speaking, it is difficult for a sound system to do a good job with low-frequency resolution. With more details, you can hear the micro-vibration (or pine scent) of the strings and the wood smell that the piano hammer instantly hits. , and the subsequent extension of the final rhyme and the resonance of the steel strings with the piano cavity and the piano reflector, as well as the emotional expression of the weak breath of the human voice, and the low frequency such as the instant tension and extended final rhyme when the drum skin is hit by the hammer.
