Do you know what factors affect the sound quality of a professional audio system?

　　Many people buy professional audio to listen to music and watch movies. Some people buy stereos for the sake of beauty, and some for show. Not everyone has a thorough understanding of professional audio. Do you know what factors affect the sound quality of a professional audio system?

　　●Signal source

　　First of all, we must know that the function of the power amplifier is to amplify the weak level signal source and output it to the speaker, and then the sound of various frequencies is emitted by the vibration frequency of the speaker unit in the speaker, which is the high and medium we hear. ,bass. Among the units adopted abroad, the most famous one is RCF audio.

　　If there is noise (distortion) in the signal source or some signal components are lost after compression, after being amplified by the power amplifier, these noises will be amplified even more, and the lost components will not be released, so we use it when evaluating the sound. The quality of the sound source is very critical.

　　●Audio equipment

　　The selection of equipment is very important. Of course, it also depends on the audio manufacturer, or the manufacturer that cooperates with well-known foreign brands. The effective frequency of the speaker should be wide, the frequency response curve should be flat, the frequency response can reach 20Hz--20KHz, the power amplifier should have a high signal-to-noise ratio, a wide effective frequency response and low distortion. If the area is too small and the power is too high, a large sound pressure will cause too much reflected sound, making the sound turbid, otherwise the sound pressure will not be enough.

　　The power of the amplifier is 20% to 50% larger than the power of the speaker when the impedance is matched, so that the bass will be stronger, the middle and high frequencies will be clearer, and the sound pressure will not be so easily distorted.

　　●Use environment

　　Everyone knows that when there is no occupant in an empty room, high-fives and echoes are particularly loud when speaking. This is because there is no sound-absorbing material on the six sides of the room or the sound-absorbing material is not enough, resulting in reflected sound.

　　The same is true for the sound. If the sound absorption is not good, the sound will be unpleasant, especially if the sound is slightly louder, it will be very muddy and harsh. Although it is impossible to decorate your home as a professional audition room, but pay attention to the following points, you can also get good results
