How to match amplifier and speakers

1. First, pay attention to the power matching problem. In theory, the rated power of the speaker should be equal to the rated output power of the power amplifier, so that the equipment can work normally. It is recommended here that you would rather draw a big horse instead of a small horse. When conditions permit, you can choose a high-power amplifier, never choose a low-power. Under normal circumstances, at least the rated output power of the power amplifier should be greater than twice the speaker power. Although the big horse-drawn cart will cause unnecessary waste of power, the situation of the small horse-drawn cart prevents the speaker from getting enough driving power, and the entire sound system cannot play the best sound effect.

2. The second is impedance matching. The output of the power amplifier and the input impedance of the speaker should also be the same. Although there is a slight deviation between the two, it will not have a significant impact on the sound quality, but will only have an effect on the output power of the amplifier, but it must be reminded that if the speaker input impedance is much lower than the amplifier output impedance, it will cause a significant increase in distortion , In severe cases, the amplifier will be damaged. Therefore, everyone should try to choose the two consistent.

3. Finally, talk about matching damping coefficients. The so-called damping is an indicator that measures the internal resistance of the power amplifier output stage to the damping of the speaker. If the damping coefficient is too high, the sound from the speaker will become dry and not rounded; if it is low, the sound will stick together. Therefore, when you do the power amplifier configuration, you should pay attention to the damping coefficient of the stone machine between 30 and 40, and the amplifier has a high internal resistance, so it must not exceed 10.

4. The line connection between the power amplifier and the sound: pay attention to the power supply: the sound equipment must have a dedicated power supply and a standard voltage, and it must be separated from the light power supply. Pay attention to the length of the signal line: when connecting the device, try to use a shorter signal line as much as possible to save costs and reduce line resistance and interference. The quality of the speaker cable: try to use thicker and shorter full-copper special speaker cables. You must also pay attention to the positive and negative poles and avoid short circuits when connecting, especially the professional four-core or four-core speaker plugs. Small, be sure to pay attention when wiring. Pay attention to the grounding of the equipment: It is very important to correctly connect the grounding wires of all audio equipment. Good grounding can reduce the interference of the signal transmission of the equipment and improve the stability of the equipment.

However, if you want to find out the best sound quality performance of speakers and amplifiers, it is recommended that you choose Beilarly amplifiers and Beilarly speakers, and try to choose the same brand. Beilarly engineers will develop corresponding amplifiers based on the performance of their own speakers, which can technically bring out the ultimate performance of the speakers. And the sales staff of Beilarly will design a reasonable plan according to the user's site, user, and total budget.
