How to set the frequency divider in the audio processor

Whether it is in large conferences or various concerts, we will use more specialized audio equipment. In the audio, the tweeter unit is the horn speaker, and the woofer is the direct type and airflow type. In the internal and external sound quality output, whether it is internal frequency division or external frequency division, the upper and lower separation speakers must adopt the frequency division playback plan, which needs to be applied to the frequency divider. The role of the crossover in the audio can be roughly divided into the following characteristics:

First of all, the use of crossovers can make all kinds of speakers work in the appropriate audio range. The use of crossovers can send high-frequency signals to the tweeter, and low-frequency signals to the woofer. High and low-frequency signals go their own way. The advantages of the working frequency band of the respective loudspeakers are applied as much as possible to ensure that the loudspeakers of different working frequency bands are fully functional, so that the playback characteristics of each frequency are more balanced and divergent.

Secondly: the use of a frequency divider can restrain the cutting distortion caused by the different vibration amplitudes of the loudspeaker's diaphragm in different frequency bands. If we use a loudspeaker to produce sound in a wide frequency range, due to the limitation of the mechanical performance of the diaphragm, it is very difficult to have a very wide vibration change at the same time, which will inevitably cause the phenomenon of sound cutting and distortion, so that the quality of the reproduced sound Was affected to a certain extent. But if we use a frequency divider in the sound technology, this phenomenon may be improved.

In addition: the use of a frequency divider in the sound technology can also reduce the sound interference phenomenon generated between different speakers in the same speaker. The reason for the sound interference phenomenon at the crossover point and crossover area is very simple, due to the division of the frequency divider. The frequency attenuation rate cannot be made immeasurably large. In the crossover area, especially at the crossover point, the tweeter and the woofer will have the sound of the other's frequency band at the same time. At this time, the phenomenon of sound interference is inevitable. Therefore, the higher the crossover attenuation rate of the crossover is done, the smaller the crossover area and the smaller the sound interference from the speaker.

Audio processors are more specialized audio equipment, and in many places, we need to pay more attention to more details in the process of use, and we must have a certain understanding of audio equipment to better play its effects, so as to achieve the desired The effect that appears is the so-called best use of everything. Of course, a good audio device also needs an "audio man" who can set it very accurately!
