The function of the divider
The frequency divider is also called the sound board, often installed in the speaker shell; the role of the amplifier is to the total frequency signal segmentation, the treble signal transmission to the tweeter unit, the bass signal is divided into subwoofer unit. Like the big lane on the road and small lanes and sidewalks as separate, will not make people chaos.
As the frequency divider is installed inside the speaker shell, outside can not see, a lot of finished products are given to the manufacturers save, or with a very low frequency divider, or with one or two capacitors instead. Speakers, if there is no divider, the sound of course, some clutter, professional frequency divider will make the sound quality of many speakers, high and low level of separation; the treble not only make it clear, and strictly prevent the low-frequency signal into the protection of the tweeter Not often burned out. Increase the intensity of the bass, the bass speaker can not accept the frequency divider, although not damaged, but due to the high frequency of the bass to work in the piston state, the intensity is not as good as the effect of frequency divider.
How to identify the divider bad: In addition to their own circuit design to be reasonable, the material is the coil of the copper wire is bigger and better, to use oxygen-free copper wire wound; capacitor voltage higher and better, Capacitor.
