Features: brand new and high quality It is a high and low frequency divider designed for bookcases, with the frequency division point above 200Hz. The bookcases are usually placed in a place where the room is not very big, and the distance is relatively close, and the commonly used volume is not very big. Generally, 3-8-inch bass is used, which is suitable for listen at a distance of 0.5m to 2m. The extremely strong low frequency is not pleasant to hear. In addition to an inductor, the bass lines is also connected in series with a capacitor with a capacity of about 200u. The passagee of subwoofer (ultra-low frequency) can be adjusted by limiting the capacitance. The treble part adopts two capacitors connected in parallell and the sound can be adjusted through the switches. The penetrating power of high frequency will be better than that of one capacitor, and the sound quality will be relatively delicate. A capacitor is added to the ground at the output position of the bass, so that the bass frequency can be reflected more smoothly. This frequency divider is installed on the bookcase, which shows a better low frequency, and is suitable for the performance of vocals and strings. Because there is no interference from heavy bass, you will feel that his medium and high frequencies are particularly clean and pleasant to hear, and it is suitable for being placed in bedrooms or offices, rooms and other small rooms. Between 2600-3100Hz, four frequency points can be adjusted by two switches.
