150W Speaker Crossover Divider Double Tweeter Board

Description

Product Description
The frequency divider is also called the sound splitting board, which is often installed in the speaker shell; its function is to divide the total frequency signal from the power amplifier, divide the treble signal to the tweeter unit, and divide the bass signal to the woofer unit. Just like the big lane and the small lane and the sidewalk on the highway, it will not make people and vehicles confused.
Since the frequency divider is installed in the speaker shell and cannot be seen from the outside, many finished speakers are saved by the manufacturer, or use very low-end frequency dividers, or use one or two capacitors instead. If the speaker does not have a crossover, the sound will of course be messy. A professional crossover will make the sound of the speaker clearer, and distinguish the high and low levels; not only make the treble clear, but also strictly prevent the entry of low-frequency signals and protect the tweeter unit Not often burned out. To increase the power of the bass, the woofer can not be connected to the crossover, although it will not be damaged, but due to the entry of high frequency, the bass works in the piston state, and the power is not as good as the effect of the crossover.
How to distinguish the quality of the frequency divider: In addition to the reasonable circuit design, the material used is that the larger the copper wire of the coil, the better, and it should be wound with oxygen-free copper; the higher the withstand voltage of the capacitor, the better, and the non-inductive capacitor should be used. .
Product parameters:
Brand
: LI WEI.
Model
: MTV-210B (high-high-low two-way two-way divider).
Dimensions
: Length 9.6 cm, width 7.5 cm, thickness 3.2 cm.
Frequency
: 3200HZ (that is, the bass works at frequencies below 3200HZ, and the treble works above 3200HZ).
Power
: 150W.
Impedance
: 5-8 ohms.
Circuit
: The bass line is standard 12db/oct, the treble line is standard 12db/oct, and then separated into two channels by a current-limiting over-current protection sheet. The function of the protection sheet is to automatically disconnect when the current is too large to protect the treble. After burn out, it will automatically close when the current returns to normal, which is a kind of high-pitched protection.
Materials
: The inductor is wound by oxygen-free copper, and each of the bass and treble uses a rectangular cylindrical coil; the treble capacitor uses professional MKP audio metalized capacitors, with an error of ±3%, high withstand voltage up to 400V, and better prevention of low frequency peaks The voltage crossed and burned the tweeter. The bass capacitor adopts an ordinary non-polar capacitor 100V withstand voltage and a capacity of 6.8UF. The design is reasonable, the appearance is exquisite, and the sound quality is also excellent.
