[The function of the frequency divider] The frequency divider is also called the sound divider 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 and small lanes and sidewalks on a major highway,they are separated so as not to confuse people and vehicles. 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 a very low-end frequency divider is used,or one or two capacitors are used instead.If the speaker does not have a frequency divider,the sound will of course be messy.A professional frequency divider will make the sound quality of the speaker much clearer,and the high and low levels will be clearly distinguished the treble not only makes it clear,but also strictly prevents the low frequency signal from entering,protecting the tweeter unit.Burn out less often.To increase the strength of the bass,the woofer can be disconnected from the frequency divider,although it will not be damaged,but due to the entry of high frequencies,the bass works in the piston state,and the strength is not as good as the effect of the frequency divider. How to identify the good or bad 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 the oxygen-free copper wire should be used for winding;the higher the withstand voltage of the capacitor,the better,and the non-inductive copper wire should be used.capacitor. Crossover model: H-883,it is a treble + midrange + bass three-way three-way divider.Using standard 12dB second-order design circuit,it belongs to HI-FI high-fidelity type,the material isvery good,the large board is 1162x121x38mm,the high-power 400W,the high-frequency band protection bubble,the board standard is 8 ohms,the actual application is 4-8 ohms,frequency division Point 1250HZ and 5000HZ. Model: H-883 (high,middle and low three-way three-way divider). Frequency point: 1250HZ-5000HZ (that is,the bass works at frequencies below 1250HZ,the midrange works at 1250HZ-5000HZ,and the treble works above 5000HZ). Impedance: 8 ohm design (suitable for 4-8 ohm speakers,when using 4 ohm speakers,the crossover point becomes wider). Circuit: Designed with 12db/oct,the treble,midrange,and bass all use the second-order standard 12dB circuit,and the treble band is limited by current and overcurrent protection bubble: when the current is small,the bubble acts as a wire;when the current is too large,it acts as a load ,consumes and reduces the current,so that the treble is not burned out by excessive current,which is an active protection. High Quality: The inductor is made of oxygen-free copper wire,the bass coil uses 1.2MM wire diameter,the midrange upper limit coil uses 1.1MM wire diameter,the midrange lower limit coil uses 1.0MM wire diameter,and the tweeter coil uses 1.0MM wire diameter;use large The copper wire has sufficient power to make the bass stronger;the capacitor adopts the fever-grade Liwei brand non-inductive MKP capacitor with a high withstand voltage of 400V,which can better prevent the peak voltage from crossing and burning the speaker.Reasonable design,beautiful appearance and excellent sound quality. colour: red-black Material: ABS Package Contents: 1 x Car audio crossover Only the above package content, other products are not included.
