Analog divider divider
is a circuit inside the speaker device to the input analog audio signal into separate treble, alto, bass and other different parts, and then were sent to the appropriate high, medium, bass speaker playback unit. Did so because of any single speaker can not perfect all the sound playback from a full band.

action principle defined classification of power electronic divider divider divider divider connected in the definition of merit is the sound signals of different frequencies to distinguish, respectively, to the amplification, and then sent to the appropriate speakers in the band and then replay. In the high-quality sound reproduction, the need for electronic frequency processing.
divider
Crossover: Crossover is the speaker in the role of the Amplifier's output signal must go through the filter components in the crossover treatment, so that each unit by a specific frequency signals. Should be scientific, reasonable and precise to design a good speaker of the crossover, speaker unit can be effectively modified the different characteristics, optimize the mix, making each unit exceed and thoroughly deserved to play out their potential to change the frequency response of the band have smooth, accurate audio-visual phase in order to make high, middle, bass player out of the music structured, step, clear, comfortable,
skechers shoes, wide, natural sound quality. Principle from the circuit structure, the divider is essentially constituted by the capacitors and inductors in the LC filter network, the treble channel is high-pass filter, which only high-frequency signals through the resistance to this low frequency signal; bass channel just like anti- , only to stop the bass through the high-frequency signal; tenor channel is a bandpass filter, in addition to one low and one high frequency between the two can crossover, high frequency components and low frequency components

will be blocked. In the actual divider, sometimes in order to balance high sensitivity differences between the woofer, but also join decay resistance; In addition, some also joined by the divider resistors, capacitors, impedance compensation network formed with the aim of the speaker's impedance curve of a number of psychological flat, so that power amplifier driver. Now that almost all the speakers frequency bands using multi-element design reproducing means there must be a device that can be sent to the full-band power amplifier required music signal is divided into treble and bass output, or treble, alto, bass output, can be connected with the corresponding speaker, crossover, is one such device. If the full-band signal is not added directly into the distribution of high, middle, bass unit to go outside in the elements of that part of the frequency response treble, tenor cell damage. After the classification power divider in the power amplifier, set in the speaker, through the LC filter network, the power amplifier output power the audio signal into bass, midrange and treble, was sent to each speaker. Connection is simple, easy to use, but power consumption, there audio valley point, resulting in crossover distortion, and its parameters, some directly related to the speaker impedance, while the speaker impedance is a function of frequency, the larger deviation from the nominal value,
skechers shape ups, so the error also larger, is not conducive to adjustment. Electronic crossover to the weak signal frequency audio equipment, power amplifiers in the front, and then divided with separate power amplifiers, to give each of the audio frequency signal amplification, and then were sent to the corresponding speaker unit. Therefore, because of current low less power available to achieve electronic active filter, adjust more easily to reduce the power loss, and interference between speaker units. Makes the signal loss is small, good sound quality. However, this approach to use separate power amplifiers for each channel, high cost and complex circuit structure, used in professional sound reinforcement systems. Divider, The first is the divider of the crossover point, this should be needless to say. The second is the so-called crossover Road. The third is the divider of the A passive divider, in essence, a few high-pass and low pass filter circuit of the complex, the number of filter circuit which is mentioned above, the But in each filter circuit, there are more refined, in other words, in each filter circuits, can be repeated each filter, the frequency of the filter is the divider of the Capacity of the first order frequency divider is also a sense of structure, while the second divider in the road have been twice each filter, the In fact, the Dual crossovers, both high and low frequency second-order filter In addition to the first order and second sub-frequency band, there are third-order passive crossover, fourth or even sixth-order frequency. The benefits of using high frequency filter attenuation slope in its larger, better frequency, but also to the design frequency compensation circuit (since it is not In theory, the frequency curve after the superposition of two signals, after fully consistent with the original curve, this is a really good crossover), but the high frequency of large power loss, especially in the phase of large,
skechers women, poorly designed sound will be mixed. So instead of the more high-end frequency, the better. 2.0 multimedia speakers on the market, the use of capacitors or RC frequency in the majority, with very little crossover, but with fewer second-order frequency. SB-2000, such as shock wave using a first-order crossover, frequency of use of second order, only the Swans T200A, M200, Edifier S2000, 1900TIII so few only. (Note: there are many high-end speakers uses a second frequency.) Passive crossover network passive crossover network (Crossover Network), the domestic habits called a very complex task. Passive crossover different physical frequency response, and to meet the requirements of the Will feature passive voice is responsible for full-band output amplifier after the band split into different voices, different sizes are sent to the single speaker, the performance of its should be. This emerging multi-way speaker combinations, or Passive crossover components composed of: L / C / R,, L inductance, C capacitance, R resistance, according to the components of the flexible use of frequency division in the frequency characteristics of the network. L inductance: higher frequency of its characteristic is blocked so that only lower frequencies to pass, also known as By the number of lower frequency is determined by the Inductor common materials are: hollow inductors, inductance of iron Gan oxygen, silicon inductors. Gan oxygen iron inductors, silicon inductors typically only require a high inductance value can not be obtained from the hollow inductors with low DC resistance of the occasion was used, the iron core inductor has a magnetic saturation in the high current distortion caused by the nature of the occasion, so core inductance is a product of compromise. C Capacitance: the opposite of its characteristics and inductance, which is the stop frequency is so high frequency is known as By the number of high-frequency capacitance by the capacitance C decision. The unit is Capacitor materials a large variety of passive crossover for use in the capacitor polarity.
inputs and outputs are clearly visible part of the application of crossover
capacitor in the passive crossover in the high range for the range and must be carefully considered on the material, because the relevance of the absolute sound quality, choice capacitance of the material properties are usually single speaker and capacitance by the loss factor, phase loss and price decisions. Alt domain of not more than 30μF capacitance material can be better taken. R Resistance: No cutting frequency characteristics, and applications in passive crossover with inductors, capacitors mix and match for a particular frequency and bandwidth to do amendments to equalization curve, sensitivity change of use. Speaker crossover can be divided into tandem crossover,
shape up shoes, two parallel crossover. Parallel crossover by an absolute majority to become the best speaker crossover selection, the advantage of multi-way system that can be treated as an individual, and any change in one component may affect the high-pass or low pass characteristics. Commonly used passive crossover slopes can be divided into four kinds: first-order slope of 6dB, second-order slope of 12dB, third-order slope of 18dB, fourth-order slope of 24dB. About Active crossover network, also known as active electronic crossover. Because the space inside the car body, speaker installation point, in practice the utilization of the factors that have their existence can not be changed, dumped by electronic crossover with the characteristics of flexibility in the various segments of the crossover frequency, phase, Q value changes when to the best band adjustments, to overcome all kinds of vehicle variables, in order to achieve the best listening environment for the purpose of the car. Electronic crossover is low pass, band pass, high pass filter is formed. Active devices in electronic crossover vehicle between the host and the amplifier,
skechers outlet, electronic crossover can be two-way to multi-way type, but out of the points are each-way shall not be subject to a signal amplifier, If the sub sounds way more the same amplifier will increase. Active electronic crossover advantages of an increased dynamic range of 2, 3, to improve the ability of transient performance, get better on the subwoofer and is compatible with the expansion of the full power of 4, single speaker between the sensitivity of different questions susceptible Control 5, amplifiers work over a fixed band distortion can reduce the number of cut-off 6, the lower impedance changes,
skechers tone ups, get better connected in the general classification of the performance of the top crossover vehicles have eight terminals. English is the input divider labeled , WOOFER two terminals, TREBLE has four terminals, one is negative, the gain of the three is to enhance treble and attenuation joints, respectively, +3 db, 0db,-3db. Connection is: the host incoming connection INPUT subwoofer input signal received WOOFER BASS treble then bass then TREBLE positive sense of personal lyrics, then +3 db, 0db,-3db.
