Sound divider prices, quality audio crossover manufacturers

Frequency divider means different sound signals to distinguish, give to enlarge, respectively, and then sent to the appropriate speaker band again reproduced. When high-quality sound reproduction, the need for electronic frequency processing. The divider can be divided into two types: (1) Power Divider: located after the power amplifier is provided in the speaker, through LC filter network, the power amplifier output of the audio signal is divided into bass, midrange and treble, respectively sent to the respective speakers. Connection is simple, easy to use, but power consumption, appear audio valley point, cross-distortion, its parameters and speaker impedance, some directly related to the speaker's impedance is a function of frequency deviation from the nominal value is large, so the error is large, it is not conducive to adjust. (2) electronic crossover: Weak audio signal frequency equipment, located before the power amplifier, and then dividing by separate power amplifiers, to give each audio band signal amplification, and then were sent to the appropriate speakers unit. Due to a smaller current is small it can be used to achieve power electronic active filter, adjustment easier, reducing the interference power loss, and the speaker units. So that the signal loss is small, good sound quality. But this way to use a separate power amplifier for each channel, high cost, complex circuit structure, used in professional PA system.
