Description
Description:The advantage of this module is that it has no magnification and is not affected by magnification. It is a pure signal frequency division module and will not be affected by high magnification. Resistance is also added to the input and output ends, which effectively avoids overload distortion, high popping and noise. It has good adaptability to all kinds of audio power amplifiers.The electronic crossover is known for its excellent performance and stable amplitude, and its transmission characteristics take into account both performance and sound quality.
This product is a classic product of Linkwitz-Riley filter used for active electronic frequency division of two-way power amplifiers. Its frequency division frequency is 160Hz, which belongs to the subwoofer frequency division type.
This frequency divider module adopts electronic two-way frequency design, the overall structure is simple, and the sound quality is good. It is set as a stereo four-channel output structure. It inputs stereo 2.0 left and right channel signals and outputs 4-channel signals, which are divided into left treble, left bass and Right treble and right bass can directly output 4 channels of audio signals to the power amplifier.
