Dual Op Amp Preamp without Magnification Crossover NE5532 Subwoofer Electronic Crossover Linkwitz-Riley Divider Board

Introduction of Linquez Rayleigh filter divider electronic two frequency divider board This module is designed for an upgraded electronic frequency divider Compared with the previous version the advantage of this module is that it has no magnification and is not affected by magnification It is a pure signal frequency divider module and will not be affected by high magnification Input and output Resistance is also added to the terminal which effectively avoids overload distortion high popping and noise and has good adaptability to various 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 Specification Frequency division structure Linkwitz RileyBoard structure stereo four channel output left and right channel mid treble left and right channel heavy bass Op amp chip high precision NE5532Crossover slope 12dB Oct 12dB low 2nd oroder low frequency 6dB high frequency Crossover frequency 160Hz default regular version about 80Hz high frequency Chip type high precision and low noiseCapacitor type correction capacitorResistance type high precision metal film resistorOp amp bandwidth 10MHzOp amp slew rate 9V μsRecommended power supply dual power transformer 12VPackage type DIP plug in typeNumber of pins 8P dual op ampOperating temperature range normal temperature environmentDevice Marking NE5532Op amp featur
