Although many friends put a lot of money and efforts to preamplifier, unfortunately they may experiences a little frustration in final output. It is hardly difficult to solve this problem to use excellent pre-divider circuit of preamplifier plus multiple power amplifiers, our series of electronic crossover board and amplifier board can perfectly realize your dreams!

Crossover PCBA is constituted by renowned Linkwitz-Riley filter. Linkwitz-Riley filter, mainly for the active filter circuit, for example, it is used in many sophisticated multi-way electronic crossover systems. The characteristics of this filter is up to 4 stages attenuation slope, in other words, every one octave frequency sound energy will be attenuated 24dB, i.e. attenuation slope of -24dB / Oct (Oct ie Octave, an octave interval of the mean). Meanwhile, in the entire audio band (20Hz-20kHz), Linkwitz-Riley filter has a very flat phase response, which is far better than Butterworth filter after filter signal, no phase distortion, which is widely admired by audiophiles.
