Crossover network
The
Because of this, there is no need for a passive network between the speakers and amplifiers and the amplifiers are fully independent, thus eliminating the problem of interference and making it possible to achieve the optimum acoustic space by dividing the playback frequencies in a way suited to the capacities of the speakers.
This adjustment requires special knowledge and experience. Should problems arise, please see your authorized Alpine dealer.
Adjust the high pass filter (H.P.F.) and low pass filter (L.P.F.) and set the slope (filter response attenuation slope) for the different bands.
Make the adjustments according to the playable frequency ranges and frequency responses of the connected speakers.
