Alpine PXI-H990 40, Crossover network

40-EN

Settings/Adjustments

Crossover network

The PXI-H990 is equipped with an active dividing network allowing the bands to be split before

amplification by the power amplifier.

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.
