About the Crossover

Crossover (X-Over):
This unit is equipped with an active crossover. The crossover
limits the frequencies delivered to the outputs. Each
channel is controlled independently. Thus, each speaker
pair can be driven by the frequencies for which they have
been optimally designed.
The crossover adjusts the HPF (high pass filter) or LPF (low
pass filter) of each band, and also the slope (how fast the
filter rolls off the highs or lows).
Adjustments should be made according to the
reproduction characteristics of the speakers. Depending on
the speakers, a passive network may not be necessary. If
you are unsure about this point, please consult your
authorized Alpine dealer.
