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.
