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.
