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 reproduc-
tion characteristics of the speakers. Depending on the
speakers, a passive network may not be necessary. If you
are unsure about this point, consult your authorized
Alpine dealer.
