About
the
Crossover
(X-Over)
Crossover (X-Over):
This unit is equipped with an active crossover. The crossov
er
limits the
frequencies delivered to the outputs. Each channel is controlled
independentl
y.
Thu
s,
each speaker pair can be driven by the fr
eq
uencies
for which they have been optimally designed.
The crossover adjusts the
HPF
(high
pa
ss filter) or LPF
(l
ow
pa
ss filter)
of
each band, and also the slope (how fast the filter rolls
of
f the highs or
lows).
Adjustments should be made according to the reproduction
ch
aracte
ri
stics
of
the sp
ea
kers. Depending on the speakers, a passive
network may not be necessary. If you are unsure about this point, please
consult your authorized Alpine d
ea
ler.
