About
the
Crossover
Level adjusting
(0 to -12 dB) Output frequency range
• HPF (high pass filter): Cuts the lowerfrequencies and allows the
higherfrequencies to pass,
• LPF (low pass filter): Cuts the higherfrequencies
and
allows the
lowerfrequencies
to
pass.
• Slope: The level change (in
dB)forafrequency
change
of
one octave.
• The higher the slope value, the steeper the slope becomes.
• Adjust the slope to FLAT
to bypass the HP
or
LPfilters,
• Do not use a tweeter without the HPF on
or
set to a low frequency, as
it
may cause damage to the speaker due
to
the lowfrequency content.
•
You
cannot adjust the crossoverfrequency higher than the HPF
or
lower than the
LPF.
• Adjustment should be made according to the recommended crossover
frequency
of
the connected speakers. Determine the recommended
crossoverfrequency
of
the speakers. Adjusting to a frequency range
outside that recommended may cause damage to the speakers.
For the recommended crossoverfrequencies
of
Alpine speakers. refer
to the respective Owner's Manual.
We
are not responsible
for
damage
or
malfunction
of
speakers caused
by using the crossover outside the recommended value.
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. Ifyou are unsure about this point. please
consult your authorized Alpine dealer.
