frequencies to pass.
• Slope: The level change (in dB)
for
a frequency change
of
one octave.
• The higher the slope value. the steeper the slope becomes.
• Adjust the slope
to FLAT to bypass the HP

LPfilters.
• Do not use a tweeter without the HPF on
or
set to a lowfrequency.

adjust the crossoverfrequency higher than the HPF
or
lower than the

• Adjustment should be made according to the recommended crossover
frequency
of
the connected speakers. Determine the recommended

the speakers. Adjusting to

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 uptimally designed.
The
crossover adjusts the HPF (high pass tilter)
or
LPF (low pass tilter)
uf
each band. and also the slope (how fast the tiller rolls
off
the highs
or
lows).
Adjustments should be made according to the reproduction
characteristics
of
the speakers. Dependi
ng
on the speakers. a passive
network may not be necessary. If you are unsure about this point. please
consult your authorized Alpine dealer.
