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.

Slope

• HPF (high pass filter): Cuts the lower frequencies and allows
the higher frequencies to pass.
• LPF (low pass filter): Cuts the higher frequencies and allows
the lower 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 or LP filters.
• 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
low frequency content.
