About the Crossover
Crossover:
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.

• 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.
• You cannot adjust the crossover frequency 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 crossover frequency of the speakers. Adjusting to a
frequency range outside that recommended may cause damage to
the speakers.
For the recommended crossover frequencies 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.
