• 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,
• 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.
content.
• You cannot adjust the crossover frequency higher than the HPF or
lower than the LPF.
• Use the recommended crossover frequencies of the speakers being
used for setting the crossover. Adjusting to a frequency outside that
recommended range might cause damage to the speakers.
For the recommended crossover frequencies of Alpine speakers,
refer to the respective Owner's Manual.
Alpine is not responsible for damage or malfunction of speakers
caused by improper crossover settings.

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.
