Notes
• 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.
