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.
