Alfa Romeo 4C Alpine Radio 2018 Manual page 58

• 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 recom-
mended crossover frequency of the connected speak-
ers. 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.
