HPF cut-off LPF cut-off
frequency frequency
• 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.

octave steps)
5
Press SOURCE/POWER to select desired slope.
Adjustable slope: 0 (FLAT (OFF)), 1 (6 dB/oct.),
2 (12 dB/oct.), 3 (18 dB/oct.),
4 (24 dB/oct.)
6
Turn the Rotary encoder to select the desired
output level.
Adjustable output level: -12 to 0 dB.
To store the adjusted contents
1) Press and hold, for at least 2 seconds, any one of the
preset buttons (1 through 6) into which you wish to store
the adjusted contents.
7
For setting another channel, repeat the steps 3 to 6.
