Adjusting And Storing The Crossover Settings - Alpine CDA-9887 Owner's Manual

HPF cut-off
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.

Adjustable slope: FLAT
* FLAT can be set for the HIGH slope only when User's is selected in
"Setting the Response Slope for the High Range Speaker
(TW Setup)" (page 24). Depending on the response characteristics of
the speaker, care should be taken when setting the response slope to
FLAT, as speaker damage may result. With this unit, a message is
displayed when the response slope for the high range speaker is set
to FLAT.

Turn the Rotary encoder to adjust the output level.
Adjustable output level: -12 to 0 dB.
7
Repeat steps 3 to 6 to make adjustment to the other
bands.
8
When the setting is complete, store into any one of
the preset buttons (1 through 6) by pressing and
holding the desired button for at least 2 seconds.
9
Turn the Rotary encoder to select PROTECT
YES/NO, and then press
adjusted contents.
PROTECT YES
(Initial setting)
• If YES is selected, the adjusted contents are protected and stored into
the preset buttons. When you want to store the parameter into a
protected preset button, "REPLACE NO/YES" can be selected.
• If NO is selected, the preset is stored.

After setting, press and hold
seconds to return to normal mode.
• Pressing /RTN during the procedure will return to the previous
mode.
• If no operation is performed for 60 seconds, the unit will return to the
normal mode.
