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.

Adjusting and Storing the Crossover Settings (CDA-9815RB/CDA-9813R only)

Before performing the following procedures, refer to “About the Crossover” (Page 19).

1 Press and hold T.CORR/X-OVER for at least 2 seconds.

2 WAY System

2 Press BAND/TEL. to select desired parameter.

LOW (Subwoofer) REAR FRONT LOW (Subwoofer)

3 Press g or f to select desired cut-off frequency point (crossover point).

Adjustable frequency bands: 20Hz to 200Hz (in 1/3 octave steps)

4 Press SOURCE/POWER to select desired slope.

Adjustable slope: 0 (FLAT (OFF)), 1 (-6dB/oct), 2 (-12dB/ oct), 3 (-18dB/oct), 4 (-24dB/oct).

5 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 any one of the preset buttons (1 through 6) for at least 2 seconds into which you wish to store the adjusted contents.

6 For setting another channel, repeat the steps 2 to 5.

7 After setting, press T.CORR/X-OVER to return to normal mode.

Crossover mode is automatically cancelled if no operation is performed within 15 seconds.

3 WAY System

2 Press BAND/TEL. to select desired parameter.

LOW MID-L MID-H HIGH (HI) LOW

3 Press g or f to select desired cut-off frequency point (crossover point).

Adjustable frequency bands:

LOW : 20Hz to 200Hz (in 1/3 octave steps)

MID-L : 20Hz to 200Hz (in 1/3 octave steps)

MID-H : 20Hz to 20kHz (in 1/3 octave steps)

HIGH : 1kHz to 20kHz (in 1/3 octave steps)

4 Press SOURCE/POWER to select the desired slope.

Adjustable slope: 0 (FLAT* (OFF)), 1 (-6dB/oct), 2 (-12dB/ oct), 3 (-18dB/oct), 4 (-24dB/oct).

*FLAT cannot be set for the HIGH slope.

5 Turn the Rotary encoder to select the desired output level.

Adjustable output level: -12 to 0 dB.
