Setting the Bass Type (CDA-9811 only). Alpine CDA-9813, CDA-9815, CDA-9811

Setting the Bass Type (CDA-9811 only)

This function allows for 3 different bass type settings. Select the one that appeals to you the most.

1

Press and hold CENTER f for at least 2 seconds to set the bass type.

2

Press g or f within 15 seconds to select the

desired type (1 through 3).

TYPE 1 will sound best if you have a subwoofer in your system. Use TYPE 2 or 3 if you are using small diameter speakers.

3

Press and hold CENTER f for at least 2 seconds to return to normal mode.

• Bass center frequency and bass band width previously set are replaced when selecting TYPE 1 through 3. When bass type is set to OFF, your previous settings are restored.

• Bass type is not selectable when connected to an external audio processor.

Adjusting the built-in Crossover

(CDA-9811 only)

The High and Low Pass Filters on this unit can be adjusted to suit your personal taste.

1

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

HPF - <Press momentarily>

→ LPF* - <Press momentarily>

→ normal mode - <Press and hold for 2 seconds> → HPF

* When the subwoofer output of this unit is turned off, LPF and phase are deactivated.

2

Press g or f to select the desired setting.

HPF (Setting the High Pass Filter):

FLAT (OFF)

↔ 80Hz ↔ 120Hz ↔160Hz

All frequencies above the selected cutoff are output.

About the Crossover

(CDA-9815/CDA-9813 only)

Crossover:

This unit is equipped with an active crossover. The crossover limits the frequencies delivered to the outputs. Each channel is controlled independently. Thus, each speaker pair can be driven by the frequencies for which they have been optimally designed.

The crossover adjusts the HPF (high pass filter) or LPF (low pass filter) of each band, and also the slope (how fast the filter rolls off the highs or lows).

Adjustments should be made according to the reproduction characteristics of the speakers. Depending on the speakers, a passive network may not be necessary. If you are unsure about this point, please consult your authorized Alpine dealer.

• 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.
