About the Crossover (X-Over)

Crossover (X-Over):

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 (0 dB/oct) 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 X-Over and Switching the Phases

This section describes how to adjust X-Over. Before working on this, refer to “About the Crossover (X-Over)” (page 26).

Hint for adjusting the subwoofer

If the subwoofer is installed on the rear deck, setting a gentle L.P.F. slope (for example 6 dB/ oct.) makes the sound localization more to the rear. This can also affect the acoustic localization of the front.

Hints for adjusting the high range

Depending on the speaker, inputting low frequency component signals (about 2 kHz or less) with the H.P.F. adjustment could result in distortion. If so, set a steep slope (for example

30 dB/oct.).

When doing so, adjust so that the mid and high range sounds do not separate.

Normally use with the L.P.F. off. If the high range is too strong, we recommend adjusting for a gentle slope.

Hint for adjusting the low range

When a subwoofer is connected and you are using a speaker with a low range of under 10 or 12 cm (3-15/16” or 4-3/4”), setting the low range H.P.F. to “OFF” can result in distortion when low frequency components are input.

If so, set the H.P.F. slope to a value suited for the speaker’s frequency response.
