Adjusting the Sound Operation
The Crossover/Time Correction
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 divider 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).

NOTES
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.
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.

When setting the high range HPF filter to FLAT, do not turn
up the volume too much. This may damage the speaker.
