About the Crossover
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.
2WAY mode
3WAY mode
*
Depending on the response characteristics of the speaker, care should
be taken when setting the response slope of the high range speaker to
FLAT in 3WAY mode, as speaker damage may result (page 21).
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.
• 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.

1 Press the Y  SETUP and f at the same time.
Note
• In this case, the device will be muted.
2 Turn the Rotary encoder to select the desired system
mode, and then press

ENTER .
Note
• When the system mode is changed, the setting items for X-OVER
are displayed. See “Adjusting the Crossover Settings (X-OVER)” on
page 16 to change the settings.
3 After setting, turn the Rotary encoder to select DONE, and
then press

ENTER .
“TURN ACC OFF

ON” will be displayed.
4 Switch the ignition key to ACC OFF.
Depending on the response characteristics of the speaker,
care should be taken when you switch the 2WAY/3WAY
system, as speaker damage may result.
5 Switching the ignition key from ACC OFF to ON.
The change is saved.
Notes
• If you skip the 4th and the 5th steps, the setting results will not be
saved and unit will return to previous mode.
• While playing back music after the vehicle’s ignition is turned off
(STAY ON mode), you cannot adjust the 2WAY/3WAY mode (refer
to “Setting the stay on mode” on page 26).
