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.

To do this, follow the procedures below. 1 Bring your vehicle to a complete stop at a safe location. Engage the parking brake. 2 Keep pushing the foot brake and release the parking brake once then engage it again. 3 When the parking brake is engaged for the second time, release the foot brake. • For automatic transmission vehicles, place the transmission lever in the Park position. Now, the locking system for the Setup operation has been released. Engaging the parking brake can reactivate the Display Setup Menu, as long as the car's ignition has not been turned off. It is not necessary to repeat the above procedure (1 through 3) of "To display the Display Setup Menu screen." Each time the ignition is turned OFF, perform the procedure of "To display the Display Setup Menu screen." The following steps 1 to 6 are common operations to each "Setting item" of Display Setup. Refer to each section for details. 1 Touch [Setup] on the Home screen. The Setup main screen is displayed. 2 Touch [Display Setup]. The Display Setup screen appears. • You can display the Display Setup screen from each application screen. Touch [ Display] on any application screen (video mode). 3 Touch the desired application. 20 Hz (Different from actual display) HPF cut-off LPF cut-off frequency 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. • "Video" can be selected while a video is playing. • The camera names set under the "AUX Camera" settings are displayed. The camera names are not displayed when "Off" is set (page 32). 4 Touch [ ] of the desired item. Settable items differ depending on the application.
