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. 4.2ch (FRONT/REAR/SUBW.) mode Low range speaker Rear high range speaker Front high range speaker Cut-off frequency (1/3 octave steps) Slope HPF LPF HPF LPF ---- 20 Hz 200 Hz FLAT, 6, ---- 12, 18, 24 dB/oct. 20 Hz 200 Hz FLAT, 6, ---- 12, 18, 24 dB/oct. ---- 20 Hz 200 Hz FLAT, 6, ---- 12, 18, 24 dB/oct. ---- Level 0 to -12 dB 0 to -12 dB 0 to -12 dB Low range High range (Different from actual display) 2.2ch (3WAY) mode Low range speaker Mid range speaker High range speaker Cut-off frequency (1/3 octave steps) HPF LPF ---- 20 Hz 200 Hz 20 Hz - 20 Hz 200 Hz 20 kHz 1 kHz - 20 kHz, (20 Hz ~ ---- 20 kHz)* Slope Level HPF LPF ---- FLAT, 6, 12, 18, 24 dB/oct. 0 to -12 dB FLAT, 6, 12, 18, 24 dB/oct.
