Setting item: Subwoofer To set the rear speaker to On, touch [ ] (Off) or [ ] (On) of "Subwoofer". Rear Speaker Setting You can set the rear speaker output to Off. Setting item: Rear Speaker To set the rear speaker to On, touch [ ] (Off) or [ ] (On) of "Rear Speaker". Defeat Setting If Defeat is On, the Equalizer setting are turned Off. This disables any settings made for these functions. Setting item: Defeat To set the rear speaker to On, touch [ ] (Off) or [ ] (On) of "Defeat". 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.

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. 22-EN
