From the Commander 6 Select the band by rotating the [Rotary encoder], and press the [Rotary encoder]. Band: FRONT/REAR/CENTER 1 to 10 SUBWOOFER 1 to 5 7 Adjust the frequency by rotating the [Rotary encoder], and press the [Rotary encoder). fc: FRONT/REAR/CENTER 20Hz to 20kHz (in 1/6 octave steps) SUBWOOFER 20Hz to 200 Hz (in 1/6 octave steps) 8 Adjust the bandwidth (Q) by rotating the [Rotary encoder], and press the [Rotary encoder]. 0: 0.5/1 .0/ 1.5/2.0/2.5/3.0/4.0/5.0 (8 steps) 9 Adjust the level by rotating the [Rotary encoder], and press the[Rotary encoder]. Level: -12 to +12 dB (in 0.5 dB steps)*3 *3 When ImprintEQ is enabled, 6 to +6 dB (in 0.5 dB steps) 10 To adjust another band, repeat Steps 6 through 9. 11 To adjust another channel, repeat Steps 5 through 10. • You can listen with Defeat OFF (adjusted setup values) or with Defeat ON (Initial value) to compare, by f ollowing the steps below. 1 Press and hold the [Rotary Encoder] lor at least 2 seconds while in the adjustment mode. 2 Rotate the [Rotary Encoder] to switch on/off Defeat. and listen to compare. 3 To exit, select "OFF" and then press [ ~ ]. • You can mute the channel you are adjusting. 1 Press [MUTE] while in the adjustment mode to mute the channel. 2 To cancel muting, press [MUTE] again . 12 When the setting is complete, press and hold [ ~] for at least 2 seconds. • If [ ~ ] is pressed during setting, the unit returns to the previous item. • This function is not available when Defeat is set to ON. • When the speaker is set to the "OFF" mode, the parametric equalizer fo r tha t speaker cannot be set. Refer to "Setting the Speaker System (System Select)" (page 37)/"Setting the Speakers (Speaker Setup)" (page 38). • Check the playable frequency ranges ofthe connected speakers before making equalizer adj ustments. If the speaker's playable frequency range is 55 Hz to 30 kHz,for example, adjusting the 40 Hz or 20 Hz band has no effect. Moreover, you may overload and damage the speakers. • After the setting, it is recommended to store the setting contents on the unit. For details, ref er to "Storing the Preset Values (Preset Store)" (page 36). About the Crossover (X-Over) Crossover (X-Over): This unit is equipped with an active crossover. The crossover limits the frequencies delivered to the outputs. Each channel is controlled independentl y. 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 f requency range outside that recommended may cause damage to the speakers. For the recommended crossoverfrequencies ofAlpine speakers, refer to the respective Owner's Manua l. We are not responsible fo r damage or malfunction ofspeakers caused by using the crossover outside the recommended values. 48-EN
