From the Commander

Select the band by rotating the [Rotary encoder], and

press the [Rotary encoder].

Band:

FRONT/REAR/CENTER: 1 to 10

SUBWOOFER: 1 to 5

Adjust the frequency by rotating the [Rotary

encoder], and press the [Rotary encoder].

fc:

FRONT/REAR/CENTER:

20 Hz to 20kHz (in 1/6 octave steps)

SUBWOOFER:

20 Hz to 200 Hz (in 1/6 octave steps)

Adjust the bandwidth (Q) by rotating the [Rotary

encoder], and press the [Rotary encoder].

Q:0.5/1.0/1.5/2.0/2.5/3.0/4.0/5.0 (8 steps)

Adjust the level by rotating the [Rotary encoder], and

press the[Rotary encoder].

Level:-12 to +12 dB (in 0.5 dB steps)*3

*3When ImprintEQ is enabled, 6 to +6 dB (in 0.5 dB steps)

To adjust another band, repeat Steps 6 through 9.

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 following the st eps below.

1 Press and hold the [Rotary Encoder] for at least 2

seconds while in the adjustment mode.

2 R otate 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.

When the setting is complete, press and hold [ ]

for at least 2 seconds.

•If [ ] is pressed during setting, the unit returns to th e 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 for that speaker cannot be set. Refer to “Setting the

Speaker System (System Select)” (page 37)/“Setting the Speakers

(Speaker Setup)” (page38).

•Check the playable frequency ranges of the connected speakers

before making equalizer adjustments. 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, refer to “Storing the Preset Values (Preset

Store)” (page36).

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

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.

•HPF (high pass filter): Cuts the lower frequencies and allows higher

frequencies to pass.

•LPF (low pass filter): Cuts the higher frequencies and allows l ower

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 (0 dB/oct) to bypass the HP or LP filters.

•Do not use a tweeter without the HPF on or set to a excessive 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 values.
