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:
20 Hz to 20kHz (in 1/6 octave steps)
SUBWOOFER:
20 Hz to 200 Hz (in 1/6 octave steps)
8
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)
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 following the steps below.
1 Press and hold the [Rotary Encoder] for 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 for that 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 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)” (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
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 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 (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.
