Alpine CDA-118M - Speaker and Filter Adjustments; Parametric and Graphic EQ; Time Correction Procedures

34-EN
The setting of Parametric EQ/Graphic EQ Adjustment, Time Correction
and X-Over can be adjusted in this mode.
Adjusting the Parametric Equalizer Curve
You can modify the Equalizer settings to create a response curve more
appealing to your personal taste. To adjust the Parametric Equalizer
Curve, set the EQ mode to PARAMETRIC EQ. For details, refer to
“Setting EQ mode” (page 36).
1 After selecting EQ ADJ (Parametric EQ) from the
Sound Field Adjustment mode, turn the Rotary
encoder to select the band adjustment, and then
press
/ENTER.
BAND1 BAND2 BAND3 BAND4 BAND5 BAND1
2 Turn the Rotary encoder to select an item to
adjust, then press
/ENTER.
Frequency Adjustment
3 -1 Turn the Rotary encoder to select frequency
bands.
Adjustable frequency bands:
20 Hz to 20 kHz (in 1/3 octave steps)
BAND1: 20 Hz~80 Hz (63 Hz)
BAND2: 50 Hz~200 Hz (150 Hz)
BAND3: 125 Hz~3.2 kHz (400 Hz)
BAND4: 315 Hz~8 kHz (1 kHz)
BAND5: 800 Hz~20 kHz (2.5 kHz)
Level Adjustment
3 -2 Turn the Rotary encoder to adjust the level.
Adjustable level: –6 to +6 dB
Bandwidth (Q) Adjustment
3 -3 Turn the Rotary encoder to set the bandwidth (Q).
Adjustable bandwidth: 1, 1.5, 3
4 To adjust another band, repeat steps 1 to 3 and
adjust all bands.
• The frequencies of adjacent bands cannot be adjusted within 4 steps.
• While adjusting the Parametric EQ, you should consider the
frequency response of the connected speakers.
Adjusting the Graphic Equalizer Curve
You can modify the equalizer settings to create a response curve more
appealing to your personal taste. To adjust the graphic equalizer curve,
set the EQ mode to GRAPHIC EQ. For details, refer to
“Setting EQ
mode” (page 36).
1 After selecting EQ ADJ (Graphic EQ) from the Sound
Field Adjustment mode, turn the Rotary encoder
to select the band adjustment, and then press
/ENTER.
BAND1 BAND2 BAND3 BAND4 BAND5
BAND6 BAND7 BAND1
BAND-1 (63 Hz) / BAND-2 (150 Hz) / BAND-3 (400 Hz) /
BAND-4 (1 kHz) / BAND-5 (2.5 kHz) / BAND-6 (6.3 kHz) /
BAND-7 (17.5 kHz)
2 Press /ENTER to activate the level adjusting
mode.
3 Turn the Rotary encoder to adjust the level.
Adjustable output level: –6 to +6 dB
4 To adjust another band, repeat steps 1 to 3, and then
adjust all bands.
Adjusting the Time Correction
Before performing the following procedures, refer to “About Time
Correction” (page 37).
1 After selecting TIME CORRECTION from the Sound
Field Adjustment mode, turn the Rotary encoder
to select the band adjustment, and then press
/ENTER.
2.2ch (3WAY) System
4.2ch (FRONT/REAR/SUBW.) System
2 Press /ENTER to activate the Time Correction
input mode.
3 Turn the Rotary encoder to adjust the distance (0.0
to 336.6 cm).
L = (distance to farthest speaker) – (distance to other
speakers)
Refer to “Time Correction Value List” on page 37.
4 Repeat steps 1 to 3 to set another speaker.
Set these values to achieve simultaneous sound
propagation to the listening position.
