Adjusting Parametric EQ

1

Follow steps ~ to ! on page 24.

• In step Ÿ, select “Parametric.”

2

Select the band—Band1/2/3.

5

Select the frequency (adjustable between 20 Hz – 20 kHz).

• Band 1/2/3 are required to be preset at least 5 steps (frequencies) away from each other. (Only selectable frequencies are shown on the display.)

Ex.: When “1 kHz” is selected for “Band2”

Band1: Low band (20 Hz to 1.2 kHz)

Band2: Mid band (80 Hz to 5 kHz)

Band3: High band (315 Hz to 20 kHz)

3

Adjust the enhanced level for the selected band within the range of –10 to +10.

Activating crossover network

Crossover network function enables to allocate sound signals to different speakers by frequency range.

By activating crossover network, you can make precise adjustments to match the characteristic of each speaker. (See “To adjust reproduced frequency level—Crossover” on page 30.)

Finish the procedure.

• indicator lights up (in sequence with other indicators).

If you have installed the 3-way network speaker system in the car, make sure of the following.

• Before using the system, activate crossover network and preset the appropriate cutoff frequencies for HPF/LPF (especially for HPF); otherwise, it may damage the speakers.

• For 3-way network speaker system, see

Installation/Connection Manual (separate volume).

To cancel Crossover

Repeat the same procedure.

Make sure that “Crossover Off?” appears on the display in step 1 and “Crossover Off OK?” in step 2.

Adjustable items for crossover network

You can adjust the following parameters for crossover network. For details, see pages 30 and 31.

• HPF (high pass filter): For front/rear speakers.

• LPF (low pass filter): For rear speakers and subwoofer*.

• Slope (filter attenuation slope): For front/ rear speakers and subwoofer*.

* You can adjust LPF and slope for subwoofer even though crossover network is deactivated.

To adjust fader and balance

—Fad/Bal

Adjust the fader*—speaker output balance between the front and rear speakers.

* When crossover network is activated, speaker output balance between high-range and midrange speakers is adjusted.

• F12: Upmost—front only

• R12: Downmost—rear only

Adjust the balance—speaker output balance between the left and right speakers.

• L12: Leftmost—left only

• R12: Rightmost—right only

Select “ON” or “OFF.”

• If you connect high-range speakers to

Front or Rear output, select “ON” for the corresponding HPF; otherwise, the speakers may be damaged.

• ON / OFF

ON: Activates the filter.
