Adjusting X-Over and Switching the

Phases

This section describes how to adjust X-Over. Before working on this,

refer to “About the Crossover (X-Over)” (page 48).

Note on adjusting the subwoofer

If the subwoofer is installed on the rear deck, setting a gentle

LPF slope (for example 6 dB/ oct.) makes the sound localization

more to the rear. This can also affect the acoustic localization of

the front.

Note on adjusting the high range

Depending on the speaker, inputting low frequency component

signals (about 2 kHz or less) with the HPF adjustment could

result in distortion. If distortion occurs, set a steep slope (for

example 30 dB/oct.).

Adjust so that the mid and high range sounds do not separate.

Normally use with the LPF turned off. If the high range is too

strong, we recommend adjusting for a gentle slope.

Note on adjusting the low range

When a subwoofer is connected and you are using a speaker

with a low range of under 10 or 12 cm (3-15/16” or 4-3/4”),

setting the low range HPF to “OFF” can result in distortion when

low frequency components are input.

If so, set the H.P.F. slope to a value suited for the speaker’s

frequency response.

Press [FUNC.].

Rotate the [Rotary encoder] to select “Sound Field

Adj.”, and then press the [Rotary encoder].

Rotate the [Rotary encoder] to select “X-Over,” and

then press the [Rotary encoder].

The X-OVER screen is displayed.

Press and hold [CHANNEL] for at least 2 seconds.

Rotate the [Rotary encoder] to select either “L+R” or

“L or R,” and press the [Rotary encoder].

L or R: Channels R and L can be set independently.

L+R: Both R and L channels are set at the same value

(The initial setting).

• When you switch from “L or R” to “L+R,” choose which adjustment

of the R and L channels to be applied.

1 Select either “L R” or “R L” by rotating the [Rotary

encoder], and press the [Rotary encoder].

L R: The adjustment of the L channel is to be applied to

both R and L channels.

R L: The adjustment of the R channel is to be applied to

both R and L channels.

Select the channel you want to adjust by pressing

[CHANNEL].

L+R selected: FRONT HIGH FRONT MID

FRONT LOW REAR CENTER

SUBWOOFER*

FRONT HIGH

L or R selected: FRONT L HIGH FRONT R HIGH

FRONT L MID FRONT R MID

FRONT L LOW FRONT R LOW

REAR L REAR R CENTER

SUBWOOFER*

FRONT L HIGH

If the Subwoofer output is set for Monaural, you can set both

SUBWOOFER 1 and 2.

If the Subwoofer output is set for Monaural, you can set

SUBWOOFER 1 and 2. If the Subwoofer output is set for Stereo, you

can set SUBWOOFER L and R.

• Channels to be set vary depending on the system set in “Setting the

Speaker System (System Select)” (page 37).

Rotate the [Rotary encoder] to select “HPF,” and

then press the [Rotary encoder].

Select the cut-off frequency (fc) by rotating the

[Rotary encoder], and press the [Rotary encoder].

• The frequency that can be adjusted may vary depending on the

channel (speaker). Refer to “About the Crossover (X-Over)”

(page 48).

Adjust the slope by rotating the [Rotary encoder],

and press the [Rotary encoder].

Slope: 0(OFF)/-6/-12/-18/-24/-30/-36 dB/oct*

Neither LPF of Subwoofer nor HPF of Front High can be set at 0

(OFF).

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

press the [Rotary encoder].

Gain: -24 to 0 dB (in 0.5 dB steps)

Switch the phase by rotating the [Rotary encoder],

and press the [Rotary encoder].

Phase: 0°/180°

This will take you back to the Step 6 screen.

Next, select “LPF” in Step 6, and repeat Steps 7

through 10 to adjust HPF.
