The frequency bands of the graphic equalizer are fixed. This makes it

very difficult to correct for undesired peaks and dips at specific

frequencies. The parametric equalizer’s centre frequency can be tuned

to these specific frequencies. Then, the bandwidth (Q) and level are

fine-tuned, independently, to make the necessary corrections. The

parametric equalizer function is an advanced tool for serious

audiophiles.

Setting item: P-EQ

Select L+R or L/R by touching [ ] or [ ] of P-EQ.

When Graphic EQ is adjusted, this setting will be turned off.

• When the speaker is set to the “OFF” mode, the parametric

equalizer for that speaker cannot be set. Refer to

“Setting the

Speakers” (page 30).

• It is not possible to adjust the frequencies of adjacent bands within 8

steps.

• Check the playable frequency ranges of the connected speakers

before making the 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. Additionally, you may overload and

damage the speakers.

• When the Parametric EQ is adjusted, the adjustment for Graphic EQ

becomes ineffective.

Setting item: Speaker Select

Set the connected speaker by touching the respective

[

] or [ ] button.

• Set the speaker which is not connected to OFF.

• Settings above can be carried out even when the speaker is set to

OFF in

“Speaker Setup” (page 31).

• To use the subwoofer in MONO with PXA-H700 or PXA-H701

connected, connect the subwoofer to the subwoofer output terminal

of PXA-H700 or PXA-H701.

Setting item: Multi CH Setup

Adjusting the acoustic image (BI-Phantom)

In most installations, the centre speaker must be placed directly between

the front passenger and driver. Using this function, the centre channel

information is distributed to the left and right speakers. This creates an

acoustic image simulating a centre speaker directly in front of each

listener. Adjusting the centre width in PL II MUSIC (see

“Using the Pro

Logic II Mode” on page 27), makes this function ineffective.

• Avoid stopping, pausing, switching the disc, cueing, fast-forwarding

or switching the audio channel of this unit while making this

adjustment. The setting is cancelled if the Decode mode is switched.

Touch [ ] or [ ] of BI-Phantom to adjust the level.

The level can be adjusted within the range of -5 to +5. The

higher the level, the more the position of the centre speaker is

shifted to the sides.

The BI-Phantom function is turned off by touching [OFF].

• This adjustment is effective when the setting of the centre speaker to

SMALL or LARGE in the speaker setup settings.

• This adjustment is ineffective when the speaker is set Center to OFF

“Setting the Speakers” (page 30).
