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,” page 48), 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 in “Setting the Speakers” (page 42).

Mixing bass sound to the rear channel (REAR MIX)

This function mixes the front channel audio signals to the audio signals output from the rear speakers, improving the sound in the vehicle’s rear seat.

•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 REAR MIX to adjust the level.

The level can adjusted in five steps: -6, -3, 0, +3 and +6. The higher the level, the more bass is output from the rear speakers. (The effect differs according to the software (DVD, etc.).)

The REAR MIX function is turned off by touching [OFF].

•This adjustment is ineffective when the rear speaker setup setting is set to “OFF”.

•For linear PCM signals, the voice is output from the rear speaker regardless of the REAR FILL and REAR MIX setting.

Achieving powerful high volume sound

(LISTENING MODE)

With Dolby Digital, the dynamic range is compressed so that powerful sound can be achieved at regular volume levels. This compression can be cancelled to achieve an energetic sound with even greater power, like the sound in a movie theater.

This function works only in the Dolby Digital mode.

Touch [ ] or [ ] of LISTENING MODE to select STD or MAX.

STD: For powerful sound at regular volume levels

MAX.: For powerful sound at high volumes

•Keep the volume to a level at which sounds outside the vehicle can still be heard.

Adjusting the speaker levels

(OUTPUT LEVEL)

The test tones help to make the volume adjustments of the different speakers. When levels are equal, a strong sense of presence can be heard from the different speakers at the listening position.

•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.

1 Touch [ON] of OUTPUT LEVEL.

Test tone output is repeated for each of the different speaker channels. They will be repeated in the order shown below.
